Comment 12 for bug 368629

tasmarc, what do you mean with "solved"? In fact I do have sound since May, but it is not perfect yet: the system beeps while shutting down, and the volume is too sensible to the volume bar (system nearly silent with volume up to 50%, suddensly lound over 60%), and, third, if I leave volume over 60% I continously hear a kind of bzzzzz noise from the speakers.
With "solved" you speak about similar problems, or simply about the presence of sound?
Moreover, I have the followinf line added to /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=dell
and nt:
options snd-hda-intel model=dell-m42

Which is the difference?
Anyone more skilled than me (I'm quite new in Ubuntu too) can explain?
Tnx
