Using pipes to capture stdout/stderr is a bit of a pain on Windows. So currently
we ignore any output from polypaudio. To ease debugging it would be nice to see
what is going on though, so we should try to use polypaudio's ability to log to
Continuation of 2820. PA logs to stderr, but apparently, stderr is buffered on Windows. A fflush() in it's log.c should probably fix this.
You can also turn off buffering. We have a hack in OpenSSH that does this.
This was fixed by upstream when we upgraded to 2.1.
