After a certain time playing music or sitting idle (usually a few hours ~ 6 ) squeezelite stops outputting, although still responds to commands #52

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1.I start squeezelite with the following command 
   squeezelite-armv6hf  -o sysdefault:CARD=Audio -d all=debug -f var/log/squeezeslite.log

2. Either I play a long file (my test file is a 12 hour file of white noise) or 
play nothing and all squeezelite to idle

It usually takes about 6 hours either way

What is the expected output? What do you see instead?

I expect music to play - squeezelite is responsive to commands, switching 
songs, etc and appears on the remote app I am using to be playing but no sound 
comes out.

What version of the product are you using? On what operating system?

I am using 1.3 binary (squeezelite-armv6hf)
on a Raspberry Pi model B, latest distro of raspbian ( 3.10.19+ #600 )
Using a fio 10 audio DAC 

output of squeezelite-armv6hf -l

I have looked in the log file and when a file is playing it will stop when this 
occurs in the logs

Yes looks like there is a bug here.  Will look at for next version.

I, too am seeing this identical problem, with a Behringer UCA-202 DAC, so my 
device string is sysdefault:CARD=CODEC

To the original poster - have you tried rpi-update?  I was having a similar 
problem and updating the Pi's firmware has eliminated the issue.

Please try the 1.4 beta version as this should change how this is handled.

GoogleCodeExporter commented 8 years ago
I suspect this is the same issue as #31 & #48. Maybe merge them? 

I am seeing the same behaviour on 1.4. You either just get silence or the odd 
pop. A restart of squeezelite solves the problem. 

I can post more logs if you like.

Some comments on the log:
Last night at 21:52:57.118329 the last track ended.
This morning at 06:45:37.552011 I started playback. Again just silence with the 
odd pop.
At 06:46:23.740098 I restarted squeezelite and playback resumed without any 
further intervention.

Full log is attached.

Can't see anything specific in that log.  Could you try with -d output=sdebug 
to see if there's anything strange there (you will get lots more output)

This does seem to be specific to the Pi though?

I will change the logging tonight and see what it looks like in the morning.

I will also fire up a client on my Windows machine at the same time so we can 
see if it's only a Pi thing.

Experiment all setup and of course this morning it all just works. Both the Pi 
and Windows machine play. The one thing I did change was selecting an album 
encoded in FLAC because I recall you mentioning somewhere that libmad may have 
issues. So I will repeat this test again with an MP3 encoded album.

Original comment by morkh...@gmail.com on 9 Jan 2014 at 4:37

GoogleCodeExporter commented 8 years ago
If it turns out to be libmad then try mpg123 as an mp3 codec - there are some 
arm builds on libmad which cased segfaults, but I am not aware of ones which 
stop working after a while...

As Murphy would have it I haven't been able to reproduce this with sdebug on. 
I'll carry on testing till I get it to fail again and report back.

I have a bit of a strange problem. When I run squeezelite with sdebug on I 
can't reproduce the problem. As soon as I go back to all=debug the problem 
comes back again. It's almost as if sdebug is keeping squeezelite "alive". 
Possible fix except for the log size problem ;)

So I changed tactics and decided to give mpg123 a go, but I'm struggling with 
rates which mpg seems to be very fussy about. My USB card does up to 48000.

With mad set, playback works and I see this in the logs:

I've had a go at setting rates with -r, but either there is some other issue or 
my syntax is incorrect as my alsa breaks and I have to reboot before aplay -l 
and squeezelite -l will show any cards again.

Only output I get is:
# squeezelite -l
Bus error

Can you shown what all parameters are you are starting with?

This is what is working with mad
-n Study -o hw:CARD=Device -c mad,flac -d all=debug -f /var/log/squeezelite.log 
-p 2 -a 100:4 192.168.1.11

I tried: 
-n Study -o hw:CARD=Device -r 44100 -c mad,flac -d all=debug -f 
/var/log/squeezelite.log -p 2 -a 100:4 192.168.1.11
Which breaks alsa

note you need -s before the ip address with recent versions.  If you set -r 
44100 and the material is not 44100 then you will have a problem - what are you 
playing?

Thanks will amend my flags to include the -s

Just playing bog standard CD rips either in "decent" quality mp3 or FLAC. The 
material certainly is 44100.

I ended with a FLAC album last night and this morning it played again with no 
intervention. I'm going to stick with FLAC and the all=debug for the next few 
days and will report back. If that works consistently I'll go back to battling 
with mpg123. I did come across this detailed article late last night which 
looks like it might solve my sampling issues, but it was a bit much for my 
tired brain at that point :p

I've been sticking to just FLAC for the last few days and so far no issues. So 
it would seem to me there is an issue with Pi, Squeezelite and mad. Triode are 
you able to reproduce this?

Will see if I have some time over the weekend to have another go at mpg123.

squeezelite uses libmad or libmpg123 - so you will libmpg123 rather than lame 
to get the alternative codec
