Option to select default audio output at startup

[l743]

Issue:

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

e.g:
https://forum.wiimhome.com/threads/hdmi-arc-not-working-on-lg-oled-65b46la.4195/
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:

If this feature is implemented, would it not be possible to auto start from music streaming?

If the input can be specified in the smart presets that will be added in the future, it would be possible to automatically switch to HDMI by simply pressing the preset button on the remote.

This feature is only for detecting audio from hdmi or optical in, everything else is without changes.

This issue solve the problem when you connect HDMI and Optical in the same time.

Maybe you should contact LG as the problem is their TVs.

In the meantime, if you turn off the optical/HDMI auto-sensing, won't it work?

(I haven't tried it, though.)

Generically, it would be a nice to have to select:
- initial input
- power default volume level

I have old soundbar Creative Stage and works on HDMI ARC without any issues, plug and play - I think tv its ok.

I don’t have any problem at all with LG and HDMI. On LG it’s usually only one HDMI port who is eARC, the second one. The other three is not eARC compatible.

Which model of LG do you have? Many users reported problems with LG B4. On my tv, ARC work fine because I tested it with an old soundbar.

That really says nothing but that these two devices are compatible. It's no proof that your TV does it "right". The manufacturers of audio gear with HDMI ARC inputs are constantly chasing after adjusting to cover the inconsistencies in ARC implementation.

Are you 100% sure that you disabled eARC on your TV? WiiM devices do not support eARC.

1. Wiim Amp connected via HDMI to HDMI3 (ARC) in TV



2. Sound out to HDMI ARC



3. eARC disabled and digital sound output to PCM.



4. In Wiim app output to TV



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

Don't get me wrong, I don't question what you say. Just trying to help if everything has been covered. It's mostly impossible to tell from two or three posts how much assistance with technology or tech jargon needs.

Obviously you did it all correct and it doesn't work. It does work for other TVs with the same settings, so all you can do is talk to the manufacturers of all the equipment involved.

Of course, this thread should mainly discuss your feature request, apologies for distracting. But personally I won't vote for this because I think it's a complicated workaround for something that really should work to begin with.

Don't stop bugging LGband WiiM about it. Even if HDMI ARC is a poorly defined standard (and it is, very obviously), some of the leading manufacturers should be able to get this to work!

I understand that fixing HDMI ARC communication on the LG/Wiim side can be complicated. That's why I propose this solution, because the prioretization of input detection on hdmi/optical is missing.

Now I connected two signals hdmi + optical and use this script for automatic switching signal: https://github.com/lukaszradziak/wiim-auto-optical
When I turn on TV, Wiim detects hdmi signal, turn on wiim and my script switching to optical. Works fine but I don’t like additional dependencies. I don’t know what more I can do.

Maybe I can sniff HDMI traffic and send it for the Wiim developers?

Sending feedback to WiiM straight from the app (not through the Web) includes device logs with the ticket, but I'm not sure how detailed these logs may be with respect to the HDMI handshake.
