This is a quite complicated option but it is possible to use alsa to
capture stuff to file. At least I think so. Some links I found:
Presumably by writing the right asoundrc wherein you use the file
plugin you should be able to redirect the streams to files. Using a
soundserver might make this a bit easier but this is one way at least.
