For some reason, I’ve discovered that as soon as you start a render in Blender or Cycles, the sound system stops working instantly. I can’t get any audio to play, and I have to log out and back in.
Ubuntu 11.10
check your default sound settings in blender
-> user-config
there are different options: alsa, sdl, openal, etc.
some may work better or … worse.
If the default is set to “openal” then this is a sign
your openal-system-settings are not in sync to work with this.
You may disable sound (= set it to “none”) or choose sdl (this
should work for nearly all linux-distributions since …
yep … since a lot of years, since sdl was setup working with alsa.
…
and last: there are even gui-tools to check the programs using the sound-devices,
in older ubuntu-versions, there was an pulse-applet to check the mixing of different sound-output from different programs.

Uh, how do I do that?
And also, I nailed down the cause, and it is Blender. Also, it seems to only affect web browsers playing web videos and such. Local files play sound fine. Blender’s open, but not rendering, and I can listen to colbertnation.com videos. Hit the render button, refresh, and Stephen goes silent. Maybe it’s a bug with Blender.
