I have started to get a strange problem whereby, the sound or tone when you hit press a key on the keyboard to perform an unavailable/invalid action (user interface sound?), is occuring all the time.

For example, whilst typing this post each key generated the tone.

I did restart when this problem initially came up, but now it seems to have developed into something worse. I'm sure it was only happening occasionally before now.

Is there an obvious cause for this problem that anyone can think of?

This is on a MBP 2016, 13 inch.
