Audio Buzz help

[wallyh]

Hi,
Getting back into RC again after about three years. I used FMS with my old computer with a USB sim cable. This did not work with my new computer and the new FMS. I downloaded Propoplus and wired up a cable. All works except I get a buzz instead of the motor sounds. I have gone through the step by step calibration but the buzz is still there. Any suggestions? FMS flight sim works great.

Wallyh If you are useing your air plane transmitter you need to remove the crystal in it to get rid of the noise.

If removing the crystal doesn't work, go into your sound card's mixer and mute the channel you have the cable plugged into, usually "line in".
