I'm sorry to dredge this topic up, since I know it's been talked about before, but I've been searching Google for hours and I haven't had any luck yet.
I installed Ubuntu on my brand-new, fresh out of the box HP Pavilion dv4-1225dx laptop today. I ran Windows first to make sure everything worked (including the internal speakers), but I didn't partition my computer when I switched to Ubuntu - I just took Microsoft completely off.
Anyway, I can't get sound to play out of my internal speakers. My headphone jack works fine, though. I tried to follow the troubleshooting guide (https://help.ubuntu.com/community/SoundTroubleshooting) but I got lost at the "is your sound card supported?" part. I couldn't find my soundcard on the list, but then again I'm not sure what I'm looking for.
Here's what the computer said my soundcard was when I did the lspci thing:
Then the troubleshoot guide started talking about manually installing the drivers, but I don't know how to find out what the driver is. I think my sound card has to be supported - after all, I do get sound out of the headphones - but I really am not very familiar enough with the inner workings of computers to know what's really going on.00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia

(ps - the sound doesn't work for anything from the internal speakers - no startup sounds, no beeps, no music)
Thank you so much for helping me out! I know this is such a newbie problem, but I really do appreciate your time!
