[Solved]Alsa/pulseaudio going mute

nomorewindows · 2014-06-06 22:36:48

Logging out/in with awesome/slim seems to have audio at first, but after awhile ssems to switch to pulseaudio, but then pulseaudio fails to recognize audio hardware as anything but dummy output.

Seems to be related to FireFox.

fuser -v /dev/snd/*

I can switch to a virtual console/getty and try to play sound during a mute-out and it won't play there either. When I logout and back in to the WM it restores functionality, but something in firefox seems to trigger something with audio configuration that disables it from playing sound even with the mixer settings turned all up and unmuted. The only thing that works during mute-out is beep.

That would be probably flash. What if you kill plugin-container?

fuser -v /dev/snd/*
pkill -9 plugin-container

/dev/snd/timer:      <user>       xxxx f.... plugin-containe

Looks like to me that plugin-container is the problem.

It goes away with exiting firefox and nothing shows up with

 fuser -v /dev/snd/*

when the failure occurs. No applications with sound work, and fuser doesn't show anything.

If you use PA. how come flash grabs your hardware? You probably have pulseaudio set to suspend when idle. You might want to change that:

$ cat ~/.config/pulse/default.pa
[...]
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
[...]

Can you change the samplerate in alsamixer?

pkill -9 plugin-container

Causes flash to crash, and restores audio. I run flash in dwb-git just fine (unless flash craps it out).
I have no ~/.config/pulse/default.pa, I have only one file name 'cookie' in that dir. I do have /etc/pulse/default.pa and it is uncommented. Will try to fix that, and maybe what the audio pops when I switch to battery.

I have no such option in alsamixer.

Commented out in /etc/pulse/default.pa the line

load-module module-suspend-on-idle

and we now have sound in Firefox/flash.
Never had any problem with it before except maybe the possibility of running on battery.
