^I’m happy that WiiM kept the fine adjustment on the volume knob. Those 0,3 dB steps are one of the great functions on the products.
Of course coarser is nice for those in need.

(with mono function / precise balance, on all Wiims via Wiim Home

Hi
Somehow the volume keeps adjusting itself from 100% to 97% after a while.

I've now reset the Wiim Ultra to factory settings and am keeping an eye on it.

Yes, I also observe the volume to be randomly setting itself lower, could not find the pattern for it yet but it is definitely after the last update that was again installed without me knowing, something I hate the most!
Also, the screen now randomly turns itself on for no reason when in standby, and after the set timeout goes off again. Happens several times a day.

I also see that wiim ultra is leaving standby mode without any reason. My device is connected with my TV via optical in. It is also connected to my external dac via USB. All auto sensing settings are disabled. Nevertheless, I think that wiim ultra senses the optical in and leaves standby mode without any other reason. I recently opened a ticket and support told me that the last time wiim had switched on was due to me changing the volume. Still, I think that wiim has a bug and switches on randomly. Or perhaps my device has a hardware issue and senses phantom screen touches or phantom audio volume modification... I will keep an eye on this issue

It will switch on occasionally to check for updates.

I complained recently about having firmware updates forced onto my Ultra, but the Wiim response to my request to change this was somewhere between enigmatic and 'No'.
Despite being connected almost constantly I am still on f/w 5.2.715362, and don't even get the blue highlighters from the previous version to say an update is available. Yes, I have power-cycled and disconnected (twice).
In view of the issues reported above I don't know whether to feel neglected or happy!
Is anyone else still 'In Progress' ?
