Robotic Static Sounds USB Headset

Issue: When using any USB headset or USB audio input device on any Macintosh with any operating system from 10.5.7 to 10.6.1, after about 10-20 minutes of use, all audio from the headset becomes garbled and has a robotic static sound quality.

Tested with: Dozens of different Macintosh Computers over the last 6 months with different USB headsets and microphone input devices.

Reproducable: Yes, via either Garageband, Ventrilo or a number of other software applications that do USB Audio Input
