[pulseaudio-discuss] Emptying a record stream's buffer

I'm trying to take a record stream which has been recording for some
time, and empty its buffer. I'm especially interested in causing the
return value from pa_stream_readable_size() to become 0.

I've attached a test program here which uses pa_stream_flush(). The
documentation for pa_stream_flush() says, "This discards any audio in
the buffer," but it doesn't actually seem to work for record streams.

Any hints?
