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

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.
 
I don't know if this will help, but this was taken from Amazon.
  • Tips: If the product cannot be recognized by the computer/phone or has other problems during use, please replace the USB cable or download the firmware upgrade from the SMSL official website
Downloaded latest software and still doesn't recognise it
 
Haha, I was getting confused with the sub comment. Glad it's been cleared up.

I have raised a ticket with Wiim support, so hopefully gets sorted.
On Reddit you said you contacted WiiM Support and they were hopeless. Is this a new ticket you’re raising?
 
Just ordered another from AV.com with 5 year warranty. Going to sell this one for £150 as it still works apart from the line out RCA jacks
Good luck with the new one. If you still have an issue, sounds like it might have been the smsl all along ;)
 
Any chance we can get the story of what happened to the RCA out ?
I just need to know....😂😂
No idea how it broke! One minute minute it was working then the next, the right channel only outputted sound, then a few days later the left didn't. And a few hours later the USB wouldn't detect the external DAC.

I managed to sell the old one and listed the issues. Managed to get £175 for it and the buyer said he knew a guy that can fix it.
 
I was just thinking of buying the smsl po100 for the ultra.
Your post discouraged me... Now you say the new unit is working fine?
Planning to run ultra > usb out to p0100 > coax to luxman da06.

Any advice?

I would just use optical (SPDIF) directly. You won't get anything better than 24/192 from the WiiM anyway.

PS: No need to post the same comment in different threads.

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. 🤷🤔
