I have an application that is running a capture and playback
simultaneously, with a fixed latency between them. In case of an
underrun on the playback channel, I'd like the driver to keep running,
without a short gap in the sound, but without losing synchronization
between catpure and playback (i.e., keeping the same latency).

Can anyone suggest a way to do this? If the playback channel just stops,
there seems to be no way to resynchronize the playback and capture
without restarting the capture, which would result in lost samples.
Is it possible to prevent the playback from stopping on an underrun?

        Thanks for any help -- Ken McMillan
