Can anyone get the surround sound to work with the add-on card? I've plugged in my front speakers to line-out, my rear to the one marked Rear on the CA-20 (I believe that is what the audio card is called), and I've got my Sigma Realmagic Hollywood Plus audio plugged into the line-in. With the Sound Mixer thing for the audio, when I do 4-speakers, it changed the line-in to Rear-out I believe, but when I do speaker test, it does the proper sound out of each speaker, however, Winamp, and other audio things (like games) won't have ANY sound out of the rear speakers. It's REALLY pissing me off, as the board advertised 5.1 support, and it won't even freaking do 4 correctly, and I've got no money to spend now on a sound card.
