|Hi aptosid community,
I have a strange problem with my Gigabyte GA-880Ga-UD3H or, to be more specific, with the Realtek ALC sound chip. As the title of my post suggests: I have no sound, not a single tone.
head -n 1 /proc/asound/card0/codec*
Codec: Realtek ALC892
The chip is recognized correctly
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xfe024000 irq 16
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xfdefc000 irq 19

Of course all volume controls are at 100% and no muting is switched on.
AFAIK this chip should work ootb with Kernel 2.6.38
I tried all the hints on the Ubuntuusers.de wiki (german) without success. I really do not know what else I could do. A google search did not help much
The only thing I did not try was the "original" Realtek drivers. But I'd like to avoid this ...
I hope there is anyone who can give a hint how to solve this problem since it is very annoying to have no sound.
Thank you in advance
