A95l set toslink volume programmatically

[GrahamB9]

Does anybody know if you can use the AudioManager API to programmatically set the toslink volume?

I want to write a tasker plugin so I can link the toslink volume to the main volume.

Is there a better way?

Thanks

Hi, how do you connect the AudioManager API to the TV and what is the full model number of the TV? Can you also explain a connection map of all the devices to understand?
