Hi,
After commit b0791dda813c179e539b0fc1ecd3f5f30f2571e2 ("ALSA: hda/idt
- Fix power-map for speaker-pins with some HP laptops") we have
several bug reports about not having sound on HP Pavilion laptops.
Here's a link to one of these bug reports:

After reverting the referred commit, everything seems to be working fine again.
Any ideas/fixes?
Could you give alsa-info.sh output on both working and non-working kernels?
Also, does it really happen with the upstream kernels (vanilla 3.2.y and Linus tree) without ubuntu changes? If yes, I'd need alsa-info.sh outputs on these, too.
thanks,
Takashi
