Help. I have a Dell Dimension 8400 PC with Soundblaster Audigy. After 3 years with no problems, a few days ago for no apparent reason, the volume started creeping up on its own slowly over a few minutes (about 0 minutes) to maximum volume. Can someone please help? I have to lower the volume all the time but it persistently goes up in volume after a few minutes. It is getting very frustrating as sometimes I forgot I have the problem and have a shock of my life when the sound is at full blast.
