do not use system restore, it causes an error message with ts3 , so wont work, only way i found to fix prob is to set sound card to stereo, then back after i`ve finished using ts3

change sound settings to stereo all will be fine then, u will need to change back to last settings if u need it once exiting ts3

i had same prob, creative sound blaster needs to be chabged to stereo, also had similar probs elsewhere, had to change to no sound effects in sound card options hope that helps
