Gazelle Professional, less than a month old (woot :-) has been working quite nicely until after a recent reboot I lost sound.
After fiddling with it for a bit, and following these instructions, https://help.ubuntu.com/community/So...otingProcedure , I discovered that the culprit was the 2.6.35-28 kernel upgrade. Downgrading back to 2.6.35-22-generic restored audio.
I have attached full outputs from alsa-info.sh for both kernel versions.
I'll be honest, I'm not 100% what is meant in the Gazelle page by "Audio Output: THX TruStudio PRO", but whatever it is, the delta between -22 and -28 seems to not sit well with it (or some combination of it and various ALSA utilities).
Also, looking at these outputs, it seems to be picking up two sound chipsets... could it be that somewhere along the line it's getting confused and using the wrong one?
