Intermittently noise along playback a while after remote APP running

Hope I could find some enlightment here.
My setup is Mac mini late 2014 model, Audirvana 3.5, iPhone remote APP. I can’t even recall exactly since when this issue emerged. As long as I don’t open the remote APP, everyting is fine (btw I use my TV as Mac Mini’s monitor and Apple’s physical remote to control playback).
But as long as I open remote APP for just a while (say less than 1 min), even though I don’t do anything on the remote app, the music playback will be interfered by an intermittently noise, and then both desktop and phone APPs lose response to any operation, i.e. unable to pause, stop, skip track… I have to force quit the program on Mac.
Anyone can offer some ideas about how to fix this issue?
Thanks a lot in advance!

Hi @van_de_biau,

Can you send us a copy of the “Debug Info” when you have this issue? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

@Antoine Thanks. Below is the debug info just after Audirvana was force quit and relaunched:

We can see that nothing is synced with the software, how do you play your tracks if they are not synced with Audirvāna ?

I don’t let Audirvana monitor my music folder. So I don’t have library, not to mention synchronizing it…
Every time I want to play files I just click the icon left to the speaker icon on the bottom right of the window, supposedly play queue? and then drag the files there and release my mouse. Then I can play them.
Actually I play files in this manner since day 1 I used Audirvana and the remote app worked well for quite a long time until this issue happened and persisted to this day.

Ok, I tried to reproduce your issue with the same way of using the app without being able to reproduce it. Do you have the same issue if you have Built-In output selected instead of your OPPO?

I had this issue with the previous DAC too. I just replaced that one with Oppo hoping to detect the source of this problem.
I tested using built-in output and got the same issue.
Thank you.

Can you try with Audirvāna Origin or Audirvāna Studio if you have the same issue?
