My Ultra received 5.2.804553 yesterday. All settings were fine, except RAAT set on.

Already reported here, but +1 that the 5.0.805352 release solved the Plex issue. I can quickly forgive mistakes when corrected just as quickly. Thanks WiiM team!

This update will be installed automatically, right?
Or is there any option in the settings such as "keep me informed about new FW updates but don´t install yet"?

You will be notified in the app that their is an update to install..

If you want to avoid an automatic update, you could try unplugging your device between 2am and 5am local time as I think that is when it goes through the automatic updates process. Then when you apply power again you will be given the option to not update in the WHA

Either that, or it will be installed without any interaction from yourself, as occasionally happens.

Mine popped up as a notification of available update and I manually accepted it with the option to reject it. ¯\_(ツ)_/¯

You can also join a beta test which will delay any updates until you leave the beta test or the beta test ends.
You can also ask WiiM to 'whitelist' your device, but that would mean contacting them again to have the 'whitelist' request removed.

If you had rejected it, there is a very good likelihood that it would install itself at a later time, probably overnight.

 

[justMusic]

Hmm...in my case there was no notification ..just the message that "your device is up to date" (and showing the latest FW version) after I checked for updates.

 

[Ronnie D]

probably overnight.

Unless you remove the power overnight.
I am actually testing this at the moment with the last update that gave some issues. I am waiting to see if the new update would appear before updating to the older version. I will let you know.

Or is this the new version?

I have no need to do that, and as soon as I know there is an update release, I keep checking multiple times per day as in this song by @Wiimer.

1. Streaming Stability:
   • TIDAL Connect: Fixed an issue causing random playback stops.

Except it does not, still does it when using the Tidal app. It will take about 3 hours now, but it will do it.

If you haven’t already done so, raise a ticket via the more/feedback section when it next happens so WiiM can inspect your device logs. Are you on Android or iOS?

On Android, up to date version 16.

Will raise a ticket next time it happens.

From posts here and elsewhere over a long spell , the Tidal Android app does seem to suffer more of that type of issue than its iOS counterpart…

 

[Ange]

Still no shuffle mode worthy of the name in sight for the usb library.
Resume playback from where it was stopped and a real random mode, it"s not complicated.

 

[Fralle]

My unit atuomatically turns on randomly after the update. Am I the only one?

That seems to be a very old FW version...

Thanks for the info.
The version listed is from the build date of 20251218.
I wanted to see if removing the power from the WiiM Ultra overnight could stop the automatic update, but also allow bypassing a particular update that caused issues until a patch was released.
It would appear that you can, as a patch was issued on the newer FW. I still haven't updated yet. I will probably wait until the next FW update is released ( just to make sure).
