Window focus based upon a notification sound

[Dorian (MJT support)]

I wrote THIS a few years back. It might be useful or it might not be useful.
Hope it helps.

That's very clever. Thank you, Dick. That makes me wonder if simply using GetPixelColor on that would work. I hadn't ever noticed the colour changes when it plays a sound. I'm using Win10. I'll check later.

The icon doesn't seem to react in Win10. It looks like it changes according to the volume/mute setting,
but not actual sounds.
