Sound not working in Ubuntu 9.04?

[Rule]

Anyone here using Ubuntu 9.04 desktop?  I installed it on my Dell Studio 15 laptop.  Everything works fine, except sound.  Any idea what the issue might be?

Tried adding
options snd-hda-intel model=dell-m6

to
/etc/modprobe.d/alsa-base.conf

and no luck.

I didn't have sound working before...but I forget how I fixed it.  Check the restricted drivers?

Rule, it sounds like you're doing stuff with ALSA.  Doesn't Ubuntu >= 8.10 use PulseAudio?

I've had problems with PulseAudio before, but it always seems like it worked after a fresh install.  Sometimes it randomly stops working, and I have to restart pulse.  Maybe you should restrict your search to things dealing with PulseAudio?  I think you can also fiddle with what sound device you're using.  If it really is ALSA, maybe try switching to PulseAudio?

I'm sure you probably have checked this, but not too long ago I installed Ubuntu on a machine and sound was muted for some reason.

Check alsamixer at the bottom of 'Master' you should see '00' highlighted, and not MM.  :P

On that same note, make sure 'speaker' isn't muted if you're on a laptop. If it is, then only headphones will work.

Thanks for the suggestions. I upgraded to 9.10, and the sound works again.
