I'm using Mplayer 2.0b9r5 on a PowerBook G4 running 10.4.11.

I have a nice USB headphone amp that doesn't sound so nice anymore.

I first noticed distorted sound from one USB port, then another. I then sent my amp in to be checked out. It's fine.

Today, I got the amp back, and decided to try a powered USB hub. It worked great! Until I played a file in Mplayer. One by one, I heard each of the four ports on the powered hub get 'ruined' as I first played music from iTunes (sounded great), then played a video file using Mplayer (immediate and permanent distortion).

My USB ports seem to be ruined.

Any ideas? What can I do? I've already reinstalled Tiger. Can anyone offer some insight?

Please - anything.
