Bug Description
When I open any video file from Nautilus or from VLC I see that video starts but there is no sound. It takes a few seconds and the sound appears, but since the beginning of the audio track. So video and sound are out of sync.
The workaround is to rewind the video at the beginning by using the slider.

The commit http:// cgit.freedeskto p.org/pulseaudi o/pulseaudio/ commit/ ?id=a813e855033 55496c7ea6397e3 9072fd8ffedcff (sink,source: Update sample rate if possible on stream uncork) causes an audio/video synchronization issue in VLC media player (2.0.1).
The audio track always comes with a few seconds of delaying after the video starts to play (but once the video scroll bar is dragged the audio should be synchronized with the video again)
After reversed this diff the issue does not appear in VLC anymore.
The problem seems to be VLC only; Totem and MPlayer works fine with this commit.
