An interesting point.  Do any of the other audio types actually have a 
mixer which is seperate from the audio device?  Perhaps we should simply 
disable that combo unless it's an OSS device?

I need to check the code for Alsa since that's the main exception I can 
think of?  I wonder whether it would be useful to allow the option to 
select an OSS volume control device, eg if the user wants an ARTS (etc) 
output device (etc)?
