Auto-Sensing of HDMI and Optical issue

[Ozpaul]

I can only think there is a hardware issue that is not easily fixed by software. Once you are accustomed to auto switching, its failure is more annoying and having to tell others about using the remote is also annoying...

The same for me… I have a WiiM Mini connected to the Ultra’s and the same problem. I have the latest software versions - WiiM App Home & WiiM devices.

It would be really nice to make it working as expected. Now when I use AirPlay on Mini’s, I have to change the input source on Ultra’s to “Optical In” manually…

I also use HDMI ARC input.

Same for me, sent a ticked about it and received info that with HDMI input active Optical In auto-sensing does not work. I don’t know the reasons, it was not explained and I am afraid it wont be fixed. They advice to physically disconnect HDMI cable when not used which is an absurd.
For me Optical In auto sensing doesn’t not generally, not only on active HDMI input and I have to switch manually to Optical and from Optical. And it sucks having in mind convenience of auto-switching of rest of inputs.

I don’t use the HDMI input, but do use the Optical input, and the auto sensing works well for me.

In previous firmware versions the HDMI ARC and optical auto sensing was the same. This may indicate that they use same hardware? This could make it impossible to automatically detect if the input is HDMI or optical.

Too bad. This is a big flaw.
Probably inside of the device the hardware is made in such a way that the digital signal from HDMI and optical signals go through the same channel and it is difficult to detect at the processor level where does it come from... :/

However, in this case, if it is unrepairable, then in the WiiM Home application it should not be possible to activate auto sensing of both HDMI ARC and Optical In. There should be one of them to choose from. Otherwise, it is misleading.

If there is only signal on one of the inputs there is logic that can find the active input. With signals on both that is not possible.

What about Line In ? This is the same case ?

I seem to recall WiiM saying that the same hardware was used when this was first brought up a while ago

Auto-sensing from HDMI to line-in while idling should work.
