Greetings All

I'm using PD extended 0.42.5 and vlc 1.1.10 on Ubuntu 64 bit.  I'm trying to play the tutorial videos in vlc while pd is running but the two seem to fight over the sound card and PD seems to win so I can't hear the PD tutorial audio.  Is there a way that I can watch the pd video tutorials in vlc  and use the PD program at the same time so sound comes out of both?
