squeezelite failing on Raspberry Pi with Slowed, Crackling Audio #28

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have been running squeezelite on the raspberry pi for a while now (Arch 
Linux).  After a recent system update, I started to get bad crackling and 
slowing of the audio.  Log output shows a bunch of these:
[13:38:16.253615] output_thread:594 XRUN
[13:38:16.253965] ALSA snd_pcm_hw_start:590 SNDRV_PCM_IOCTL_START failed (-32)

I run squeezelite with the following line:
squeezelite-armv6 -m b8:27:eb:cb:b2:80 -n "Kitchen Player" -d all=debug -f 
squeezelite.log

So I do not specify a particular audio device.

I've gotten this both with squeezelite compile from the latest source, and from 
the pre-built binary from this site.

Any ideas?

George

try increasing the alsa buffer size, add "-a 80" to the command line - does 
this help?

I just ssh'd in from the office and ran the same line above but adding -a 80.  
I'm not there to hear what the output sounds like, but the log is now clear of 
the error messages.  I'll take a listen when I get home and let you know if the 
sound quality has not changed.

Thanks,

George

It looks like that did it.  I'm not sure what has changed that required a 
larger buffer, but I'll poke around the recent updates to ArchLinux to see if I 
can discover anything.

I'm seeing the same on rasbian, also after an update. Not getting anything in 
the debug log though, I only have debugging turned on for output, stream and 
decode. I'm getting a few audio errors in syslog. The -a fix seems to be 
working for me as well.

Same thing on Raspian after an update. -a 80 still gave some short pauses, -a 
160 seems to have fixed it.

closing as resolved by buffer tuning
