Re: [SlimDevices: Unix] ANNOUNCE: piCorePlayer 7.0.0
@Greg
That was it. Things just got seriously better. Thx.
Now the sourceforge access works too. ;)
I figured the sourceforge mirror downloads are taking at least double
the time. ( compiletc >> ~2min vs ~4min)
Now. The pcp-load "help" wasn't that "clear" either. There's been stuff
missing and IMO not correct.
I tried to update it. (Yep, I know. Cosmetics ;) )
I also had to change the examples!
Here is my update proposal for @Paul.
Code:
###ORIG
pcp-load
Version 12.0pCP
Usage: pcp-load [ -i -w -wi -wo -wil -ic -wic -wicl]{s} extensions
-i Loads local extension
-w Download extension only
-wi Download and install extension
-wo Download and create an ondemand item
Adding -c to any -i option will force a one time copy to file system
Adding -l to any -i option indicates load only - do not update onboot or
ondemand
Adding -s to any option will suppress OK message used by apps GUI
Example usage:
Load local extension:
pcp-load -i /mnt/mmcblk0p2/tce/optional/nano.tcz
Download into tce/optional directory, updates OnBoot and installs:
pcp-load -w -i nano.tcz
Download only into tce/optional directory:
pcp-load -w nano.tcz
Use alternative repository, root level
pcp-load -r https://repo.picoreplayer.org/repo
Use alternative repository, override absolute path.
pcp-load -u https://repo.picoreplayer.org/repo/10.x/armv7/tcz
##MY NEW PROPOSAL###
pcp-load
Version 12.0pCP
Usage: pcp-load [-r|-u ] [ -i -w -wi -wo -wil -ic -wic -wicl]{s}
extensions
-i Loads local extension
-w Download extension only
-wi Download and install extension
-wo Download and create an ondemand item
-r Specify repository
-u Specify subsection in repository
Adding -c to any -i option will force a one time copy to file system
Adding -l to any -i option indicates load only - do not update onboot or
ondemand
Adding -s to any option will suppress OK message used by apps GUI
Example usage:
Load local extension:
pcp-load -i /mnt/mmcblk0p2/tce/optional/nano.tcz
Download into tce/optional directory, updates OnBoot and installs:
pcp-load -w -i nano.tcz
Download only into tce/optional directory:
pcp-load -w nano.tcz
Use alternative repository
pcp-load -r https://repo.picoreplayer.org/repo -w nano.tcz
Use alternative repository subsection
pcp-load -u https://repo.picoreplayer.org/repo/10.x/armv7/tcz -w nano.tcz

The process will fill all the RAM and then crash. The "long-term"
depends on the transcoding. In extreme cases it can take 2 hours to fill
12GB and then crash.

I'm gonna try the fix mentioned in the github issue you linked. If it
fail I'll setup a vm on my server and I'll send you credentials. (I'm

Re: [SlimDevices: Unix] ANNOUNCE: piCorePlayer 7.0.0
A Q or better an idea related to the backup function. Which I think is a nice feature. By reading the code I figured that 1. only the effective image size gets backed up - GREAT - and 2. the whole thing gets gzipped 3. I also saw that the space gets checked on the target Now. By definition the backup supposedly works towards attached USB disks only. Hmmh. However. With 2/4/8 GB RAM at hand, a backup of rather small partitions could easily be done and stored on /tmp tmpfs without a USB-disk attached. >From /tmp the image could then easily be transferred via scp to whatever destination. Doing it this way has an IMO huge advantage since you could run all the backups in the house without carrying your USB-HDDs from A2B around. I think this small change could easily be accomplished in the code. And would make the backup function even more useful. \SC :::' my blog - latest: \"The Audio Streaming Series - introducing: tuning kit - pCP (beta)\" ' (http://soundcheck-audio.blogspot.com)::: soundcheck's Profile: http://forums.slimdevices.com/member.php?userid=34383 View this thread: http://forums.slimdevices.com/showthread.php?t=113512 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Well I was wrong. Somehow that spawned script is NOT killed when the
script that spawned it finishes. Maybe I've misunderstood what I've
read. I tried it with a loop that would always iterate 5 times at 1
second intervals, and it kept iterating even after the calling script
had ended. As far as I can tell, that's not standard bash behaviour, so
I'm at a loss to explain it. However, it means that the bit of code, in
my SQLITE-control.sh script above, where squeezelite is started
('/home/tc/restartSQLITE.sh &'), apparently doesn't need changing.

I'm using a Apple USB-C Headphone Jack on my Raspberry Pi Zero W with the latest PCP. I have to change to Alsamixer settings because the default setting is at 40 which is way to quiet for my setup.

I've been looking into this. I have the same issue as described in
'this thread'
(https://forums.slimdevices.com/showthread.php?111540-Alsa-mixer-on-picore-cannot-save)
- in my boot log I see:
Code:
Starting ALSA configuration...alsactl: init:1787: Cannot find soundcard
'USB'...
alsactl: load_state:1763: Cannot find soundcard 'USB'...
.alsactl: load_state:1763: Cannot find soundcard 'USB'...
.alsactl: load_state:1763: Cannot find soundcard 'USB'...
.alsactl: load_state:1763: Cannot find soundcard 'USB'...
.alsactl: load_state:1763: Cannot find soundcard 'USB'...
.alsactl: load_state:1763: Cannot find soundcard 'USB'...
ALSA restore error!
This seems to be due to two separate issues:
1) My sound card isn't called 'USB', it's called 'DAC'
2) Even if named correctly, then timing seems to be an issue - the ALSA
configuration has to happen after the sound card has been detected.
The workaround for 1) is, as you say, to issue 'sudo
/usr/local/sbin/alsactl restore'. So I think there are two places in
the scripts where this has to be issued.
Firstly, it has to be issued when the SQLITE-control.sh script is
looking for the sound card immediately after boot. So that's in the
'find' section. Place that command as indicated in bold:
Code:
find ) # create the file with the kernel name
idVendor=""
idProduct=""
echo "Searching for DAC with idVendor=$idVendor and
idProduct=$idProduct in dmesg" >> /var/log/pcp_DAC.log
dacdev=$(dmesg | grep -m 1 "idVendor=$idVendor,
idProduct=$idProduct" | awk -F usb {'print $2'} | awk -F : {'print $1'})
echo $dacdev > /tmp/DACdevice.txt
if [ -z $dacdev ]; then
echo "DAC not detected" >> /var/log/pcp_DAC.log
else
echo "DAC detected on $dacdev" >> /var/log/pcp_DAC.log
*sudo /usr/local/sbin/alsactl restore*
fi
;;
Secondly, it has to be issued whenever squeezelite (re)starts in
response to the udev rule. I think the best place for that is at the
end of the restartSQLITE.sh script
Code:
#!/bin/sh
attempts=5 # number of tries
count=$attempts
while [ "$(sudo /usr/local/etc/init.d/squeezelite status)" == "Squeezelite
not running." ]; do
if [ $((count--)) -le 0 ]; then
echo "Squeezelite failed to initialize within $attempts
attempts." >> /var/log/pcp_DAC.log
exit 1
fi
echo "Attempting to start squeezelite" >> /var/log/pcp_DAC.log
sudo /usr/local/etc/init.d/squeezelite restart >> /var/log/pcp_DAC.log
sleep 1 # time interval (seconds) between tries
done
*sudo /usr/local/sbin/alsactl restore*
I've updated my scripts quite a bit, mostly so that they don't need to
be personalised with the vendor and product ids, but also to include
that 'imaketherules' script as an option within SQLITE-control. The
output that's visible in the pCP Logs section is also a bit tidier.
I'll post the updated scripts when I've tested them a bit more.

Thank you - your posts in that thread are where I've learned everything I know about this issue! Anyone using this start/stop USB DAC script will end up with a script being called in User Commands, and since that script will know both the name of the DAC and whether it is available, that's a sensible place to make a targeted 'alsactl restore $cardname' call. Issue 2) is solved by the whole USB DAC detection approach, and another targeted call can be made when the DAC appears online. chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=113661 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

To address 2), or at least to not attempt to restore settings to a card that hasn't been detected, the test at line 414 of pcp_startup.sh: Code: if [ "$ALSAlevelout" = "Custom" ]; then would also have to include a check that the card has been detected.

I think that's something that needs fixing in pCP - I think Paul did allude to the possibility that it's 'broken again' :) As I mentioned though, this isn't an issue for people using a udev rule to detect the DAC - the script called by the udev rule can deal with restoring the alsa configuration. chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=113661 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
I think I'm about there now, with a unified script that handles all the
tasks necessary for implementing the udev rules, without any need for
user editing.
1) It can generate the udev rules file automatically from just the name
of the sound card.
2) It can look for the DAC via a user command at boot
3) It can be called by the udev rules to start and stop squeezelite
4) It has its own internal routine to spawn the built-in
/usr/local/etc/init.d/squeezelite script asynchronously.
So the steps are simpler now:
1) Paste the script into a file in your home directory. I've called it
'SQLITE_control.sh' on my system, but you can call it whatever you like,
because the rules it creates will include the script's current name in
them (if you change the filename later, you will need to either edit the
rules file to reflect the new name, or just use the script again to
remake the rules file - step 2 below). Make the script executable with
Code:
chmod +x SQLITE-control.sh
2) Make sure your DAC is plugged in and powered up, then run the script
with the find option and the name of your card ('DAC' in my case) to
create the udev rules file, e.g.
Code:
./SQLITE-control make DAC
3) Include a line in User Commands (bottom of the Tweaks page) so that
the script is called to find the DAC at boot, e.g
Code:
./SQLITE-control find DAC
Again, use your card name where I have DAC.
That's it. Backup and reboot ('pcp br') and it you should be set. If,
like rgro, you don't want squeezelite to stop when your DAC powers down,
you can use either of the options that I mentioned in 'this post'
(https://forums.slimdevices.com/showthread.php?113661-Start-restart-squeezelite-when-plug-in-USB-dac&p=1008560&viewfull=1#post1008560).
This is the current version of my unified script. It's a bit longer
because of the extra functions and some commentary at the top, but just
select it all, then copy and paste it into your file.
Code:
#!/bin/sh
# Script to be used by udev rules that detect when a USB DAC is connected or
disconnected,
# in order to start or stop Squeezelite
# $1 : is the script option: 'restart', 'stop', 'find' or 'make'
# $2 : For 'restart' and 'stop', $2 is the kernel name ($kernel) that is
generated by the udev event
# It is used to match a 'removed' USB device against the device assigned
when the DAC was inserted
# For 'find' and 'make', $2 is the (CARD)name of the DAC, as used in the
squeezelite command string.
# The 'find' option is used at boot to detect which device the DAC is
connected to,
# in the case that the DAC is up before squeezelite attempts to start.
# The 'make' option creates the udev rules file and adds it to
/opt/.filetool.lst so that it is included in the user's backup
# Examples:
# SQLITE-control make DAC
# This will create a rules file in /etc/udev/rules.d.
# The rule number is curently fixed at 10, and the rule name will equal the
card name; in this case 'DAC'
# Run this once, manually from the command line.
# SQLITE-control find DAC
# This will check whether the DAC is connected, and write its kernel id to
/tmp/DAC_kername.txt
# This is intended to be used as a User Command, run at boot, so that the
'stop' option knows which kernel id to look for.
# SQLITE-control restart $kernel and SQLITE-control stop $kernel
# (Re)start and stop squeezelite, respectively.
# These two options are called by the udev rules in response to 'add' and
'remove' events
# They take the $kernel argument that is available when the udev rule is
triggered.
# The associated udev rules are of the form:
# SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="08bb",
ATTR{idProduct}=="2704", RUN+="/home/tc/SQLITE-control.sh restart $kernel"
# SUBSYSTEM=="usb", ACTION=="remove", RUN+="/home/tc/SQLITE-control.sh stop
$kernel"
SQLITErestart() {

Big News.
Starting LMS with LC_ALL=C instead of LC_ALL=en_US=UTF-8 solves the
bug.
My first reaction was "How the f a locale setting can cause a memory
leak of 12GB in an OS used by servers (Netflix included as an
example)??" Because this seems to be a bug of the OS and not of Perl
itself.

That's interesting - I don't think I've encountered any problems with squeezelite not starting up when the TV is powered off. Jivelite yes, squeezelite no. And when I looked at fixing this for Jivelite I recall that I didn't spot anything in dmesg when the TV was turned on.

No, you're right - with the TV powered off at the wall then squeezelite doesn't start. I think what's new in my case is I didn't previously use the wall switch - it only went into standby.

Hi Chill, ThanksI did option 2 and that does, indeed, prevent Squeezelite from shutting down when I place the DAC into standby. Thanks! I think you are correct on the playlist thing. When Squeezelite restarts, it does return to the last track played, but the playlist is reshuffled...which is also somewhat annoying. But, with this fix, that's now a moot issue.

Here is the code in charge of limits
Code:
sub init {
$cache = Slim::Utils::Cache->new;
my $maxPlaylistLengthCB = sub {
my ($pref, $max) = @_;
if ($prefs->get('dbhighmem')) {
$max ||= 2000;
$max = 2000 if $max < 2000;
}
else {
$max ||= 500;
$max = 500 if $max > 500;
$max = 100 if $max < 100;
}
my $cacheObj = tied %Cache;
if ($cacheObj->max_size != $max) {
$cacheObj->max_size($max);
}
};
$maxPlaylistLengthCB->(undef, $prefs->get('maxPlaylistLength'));
$prefs->setChange($maxPlaylistLengthCB, 'maxPlaylistLength');
}
So if you have set the "high memory usage" in LMS settings, it's 2000. I

Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
piCorePlayer was written assuming squeezelite was running and there was a soundcard available. We use squeezelite's connection to LMS to generate things like the Players tabs. Also, things like working out the LMS IP address require a squeezelite /LMS connection. My understanding is squeezelite creates a LMS instance using its MAC address as a unique identifier. If squeezelite has stopped, LMS will forget this players instance after a period. (10 minutes?) So you can't resume the playlist after this period. To LMS this player does not exist. Also, the latest Raspberry Pi code, when they changed their soundcard from ALSA to Headphones, B1 and B2, also introduced a feature where their sound cards where not available unless something was plugged into the HDMI port, but Headphones still appeared. Also it appears that, on the latest RPi400 it doesn't have even have a Headphones sound card. So when you load pCP on it, it will start squeezelite hoping to use the default Headphones soundcard, but it doesn't exist, so squeezelite fails to start. Because squeezelite is not running, there is no connection to LMS, so no player tab, etc. This pCP is completely isolated from the LMS system. This would probably apply to RPi0's as well now, but I haven't checked.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
Seems that I need to get my head around that funny Perl syntax after all. In the LMS settings, I can choose between normal, high and maximum database size. It is set to "high" for machines with 1+ GB of memory, which should be fine. 2 GB is a little too much. scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.2.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

I think this is mostly the case. After Squeezelite was shut down and then restarted, LMS lost its connection to the Squeezelite device and I had to reselect it from the list of available devices. Once reselected, LMS did return to the playlist and the specific track that had been playing when Squeezelite shut down. But, the playlist had been reshuffled when the Squeezelite/LMS connection re-established. So, while LMS did come back to the right song and right playlist, the tracks that would be played after that song were different from what would've been played prior to the shutdown/restart and, in some cases, were tracks that had already been heard.

Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
I'm pretty new to Linux, so Im struggling a bit to implement the script on a DietPi OS I executed the script with the "make" parameter and card name. All went well, except .filetool.lst doesn't exists in DietPi. Code: # add rules file to /opt/.filetool.lst sed -i "\#$rulesfile#d" /opt/.filetool.lst #remove all previous matching entries, to make sure it's only listed once echo $rulesfile >> /opt/.filetool.lst Code: sed: can't read /opt/.filetool.lst: No such file or directory Can I omit this section or should I add the rules file to a different file? 4]4's Profile: http://forums.slimdevices.com/member.php?userid=71351 View this thread: http://forums.slimdevices.com/showthread.php?t=113661 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
That is needed on pCP to make the file changes persistent over a reboot. Does DietPi lose everything when you reboot unless you do something special? If not then you do not need it or anything like it.

Thanks Greg. Seems to be. So when it makes a copy it copies even the empty parts of the partition?

Re: [SlimDevices: Unix] ANNOUNCE: piCorePlayer 7.0.0
Hello I like the new feature to make an image of the SD card. I've managed to do this and now have a 1.3gb file in my tmp/images directory. I've copied this to my PC using WinSCP but now want to delete it from my SD card. When I try it says Permission Denied. Can someone help me delete this file please, I think it's something to do with root privileges but I don't know how to login as root.

hi acanning, I *think* it copies partitions not the SD card.

Re: [SlimDevices: Unix] ANNOUNCE: piCorePlayer 7.0.0
Just read the web page, there is an option to backup all partitions, or just the first two. Only partitioned space is copied. Shrinking partitIons can be a hit and miss process, so I just gzip them to compress the images. Note that gzip is a single threaded process, and can add a long time to large images. If you plan to do this a lot, install the extension pigs.tcz. That is a multithreaded. Gz compression program. Scanning.just use sudo to remove the file. piCorePlayer a small player for the Raspberry Pi in RAM.

Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
I have one further question. I now have two similar udev rule files. One is named: etc/udev/rules.d/10-dac.rules The other is named: etc/udev/rules.d/10-DAC.rules The latter is the current operational one and the former is an accidental (used lower case by accident) duplicate. I cannot figure out how to delete the first file---all I get is a "permission denied" message if I type: "rm /etc/udev/rules.d/10-dac.rules". Seems I can easily create a file, but deleting it is something else. Since I know nothing about Linux, clearly I'm missing something. How do I delete it??

When it's just a permissions thing, you can usually get round it by preceding the command with 'sudo' (for "superuser do"). So try 'sudo rm /etc/udev/rules.d/10-dac.rules'. It's odd that the former version has different permissions though - was it perhaps created by using the 'make' option of my latest script as a User Command under tweaks? chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=113661 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Yes, as Paul said, that is a pCP-specific step. In fact the whole script was developed on, and for, pCP (that's all I know!), so there may well be other parts of the script that are not compatible with DietPi. Most obviously, I expect that DietPi doesn't have a User Commands section on a Tweaks page, so you'd need to find another way of running the 'find' option of the script at boot. Any other problems are most likely to be due to differing paths for certain files I think, so if you want to persevere with this, do post again with details of any problems you encounter. chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=113661 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
I checked all the paths and files. The only missing file was .filetool.lst. Running 'make DAC' works as expected without the .filetool.lst section. And a reboot doesn't remove or change the created rules file. DietPi has a custom boot script, so that's where you'll need to add a line to run the 'find' option: /var/lib/dietpi/dietpi-autostart/custom.sh I do however encounter another problem. When I run the 'find' option it throws an error: Code: sudo: /usr/local/sbin/alsactl: command not found It must be this command that causes the error: Code: sudo /usr/local/sbin/alsactl restore Running the restore option from Putty seems to work just fine. I must confess that I didn't ran the script at boot, but I wanted to test it first so I ran it from Putty. Any suggestions on what might be causing this error? 4]4's Profile: http://forums.slimdevices.com/member.php?userid=71351 View this thread: http://forums.slimdevices.com/showthread.php?t=113661 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
