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)
