I have a quadraphonic speaker setup but i have two of the speakers in a different room, with XP and itunes the sound would output to all 4 speakers, since upgrading to vista ive been unable to get it to do this. The quadraphonic works on test mode and for surround sound. Any ideas or advice would be amazing.<br><br>Cheers!<br><br>BarryMon, 02 Apr 2007 02:04:29 GMTBazcraig
