Sounder is not silent when idle

[KitronikLtd]

Describe the bug The sound pin is constantly making a low level noise when idle. This occurs after the first use of a sound.

To Reproduce Steps to reproduce the behaviour: Pick any game that has a noise that can be made once and doesnt make a noise on startup Listen to the sounder - notice it is silent. Make the noise Listen to the sounder - notice it is now 'hissing'

Expected behaviour sounder is silent when not actively being driven

Noticed on a hardware revision of Kitronik platform - to make the sounder louder. But has been present since ~2019 (Tried on all archived hardware and software)

Can you try this build: https://arcade.makecode.com/app/e7e4c9577362f4c8da0344f4d5438b3f5804627e-efe0a508d3

I don't currently have SAMD51 hardware to test.

Have tried the build but it is still exhibiting the same behaviour I'm afraid.

I guess it will have to wait until I'm back in Seattle in Sept then...
