Wiim doesn't detect my SMSL PO100 2024 (not Pro) when connected to USB

[Kdot89]

It powers the device on, but nothing showing in Audio Output. However, when I connect it to my Pc, the Po100 appears with no issues.

Trouble shooting I have done :

Power cycled Wiim Ultra Changed USB cables (4 cables used). Fully rebooted Wiim Reinstalled the app

I connected my Fiio M21 and again just charges the device. Unfortunately, my Wiim is not under warranty as it was bought used and Wiim customer support have been useless. Just wondering if anyone else has experienced these issues? My RCA jacks on the line out are out of order too but that's another story.

Not exactly.
I was thinking of 2 different solutions:
Running usb from ultra to the luxman.
Using the smsl po100 between the ultra and the luxman.
Different solutions.
I currently run coaxials, but people say it has more jitter.

Run the Smsl PO100 Pro between the WiiM Ultra via usb and out of the Smsl to a dac via a good quality rca spdif cable. I use it this way and it’s great. I have tried all the other combinations out of the WiiM Ultra, and quite frankly this sounded the best by far. I would have retuned the WiiM if it weren’t for how good the Smsl PO100 PRO improved the sound. You will be pleased with the improvement.
