[silverblade] 34478: Partially implemented wave output reset (WODM_RESET) which sends a request to the device to stop playing and (for now) drops the current buffer, which stops the streaming mechanism from doing anything further. This will need to be done more cleanly later. Think I've also fixed the bug where it was crashing on exit.

Log:
Partially implemented wave output reset (WODM_RESET) which sends a request to
the device to stop playing and (for now) drops the current buffer, which stops
the streaming mechanism from doing anything further. This will need to be done
more cleanly later. Think I've also fixed the bug where it was crashing on
exit.
