After becoming terminally annoyed with a my broken Intrepid installation, I decided to install Jaunty.
While I was enjoying the new growl-esque notification system, I noticed a flaw – no program would make any. Not a peep.
Headphones plugged in, check. Volume sliders in gnome-sound-properties all the way up, check. Hmm… Restart. Same. Uh… Reinstall. Nope.
So I tried everything Google could throw at the problem, to no avail.
After a day of mashing my fingers on the keyboard I gave up and resigned myself to code in silence.
It took me an hour to start searching for a solution – I found this thread: after Jaunty upgrade, no sound exept from OSS. There was no solution there, but happy to have found other to share my plight, I posted.
Post #9 was my solution.
For some reason “Independ” was turned “ON” in alsamixer. Switching this to “OFF” resulted in sound. WTF? I don’t know either. Nor do I care, as I now have sound.
Included is a screenshot of the section of alsamixer that needed punching:
To see the relevant option in a normal sized Terminal window I had to press right a few times.
