[ubuntu] HDMI Flashes black (reset?) when audio is started.

view story

http://ubuntuforums.org – I grant that this could be the issue of the TV, but it could also be an issue with drivers etc, so I'm hoping to get a troubleshooting process going. Issue : When a program or task is started which contains audio, the screen flashes black for a split second (coming back fine), and audio engages a second later. The same sometimes occurs when Audio disengaged. For example : If I open a youtube video, the screen will flash black for half a second, and the audio will engage one second into the video. There are no further issues provided the video remains open. The same occurs when playing (Hardware)
