Did you power cycle the Ultra before attempting the factory reset?

Hi .....yes I did ....I always power off the ultra when it's not being used anyway.

Hi WiiM Team. Sub out when used in conjunction with usb out results in poor sound quality on the sub out channel. Sub out works very well with coax and optical outputs. Are you all working on this issue? A good example is Heart’s Magic Man on Tidal. I can provide more examples if needed.

Why would it only affect particular tracks?

Best providing the examples via a ticket to WiiM via the more/feedback section in the app just after playing them so they can also inspect your device logs for clues. If possible, I’d suggest you send them brief recordings of what you hear.

Not sure it doesn’t, but I really notice it on some tracks more than others.

Still has a standby screen bug.

When you configure it to turn off screen in standby, it only tuns off if you power the unit down with the remote. If you let the Ultra time out and go into standby, the screen does not turn of.

Also, please add an option to stop all comunication and power sharing via USB when on standby mode, many DACs will stay tuned on forever without this.

I have this behaviour as described by you, but I want it to show the click when I power it down by the remotecontrol. Now I have to wait till the timeout is passes, presse the powerbutton an then the clock shows. There should be an option to choose what you want in the preferences.
