Debian Hardware :: Audio - Random Loss Of Sound

I'm having problems keeping audio working. Using Sparky with 3.16.0-4 kernel on a homebuilt PC. AMD A10-7850K CPU on a Gigabyte F2A88FN-WIFI mobo.

I'm using a set of Logitech Z-5 USB speakers and I repeatedly lose all audio output. To get it back I need to do 1 or all of these steps:

1) Unplug the speakers
2) Kill all processes that may be producing audio (Chrome beta, IceWeasel, Exaile, etc.)
3) Start Alsamixer and select another source in sound card list then reselect USB card #2.
4) The weird one - Remove and then re-add the volume applet that I like to have in the panel. When I lose sound th slider gets "stuck" and will not move. It will not recover.

I may need to repeat this several times but it will come back. Not immediately after any step but after a few attempts it just begins working as long as nothing is trying to produce audio at the moment. Sometimes Alsamixer says that my USB Card has no controls when I reselect it, not every time though.

Most of the time if I have more than 1 source open at any time it is likely to die again, for instance I like to stream Google Play Music. If I pause that but leave it open, then try to watch a Youtube video or other source I will either get no audio from either source, or lose the streaming audio source when I try to restart it. Going through the above routine 1 or more times usually restores it.

I have created asoundrc.conf file to tell system to use USB audio as described here -> [URL] ..... In my case USB is # 3 in the list. So this is my file:

Code: Select allpcm.!default {
type hw
card 2
}
ctl.!default {
type hw
card 2
