Thanks Dan,

If I understand correctly,  you're suggesting to create a clickable 
button which will mute the audio, and then creating a macro to do that 
from within a script, which I then need to run manually?

I see two issues there, which were admittedly not in my original 
statement of requirements :-)

I'd like this to still happen if the screen locks due to inactivity. I 
haven't found yet what triggers that, or where to configure the timeout.

Secondly, will it re-enable audio when the screen is unlocked?

Cheers,
Richard
