Comment 13 for bug 345627

I also experience this problem when playing Flash-videos in Firefox, e.g. youtube. The video loads correctly. When the video starts to play, there is a scratching noise and after that only silence. The video playback than sometimes stops or displays only few frames and jumps. When I skip manually, it sometimes plays correctly for a few seconds. When I close the tab, the Firefox windows fades to gray and doesn't react anymore.

I experienced the same on a fresh Jaunty install on a friends laptop yesterday. This looks for me like a big and common problem and should recieve high attention/priority!
