Looks like there are many more controls now available than in 2.6.32. I've tried to enable them all, but I'm getting no sound on this Asus M4A785G HTPC board (VIA VT2020) with current linux-2.6.git.

Accidently got it to work just now. The Asus M4A785G HTPC board has 2 x phono outputs on the back (hooked up to my amplifier) that - with 2.6.33-rc2 - get disabled if there's no jack detected. I've connected my monitor's built-in speaker to the jack as a workaround.
