2 out of 3 times when I place my curser in the timeline and hit the space bar to play back video in the timeline the audio is replaced by a Buzzing sound. If i place the curser in different spots around that one and try again several times the audio will finally play. The video was exported out of Premiere Pro and transcoded in Encore (1.5). The buzzing is definitly coming from the program and not the timeline. Anyone else with this problem? I updated every driver I could find and still no problems. I had no problems with 1.0 on my audio hardware. Any thoughts?
