Streaming with WiiM ultra transport into Volumio Preciso dac using usb out , I’m getting “static like” sound emanating from the speakers - rather akin to static from newly played vinyl.
This is only apparent during data flow, disappears when music is paused and doesn’t increase or decrease with attenuation.
Fairly quiet , but insidious nonetheless .
Awaiting delivery of replacement usb (type a to b) cable and usb isolator adum3160.
Possible the Volumio or WiiM is at fault - both purchased secondhand.
Coaxial out works fine and trying different usb settings within the WiiM app hasn’t corrected the issue.
I will update when I have the cable and isolator to hand.
Any thoughts ?
