And still no HDMI fix?

It has been in Beta Testing and approved. So why is it still not included?

I promised my wife that its gonna be fixed this month

 

[Aquaman]

Where‘s the clock during playback?
I know, I‘m an impatient son of a bitch.

Localization: Added German language support for the device screen.

I never even realised my Ultra didn‘t speak any German.

This looks like being a release with minor, mostly unimportant updates, not including any of the important fixes or additions.

Let us hope for the next

What does “Refined the logic for default DAC filter selection” mean ..

What does “Refined the logic for default DAC filter selection” mean ..

A very valid question.
I‘d also like to know what this means.

You are one ungrateful bunch.

Volume Feedback: The screen now wakes to show the volume bar when adjusting volume, even if the display was off.

I'm not convinced some will consider that an enhancement.
I for one think that off should mean off.
Unless this is an option?

Anybody?

I'd disagree that it's an unimportant update, for us Plex users. I'm less interested in remote Plex servers, but more curious if this solves the recent Plex issue that has forced me onto a beta version.

What does “Refined the logic for default DAC filter selection” mean ..

Probably just an ease-of-use improvement in the DAC filter selection menu? (note: I did not yet receive an update so we've yet to see...)

 

[Mr Ee]

TIDAL Connect: Fixed an issue causing random playback stops.

Looking forward to this one! Been bugging me for ages.
And I see it's starting to be released on other devices too (e.g. Sound).

Tidal integration in the WiiM Home App has been working more reliably in that respect, but I want it to work both ways, of course. I sometimes use one, then again the other.

Let me know when it has headless plexamp integrated then it is something good.

For me it surely is. I was hoping it worked like that.

Welcome.

I was hoping wiim would implement it similarly to how it works on the amp pro (and maybe the amp too?)
Not got the ultra firmware yet but I suspect it will behave like the Sound, with no option to prevent it.

Yep.. still no update yet I’ll check once it’s downloaded and installed
