Mmm, I could try these things, but I'm uncertain. The box is dedicated
solely to audio recording, no other task will be running on it. Is there
any way to measure buffer _overruns_?
Buffer underruns are no problems and are in fact desired in my
situation, but not yours. Cdrecord and the cdrw will handle these
correctly (they are selected to support that). I think underruns are
indeed a problem with playing.

I believe I already did this. The buffer is a few MB and I cannot fill
it even in 30 seconds. This was mostly needed to compensate for
cdrecords buildin delay and for it to start writing to CD.
Anyways Thanks for the suggestion...
