Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
Whoa, this is fast-moving thread! I thought I was all caught up, and
suddenly there are another dozen messages! :-)
I'm pretty impressed by chill's script. Nice work. Keeping track of
all that statefulness, via multiple entry points to the script, is
tricky. The self-installation is a nice touch.
I found the thread while looking for something somewhat related, and
thought I'd share my (partial) solution to the USB audio detection
problem. I also happen to have a set of H-K Soundstick speakers, which
I've only recently hooked up to picoreplayer. Keeping things going when
the speakers are turned off or unplugged is an issue.
So... my script relies on polling (which doesn't worry me in the
least), and probably won't cover many corner cases, but it serves my
purposes. It relies on the USB audio device coming and going from
/proc/asound when it's un/plugged.
The script is invoked as one of the "user commands" on the Tweaks page.
The copy here is trimmed from the script I actually run, since mine does
some other unrelated stuff as well, but I don't think I've introduced
any new bugs. It's pretty simple -- hope it might help someone.

#!/bin/sh

Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
I only use "force" option on the command line. I'm wondering if $0 gets set correctly if calling from a script.

Thanks Greg. I had noticed the 'force' option, but hadn't looked beyond
the comment: "# Force should only be used for testing purposes."
But now I see that it's a brute force replacement for the 'restart'
option. So I've given it a try on my own setup, i.e. I replaced
Code:
result="$(sudo /usr/local/etc/init.d/squeezelite restart)"
with
Code:
result="$(sudo /usr/local/etc/init.d/squeezelite force)"
And now - the weirdest thing - Squeezelite won't restart on my test
setup! The running process is killed, and the PIDFILE is deleted, but
the part of the init.d script that does the 'start', i.e. '$0 start',
doesn't seem to do anything. I understand that this should re-run the
init.d script with the 'start' option, and therefore I should see one of
the two echoed messages in my log file, but I see neither, and there's
no new Squeezelite process afterwards.
For reference, here's the bit of the init.d script that does the 'force'
restart:
Code:
force)
# Force should only be used for testing purposes.
echo "Forcing a restart of $PNAME..."
if [ -f $PIDFILE ]; then
sudo kill `cat $PIDFILE`
sudo rm -f $PIDFILE
fi
sudo ps | grep squeezelite | grep -v grep | awk '{print $1}' |
xargs kill -9
sleep 1
$0 start
;;
I see the 'Forcing...' message echoed in my log file, the PIDFILE
disappears, and the squeezelite process is killed. But there's no
evidence that '$0 start' is even being triggered.
And for reference, here's the 'start' part of the init.d script - I
should at least get one of the two echoed messages in the log file.
Code:
start)
if [ -f $PIDFILE ]; then
echo "$PNAME already running."
exit 1
fi
echo "Starting $DESC: $PNAME..."
start-stop-daemon --start --quiet -b -m -p $PIDFILE --exec
$DAEMON -- -n "$NAME" $OUTPUT $ALSA_PARAMS $BUFFER_SIZE $_CODEC $XCODEC
$PRIORITY $MAX_RATE $UPSAMPLE $MAC_ADDRESS $SERVER_IP $LOGLEVEL $DSDOUT $VIS
$CLOSEOUT $UNMUTE $ALSAVOLUME $LIRC $POWER_GPIO $POWER_SCRIPT $OTHER
;;
I think it's time for me to sleep on this and look at it again with a
fresh pair of eyes tomorrow.

Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
Maybejust maybe Way back somewhere I mentioned using the "force" option instead of the "stop" option during testing. I found when you are testing things manually, you do things like forget to use "sudo" or use kill, and you end up with the squeezelite process and the pid file out of sync. I think its a permission thing, running things as tc or root, AND an orphan pid file issue. I added the force "option" (with sudo) as a brute force stop and tidyup. When a user is only using pCP interfaces everything is kept in sync and everyone one is happy. Also, as pCP is mainly in RAM a reboot means any orphan pid files are effectively removed. This can add to the confusion when testing. The reason for all this is: I like to use "start-stop-daemon" and pid files. Of course this is only in reference to pCP other distribution do things differently.

Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
That confirms that the start-stop-daemon isn't stopping the process. The fact that the process hasn't stopped may or may not be enough to prevent the subsequent start, but since the same start-stop-daemon is used to start the process, it may well be failing to do that too. I'm not sure yet what can be done about this, but we're chipping away at the problem :-) 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

Thanks - that all looks fine, and the log file shows that the init.d
script has been asked to stop the process, and then its status report
confirms that it thinks the process has stopped.
What I can see in the init.d script is that the status check will only
return 'Squeezelite is running. PID=x' if there's a process ID
stored in /var/run/squeezelite.pid AND there's a currently running
squeezelite process with the same process ID. Otherwise it will return
'Squeezelite not running.' So for pCP to report that it's not running,
but for it to continue to work in LMS, I can only conclude that the stop
command has deleted /var/run/squeezelite.pid but didn't actually kill
the process. The bit of the init.d script that handles this is:
Code:
stop)
if [ ! -f $PIDFILE ]; then
echo "$PNAME is not running."
exit 1
fi
echo "Stopping $DESC: $PNAME..."
start-stop-daemon --stop --quiet -p $PIDFILE
sudo rm -f $PIDFILE
;;
So there's an opportunity in there for an inconsistency to appear: the
$PIDFILE will be deleted immediately after the start-stop-daemon is
asked to stop the process, without checking that the process was
actually stopped. Is it possible that the start-stop-daemon isn't
actually succeeding in stopping the process for some reason?

Re: [SlimDevices: Unix] 5" Touchscreen display that works with Jivelite right out of the box.
Here is a build I just finished using the 3.5" Osoyoo display. I used a 2U "Galaxy" chassis from the 'DIY Audio Store' (https://diyaudiostore.com/collections/galaxy/products/2u-w-steel-covers?variant=12174833028) and had them custom CNC the front panel. This photo shows the display mounted to the back of the panel in a recessed cavity and held in place by 4 plastic clips. Also, a rotary encoder which I set up to allow navigation of the piCorePlayer display. Details of that are in 'this post' (https://forums.slimdevices.com/showthread.php?107001-ANNOUNCE-SqueezeButtonPi-Tool-to-use-buttons-and-rotary-encoders-on-a-RPi&p=1010055&viewfull=1#post1010055). 33672 Here is the interior. The Pi is on the left and the 5 Volt linear power supply board (which I had leftover from another project) is next to it. I am using a 'Khadas Tone 1 USB DAC' (https://www.khadas.com/tone1). I had to replace the short Osoyoo cable with a longer one, which I got from Amazon - make sure you get a type A flat cable (the Raspberry Pi version is type B and won't work with the Osoyoo). 33673 Here is the back of the unit. I am also using a USB Wifi dongle and an RF remote. 33674 And here is the front of the completed project. The only thing left to do is to figure out how to adjust the backlight, which is a little too bright. The standard piCorePlayer adjustment does not work since it does not recognize the Osoyoo as an official Raspberry Pi display. Osoyoo has a suggestion in their user manual, but that does not work on the piCorePlayer distro. 33675 +---+ |Filename: IMG_1094.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=33675| +---+ wtnh's Profile: http://forums.slimdevices.com/member.php?userid=36993 View this thread: http://forums.slimdevices.com/showthread.php?t=113708 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Material will be getting its info from LMS - but pCP web interface possibly doing its own local check ... perhaps checking for pid file. You could edit the init.d script to put some tracing in it.

Here's my adjusted script. The stop part is in there as far I can see.
I've (hopefully) just changed the 2 local bits near the beginning, and
the sudo line just now.

Starting from a fresh reboot, dac on, working sqlite etc, then dac off,

You're right - it does appear as though the stop command isn't working now. What does the M6.log file show?

Re: [SlimDevices: Unix] Start/restart squeezelite when plug-in USB dac
That's made a lot of difference! It seems to have the same effect as using --nostop. But I'd have to do all the same procedures in --nostop to check. Starting with Dac on - sqlite showing working in pcp web and default /material / apps Dac off - now shows Not running in pcp web, BUT now shows working in default /material, I can still operate the sqlite player from jivelite or material, I can switch it on and off and jivelite display reacts as expected. Other players that are synced to the sqlite player that is still on now pause ever minute or so like when using --nostop. If I soft off the sqlite the pausing seems to go away. Dac On - Music starts so it's running - pcp continues to show not running - default shows it's running and connected. This may be of interest - after the above now that pcp web shows not running but it is, if I click restart squeezlite from pcp web main page I get this - Restarting Squeezelite [ INFO ] Squeezelite is not running.

When you power off the DAC it disappears from Material, yet it's apparently still running: ps is still showing it has a PID of 6066 and the pCP web interface says it's running. So I would start to doubt that the 'stop' function of the script is working, except that it disappears from Material. I wonder how that can be the case - how can 'sudo /usr/local/etc/init.d/squeezelite status' report that it's running, but Material doesn't see it? Maybe this is the key to what's going on. When it disappears from Material, are you able to select the player and play something on it in the default LMS interface? Of has it gone from the default interface too?

Ah, wait I've just noticed that the 'stop' section of the script is not using 'sudo' to issue the stop command. I don't believe this makes a practical difference - I see an 'Operation not permitted', but it kills Squeezelite nonetheless. But it might be worth seeing if this fixes things in your case. At line 138 in the original script (probably 139 in yours after adding the 'local' declaration), change this line: Code: result=$(/usr/local/etc/init.d/squeezelite stop) to this: Code: result="$(sudo /usr/local/etc/init.d/squeezelite stop)" 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

Hi Paul - good to have another pair of eyes on this. No, I don't believe there's anything different. I think udev calls the script as root, but the crucial line that seems to be acting differently between the scenarios is 'sudo'ed anyway.

What the above shows is that the very same script, the one that is failing to start Squeezelite after 5 attempts when triggered by the udev rule, works when called manually from the command line. i.e.: The udev rule calls the script at 331.27 seconds in: Code: [ 331.27] Script parameters: restart M6 1-1.2 This apparently failed to start Squeezelite 5 times. The manual script call was at 356.94 seconds in: Code: [ 356.94] Script parameters: restart M6 1-1.2 This evidently managed to start Squeezelite at the first attempt. And it's not even the script itself that is failing - it's being triggered with the right parameters, the built-in restart command is being called correctly and is attempting to start Squeezelite, but seems to fail to work in the former case: Code: sudo /usr/local/etc/init.d/squeezelite restart I can see no reason for this, and what's doubly confusing is that I don't see this behaviour with either of the USB DAC setups that I have here, yet you clearly have a very standard setup. I will have to think carefully about how to isolate the problem. Since I can't recreate the problem, the only way I can think to tackle it is to ask you to do some experimenting: At the point where you called the script manually, could you try some different steps. So, from the top: 1) Re-run the 'install' option but without the --nostop option. This should recreate the rules file with both options. Reboot. 2) Disconnect the DAC. This should kill the Squeezelite process. Code: ps | grep squeezelite sudo /usr/local/etc/init.d/squeezelite status 3) Reconnect the DAC. The expected behaviour would be for Squeezelite to restart, but we know that in your case this is not working - it fails after 5 attempts. At this point, instead of issuing the restart command manually from the command line, let's see what's going on: Code: ps | grep squeezelite sudo /usr/local/etc/init.d/squeezelite status 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
