C-media usb headphone set: stuttering audio.

[Ron Sayers]

I have a pair of usb headphones from altec lansing that utilizes the c-media audio interface. I have a second pair of generic headphones that also uses the c-media interface. When I use either pair of headphones, I hear constant stuttering or skipping in the audio. The audio also seems to play slowly. I am using pulse audio currently. (I have also tried alsa and oss unsuccessfully). What is interesting to me is that they worked after the initial installation. One day the stuttering began and they haven't worked properly since. I don't recall intentionally changing anything at the time of the degradation. Audio through the regular speakers works fine.
