turning audio playback volume off

1
Hello,

I am a very inexperienced programmer, trying to program for the first time using
Psychophysic Toolbox.

I want to program a video that only plays when you hold the mouse pointer over the
embedded video screen.

I have got the video image to freeze when you move the mouse away, but because the loop is
constantly refreshing, you get a juddering noise on the audio.

I thought the easiest solution to this was merely to set audio volume to 0 when the video
playback pauses, and then back to normal when it recommences...

But I can't work out how to do this! After three hours of trying!

Please help.

PlayMoviesDemoOSX.m contains everything you'll need.
Press Cursor down/up keys to pause/resume playback,
then go through the code that handles those keys
to see how it is done.
