USB output requires reboot

[Burnside]

I just got the update and installed it. You're right. I guess I was being hopeful! Unfortunately it didn't work and the issue persists.

Fyi, my setup is

TV (HDMI ARC) > WiiM Ultra (USB, 12v trigger out) > Audiolab 7000A (USB, 12v trigger in) > Monitor Audio Gold 100 5G

With this exact setup, but using optical instead of USB, it works flawlessly and is seamless. No physical interaction is required with the devices.

Ticket number is 518616.

@RyanWithWiim @WiiM Support @WiiM Team - hi, any updates on the ticket number mentioned? Thx

This works for me most of the time, however, sometimes as Dazza experienced, it won't detect at all and I needed to physically reconnect the USB cable to force it to detect again.

My Ultra is going into an integrated DAC/Amp - Audiolab 7000a.

Also, still no updates from WiiM support team, however, I noticed they posted today that there is another firmware update that mentions USB optimisation, so I wonder if this will have any effect on our problem..

Unfortunately the recent firmware update didn't address the issue, and the issue persists.

I had the same issue with my dac. Reported it and they said is a compatibility problem. I decided to use a ddc from douk audio that is quite inexpensive to solve that issue and to use I2s connection as a freebie. I use the Ultra in the living room and my wife couldnt handle the fiddling. Since the DDC is always on problem solved. Until last night and the new firmware. I had to reboot to make it work again. This morning more of the same. I need to wait and see if happens again

Yep I am in the same situation - trying to make it as easy as possible so that my wife can also enjoy the great audio. I now have it set to optical as default as that works the best in this situation. I guess when doing more critical listening and enjoying music, I could manually switch to USB output.

It's interesting you mentioned using a DDC, as I have recently purchased a SMSL PO100 Pro to try to overcome the issue as well since it's always on. It hasn't arrived yet so I can't test, so I hope it works.

Update from WiiM support team - sadly they have also told me that it may be a compatibility issue, and to seek a replacement with my retailer.

Unfortunately I can't say I'm convinced as it seems to be happening with a few others - but I totally understand that it's more than likely that they can't design the Ultra work with all types of DAC's and have to agree in that regard.

Here's hoping adding the DDC may help.

My problem is that the dac doesnt have optical in. Coaxial is buggy and only accepts rates up to 96. With other sources it works up to 192. And USB keeps disconnecting. So I had to get the DDC because fixed output resolution was implemented not so long ago and I had to change outputs constantly depending on what I was listening to
