I am running Dark Alliance on PC through Steam. I just opened the game after downloading it and noticed an odd sound:

While the game is running there is a slight buzz coming from the speakers.

After testing causes I realized it was coming from this game and that:
1) Volume control does not change the volume of the buzz but did change the volume for the game
2) Switching the sound over to headset does not stop the buzzing in the speakers nor does it start playing through the headset
3) Closing the game will end the buzzing
4) It is most notable when on the opening splash screen or options menu
5) Even when playing the game the buzz is in the background constantly just loud enough to be noticed
