ok, after twice sending back my NAD for serious noise from the 4 atmos speakers, I got a brand new one, VERY happy!
Now I'm probably getting old: I don't manage to play the Atmos channels, re-read the manual twice, and I have no idea what I'm doing wrong. I feel so stupid now. I disabled Dirac for the time being.
My configuration is 7.1.4, I checked all connections and I'm quite convinced they're ok. To be sure, I show some photos here:
Sorry for the reflections but it's readable. I'm still not sure about the Height1/2 configurations, I tried several ones but that didn't make any change.
I'm playing an Atmos test file from Dolby through Kodi, passthrough enabled in System Settings and also in settings of the current playing atmos file (I've played this test file successfully before).
Further settings in KODI: 2 channels, throughput device: NAD directplay or Wasabi... doesn't make a difference.
Look at printscreen of the IOS app - 3/2.1 means it doesn't see the height channels?
The crazy thing is... when I test back channels or height channels throught the Dolby Atmos test 7.1.4 file, it plays simultaneously surround left and front left.
NAD Display shows Dolby Digital instead of Atmos, so doesn't see the height channels. FYI I used this HTPC setup before for playing atmos, I also tried Fire TV 4K, but display says "Dolby Digital Plus" instead of Atmos.
I disabled and enabled A/V presets and listening modes.
I tried setting heights to TOP front and back as well
Any help would be much appreciated.
