i'm afraid i don't even see a "Wave" item.
i'm using gnome-mixer and alsamixer-gui.
i am using "Line" for the input, but i also seem to
need something called "ADC" selected for any capture
to happen at all. but it always sounds horrendous.
i don't know if all this is a separate issue from the
latency issue or not.
thanks
