WiimUltra usb noise

[Hyunjik]

When I connect an external DAC with a coaxial cable while using Wimultra, it breaks once in a while, so I can hear noise when I switch to USB output.
There's no noise in the Dali Epicon 2 speaker
Only B&W 706 speakers are heard.
It's stressful!

Turn up the volume

Do you have a trigger cable connected from WiiM to AMP?

No trigger connection.

In my case USB + trigger provided a kind of rfi interferance. It only disapeared when the trigger cable was in some positions related to the WiiM and Ultra...
Now I'm using WiiM Ultra internal DAC which, to my ears, is very very good.
