If your audio format is PCM (uncompressed aka lossless) you can ONLY EVER get L/R coming out of an optical (or RCA/coax) SPDIF. Out of curiosity, what are you using to test the discrete channels? If you have a DVD with the THX logo it - 90% of the time - has a series of tests that lets you play one channel of audio at a time (quite handy). Working and fully functional are 2 very different things. Just because a 'working' kext makes the name pop up doesn't mean it will do the advanced features. but I'm not sure if the hardware inside is the same as it originally was (same chip, etc). (I too have the X-Fi USB old version so I'll report back later with how it worked for me in a week or two - I haven't used in OSX yet) Trying with a new board in the next week or so (the GB H77N mini-itx) so I might have some better luck. Mind you I've only spent a day playing around and installing ML. I have problems getting multi-channel audio with 10.8 to work, in 10.6.8 it worked easily for me. As such these other responses are rather speculative. I was able to answer the question of why the same procedure that worked for the person in the thread was not working for you.
