video sequencer - audio - totem

I added some sound strips ( mp3 HD ) into my video sequencer but was getting no sound when hitting alt-a for the preview. I found if I shut down Blender, start up Totem, start playing a video in Totem, and then re-start Blender the sound in the preview now works. I can then shut down Totem and the sound preview continues to work until my next reboot.

Also, if I start Blender first and then start Totem while Blender is still running Totem will playback the video at one or two FPS.

Anybody ever hear anything like this?

Thanx

Ubuntu 9.04
Blender 2.4.9
Totem 2.26.1
