Option to select default audio output at startup

Issue:

Many people report an issue with HDMI ARC on LG TVs.

e.g:

https://forum.wiimhome.com/threads/lg-oled-b4-hdmi-arc-does-not-work.4260/
https://forum.wiimhome.com/threads/hdmi-arc-and-lg-smarttv-problem.5549/

I understand that the ARC specification is complicated—ideally, it would just work, but maybe there is a simple workaround. On my LG OLED55B42LA TV, I have connected HDMI ARC (for volume control from remote) and OPTICAL (for audio transmission)—the only thing missing is for it, upon detecting that the TV has been turned on, to automatically switch to OPTICAL IN instead of HDMI.

Solution: Add a function in the settings to select the signal when the TV starts up.

Example of implementation:

New Wiim Amp and LG B4. Same exact process and issues that you are facing @l743 .

All I want is to use HDMI ARC from my LG B4 ARC port (port 3 like in your pic) for audio and be able to control the volume with any remote (a Xumo streaming box in my case, but could be an Apple TV etc). I have to workaround by using the optical cable for audio and use the Wiim remote for volume. Pulled my hair out with multiple settings and configurations. I did send a feedback from the app to Wiim... we'll see. Makes me wonder if I should return the TV as the B4 seems to be a big issue for many in this scenario.

5. I don't have audio. Reboot tv/wiim is not solving problem. Soundbar Creative works fine with this settings.
