Dell Studio - 1558 ALSA sound problem ubuntu9.4 fix

I had the problem and the Laptop, Dell Studio 1558:
just exec as root: "nano /etc/modprobe.d/alsa-base.conf"

and add this line:
options snd-hda-intel model=dell-m6

it works for me. modeprobe.conf files are empty.



if modprob.conf files are not empty then add this line to
options snd-hda-intel model=dell-m6
it will work
