I have been having the strangest problems with my audio settings. First, my speakers seem to go out of balance in system preferences by themselves. I set them to center and then days later they have moved. Also, I have the hardest time keeping my iSub at the same volume. It seems to move on its own as well. I genereally use the volume keys on my keyboard to adjust the volume levels. Is this wrong? This is just the strangest thing, and I don't think it should be happening. Can anyone give me any insight on the problem? Thanks.
