I believe it has something to do with the way the card is detected. I've been trying to get this working for a while now. The only thing i've found is switching to the 2.6.32 kernel solves it in any distro. In arch I tried downgrading alsa to 1.0.22 and still no sound but it works fine with 2.6.32 and alsa 1.0.23. I think the problem is in the snd-hda-intel driver not alsa. From my understanding the driver is built in to the kernel now?

Other interesting things i've found is that alsamixer reports a different chip in 10.10 vs. 10.04.

10.10 Card: HDA Intel Chip: Intel Cantiga HDMI (Sound doesn't work)
10.04 Card: HDA Intel Chip: Intel G45 ... (Sound works)

On my acer aspire 7736z i've tried passing all kinds of model settings in /etc/modprobe.d/alsa-base.conf with no success

Qusai Abu Hilal you can find alsa-base.conf in /etc/modprobe.d/alsa-base.conf
