No option to switch sound output mode from TV speakers to Optical

[GEORGE-VASS]

Hello Community!

There is a major issue with the Samsung TV's,
When watching Netflix 5.1 sound won't pass from the tv to the av receiver.

For this to work you have to change manually the output from tv speakers to optical in the menu.

Now I want to automate this with the Samsung TV component by simply reading the tv state.
I cannot find this crucial function to change the sound output mode from the HASS samsung tv component, nor any documentation.

Any help from the community or the developer itself is deeply appreciated.

Thanks a lot.
