I have an iSub hooked up to my G4 cube running 10.2.8 (soon to be 10.3). My problem is with the output volume of the iSub. I have it set to a certain level and when I log out and than log back in, it has changed, it always decreases a few notches, even if no one else uses the computer. It's not a set amount either. Sometimes it will only decrease 1 notch, sometimes 3 or 4. Can anyone think of what may be causing this, or have a solution. Apple can't explain it, neither can harman-kardon. Sometimes it even shuts off completely, the volume will still be up, but it won't function, I have to restart to get it to work again. Thanks for your help.
