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
