Hey all! Ive been having this crazy issue that if I put my master volume over 50% it starts making this high pitch squelching noise and it only goes away if you mute it. Im using a Creative SB X-FI sound card but thats not the issue. Ive replaced it with 2 totally different sound cards with the same result. Went in and completely removed all drivers and reinstalled with the most up to date drivers with the same result. Ive even placed the different cards in different slots on the board. I dont understand. Plus to make issues worse my mic doesnt want to work either. Maybe there is a conflict on my board or something? Im at a loss. Help!!
