Bitstream not always working on Pi4

Hey, I'm a total beginner in libreelec and didnt found much about this topic

Here's my log: http://ix.io/4hiP

Its Pi4 -> Marantz SR7013 -> Sony XF90 TV

I didnt created a manual edid yet, but was powering on the Raspberry as last step. Sometimes in the main menu, the AVR isnt showing PCM, also I tried with Transformers 5 first. AC3 5.1 was bitstreamed (no PCM on AVR), when I changed to TrueHD it was PCM again. After that i tried some other movies but still had no luck to get it bitstreaming. I'm using a Argon One case and therefore normal sized HDMI ports if that plays a role, didnt tried without it as I dont have an adapter for micro HDMI

Please help

ok ... Looks like I had to activate the HD Audio Formats first. So after three days of figuring out what was worng, I solved it 1hour after finally posting into the forum.
