Mine got it in the last day or so too.
And I see there's a beta released on Jan 14 too that I hadn't noticed before. Not that I check the beta screen very often so it may have been there for a week already.

Yes, that beta version has been there for about a week, and I’m surprised that nobody has mentioned it before.

I wonder what poeple have in their heads. You cannot seriuosly expect that WiiM integrates every available streaming service.

I'm always amazed by people who think that only their own wishes and ideas should be taken into account—and that everything else is complete nonsense.
They probably yell across the restaurant, "Hey, why do you want a steak? Order some pancakes, that's what I had and I'm happy with it."

I searched for updates last night without any success
But this morning it had arrived and my Ultra has just been successfully updated.
All times in CET since I'm in Sweden

Just had the update only I haven't! My Ultra has just gone back in time.
Left it unplugged for 15 minutes still showing older firmware than I already had.
No spectrum analyser, anyone else had the same or have I got to put in yet another ticket?

That's a beta version.
You won't move off that unless you choose to.
Strange if you didn't specifically choose it, which you imply you diidn't.

Edit: actually, it's not the beta I thought. All those 3s and 4s confused me!!
I saw 733433 on the 24th, not 733343 on the 23rd.
See how confusing it is?!

Enjoy the Kylie firmware edition. (Step back in time)

I was on a beta firmware for spectrum analyser several months back but I came off that and I was on the latest firmware until today when I had the prompt come up to update to the latest one. Instead I got one from way back . I think you could be right, WiiM may think that I'm still on a beta test. I've sent a ticket asking that they send the correct version down to me. I agree, all those digits in a row are confusing to me as well.

I received 5.2.804553 today and music is cutting out with Tidal, and now Linn radio

Desktop system working with Tidal

So far ARC from TV no issues, only streaming music.

using Ethernet to Ultra.

When I click on a track in Tidal from the WHA, the next track starts playing.

I opened a ticket. totally baffled. restarted and unplugged the Ultra, restarted the router just in case.

 

[Saponetto]

Just updated.
First noticeable thing: Tidal Desktop for Windows -immediately- finds Ultra and Pro+ and solidly grabs both!
I know it's a little thing for so many of you, but I'm satisfied.

I received the latest update just now. Did not really notice any major changes, but it continues to work fine.

Got this update on my Ultra. It has the same problem now that I reported on the latest WiiM Amp update thread where Plex will not stream losslessly (and capped at 16bit/48kHz). Support ticket opened.

Got this email this morning from support after I put in a ticket because I got sent an update that was several months old

"We will be pushing a new version, 5.2.805336, to you today. The current OTA version has issues with playing Plex, so we are releasing this new version to address the problem."
Maybe good for you as well?

Still no idea about the Dac Filter type enhancement..

Confirmed it was working fine yesterday, transcoding FLAC to MP3

Let's hope it doesn't take days to be pushed to our devices as is usually the case...
