I don't think so. I just used Cool Edit 96 to record a few
seconds of my voice and play it back. This uses the same
drivers as does Ekiga - but Cool Edit records and replays
fine. I set Cool Edit to record in 8 bit mono at 8000 Hz.
It has to be something about the way Ekiga uses the drivers,
doesn't it?
