exactly the same problem with my brother's dial-up.
my guess is, that the cdrom driver has some ugly kernel lock, which blocks
everything else while data is read from the cdrom.
the problem can be worked around by letting cdparanoia read data in
small chunks. i achived this by piping it's output through a named pipe
directly into an mp3 encoder (anybody wants my script?).
if you want only ripping, then something like this might be a workaround:
(this is untested!)
dev=/dev/cdrom #adjust!
for trk in `list_audio_tracks -D "$dev"|cut -f1`; do
cdparanoina -q -d $dev $trk - | while dd count=128; do sleep 1; done >$i.wav
done
adjust the count= to something reasonable (i have no verified value; the 128
gives 64k, which is the buffer size of a pipe (afaik)).
note, that this will be slooow, but should not interfere with the modem
_too_ much.
