I was just listening to some System of a Down about 25 minutes ago, on low sound settings. Now when I just went to play Call of Duty 2 demo, the sound was completly gone. Turned volume up full, and no volume. Came out to windows to mess with the X-Fi control panel. I just turned up the volume and that. At full volume, the speakers will only give out about 34 decibels. I switched to the headphones, and no sound at all. I have Z-340's and some Altec Lansing headphones that are very good. Please help quick....
