I've recently freshly reinstalled Ubuntu, and Mythbuntu, on all my computers.

On one of my computers, Mythbuntu 11.10, when I play a video, when it starts, I get a burst of white noise (static) that stays on.

If I stop the video and restart it, the noise goes away.

Sometimes if I fast forward or manipulate the video, the noise will start. It seems to be initiated, and stopped, by starting or interacting with the video.

Any ideas as to why this is happening and how I can get rid of it?

Now that I have some free time on the holidays, I've made a video of the problem and uploaded it here.

As you can see in the video, it starts playing normally. I hit the skip forward button a few times, and it's fine. After a few presses, you can hear the white noise burst. After that, the noise comes or goes at each press of the button. Each button press will randomly initiate or kill the white noise.

Also note that in the video it started without white noise. Sometimes, however, the white noise begins immediately on video start. Lastly, in the video I just pressed the skip forward and backward buttons. However, pause and and most any other button will also sometimes trigger the white noise.

I hope that makes much more clear what the problem is.
