Sound Cmedia CMI9761 - Surround Sound, only getting 2 channels


Hi,

I have an ASRock K7VT6 motherboard with the Audio chipset CMedia CMI9761 (6 channel) onboard.

I'm running opensuse 10.3

I can get audio out of the normal speaker out port, so just 2 channels.

However, I don't know how to go about getting 6 channel audio working?

Here is lspci:
