When I drive the audio output on my ATI Mobility Radeon HD 4250 Graphics using the Sound Settings to my HDMI output for some strange reason it causes Flash video to speed up with no sound. I switch back to my PC's audio output and it suddenly goes back to normal speed.
Any ideas?
Notes:
This happened in flgrx too. Using the open source Radeon driver with 3D Ubuntu 12.04 Google Chrome with built in Flash Also happened with built in Flash disabled and local Flash enabled
