           Summary: VLC audio track delay
    Classification: Unclassified
           Product: PulseAudio
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: core

The commit
http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/?id=a813e85503355496c7ea6397e39072fd8ffedcff
(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.

* pulseaudio/libpulse 2.0-1
* vlc 2.0.1-1
* gnome-shell 3.4.1 on Arch x86_64
