Recently I have been having a problem in Tiger while changing the volume on my speakers. Sometimes while lowering or raising the volume on my keyboard the audio balance will shift over to the right or left side and blast into one ear (I usually have headphones on). I have learned to deal with the problem by leaving the system preferences audio panel open so I can quickly re-balance it. I did an erase and install with Tiger (not related to this issue) and was surprised to see the problem persist. Any idea? Thanks.
