Audio intermittently cuts out

Hi, I am having a problem with the TX1. When I try to view tutorial videos, the audio intermittently cuts out. I tried replacing my HDMI cable, but the problem persists. Any suggestions?

Thanks!

Is the content local, or does it stream over the network? Obviously it may be difficult to do anything if the content is networked, but if there is a way to download a video file or other content locally and reproduce the issue then it can be examined. Do you have information available on how we might reproduce this for debugging?
