Actually that is repeatable all the time, any kind of powercycle or resync and then app needs to be launched again. So please make sure you have tested it that way.
finally, try to unplug/replug TX1 and restart APP, still no atmos ?
Also please confirm to which input you have ATV4K connected ? because on config there is no AUDIO and no video going to TX1, so that's normal you got no sound. (and actually you should have no video as well), so may be try TX0 to AVR first. Or may be config was exported before web and oled refreshed ?
the ATV4K audio format menu says "audio will be decoded and sent to your equipment as uncompressed multichannel LPCM". This is when atmos is set to "on", and this is what we get when playing titles.
Does WU appears as Atmos title when you have Vertex2 in the loop ?
Anyway, we will run more tests in next hours and update you again.
EDIT: Ok, we noticed when playing movie with atmos that it didn't come as atmos when it had just done so previously. we also noticed the image was blotchy
then we tried to reduce EDID to 1080p and got atmos right away. it seemed net speed affected what atv was giving out, so please try with 1080p full audio edid and see if you have same issue.
It's possible that when ATV is connected to your AVR directly, it sees that your AVR is limited to 300MHz max and no issue, while if you use custom EDID or automix with our devices ATV will see 600MHz capable and that can affect things because of network condition.
EDIT2: make sure you reboot ATV4K once connected to Vertex2
I have the ATV connected to input 2, and to clarify I restart all devices between changing settings (including restarting the ATV), I also toggle atoms on/off on the ATV.
So the netflix app is always restarted by default in my tests.
I tried the different options:
1. I connected the AVR to TX1 again and selected one of the custom EDID with 1080p (without HDR), I still get no Atmos.
2. I connected the AVR to TX0 and tried the custom 1080p (without HDR), no atmos, in this setting Atmos was also not available to choose in the ATV.
3. I also tried AVR to TX0 with "copy TX0 Sink" but with same result as the custom EDID.
In both cases when I connected the AVR to Tx0 I had the projector connected to TX1 (so I could get a picture), two odd observations is that when I have the AVR connected to Tx0 or Tx1 I loose picture every 5-10 seconds, in 2-3 sek the picture comes back, feel like some kind of sync issue, this never occurs when the AVR is connected to Audio out.
Also when selecting the custom 1080p EDID the ATV reports 720p (does not matter to me just whant to give the info). I attach the both configs when connecting the AVR to Tx0 if this can help.
Also regaring the question about Atmos reporting from ATV when vertex is in the loop, yes in the usual configs i use (using audio out connection), ATV shows WU as atmos and all other sounds in the menu of the ATV has sound(pcm 2.0) and I can play 5.1 movies but as soon as i start an Atmos title the sound signal is "none"
It is quite annoying since I bought the vertex2 to get HDR from my sources (as my current HDMI board in the storm audio does not support this), but with the vertex2 HDR works fine but Atmos not
