I'm running Ubuntu 9.04 x86_64 on a Dell Studio 14z with nvidia 180 series graphics driver. Audio did not work until I installed the nvidia graphics driver. Sound works, but I have to turn the volume all the way up before I can hear it and the quality is pretty bad. On windows, the quality was much better and the sound was much louder. I have completely removed pulseaudio (which I hate with a passion), and the problem still persists. Also the built-in mic does not work, but that's not so much an issue as the audio volume.

lspci:
nVidia Corporation MCP79 High Definition Audio (rev b1)

Could it be a problem with HDMI sound support?

Everything is unmuted and turned up to the maximum in alsamixer. I have switched everything to ALSA in the gnome sound preferences, but I get the same problem regardless of what settings I use there.
