Public bug reported:
Hopefully all the necessary info is in the extra stuff that
automatically got sent.
Basically, I didn't do anything fancy, but audio recorded with my
microphone (through Skype, and arecord in the Terminal) has tons of
static and the voice is distorted or saturated.
Booting this computer on Windows doesn't have issues, so that's why I
don't think it's the computer, I think it's the OS.
Thanks!
