TypeError: currentSwitch.playProcess.kill is not a function

Hi,

I have the issue that there is no running process anymore while on my iphone the sound-button is on. When switching off the sound- button the homebridge is restarted with the following logging:

[06/02/2021, 10:00:30] Homebridge is running on port 51826.
