Universal mute - causing problems with Flv's?

Hi,

I have 3 Flvs (brought in using the component inspector) I’ve coded them so when one finishes it plays the next - on one big loop…

My problems is, I need to add a mute button that mutes all sounds and the different flvs carry on playing muted… then a button to bring the sound back

I’ve been searching around but haven’t had any luck
