As a general question, has anyone ever managed to get more than 2 
channels out of any oss driver.
I.E. Select 4 channel output in xine, and the correct 4 channels come 
out of 4 speakers.
If no-one can get 4 and 5.1 channel working with oss drivers, maybe we 
should prevent the user from using them, when used with oss.
I don't use oss, so I cannot test.
