Pc audio My 2 yr old Dell pc now plays ALL audio as chopped up, skipping playback. This happens with the speakers, with the front headphone jack, or the rear sound card jack on headphones. The speakers work fine on another pc. ALL audio is affected, CDs, mp3s, wav files, even startup sound files. If I display the Task Manager window and the Performance Tab, the chopped up sound is directly related to the spikes in CPU usage. Any ideas for additional troubleshooting? Thanks
