please let me explain why , last month my receiver's hdmi input & output stopped correctly passing video but still handles audio

so i got a HDMI 2.1 Audio Extractor/Converter adapter for a go between my apple box,tv, & receiver

but iv struggled to find a good one that does my needs right my gear is


Apple TV 4K (3rd Generation) 128 GB Ethernet ver

tv - TCL 55-inch 6-Series 4K UHD Dolby Vision HDR QLED Roku Smart TV - 55R635

receiver - outlaw 4k 976

heres more info an context my first two attempts were a



OREI 8K HDMI Splitter 1 X 2, Duplicate with Audio Extractor

&

CORSAHD 4K@60Hz HDMI Audio Extractor & Converter , i should have googled on wither or not either could take apple tv's Dolby Vision & 5.1 LPCM in & correctly output Dolby Vision to the tv & 5.1 LPCM to my receiver ?

as neither did without growing issues.


lets start with the orei

after a lot of trail an error with the edid settings

i settled on mode 001 which gave the correct audio & video pass-threw & extract without messing with the Dolby vision colors when that content was played well for a while

now let my explain why i dont just use the copy mode because i did , the straight-up edid copy 111 worked but after a few hours on avg 4 to 6hrs with any app the audio

vi both hdmi port 2 & optical would just cut out regardless of the restarting the apple tv , receiver , or tv an wither i used the apples tv's any of the output modes



wither it be default lpcm or forced ac3 5.1 or 2.0 options , so i went with 001 which till now was fine but now the audio stays but the video cuts out after

about 8 to 10hs of use an strangely sooner when play anything from the disney+ app both issues for mode 111 & 001 are fixed by unplugging & re-plugging the orei

i have not used any of the other mode long term as all seemed to give the right audio in & out but would mess with frame , res , & color space format , they just generally f'ed the image.

now to the

the CORSAHD 4K@60Hz HDMI Audio Extractor & Converter
____________________________________________________


the edid setting that correctly passing Dolby vision , frame rate , res & color space (4.4.4.) does not correctly pass 5.1 lpcm or

5.1 ac3 as the center ch feed for lpcm is missing an for any 5.1ac3 track from any app or even if i set ac3 5.1 forced as default the center ch feed comes out the left ch

as the 5.1 alignment is off , i haven't tried forcing 2.0 ac3 as this has been a mass headache , right now im just using the mode the passes hdr an that works fine & with forced 2.0ac3

but the 5.1 center issues remain if i don't force 2.0ac3

so in need help finding a 4K@60Hz dolby vision/hdr & HDMI Audio Extractor & Converter under 100$ that has a EDID settings that supports & allow

5.1 LPCM & 5.1 ac3 in from the Apple TV 4K (3rd Generation) & to optical an or hdmi and simultaneously can correctly pass dolby vision/hdr at 60hz at 4.4.4

can someone help me with this ?



iv thought about trying the next tier up with the CORSAHD brand with the CO-HAE118 version as the current one iv been using has been

going 2 weeks straight 24/7 with no image cutout unlike the orei so ill give CORSAHD another shot , any according to the amazon ask question option it claims the it can

allow 5.1 LPCM & 5.1 ac3 in from the Apple TV 4K (3rd Generation) & to optical an or hdmi and simultaneously can correctly pass dolby vision/hdr at 60hz at 4.4.4

as were it wasn't sure that the ver i have could which i now can confirm it cant (fyi why didnt i try the next one up well i didnt see that item the first time i looked)

2. if the CO-HAE118 version cant , can someone suggest on one from a different brand that is confirmed to by able to

I tried a few extractors a few years ago, one being a professional-grade unit from Crestrom. Apparently they will only deliver 5.1 via the optical output. Give that a try if you haven't already.
