Might take a few minutes, but try turning off Enhancements and Spatial sounds in the Sounds Playback Properties. And try at least Studio Quality (24bit 44100Hz) in the Advanced Default Format. For PEACE, run it at 100% and use the Pre Amplifying to get it to a nice comfortable volume. Could help a little or be completely worthless but it doesn't cost any money. Supposedly this should minimize how much noise is passed through the chain. Cheers!
