It definitely does something different, but i have no idea how to progress.
Do you want me to apply the hotfix again ?

65

@sam_nazarko any hints?

66

Hi

So DTS: X works, just Atmos has problems?
Please try and apply the hotfix.

Sam

67

Hi Sam

Correct.

Logs from playing ā€œhelicopterā€ then dts-x gravity before hotfix:
https://paste.osmc.tv/uvilaneyiq

Same thing after hotfix:
First helicopter, then dts-x gravity.
Dts-x still works, atmos is trnasmitted as truehd.

Could it be related to this : Issue with DTS-HD and Vero4K - #91 by sam_nazarko
Denon and Marantz are essentially the same.

Someone with same generation reciever and kodi with the same problem as me:

@sam_nazarko
Do you think my vero is broken ? Or ?
I still get random distortion if i change audio device to HDMI.

70

I donā€™t think your device is faulty. If it was, we would see issues manifest in other ways.

It may be related to the Denon issue. Iā€™m looking in to this

You need HDMI selected (not PCM) for audio to work properly

Sam

71

If i change it away from Analog/Default on this screen Iā€™ll get distortion at random times.
Passtrough works when settings is as above, except for atmos that is.

72

You wonā€™t get passthrough to work properly when PCM is enabled.

Do you get distortion on HDMI from a fresh boot? Is stereo upmixing disabled?

This is what needs to be tackled first

Sam

73

Hi again @sam_nazarko
Thanks for the ongoing support - i appreciate how annoying customers are :wink:

I havenā€™t had that happen yet.
It usually happens when the sound mode changes, but at random times. Sometimes when starting playback, sometimes when stopping playback. Yesterday it happened when i switched ā€œaudio output deviceā€ to HDMI, which usually doesnā€™t trigger the distortion.

yes.

Can you expand on this ?
It seems counterintuitive that ā€œAudio output deviceā€ affects/overrides the ā€œpasstrough output deviceā€ which is set to HDMI, and disabled (like in this screenshot: https://imgur.com/FvSsdnO)
It also seems weird that dts:x would work with the wrong config, and truehd wouldnā€™t.

75

Not at all.

For now, disabling stereo upmixing will probably resolve this.
We are aware of this problem, although it only affects a small number of users which is making it hard to diagnose.

Sam

76

It is disabled. Should i enable, then disable it ? Or did you mean enable it ?
I donā€™t even have upmixing enabled on the reciever.

77

Thanks for clarifying. Itā€™s best to keep it disabled.

Weā€™re aware of a distortion at random times with the latest audio improvements; but weā€™re not sure why this is happening yet, or what the resolution is.

Weā€™re working on this however.
