Sorry to go off-topic, but there are lots of cards that don't have Master control. Would this qualify as a bug?

The OSS4-provided master mixer control is actually relative to EMU20K1 port volume settings. So, it should be named PCM. The Master mixer control will be shortly readded as a control which sets the master volume.

I postpone this until you send the Master control addition. Most apps requires Master control rather than PCM control, AFAIK.
