I have noticed after playing music or movies; for example 5.1 material; when clicking stop - there comes a pop in the sound (audio sent over HDMI direct throughput). I have multiple other devices including an Apple Mac Mini running Windows10 and Kodi were this is not a problem; no problem on Apple TV 4K or multiple blu-ray players.
Audio processed by Marantz AV8802a.
Is your connection
When I use option 2 (optical) I sometimes get pop/scratch sound after a movie ends. With option 3 I don’t get that. My 20 year old Yamaha doesn’t have HDMI input 
Do you have Passthrough enabled?
@grahamh – I think I have a fix for this in kernel. We can discuss it soon.
@tor.gunnar.berland – can you see if you can narrow it down to a specific format or specific switch between formats?
We want to release an update on Sunday, so we won’t be able to make any improvements before then; but we can start after this point.

It’s a difficult one to track down because different receivers/TVs are better/worse at hiding mode switches. I have a cunning plan, though.
Vero => HDMI => Marantz => HDMI => TV
I noticed this on DD+ 5.1; I can check on others as well.
Thanks. Can you confirm this is using passthrough and the receiver is getting DD+ (ie vero is not sending it PCM)?
Yes, we’ve never had pops on optical or analogue. AFAIK
I use passthrough always, since most movies these days are Atmos or DTS:X (which works flawlessly by the way). And surround processor receives DD+.
Edit:
If I had received something other than DD+ on DD+ source; I would have reported this - not the popping I’m an audio geek; and pay really close attention to these things.
Edit2:
I have never heard pops on stop or start of audio stream on any other devices. Only Vero 4K
It seems to be applying to most formats (even a small one on start of audio stream). On DTS:X; ATMOS, DTS-HD.MA 5.1; TrueHD 5.1 (I could not hear anything here (TrueHD 5.1) - could be luck?).
The pop is not really load; one upon start of stream. And on stop I get a small pop; then 1/2 second later a new pop. On Marantz after stop; it indicates no audio is received. So this seems to be connected to going from nothing to something; and other way around. Other devices operate this way as well without any pops (my Mac Mini Later 2014 runs Kodi 17.6 on Windows 10; so same version of Kodi as we have on Vero 4K).
I set “keep audio device alive” setting to Always. Problem gone; not sure what this is doing - according to Marantz AV8802a; no audio is received when not playing off anything.
I don’t think anyone knows exactly what keep device alive does but it seems to hang on to the previous audio settings as a new track/clip starts so you can get a hiccup 5-10secs into the track. I think I have solved the pop issue and hoping we can test it and get it into this month’s update anyway.
After installing April update; this seems to be fixed even without keep audio device alive setting turned on.
