Intermittent clicking noise in Gustard R26 DAC


I bought a R26. It is the first r2r dac I have and sounds more refined to my ear. However, it has intermittent clicking noise when I click on / switch to another track during playback. It will remit two clicks. Interestingly, these clicks only occur in SPDIF ports, not USB.  Is it normal?  Are you experiencing it?

This phenomenon is exactly the same with Schiit higher-end DACs like Bifrost and Yggi. Schiit says it is the muting relay doing its job whenever SPDIF data stream is interrupted.

The only time I had that issue was when I was using the internal streamer and Audivarna software.  I didn't have that issue when streaming with a Node or Innuos streamer, but they were connected by USB. 

I've used the coaxial input with my cd player with no issues. 

@sls883 My cd player does the same thing but with one click. Also, it clicks when I switch mode of inputs. Something is goofy here. Thank you for the response.
