WiiM Ultra Firmware v5.2.715362 - Apr 29, 2025

It probably isn't, since they mention standby mode.
So if wiim is not in standby and we are listening radio for example,
and someone turns on tv will tv see wiim and not use tv speakers since wiim is not in standby?
It should never see wiim if HDMI input is not selected
We will see.
In such a case, it would be better to turn off WiiM and then turn on the TV. 🤔
 
I am having major audio sync problems ever since the latest updates, and I have not experimented with any Dolby settings or anything like that. Am I the only one?
I also have audio sync issues on my Amp Pro. The issue temporarily goes away if I reboot the Amp Pro, but unfortunately it comes back afer a while. :confused:
I'd suggest to open a support ticket.
 
Hi SomiKnight,

Our team is currently reviewing this use case. That said, we believe most users are unlikely to listen to the radio and watch TV with audio output simultaneously—especially when the external speaker and TV are positioned close together, as it would be difficult to hear either source clearly.
In this use case (Automatic HDMI ARC is OFF) the TV shall only charge to external speakers (ARC) when I manually select the TV input on the WiiM Ultra or manually select external speakers on the TV. This do currently work, except when the WiiM Ultra is in standby.

So no need for an additional setting. Just make sure that a WiiM in standby don't force the TV to ARC, when it is turned on.

What you suggested is one of biggest problem of behaviour of hdmi arc input, when every option is ticked off, and WiiM is in standby, when you turn on tv it detects hdmi arc and does not use internal speakers,
so in your scenario we would hear nothing from tv.
But even if that works when WiiM is in standby is not enough as i said before, we need option so hdmi arc is never detected by tv unless we manually select hdmi arc input.

Exactly, as said in #83. I have tried to tell @WiiM Team this since the Ultra was released (I have several tickets trying to explain this). WiiM even created a Beta test version where this was fixed but never released it.

Let us hope this time is the lucky one.

Thus, once the features described in the release notes are implemented, it will be resolved, right?

@hgo58 says "This do currently work, except when the WiiM Ultra is in standby."

We can hope so.

I just don't see the need for a separate setting for this. Maybe there are use cases I don't see?
 
Probably around 95% of my TV viewing is done using the built in speakers for the audio, but on rare occasions such as a music programme, or possibly a film that I might want to watch, I will listen via my Ultra.

There should be a setting to allow the HDMI input to receive TV audio only, without any HDMI Arc/CEC “Features” whatsoever, and then I might just be able to use this input instead of using the Optical input.

I don’t want the TV to do Any of the following,

Turn on my Ultra
Change the Input on my Ultra
Control the Volume of my Ultra with the TV remote
Silence the TV built in speakers
Turn off my Ultra

It would be great if this could be done.

Unless I’m mistaken, aren’t all those CEC functions apart from silencing the TV speakers which would be a TV or ARC function? I already don’t use CEC in my setup as I use a Harmony Hub and remote which needs to know input and power state and CEC can mess that up.

I’d also note that I can see a use case where you could have the tv on just for visuals (say with a football game on) while listening to music on your Ultra which WiiM seemed not to see as a use case if I understood their comment correctly.

And that use case had always been covered, except for this one odd firmware version that tried to make HDMI smart. :)

You cannot get any sound from the TV without ARC. That is the special wire in the HDMI cable retuning the TV digital signal (e.g. PCM). The CEC is a control signal running on another HDMI wire. You may disable that but will lose things like volume control. That could be ok for some but not for me.

You can get special HDMI cables where the CEC wire is disconnected. I think that would be the solution for you.

I'm pretty sure that all CEC power related settings can be switched on and off independently from HDMI ARC with other devices (and that's what I had expected the CEC toggle to do on the Ultra).

I'm not entirely sure if this also affects volume control.
 
I am using wiim all day because my PC is connected to it, it's never in standby during day,
so when family member turns tv on ti hear news, what happens?
When you turn on your TV, the WiiM device should automatically switch to HDMI input mode and begin playing audio from your TV. This behavior relies on HDMI CEC being enabled on both your TV and the WiiM device.

If it doesn’t work as expected, please double-check that CEC (also known as HDMI-CEC, Simplink, Anynet+, etc.) is enabled in your TV settings. Feel free to send us a feedback ticket via the WiiM Home App if you need further assistance.
They hear nothing, auto output is off, wiim not switching, and tv is silent.
How can they hear news for example?
They have to switch input and listen to news through hifi?
But we don't want that, auto output is off for that reason, makes no sense.
Thanks for response and considering our request.

The volume control, speakers switch and auto power on/off are all part of the CEC protocol, so disconnecting CEC will turn all this off.

I think the "Smart HDMI" was a try to handle this in a smart way. There are however too many use cases to be able to satisfy everyone in that way. Better just to have it like now, except for the bug in standby mode when "Auto HDMI ARC" is off.

For the complete removal of CEC the special cable/adapter is a good solution.

But i do not want that behaviour, its turned off in wiim app, so it should not start playing tv through wiim.

I am listening some podcast for example, someone turns on tv and i do NOT want to stop listening podcast, and i want tv to play from his own speakers and whoever turn on tv can listen it through tv speakers.

This should not be complicated,
tv should never see hdmi arc connection to/from wiim unless i manualy select hdmi arc input.
When i pick hdmi arc input i should hear tv from hifi, when i dont or wiim is in standby tv should use his own speakers.

Personally I want the opposite behavior.
I.e. I want the TV to *always* use the HDMI-ARC output via WiiM and *never* to use the TV built-in speakers.
This means that the TV should wake WiiM if it is in standby, and also that the TV switches WiiM to HDMI input if currently a different input was used for playback.

@WiiM Team IMHO if all of these HDMI-ARC use-cases are implemented the related behaviors should be configurable and clearly labeled in the WiiM Home App.

Both use cases (always ARC and only ARC when selected) is possible with the current implementation.

Only the bug with WiiM Ultra in standby and the "Auto HDMI ARC" off needs to be fixed.

(If I repeat this enough times, maybe it will get fixed?).

This is how I would like it to work, but sadly I don't think it ever will.
Can you use an optical connection between your TV and Ultra? This connection method allows me to have full control of where the TV sound actually goes.
