Why not just fix the issue? It was done in the beta version.

Even if it was truth, there was some reason why it was not implemented in the public version. Maybe other problems arose, or maybe it interfered with the seamless operation the team was striving for. I don't know.

We will never know, as I never got a response to my beta test report.

And as current @WiiM Support don't understand the issue, it is not something that has been discussed internally at WiiM, I think.

Smarter HDMI ARC: Your WiiM Ultra will no longer act as a TV speaker when not in HDMI mode—giving you more control

In my usecase it was better before, as I could use my sony tv remote control for controlling the volume while listening to streaming music. That was one remote for everything. As my tv is always on (screensaver with pictures), that was quiet convenient. Maybe you add that as an option to let the user choose which he prefers. @WiiM Team

Rather than enhance the VU Meter as is, why not create two meters to reflect the two channels. I know that they are practically just a bit of fun but if you offer it, why not stereo?

So you don't want the TV to change output to internal speakers when the WiiM input is changing away from TV and back again when input is again set to TV?

Because that is exactly what I want and how it has been working for some time now on the Ultra when the TV is already on and the WiiM is active.

It's been working for me before just as it should, no preconditions to be met.

Maybe your request could be implemented when "Automatically output audio to WiiM when TV is on" is enabled and mine when disabled?

My request is just the way it's been working before.

At a first glance it just looks like the "HDMI CEC" toggle had been renamed to "Automatically output audio to WiiM when TV is on", but that's not the case, the behaviour has changed.

The bug with the old setting was that the Ultra seemed to ignore it, more or less. The TV would still see the Ultra and act accordingly.

The much bigger trouble (for me) with the new option is that TV will always start outputting sound through it's own speakers when I switch the Ultra to any other source, no matter if "Automatically output audio to WiiM when TV is on" is enabled or disabled.

 

[Wiimer]

In the first place, the naming "Automatically output audio to WiiM when TV is on" is completely inappropriate and wastefully long and meaningless.

I have not observed any changes from previous release on Ultra.

That is still the bug. The TV still sees the Ultra, even when in standby.

It was also like that before, at least on the Ultra.

I don't know if that is the correct behaviour in HDMI on mode?

With HDMI mode off it needs to act in that way, else there is no way to control when the TV shall use ARC (TV input selected on Ultra) or the internal speakers (TV input option not selected on Ultra).

 

[hgo58]

Yes. Should just be "Automatic HDMI ARC mode"

 

[CliffyBC]

There is two different states of the HDMI mode, defined by the "Automatically output audio to WiiM when TV is on" setting.

With the setting enabled the WiiM Ultra shall always play the sound from the TV and will automatically switch on and select TV input when the TV is turned on. This is almost working correctly now (Some people want the TV to stay on ARC even when the WiiM is not on TV input. That is not the case currently).

With the setting disabled the WiiM shall only play sound from the TV when the TV input option is manually selected. That is almost working, except when the TV is turned on. In that case the WiiM Ultra is forcing the TV to change to ARC even if the Ultra is in standby and the TV input is not selected.

So enabling "Automatically output audio to WiiM when TV is on" will be for those that want the TV sound always via the WiiM, while when disabled, it's a manual task to get the sound via WiiM (turning on everything and selecting the TV input).

Thanks for your clear and concise explanation of the way that the Ultra and TV should be working together. As long as Wiim don't change the "Automatically output audio to Wiim when TV is turned on", I'm happy.

I'm not on the same page.... I want my guest to use my TV remote to switch on the TV with it's remote, as soon as they choose a channel with audio the Ultra turns on and the audio goes through the Ultra, then to a Yamaha amp to my 2 speakers and sub. The volume buttons on the TV remote then control the volume through the Ultra. At no time do I wish to hear the sh*tty speakers on my Samsung TV, that's precisely the reason I connect my TV via HDMI to my Ultra.
This is exactly as it happens at the moment on the old firmware and it appears to be the opposite to your requirements.

If Wiim can achieve what you require without messing me about and expecting me to make any extra button presses other than turning on my TV with its own remote then I'm with you.

That is terrific and I don’t want that to change for you. I think we’re going to painstaking lengths to say none of this is mutually exclusive — and I didn’t mean “same page” like we’re all on the same team and going to use it the same way, I meant that I’m hoping that @WiiM Support finally sees the idea and needs clearly.

What we’re talking about are preference options, ones that exist across every AVR and processor on the market for a reason. That’s all. Doesn’t detract from anyone.

 

[harkpabst]

I have not observed any changes from previous release on Ultra.

I can assure you that I did. It's with this firmware release 5.2.714249, that the TV starts playing through its own speakers when I switch the source using the WiiM remote or.the WiiM Home app.

Previously, the TV screen would still be on, of course, but no TV audio would be heard. That's exactly how I want it.

That is still the bug. The TV still sees the Ultra, even when in standby.

Funny side note: Yesterday I reconnected the WiiM Ultra (and the TV) to the mains power for the first time after the firmware update. I had not changed any settings, yet. Switching on the TV did not wake the Uktra from standby. TV sound sure enough did squeak through the built-in speakers. Isn't that exactly what you want to achieve?

This is how the Audio Input settings looked at this point:

Strangely "AoatWwTVio" was in the "on" position, but greyed out. Toggling the switch back and forth finally allowed to switch this option on or off.

Now, even if AoatWwTVio = off, switching on the TV also wakes up the Ultra, exactly as before, indeed. So, effectively the same as before.

What has changed is the behaviour with AoatWwTVio = on. When switching the WiiM Ultra to any other source while the TV is still on results in the TV and the Ultra playing their own audio.

That's unacceptable.

PS:
From now on I will continue to call this setting by its abbreviation "AoatWwTVio" because it's way too long to type it down every time I'm getting upset about it.

Strange, that was not how it worked for me. There was no difference between the states of AoatWwTVio except that the WiiM Ultra wakes up from standby and select TV input when TV is turned on.

In both cases my TV changes to external speakers (ARC) and in both cases changing away from TV input change the TV speakers back to internal.

I still see same behaviour.

Yes it is. But also when Ultra is in normal standby.

I tried to do the power off/on but as soon as there is power on the WiiM again the TV changed to ARC. With the beta version I tested, this was also the case but then, when the Ultra has booted and went into standby, the TV changed back to internal speakers.

What has changed is the behaviour with AoatWwTVio = on. When switching the WiiM Ultra to any other source while the TV is still on results in the TV and the Ultra playing their own audio.

That's unacceptable.

Maybe not useful when AoatWwTVio is enabled? I will never use that mode. My Ultra is not used as a soundbar.

When AoatWwTVio is disabled, this is how it shall work and how it has been working for the last 3-4 updates of Ultra. I don't remember what it did before.

PS:

Yes. I hope WiiM will change it. The old name was better. I will suggest using "Automatic HDMI ARC mode" instead.

 

[harkpabst]

I know our use cases are different and my Ultra definitely is the best soundbar I could ask for.

As has been pointed out e.g. by you and me and others like @tabata it really should be possible to meet both use cases, if only AoatWwTVio would work as.expected.

After new update when i change the source to wifi i my TV will flicker and use internal speakers.
This is purely madness right now.

If i have the tv turned on i want the sound to be played only through wiim. I'm sometimes playing on the console and listening to tidal. I dont want any sound from tv speakers then.

One additional little switch would be nice - "never use tv speakers".

I've set arc speakers on tv and i want that tv uses that until the HDMI cable is plugged in.

Right now i had to manually set internal speakers sound to 0. It's not a problem.
The bigger problem is that when i switch in wiim from HDMI to wifi tv screen flickers because it's switching state.
Yesterday i lost a fight with a Leshy on Witcher 3 because of the fact that my wife started streaming tidal xD

 

[8anasi]

I dont't know if this ie the right thread, but since last update vtuner become realy slow and some times unresponsive , does not load stations

I like the functions as they are now. In the rare cases where I am streaming and watching TV at the same time, I just set the TV on mute.

So I see we have multiple use cases here that can be hard to fulfill for all.

The TV flickering you get looks like a bug in the TV. I have never seen that.

 

[opiszon]

You can fullfill everything.
Just code an option to behave just like before the update. (Or just add 'never try to tell tv to use internal speakers').

ABout the flickering. It doesnt look like a bug.
Just a tv goes pitch Black for a fraction of second to handle the change state on HDMI input/arc - i'm just guessing yhat wimm just stops sending signal and tv just cycles to handle the sound output.

 

[Wiimer]

Anyway, my wish is that, as before, no sound should come out of the TV speakers at all as long as AoatWwTVio is on. I don't want to use the TV speakers, which is why I have the WiiM connected

And I don't want to have the sound from the WiiM Ultra unless I watch a movie. Then I will select the TV input manually on the Ultra and would like if the TV changes speakers automatically. It shall never change to ARC automatically.

I think it will be possible to have both these use cases with the current HDMI option. It "just" needs to be implemented correctly and not as currently.

PS: After testing the different HDMI options with the latest software I now have bad lib-synch. It was working ok before my testing. I don't understand why.

 

[adias]

HDMI… a rabbit hole of different implementations. I know hifi manufacturers who never considered tackling it for that reason.
