I can get all of my speakers to work, but one. The one that does not work is the front right channel and that happens to be the one that relays the cables from the back of the PC to the sub. The x-530's are 5.1 and my sound card does support it. It is an onboard karajan audio card. It uses realtek ac'97 drivers. I've checked checked a lot of settings on both the audio driver program and windows audio and I can't seem to fix it. I've also tried switching the cables around and where they are plugged and it does not help. Any help would be appreciated.
