Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
Hi Triode, Seems to be working like a dream. I did a factory reset, then a firmware update, then I installed your applet. Everything worked just as you described. USB audio is still working brilliantly, and 24/192 still fine from the optical/coax out. I notice there is a Digital Output option in the audio settings. Is this new, or did I just miss it last time? I was going to ask for this, so I'd feel a bit silly if it was there all along! Not a biggie, but I take it it's not possible for all the outputs to work at the same time?

Sorry for the delay replying... USB is now working fine, but I'm seeing problems with 192K over optical/coax. MDAC has trouble locking on at all, and the CDQ locks on but is suffering constant dropouts. I tried swapping back and forth between kernel#5 and #6, and I could consistently get 192K to work ok on #5 but not #6. -- indypants indypants's Profile: http://forums.slimdevices.com/member.php?userid=11608 View this thread: http://forums.slimdevices.com/showthread.php?t=93310 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

I was under the (false?) impression that the Isolator did something to stop the power feed getting through, and that this might stop the hub from working properly (it's powered, yes?).

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
For anyone interested, I've just been playing around with a USB galvanic isolator between the SB Touch and the DAC (Audiolab 8000CDQ). Here are the comments I posted over at Pink Fish. I'm wondering if this is simlar to the effect that others have reported by installing the soundcheck mods? My first impression when I put the isolator in was one of an immediate improvement, but being aware of the potential for a placebo effect i then went on to do a lot of swapping back and forth. However, because of the delay of rebooting the SB Touch between swaps (and not having the most golden of ears), it was not an easy comparison, and to be honest, after a while, I really was starting to think that any difference was in my head. That all changed when I put on Titanium by Kraftwerk (Tour De France album). Playing the opening few seconds of this track has left me with a high confidence level that the Isolator is doing something to tightening up the bass to quite a noticable degree. The sound also seems slightly crisper. I'm still not guaranteeing this isn't my imagination, but if you've got £40 burning a hole in your pocket, I'd recommend giving it a try.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
Hi Trode, I've just got my SB Touch back from JohnW having been itching to try out your modifications for weeks now... Well, your kernal#1 is working brilliantly with 44/48K and HDCD material into both the MDAC and 8200CDQ. I also had a quick try with Kernal#4 and was able to get 192K over SPDIF with no noticable problems (I only tried the MDAC for that). I listened carefully to a few tracks and they seemed fine. What a super job you've done! To be honest, I'd have been happier than a very happy thing just to see it working at all, but looking at how far you've bought this in terms of ease of use installation is incredibly impressive. We owe you and John S a great debt of grattitude, you've clearly put a lot of work into this which we can all now benefit from. Can't thank you enough! I've just ordered the HAMA USB hub from Amazon (£6.49) so looking forward to trying higher def material over USB once this arrives. I've also got a USB Isolator (of the sort you've mentioned) that I want to try once I get some time - I'll report back if you're interested. Forgive my ignorance/curiosity, but I wondered if you had ever worked in an official capacity on this product? Looking at the quality of your work and your depth of knowledge certainly gives me that impression...

Sure it can be setup so that the USB and digital out run at the same

udev is the mechanism by which devices get named. By default your USB
DAC can wind up with different names and card numbers making it
difficult to write asound files, because the names are going to be
different for everybody. There was a udev script posted here a while
back which explicetly looks for any USB audio devices and gives them a
specific name so it's always the same and people can distribute asound
files and have them work on anybodies setup.
Unfortunately it didn't go far enough, the presence of a USB device can
cause the built in DAC or digital out to change THEIR name making any
scheme to have output on two devices at the same time be rather
difficult. This udev script needs to be extended so it names ALL audio
devices, then its much easier since the names will always be the
same.

Hi John,
I've been trying without any luck to get the USB and SPDIF running at
the same time.
To take this one step at a time, I tried the following asound.conf,
which works fine for USB (ignoring the clicks):
pcm.digital {
type hw;
card TXRX;
}
ctl.digital {
type hw;
card TXRX;
}
pcm.usb {
type hw;
card Series;
}
ctl.usb {
type hw;
card Series;
}
pcm.!default usb
However when I change the above to pcm.!default digital and reboot I
get nothing from the spdif outputs unless I unplug the USB cable prior
to rebooting. Not sure how I'm going to get them both working
simultaneously with this being the case :(
I've also tried the original asound.conf, as per (i think) your
suggesiton, replacing the ak4420 alias with the above usb alias but
when I do this, the squeezebox fails to boot up.
Am I doing something silly ? Any suggestions much appreciated.
Tim

Re: [SlimDevices: Touch] Instructions for connecting USB DAC to Touch
Hi John, I've recently been in touch with the designer of my Audiolab 8200CDQ DAC and described the symptoms of the intermittent clicks. Below I've pasted his comments (this is based purely on my description of the problem of course). Is this possibly pointing at an out of date USB driver? If so, can this easily be updated? I'm certainly willing to give it a try if you could guide me through it. All the best, Tim Yes the CDQ will be replaying USB from its DAC's internal Clock (Async USB), and the SB Touch will be streaming the Data, but the SB Touch will not be acting upon the CDQ's Buffer Flow control requests - i.e. it streams the Audio, but does not listen to the request from the CDQ to keep its USB buffer Half Full. The Clicking you hear is when the CDQ's buffer overfills or is allowed to empty - When this buffering error occurs, the CDQ resets its USB buffer pointers and the cycle repeats. Basically, I believe the SB Touch is not managing the Async USB flow control.

So when I set it to 32 in the above post that actually set it to 16. I guess the HRT products will work with S16_LE as well as S24_3LE.

By going through the info in this thread, and doing a bit of hex / binary conversion, I think I've figured out the full list of clean pronto IR codes for the SB touch: 900B 006D 0001 6E91 19E6 0 900B 006D 0001 6E91 0FF0 1 900B 006D 0001 6E91 10EF 2 900B 006D 0001 6E91 11EE 3 900B 006D 0001 6E91 12ED 4 900B 006D 0001 6E91 13EC 5 900B 006D 0001 6E91 14EB 6 900B 006D 0001 6E91 15EA 7 900B 006D 0001 6E91 16E9 8 900B 006D 0001 6E91 17E8 9 900B 006D 0001 6E91 06F9 Add 900B 006D 0001 6E91 0DF2 Arrow down 900B 006D 0001 6E91 09F6 Arrow left 900B 006D 0001 6E91 0BF4 Arrow right 900B 006D 0001 6E91 07F8 Arrow up 900B 006D 0001 6E91 20DF Brightness 900B 006D 0001 6E91 0EF1 Browse 900B 006D 0001 6E91 18E7 Favorites 900B 006D 0001 6E91 05FA Fwd 900B 006D 0001 6E91 44BB Home 900B 006D 0001 6E91 1EE1 Now Playing 900B 006D 0001 6E91 04FB Pause 900B 006D 0001 6E91 08F7 Play 900B 006D 0001 6E91 02FD Power 900B 006D 0001 6E91 1CE3 Repeat 900B 006D 0001 6E91 03FC Rew 900B 006D 0001 6E91 1AE5 Search 900B 006D 0001 6E91 1BE4 Shuffle 900B 006D 0001 6E91 1DE2 Sleep 900B 006D 0001 6E91 01FE Volume up 900B 006D 0001 6E91 00FF Volume down 900B 006D 0001 6E91 23DC Mute 900B 006D 0001 6E91 F10E Power on 900B 006D 0001 6E91 E11E Power off Hope this is helpful, I could not find this info anywhere, and like others, I found that my SB3 codes did not work with the touch.

Re: [SlimDevices: Touch] Instructions for connecting USB DAC to Touch
John, I'm sure I'm not alone, but I just wanted to pass on my thanks for all your hard work on this. You're selfless efforts are very much appreciated. This will benefit an awful lot of people. -- indypants indypants's Profile: http://forums.slimdevices.com/member.php?userid=11608 View this thread: http://forums.slimdevices.com/showthread.php?t=82110 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

I do have a firmware I compiled myself which has a later version of the driver, BUT it doesn't have MP3 or wireless capability. (the wireless code and MP3 code get linked in by Logitech, they have NOT made those publicly available) Its also based on an old firmware package so it won't have some of the latest fixes. If you are interested in trying that I'll see if I can find it and get it to you. John S. Hi John, If you don't mind, I would really like to try your firmware with the updated ALSA driver to see if this helps in my case. I'd be really grateful if you could PM me with details.

Re: [SlimDevices: Touch] ayre QB9 + touch USB
JohnSwenson;602257 Wrote: Some people have run a QB-9 with the Touch without any problems at all. So there has to be something DAC specific, Touch hardware specific or configuration specific. What I would like people to try is different sample rates say 44.1 VS 48 or 88.2 and 96. That should wind up exercising different crystals in the DAC. With a USB interface the rate data is sent to the DAC is NOT determined by the audio crystals but by the processor crystal which may not be given as much care in initial frequency accuracy. The result is that the data rate might be fairly far off from what it should be and the feedback loop in the asynchronous interface may not have enough time to get the computer sending the data at the right rate before the buffer over/under flows. I've been working with some others with async hardware and seeing some very strange things happening. The feedback loop IS working but sometimes the data rate gets set to something very bizarre. Unfortunately I can't get any of this to happen on my Touch so its hard to debug. John S. Hi John, I've been in communication with the software engineer for my async USB DAC (this one http://www.audiolab.co.uk/ProductDetail.aspx?lang=EnTab2=8200CDQ), which is also getting the pops/clicks after applying your mod. He is interested in contacting you to help resolve it. Would you like me to put you in touch?

Re: [SlimDevices: Touch] Instructions for connecting USB DAC to Touch
Hi cocamegadose, thanks for posting those extra tips. I've just given them a try, and I do agree that the click pops are reduced, but for me even one or two is telling me the story that the Async USB just isn't working properly - in which case there is no advanage over spdif. When I ran these symptoms past the designer of my DAC, the reply was this: Sounds like the SB is not handling Async USB correctly as if its not handling the flow control and allowing the USB buffer to over-run / under-run Maybe this will mean more to someone here than it does to me? -- indypants indypants's Profile: http://forums.slimdevices.com/member.php?userid=11608 View this thread: http://forums.slimdevices.com/showthread.php?t=82110 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Instructions for connecting USB DAC to Touch
Hi John, I've got a brand-new SBT and have just tried implementing your
mod in order to connect up to an async USB DAC (Audiolab 8000CDQ). I'm
getting no sound at all over USB, and it is still coming out of the
coax. Below is a dump of some of my files. I'm guessing the status of
stop in the stream0 file is not a good sign. My SBT firmware is 7.5.3
r9283 (it updated itself immediately that I turned it on).
Can you offer any advice as to a possible cause of my problem? I
wondered if it was worth me trying your modified firmware, if you could
point me to it.
Many thanks in advance,
Tim
