Summary: processed sound

Initial Comment:
I have an SBLive card and I am looking for a way to get
the sound from the tv piped to it in such a way that
alsa can handle it. now it is handled by the card
itself which means that only the small the center
speaker is used.

currently I do recording in one window with ffmpegrec
and play the file in another window.

It would be a pain for tvtime to process the audio as well,
not just in terms of the code involved, but in tracking the
audio latency and sync.  Appliactions like MythTV which
actually record the video have it easy, since they have a
lot of control of the output rate and can keep sync that
way.  Right now in tvtime we process video in realtime as
fast as it comes in.  We would have to write some sort of
synchronization infrastructure probably, or at least some
way of managing the buffer sizes.  Ugh.

If someone wants to work on this I would be OK with it, but
I wouldn't want to do it myself or consider it a requirement
for tvtime 1.0.

arecord -f cd would do it, but I would prefer a solution
where all is in 1 program. programs like mytv and etv do it
but myth is a nono when you are not in the states and etv
for some reason does not want to record sound at all.

When I saw that tvtime did processing of the video (like
interlacing and such) I was hoping it would process the
sound too.

% arecord -f cd | aplay
should do it.
If you want to send it via spdif you can try 
% arecord -f dat -t raw | ac3dec -R
which segfaults here, though.

Shouldn't this be an option somehow in the driver for how to
handle anything on the line-in going out to your 5.1 system?
