I think this might have something to do with kdenlive needing to use ALSA (not pulse) and pulse running all the time in kxstudio.

?

When I import an .ogv to the stage the audio is a stuttering, digital mess.  

My first inclination is to attempt to stop the pulse daemon from running so ALSA can do its thing.

Would this be a step in the right direction?

Thanks.
