Bug Description
Ubuntu 11.10, clean install, Thinkpad t60 [200772U]
Sound worked properly with good output in 11.04.
In 11.10, sound playback is distorted, with noisy clicks and 'burps.' The problem is worse when I move the mouse cursor by any method, including trackpoint or touchpad. I am not using a wireless mouse. I have installed ubuntu-
Will happily post additional troubleshooting info.
