I recently picked up a new Wiim Amp Ultra and have been enjoying it so far. I have a pair of Polk ES15 speakers connected along with my computer through a optical cable and a Ethernet cable. The Amp Ultra is plugged into a power strip which then goes into a battery backup. Today while it was on the optical input but not being used, the Amp Ultra hard rebooted. And I'm fairly sure I heard a popping noise. It seemed to have lost power temporarily because it bugged out with the screen and play button light flickering. It booted back up normally but wanted me to set it up again until it registered an Ethernet connection which brought back my setup. This was very strange and worrying. I contacted Wiim support but I know if may be a while before I get an answer. Should I have Amazon replace it since it's still within its 30 day return window?

Welcome.
They do reboot themselves occasionally (every few days). It could have just been that.
As for the very faint pop, that's not uncommon either. Both my amp pro and amp ultra do it.

I should say, I think the pop was directly from the unit and not the speakers. And I guess a reboot isn't the right word for it. It was like a sudden and catastrophic loss of power and made the entire unit freak out.
Yeah, you should have 
Not had a unit pop!

Hi StormyC93,
The Amp Ultra automatically reboots every three days to perform routine housekeeping. During this brief process, the screen will turn off momentarily, and the play button may flicker—this is expected behavior.
If you’d like us to double-check your device to ensure everything is working properly, please send a feedback ticket via the WiiM Home App. We appreciate your continued support and patience!

What time did this happen? I would expect an automatic reboot to happen overnight.
Does the periodic reboot happen even when the device is in use and playing back media?
If so that seems like a suboptimal implementation.
Is there at least any warning for the user?
Wouldn't it make more sense to postpone the reboot at least until playback is paused; or even better, until next time the unit goes into standby?
To make things worse, during these reboots, the trigger output becomes active and switches on my power amplifier for a few seconds.
Stable software operation because of these resets is nice, but less reboots and no useless activation of the trigger output would be better...

The Amp Ultra does Not have a trigger output, and shouldn't be connected to a power amplifier.

I am still looking forward to having a solution to this rebooting. I really don't see why it is needed unless there are some software bugs (memory leaks) that needs clean up.
I don't like that this is happening at all but it could at least be limited to the night only. Today I was playing a random playlist and at about an hour into the playing I paused it. When returning home from shopping a bit later I would resume the playing but the device had rebooted and the actual random list was gone. When restating the list I got many of the same tracks again.
This is not ok.
Have not seen a sudden reboot while the WiiM is playing myself (yet) but comments above show that it does happen. This should never happen. Maybe only in "extreme" cases when there is a critical operating system fault but even then just pause the music and display a "reboot needed now" message in the app and on the screen of the devices that have them.
Please WiiM, advice and take action.

It's not a reboot while playing I see. The device reboot while being in standby for some time. The issue is that this reboot clears the (random) playing queue, so you have to start over.

Pretty sure the reason probably is memory leaks and instead of fixing them it is easier for WiiM to annoy everyone by forcing the device to reboot periodically. Since I power my Amp off when not being used I have never experienced the reboot.
