Still work on Sequoia 15.1

I added a ding!
Inspired by the mute unmute ding meets / some headphones have.

if input volume of (get volume settings) = 0 then
	set volume input volume 100
	do shell script "afplay /System/Library/Sounds/Morse.aiff"
else
	set volume input volume 0 without output muted
	do shell script "afplay /System/Library/Sounds/Ping.aiff"
end if
