Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
It's really not recommended to use a wireless connection for hi-def (24-bit) music. Apart from the stuttering, you're going to be getting numerous streaming errors that introduce artefacts and lower the effective definition of what you are listening to. This may be less evident if you don't use an external DAC, as the Touch's internal DAC doesn't produce an audiophile sound anyway, to be fair (I'd compare the sound quality to that of a budget CD player). I have LOTS of hi-def stuff (24/96 stuff from HDTracks and also PS3-SACD rips at 24/88.2 resolution). I have suffered occasional stuttering in the past, but now - in the main - playback is faultless. I have a hard drive directly connected to the Touch's USB input. I'm running the tiny Squeezebox Server. I limit the number of songs/albums loaded onto the Touch at any one time. I move some of my albums into a folder named .Not on Touchy (folder name starts with a full-stop) if it starts to struggle, and it stops those albums being scanned, putting less strain on resources. It's a bit of a shame that I cannot have all my albums available at any one time, but it has solved the stuttering issue for me. I also understand that using a good quality dedicated 3rd party server (wired) is the best solution for stability and quality. -- Dave1972 Dave1972's Profile: http://forums.slimdevices.com/member.php?userid=6 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
So I tested using a wired vs wireless connection today and the problem does indeed seem to be within the wireless configuration but not in the wireless network it self. As soon as I engaged the Wired Nic on the router, load average on the Squeezebox dropped from 1.9 to .5. All choppiness disappeared. This in my opinion is where the problem reside, on the Squeezebox and wpa_supplicant wireless software. Let me explain, in order to get a wired connection to the Squeezebox I installed a Wireless Bridged router next to my Squeezebox and then ran the Cable from the router to the squeeze. Essentially, I still streaming wirelessly to the Squuezebox, I have just offloaded the load from the SqueezeBox to the router. So the question I have is how do we fix that? Is it a bug in wpa_supplican or is the squeezebox under powered? I have not really looked but I am wondering if there is a lighterweight wireless software package that can be installed to test other options -- Lugbutz Lugbutz's Profile: http://forums.slimdevices.com/member.php?userid=46654 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

It is either the software.. A bug in wpa_upplicant or the unit is under powered for streaming 24/96 via wifi. That said no sure I care...

Happens about 20% of the time when starting a 24/96 FLAC album. After the initial re-buffering, the rest of the album plays fine. 16/44 FLAC never has this problem. I am running the latest release SBS and firmware. I just read this entire thread from the beginning, and it sure looks like the combination of wireless (even with good signal strength) along with FLAC decoding is very marginal at starup.

Of course there are several ways of compressing/decompressing files; therefore we have zip, rar, 7zip, etc. In the same way there are several lossless codecs.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Just a quick random update of my experience with 24/96 files. I installed a nightly 7.5.1 when I first got my Touch and while I experienced stutter at the beginning of playing a 24/96 FLAC album, once it was playing the whole album would play through fine, gapless and all. This is on a wired network, ReadyNAS NV+. After many recent problems with CPU usage and perceived slow performance (navigating through the 24,000 odd tracks I have) I have been attempting to upgrade to 7.6 nightlies in the hope that the SQLite support would help improve matters. After lots of clearing out old releases and shutting down mysql etc. it all finally worked and the scan went much quicker than previously. Nice. However, now, 24/96 FLAC files stutter and rebuffer repeatedly on a cycle of about 5 seconds. I really don't want to go back to 7.5.1 with mysql. Suggestions welcomed - and I will keep an eye on the nightlies too. I do notice that CPU on the ReadyNAS is pretty much 98%+ so this is the likely cause rather than the Touch itself but not sure where to look on the server side: PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 2910 root 30 5 72656 63m 5488 R 98.0 6.5 26:47.21 perl -- Peter Galbavy Peter Galbavy's Profile: http://forums.slimdevices.com/member.php?userid=32718 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

I have certain 24/96 files which give me constant rebuffering problems (sometimes, on the same album, certain files are OK and others aren't), when reading them with TinySC from a 1.5Tb LaCie HDD (USB formatted) containing 400Gb of Music (1200 albums). As I reported before, I have no problem when reading these same files with TinySC on the same HDD, when there are only a couple of albums on it. So it seems that the size of the database influences the CPU usage in the Touch when using TinySC (that's also what I noticed by running the top program on my computer after having enabled SSH on the Touch).

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
I am using my Touch almost exclusively with a directly-attached USB drive. I have a number of downloaded 24 bit files from Linn, HDtracks, Analekta, the Classical shop etc, together with 16 bit flac downloads and rips. Obviously I get the stuttering problem. But that is not the end of it: I am getting fed up having to deal with a host of interrelated propblems. 1. the Touch sometimes crashes altogether when playing 24 bit tracks, very occasionally 16 bit flac (doesn't really seem to happen with MP3s or WMAs). It actually turns off and reboots, rescans, sometimes tells me it now can't see the usb drive (which probably got as upset as i did with having its power turned off). 2. Sometimes it just stops playing without crashing 3. This probelm seems to happen far more often when using Ipeng, but it does happen controlling the touch manually. 3A. It also seem to happen more often if you try to change the album while its playing rather than stopping it, deltign the playlist and then satarting again. Especially in Ipeng but manually too. 4 The Touch seems to paicularly dislike my Linn 24 bit download of the Bach St Matthew Passion from Linn. This has 100 tracks in one album . It is not particularly fond of the Hyperion complete Schubert Lieder edition in 16 bit flac which appears as one album too, even though it consists of 37 cds and 800 odd tracks. 5. The Touch also seems to randomly refuse to recognise the usb drive from time to time and says it can't read it. 6. I have noticed that using Ipeng and when accessing manually (but to a lesser extent) it seems to hang while searching sometimes. Even with my relatively modest 6500 tracks no search = what is the bloody point of this thing anyway? The whole thing is beginning to annoy me. I appreciate that my concerns go slightly beyond the topic of this thread, but is pointing me to the following conjecture: I am begining to suspect that the Touch is not really up to to running as a stand-alone player and server at present. I don't know Whether this is because it is underpowered or because the resident squeezeserver is too buggy, but I just don;t think it's quite up to the job. I am guessing that the problem with HD files or big playlists or finding files on the usb drive or interrupting what its doing or even Ipeng are probably just aspects of that problem. I am having problems with my PC at present so I can't compare very effectively running the software ion a separate server. I am getting a QNAP TS 239 NAS in the hope that the touch will work properly with it. If not I am likely to lose patience with it. -- adamdea adamdea's Profile: http://forums.slimdevices.com/member.php?userid=37603 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
After having reported my problems of reading 24/96 files with Tiny SC on a 1.5 Tb HDD containing 1200 albums (http://forums.slimdevices.com/showpost.php?p=542848postcount=155 http://forums.slimdevices.com/showpost.php?p=543088postcount=161) whereas I had no problem when reading these files from a 4Gb USB stick, I decided to make the following test : I erased the contents of my HDD and copied on it the contents of the USB stick. And now, on the HDD, the reading of the 24/96 files is perfect (even when using the other now playing screens : large cover, vu-meters, ...). So my conclusion is the following : TinySC uses far more CPU when playing music files from a huge database. What could be the explanation ? Can we expect an optimization of the CPU usage in a future release of SBS or is the hardware of the Touch too limited, anyway ? -- rotho rotho's Profile: http://forums.slimdevices.com/member.php?userid=33493 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
I don't have that big a library, only about 15000 songs and I don't see that behavior at all. In may case the server gets up to about 10% max when playing files (even 24/96 flac -8) The only time I see it going high is when the scanner is running. Is there a chance the scanner is still running? Are you booting the Touch then plugging in the drive and watching the scan to see when it finishes? (there will always be a scan when you plug a drive in). The only other thing I can think of is if a bunch of retries are happening. There could be issues with a large database when skipping ahead in a playlist, but once a song is playing I don't see how the number of songs can cause a problem other than normal things like fragmentation.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
I will make more tests this evening (I have just finished the restoration of the initial contents of my FAT32 formatted HDD from its twin HFS+ HDD : I didn't want to spend too much time with no backup of my 400 Gb of FLAC files !). In my initial tests, I had carefully waited that the scan process (which lasted around 2 hours, for 1200 albums / 16000 songs) was finished, but then I hadn't rebooted the Touch before listening to music. After having read your posts, I did other tests where I rebooted the Touch, then connected the HDD, then waited for the rescan to finish, and I had the same problem as before. Anyway, as I said, I will make very careful tests this evening. On a french forum, I read that someone had certain compatibility problems with a HDD which had been FAT32 formatted on an Imac. And that's exactly the case of my HDD : I have formatted it in FAT32 by using the Disk Utility. I did not encounted any compatibility problems (on the contrary : the Touch mounts my HDD a lot faster than my Mac, which is more accustomed to the HFS+ filesystem), but perhaps it could be an explanation of my problem. Perhaps I should reformat my HDD with another method.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
I have been following this thread very carefully, because I was very interested in the Touch abilities to read 24/96 files and to go without a PC (by using Tiny SC), and unfortunately, I am experiencing serious problems with that configuration, when using an external HDD (but not when using a USB stick). Here are my findings (when using Tiny SC to read 24/96 files) : 1) The configuration with constant rebuffering problems (so completely unusable) is when connecting my LaCie d2 quadra 1.5 To HDD, which is FAT32 formatted, and which contains for the moment 1200 albums (approximately 16000 flac files, 400 GB used).

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Hi rotho, thanks for the detailed info. The perl line is the actual server, its written in perl so the process is actually the perl interpreter running the server code. Jive is the player (now known as squeezeplay). The Server reads the files and sends the data to the player which decodes it and sends the raw data to the jive_alsa process which sends it to the hardware. All three have to be up and running and getting their share of CPU cycles to make the process work. Its very interesting that the server is running so much higher cpu with the HDD as opposed to the USB stick. Does the server stay at around this number all the time or does it only occasionally get that high? If its running that high most of the time, I would think the next step would be to run some profiling on the perl code to see where its spending its time.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Hi rotho, thanks for the detailed info. The perl line is the actual server, its written in perl so the process is actually the perl interpreter running the server code. Jive is the player (now known as squeezeplay). The Server reads the files and sends the data to the player which decodes it and sends the raw data to the jive_alsa process which sends it to the hardware. All three have to be up and running and getting their share of CPU cycles to make the process work. Its very interesting that the server is running so much higher cpu with the HDD as opposed to the USB stick. Does the server stay at around this number all the time or does it only occasionally get that high? If its running that high most of the time, I would think the next step would be to run some profiling on the perl code to see where its spending its time. I've never done that so someone else who is more familiar with perl profiling will have to help with that.

Does the server stay at around this number all the time or does it only occasionally get that high? Hi John, I have made more tests this evening and here are the successive values of the CPU usage of the perl slimserver.pl process : 1) When using the HDD : 1.1) With a 24/96 file : 32%/46%/43%/45%/52%/30%/42%/51%/47%/44%/32%/51%/36%/35%/57%/31%/37%/48%/24%/54%/38%/31%/56%/32%/37%/50%/27%/48%/38%/30%/... And so on... The server process does never go under 20% and the Touch is constantly rebuffering 1.2) With a 16/44.1 file : 29%/50%/56%/28%/2%/2%/1%/1%/1%/1%/2%/2%/1%/... 2) When using the USB stick : 2.1) With a 24/96 file : 17%/12%/5%/4%/5%/4%/4%/... And no rebuffering problem ... 2.2) With a 16/44.1 file : 23%/4%/2%/1%/2%/1%/... A little precision : for tests 1.1) and 2.1), I was always starting from scratch (Touch unplugged, USB device unplugged), and then I waited until the re-analysis of the files on the USB device was completed. Tests 1.2) and 2.2) were done immediately after tests 1.1) and 2.1), without turning off the Touch. Do you think that the problem could come from the great number of files on the HDD ? If you think it would be useful, I could make a test where I erase the contents of the HDD (I have a complete backup on its HFS formatted twin), and try the HDD with only the same couple of files as on the USB stick. What do you think ? Anyway, thank you very much for your time. -- rotho rotho's Profile: http://forums.slimdevices.com/member.php?userid=33493 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

@John S. Thanks! Lets get the specifics of your system: are you running external server or internal server? External. If external server, how are you connecting, wired or wireless? Wireless. WPA. If external server what format are you streaming? Flac. Do you knopw what compression level the files are at? No. Is there a linux command to tell that? I have the same Claire Martin Linn recording as the poster above. Mine is 113 MB. Are you displaying artworK? Is the artwork changing when you hear a problem? Seems to skip whether art work is displayed or not. Are you running any animated visualizer (VU meters, spectrum analyzer) No. Is the now playing screen scrolling text? Yes. are you viewing pictures at the same time? No. Does the problem happen only at the beginning of tracks or in other places? Only at the beginning. There are many things that can use up CPU cycles that can cause audio problems with high sample rate files. We need to figure out which one it is in your case and come up with a way to get around it.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Thanks, that helps. At this point it looks like there are two possibilities, either connectivity issues (WiFi interference) or flac decompression issues. The easiest thing to test now is go to streaming PCM rather than flac. If its a flac decoding issue that should clear it up. If its a WiFi issue it might get worse. Many people have wifi interference issues even though they have a strong signal. The strong signal does not preclude interference, it just makes it less likely. If its a WiFi issue you night have to go wired to the server.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Let me preface this post by saying the only - and I mean only - reason I bought a Touch was for the 24/96 and 24/88.1 streaming. All of its other capabilities are unimportant to me, other than that fact that it integrates with all my other Logitech squeezeboxen. Here are my preliminary results. Note, the only thing I've done to this thing is add VU meters, so I decided to turn those off, so all of my results are with a static image of the album art. Wireless setup: WPA2/AES, wireless G, awesome signal/bandwidth based upon bandwidth test Wired setup (groan) - straight to gigabit router which his hooked via gigabit to the server. All tests with The Pizza Tapes from HDtracks (Garcia/Grisman/Rice, 24/88.1) Wireless: stutters with native flac encoding for first few seconds. Gaps between tracks. Wireless: no stuttering with streaming wav files from server (disable native flac in server settings) but still gap between tracks. Wired: no stuttering no matter what I do but gaps between tracks. Logging in and running top indicates for the stuttering setup, there are extended periods (several seconds) where the CPU state is 0% idle, meaning it's maxed out. This is bad. I also saw a several second period where the CPU state was 100% sirq. CPU load is still pretty high with other settings but I don't care so long as it plays hirez flac files just like redbook flac files. -- Leigh Leigh's Profile: http://forums.slimdevices.com/member.php?userid=10619 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Tonight I tried and tried to get it to stutter or do anything wrong and nothing worked, it played flawlessly no matter what. 24/96 -8 flac, over WiFi to the server with spectrum analyzer or VU meters, long name so text scrolling in the now playing screen. I tried slideshow over WiFi as well. It just sat there and worked. Its hard to debug something when when you can't make it happen. The worst average CPU was about 50% which was when using VU meters. Once every several minutes the CPU utilization would go up to 95% for a very short time, but still no interruption to the music. The spikes didn't seem to have any relation to the music, it wasn't at the beginning or end of a track, just somewhere in the middle. The VU meters were interesting, when playing a 16/44,1 wav file turning on the VU meters increased the CPU usage a lot, but when playing a 24/96 -8 flac turning on the VU meters made hardly any difference.

JohnSwenson;538770 Wrote: Tonight I tried and tried to get it to stutter or do anything wrong and nothing worked, it played flawlessly no matter what. 24/96 -8 flac, over WiFi to the server with spectrum analyzer or VU meters, long name so text scrolling in the now playing screen. I tried slideshow over WiFi as well. It just sat there and worked. Its hard to debug something when when you can't make it happen. The worst average CPU was about 50% which was when using VU meters. Once every several minutes the CPU utilization would go up to 95% for a very short time, but still no interruption to the music. The spikes didn't seem to have any relation to the music, it wasn't at the beginning or end of a track, just somewhere in the middle. The VU meters were interesting, when playing a 16/44,1 wav file turning on the VU meters increased the CPU usage a lot, but when playing a 24/96 -8 flac turning on the VU meters made hardly any difference.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Curious. I removed the thumb drive from the USB port and changed an HDTracks album (World's Greatest Audiophile Vocal...) from -0 to -8. This is the one that stuttered before. It all played fine on the wired Touch, no stuttering. After reinstalling the thumb drive with the jpegs, and halting the installation of the inbuilt server, I tried again. The -8 flacs played without problem. It looks as if either something was consuming memory when I first played these tracks, and that caused a problem, or the problem was something specific to the HDTracks files that is permanently cured by re-encoding the flac.

Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Sorry I've been off this for a few days, trying to work on other things. Anyway it looks like we seemed to have settled down to a few people have problems with 24/96 at higher compression when using wiFi to an external server. In some cases wired fixes these. First off, does anybody have any problems with an form of 24/96 when WIRED to an external server? From what I'm reading it looks like its a wiFi issue. When using WiFi wav seems to work and flac -0 seems to work. Higher compression wav seems to work when transcoded to PCM. Does anybody have a situation where flac -0 or wav does NOT work? If the above is true, then it looks like we just have to worry about streaming over WiFi with flac greater than -0. Does this seem to be the situation? Given that wavs seem to work it does not sound like its a transmission bandwidth issue. This seems to point to it being something inside the touch, some sort of interaction between WiFi and higher level flac decompression. IF the builtin server is not running the amount of free memory should be plenty to handle the needs of this operation so I don't think that is the first place to look. To me it seems like there are two reasons stuttering might be happening, either data throughput is not fast enough for some reason, or the code working with that data is not running (swapped out of memory or process not running). Lets try and come up with some possible scenarios and see if we can come up with some tests to try and pinpoint whats happening. (the problem here is that I don't have the problem so I can't go off and run these tests myself, its going to have to be those that DO have the problem who run the tests) Some of the previous tests have noticed that the CPU will max out occasionaly, but only for short periods of time. One of the tests seemed to show that low average with occasional max bursts works fine, but much higher average without the max bursts does cause problems. This sort of makes sense since there are fairly large buffers in the player code, so short interruptions in the data flow should not be a problem. One option to try here is increase the buffer size in squeezeplay and see if that improves things. Another place I would like ot look at is the WiFi itself. There are various levels of encription in use in WiFi, no encryption, WEP and several levels of WPA. I would like to see if varying the encryption type makes any difference. So could any of you that have the problem try different encryptions levels on your WiFi and report back. Another thing to look at is process run statistics, see if either the WiFi or jive process is not getting run for significant periods of time. Another thing to check is if there is any significant swapping going on. Given the fairly large amount of free memory there SHOULDN'T be any swapping happening, but its a good idea to check. I'll leave it at that for now.

Any drive (flash, HDD, whatever) plugged into the USB OR any SD card plugged in the builtin server starts up and IT takes a large amount of memory.

Yep, reflac-ing to 0 cured the issue - can provide the original and re-flaced files for debugging purposes ~80MB each - was using coaxial out, digital vol 100%, Cat6 gigabit Ethernet everywhere. This is going to be a pain! -- ziggyb63 ziggyb63's Profile: http://forums.slimdevices.com/member.php?userid=11682 View this thread: http://forums.slimdevices.com/showthread.php?t=77080 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] 24/96 Perfromance Issue ( Solution!)
Hi New to this forum. I'll get the Touch when it is available in Sydney, Australia. I have a QNAP-TS210 NAS. My house is hard-wired (CAT 5). I intend to stream FLAC from my NAS (Study) to my HiFi. I would connect via digital but via L/R analogue to my pre-amp instead. I read alot of mention about 'external server'. What does that mean? A NAS? My old CD player is playing up and rather then getting a new CD player, I am thinkign of ripping all my collection to FLAC and stream via Squeezebox Touch to my HiFi. Can this be done and how will the analgue sound be?
