Hi,
when using this kernel, I hear no sound using the speakers, only using the headphones, plugged in at the front.
With 2.6.38 (dmesg attached), the speakers get fed, too.

Takashi, this looks like a regression in control parsing in the realtek codec. The kernel logs are at http://bugs.debian.org/631963 but I don't think they'll tell you much.
I'd definitely need alsa-info.sh outputs on both working and non-working kernels, i.e. on 2.6.38 and 3.0-rc4.
Toni, can you provide the output of 'amixer -c 0 controls' under 2.6.38 and 3.0-rc4?
alsa-info.sh outputs contain already these. Toni, could you give alsa-info.sh outputs of the above kernels?
thanks,
Takashi
