Icecast: I found some source clients that will convert FLAC to lossy
formats like MP3 or Ogg Vorbis, but no clients that would feed FLAC
streams to Icecast. And while it looks like the 'flac' command line app
can output FLAC inside Ogg containers, I haven't found how to feed that
to Icecast (to say nothing of whether SB2/SB3 can play Ogg FLAC in
addition to native FLAC). IceS says its playlist input plugin is for
Ogg Vorbis, but perhaps I could use a named pipe to have it stream Ogg
FLAC to Icecast from flac (sox + flac?) -- I haven't tried that. 

My sound card is a 7 year old Creative Ensoniq PCI card. I'm using an
old version of Fedora Core -- old enough that I had to build new
alsa-lib and alsa-utils packages to get past a "left channel only"
capture bug in ALSA. Not being able to use ALSA is disappointing. I had
hoped to have two streams: one from the stereo tape-out and one that
would play whatever was coming out of the motherboard's sound card (so
I could simulcast TV/DVD audio without having to route sound through my
stereo receiver). I got the alsa plugin working with IceS with the
motherboard line out sound, but it was terribly noisy. I got much
better sound from the PCI card's line in, despite the PCI route
involving additional D/A and A/D and passing through three patch cables
and two external analog devices (TV, receiver). Some of my trouble was
likely level/gain noise issues, but after my OSS/sampling tests with
the PCI card, I bailed on the notion of using ALSA.

I might replace the sound card if I were confident that the new audio
in would be good enough to archive old analog recordings, as that CD-RW
deck certainly isn't very convenient.
