Public bug reported:
When playing videos on YouTube in HTML5 instead of Flash Player, at
times during playback, the sound skips in places. If you go into the
"System Monitor", select "PulseAudio", right-click and select "Stop
Process" and then click "Continue Process", the problem goes away until
next time.
It happens at random. I find this problem is most likely to happen when
clicking the time bar to watch the video at a specific time or replaying
the video.
It only happens on HTML5 videos.
By chance I found that stopping and starting PulseAudio is a temporary
"fix" each time this sound skipping occurs.
Since I prefer HTML5 to Flash, for obvious reasons ;) I now watch more HTML5
videos. I have joined the HTML5 trial on YouTube, which means most videos are
in HTML5 instead of Flash:
