It's because the input "PCM" switch interacts with the "Line in"
switch. When I mute "Line in" there is no sound, but when I mute "PCM"
only, the sound will be delayed coming from "Line in". I fixed it with
-delay 0.5, but then my channel switching is a bit rusty.. I(I switch
channels with my video recorder).

It didn't improve my results. I think it is something with the
immediatemode=0 (which is default "0" when using mencoder). It would
be nice, if I could capture the sound directly from the line in
device, bypassing all the fancy switches... (and still get video and
audio the same length...Hmmm.. )

Hmm okay, I have Creative Audigy running on Ubuntu linux distribution.

Thank's for the input.
