I have a Compaq Presario CQ-212US Notebook PC. I'm trying Xubuntu 13.04 64-bit on it. So far, so good (my wifi actually works, which is a totally awesome improvement), except that my microphone isn't functional.

The volume is turned up on the microphone. I can adjust the volume, but when I try recording with Audacity, it doesn't record any sound.

I tried opening Alsamixer from the command-line and turning up all the microphone stuff (microphone boost, capture, etc.) there (which wasn't turned up), but that didn't do anything, either. I tried selecting Pulse Audio in Audacity, but that didn't work, either.

The microphone was similarly dysfunctional in every other edition of Xubuntu that I recall, and most versions (not all) of Ubuntu.

However, it's entirely functional in the current stable version of Debian (using Gnome and GTK 2).

Any ideas?

If I type
lspci | grep -i audio
I get
Audio device: NVIDIA Corporation MCP72XE/MCP72P/MCP78U/MCP78S High Definition Audio (rev a1)

Regular audio works fine.
