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:

 http://bugs.launchpad.net/bugs/1013183

After reverting the referred commit, everything seems to be working
fine again.

Any ideas/fixes?

Cheers,
--
