Hopefully someone here has an idea what the heck is going on with my sound. The rig I built with the parts TGS sent me has been working beautifully, the last week no sound. I've been just using the on-board Realtek. The OS is Window 7 Home 64bit. Device manager shows everything installed, drivers current but it wouldn't make a peep. Re-installed the drivers and with a couple of re-starts it was fine. Now last night same thing. So instead of just going through a bunch of monkeying around to get it to work for a little while I stuck a Creative X-FI extremme gamer in installed all the drivers and nothing. Re-installed everything still nothing. Going through control panel to sounds and going to speaker properties if I hit the test button I get an error message "failed to play test tone." Any suggestions on where to even start trying to fix this?
