This doesn't happen in Ubuntu guest on the same host. This happens with both mplayer and vlc players. It looks like the sound driver consumes audio samples faster than it should. It looks somewhat similar to the currently open ticket https://www.virtualbox.org/ticket/4605 , except this ticket talks about different guest/host and about slower playback. What could be a problem? vbox-4.3.12 Yuri
