Feature request: a switch to set audio output

[vmarks]

My Samsung qe55q80batx sometimes forgets that it can do ARC audio output.

So far, the only thing that causes it to use ARC again after it switches to internal speakers is to use the original remote control and select the created Home Theater input (on hdmi 3, the arc port). Switching to HDMI 3 via homekit doesn't do it.

I am either going to have to get a Toslink cable instead of HDMI ARC, or wonder if there's a way to force the TV to use the ARC output from homekit using this plugin?
