My Laptop is MSI EX620 http://www.msi.com/product/nb/EX620.html#/?div=Specification
On clean install (ubuntu 10.4 32bit...and so on older versions) I have no sound. After edit /etc/modprobe.d/alsa-base.conf and put this line
options snd-hda-intel model=targa-2ch-dig
...sounds word on both left and right speakers . But my laptop si 2.1 audio system and i can't run sounds on subwoofer. Please, give me a solution
