I have just bought the above sound card and it is recognised within Ubuntu 11.10 and produces sound using the SPDIF output to my surround reciever.
The problem is that I cannot get it to output anything more than stereo over the SPDIF. In sound settings I cannot set anything other than Digital Stereo (IEC958) Output.
The chipset is cm6206 but is recognised as a "CM106 Like" card.
How do I get 5.1 digital surround sound to work?
Since this is the output for my media centre in the lounge its important that the surround sound works. Any help greatly appreciated.
