	Hello,

	I was able to get sound from Composite1 by adding the following fields to the 
composite entry in cx88-cards:

                        .gpio0  = 0x04fb,
                        .gpio1  = 0x10ff,
                        .gpio2  = 0x0ff,
                        .audioroute = 1,

	The gpio values were fetched under windows using regspy. I didn't have enough 
time to test with audioroute=1 only, which may have been enough to get sound 
working.

Regards,
	Stef
