Yes, I've tried that one more time - but I don't know if/where is a more up to date version of the kext. The only solution I have right now (apart from using only two of my 6 speakers) is to connect the front panel audio output line to the extra line in jack of my speakers volume controller - this way I can have the stereo sound split between all speakers and subwoofer. But note that it's still far away from the real 5.1 surround! I appreciate your kind help, though, really. My next question would be - what kind of sound card would be recognized by leopard driver's as a 6 channel enabled card? I mean, isn't anybody using zephyroth's, kalyway's or leo4all simply to watch a movie with surround?
