After updating to ubuntu studio, lost sound.

[bart deruyter]

Hi,

what happened to me :  I had an update yesterday, did not reboot, and sound
kept working. This morning I started my computer, and I had no sound either
in pulseaudio. Pulseaudio could not find any devices. Using jack I could
have playback in music apps, like lmms and ardour, but no input.

Fix was a bit weird, but worked perfectly :

In the list of apps to start on boot, one of them is pulseaudio. The command
shown was 'start-pulsaudio-x11'. I changed it to 'pulseaudio', without the
start and x11 part. I logged out, logged in, and things worked perfectly
again.

Turns out, when pulseaudio is not running, input channels are muted, so I
could not have any input in jack.

I have no explanation for this. I do must admit I have falk-t-j's repo's to
have jackd2 in lucid. Perhaps that has something to do with it.

Grtz,
Bart
