Battery Manager and Pulseaudio are interfering with each other

[Robertert]

When I boot my system while connected to an external power supply my power manager says that it is charging. Once I start pulseaudio, it changes to discharging. After ~3 minutes of uptime for pulseaudio, it seemingly crashes - audio stops and a constant buzzing noise starts. This noise is not affected by the volume control.
I run "killall pulseaudio" which stops the noise, and at this time the battery manager goes back to charging. I run "pulseaudio --start" and I am right back where I started; the battery manager says discharging and pulseaudio will crash in about 3 minutes.

Welcome to the forum, Robertert.

Did you install with just the Linux Mint ISO or did you install the Linux Surface code?
