For reasons, I had to start using a #Windows computer, and one of the most annoying things about it, was a frequent "dong dong" sound, in random, but short, intervals through the #Bluetooth #headphones, when I wasn't listening to anything.

It drove me absolutely mad.

I eventually found the solution: In the device manager for the bluetooth apapter, there's a setting "allow Windows to disconnect to save power".

Disable and reboot (it's f'ing Windows!) and done.

Perhaps it helps somebody.
