I just noticed a very strange thing:
After my sound dissapeared again a few hours ago, I started looking for
ways to get it back without a reboot and this is what I ran into:
==========================
localhost# sysctl hw.snd
hw.snd.targetirqrate: 32
hw.snd.report_soft_formats: 1
hw.snd.verbose: 1
hw.snd.unit: 0
hw.snd.maxautovchans: 4
hw.snd.pcm0.buffersize: 4096
hw.snd.pcm0.vchans: 1
==========================
After doing this:
==========================
localhost# sysctl hw.snd.pcm0.vchans=4
hw.snd.pcm0.vchans: 1 -> 4
==========================
The sound seems to work in all apps again. Is it possible that something
"bumps down" the value of hw.snd.pcm0.vchans causing problems at the
same time ?
