Audio problem on G62-B70SP

[Bruno Martins <bmomartins@gmail.com>]

Hello everyone,

I am running Debian Squeeze on the following notebook:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02511383&tmp_task=prodinfoCategory&cc=us&dlc=en&lc=en&product=4315442

I can hear no sound from the speakers, but it plays well if I plug in 
any headphones on it. Still, no sound on the speakers.

Some command-line information about the system and the sound card can be 
found here:

Have anyone experienced this before?

Thanks for your time.

Best regards,

Bruno Martins
