So I have a Revo. And it does DD/DTS passthrough nicely. I need to be able to listen to MP3s though through the digital connection. I've tried ASIO (doesn't play anything) and Kernel Streaming (crashes my computer). How do I get this thing to work? I have a USB SB MP3+ card that I just plug in and it outputs everything through the digital connection...I expected the M-Audio to be just as simple. Seems I was wrong. Does it not pass everything through the digital output?
