Issue:
Between tracks the DAC gives audible click and also a popping noise from speakers. Enough to ruin listening experience.

Tried:
Reverted back to using the AUX out and bypassing the DAC = works fine.
Same issue if I use a different USB power source
If I take the WiiM out the mix and use a PC as input = works fine with no clicks when playing tracks.

Setup:
  • Airplay from iPhones, typically Substreamer or Doppler, but have tried other apps like YouTube - same issue.
  • WiiM connected to Audioengine D1 DAC via SPDIF
  • DAC powered from Audioengine A1 USB

Any suggestions before I start thinking about changing hardware?

Likely caused by TOSLINK LED power cycling which WiiM does between tracks. Some DACs are sensitive to this and would produce a loud popping sound. I have reported this bug to WiiM support numerous times but so far it has only been partially fixed for Amazon Music streaming specifically. Same thing happens when you press pause button or skip to next/previous track. WiiM promised a fix soon, let's see if the latest firmware update fixes it.

Thanks, yes I have tried to rever tback to SPDIF but the noise makes it unbearable when using either Doppler, Navidrome or Substreamer apps.

Sometimes this occurs when the bitrate changes. Depends on the DAC I had a Allo Boss that did that.
