ViewHD UHD 18G HDMI Audio Extractor/Splitter Support HDMI v2.0 | HDCP v2.2 | 4K@60Hz | HDR | ARC | 3.5MM Analog Audio Output | Toslink Optical Audio Output | HDMI Audio Output | Model: VHD-UHAE2

I gotta say, I'm impressed! I bought this giving it a less than a 10% chance of actually doing what it said it would do. Boy was I surprised when it worked flawlessly out of the box.My equipment:Chromecast Ultra (CU)LG B6 65" OLEDDenon AVR-X4000 ReceiverThe problem:For many sources (like Netflix, Google Play Movies, HBO Go, etc), the Chromecast Ultra defaults to a Dolby Digital Plus (DD+) audio stream. Like many TVs, the LG OLED can't pass DD+ over HDMI ARC. The TV tells the Chromecast that it can't handle DD+ and the Chromecast degrades the audio all the way down to Stereo (not even just regular 5.1 DD, but 2 channel stereo)!The receiver will pass 4k, so I could have plugged the CU into the Denon, but the Denon won't pass HDR video (HDR10, Dolby Vision), so I would get better audio, but degraded video, sigh....The solution:This box (VHD-UHAE2). I did a lot of searching here and other sites for HDMI audio extractors, HDMI splitters with EDID management, etc. This appears to be the only box on the market with a reasonable price tag that will accomplish what I needed.I plugged the CU into the HDMI input, ran a cable from HDMI Out 1 on the box to the TV and a cable from HDMI Out 2 to the Denon. Bam, I have HDR video from the CU and DD+ to my receiver. All I did was set the EDID selector on the box to 7.1 and I was done. Testing was done streaming Wonder Woman in UHD via Vudu.Bonus - the wall wart to power this thing is actually really small. Think the form factor of a factory iPhone 6s charger, so it doesn't end up blocking multiple outlets when you plug it in.

I was having an issue with sending a signal from my computer to my TV through an audio receiver. The issue was that while the audio receiver would send a 4k 60hz signal through to the tv, it couldn't do this at chroma 4:4:4. Another issue was that when sending the signal through my defaulted native resolution showed up as being 1080p instead of the actual native res of 3840x2160. this caused issues in applications that were trying to scale. i could of course just plug it directly into the TV to solve this issue, but then i wouldn't be able to output the 5.1 sound from my receiver.This kind of problems is a hardware so not something that can really be fixed by any type of fiddling with settings or picking up some software fix to solve it. Searching over numerous ideas i ran across this audio extractor with an hdmi out. Honestly i wasn't expecting it to work, but it did have the neccessary output that i was looking for so i went for it. This thing works almost perfectly (see edit)sending the signal through it i am able to get the native res from my TV, add custom resolutions without issue, receive an accurate 4:4:4 signal, and all while outputting 5.1 channel sound to my stereo receiver. Set up was as simple as plugging everything in, selecting output 2 for the hdmi 720p black only Sound output and then turning on ARC. (Edit : arc was unnecessary)I'm really surprised by how well this works and if your looking for something for a similar purpose than i can't imagine it wouldn't work for you. I've only had this product set up for a few days so i can't speak to the longevity of it, but as long as it keeps working it is doing exactly what i need it to.EDIT: dropped to 3 stars due to a couple of issues. Sometimes on restarting my system the screen turns pink, unplugging/replugging fixes issue but it's a nuisance. Also when audio has valid hdmi signal but video doesn't there is audio popping/bad signal sent threw audio hdmi.These issues don't stop the product from working, but are annoying. I haven't been able to find another product that does what this does (mainly the hdmi audio out), so I'll be putting up with the annoyances for now. Honestly though, if these problems were fixed this would be a great product and if you don't mind dealing with them it does do what it's suppose to.

I recently upgraded my home entertainment center to support 4K HDR / HDCP 2.2 content. My previous setup only supported 4K, but no HDR, nor HDCP 2.2 (AMP did not supported it). So I upgraded my TV to OLED for awesome HDR, and had to upgrade AVR to support HDCP 2.2 (and later found out needed to support HDR as well even through it is passthrough). This worked great for about a month, but the new AVR decided that it did not want to output video anymore, so I had to go back to my old AVR during the long process of getting the new AVR warranty repaired. So I was back to square one of no HDR content (rec709 versus rec2020), or HDCP 2.2 content (Netflix from NVIDIA Shield) while repair was was being completed. Sure I could have used Netflix on the TV for 4K HDCP 2.2 content (then you have to add ARC and CEC back into the mix which does not work well for a multi input type environment). My NVIDIA Shield when playing 4K content that was rec2020 though an AVR that only supported rec709 the NVIDIA Shield would not convert the video colorspace to rec709, it pretty much only dropped bits and the output looked horrible.Long story... So I started searching for some other solution while AVR was out for warranty repair that gave me everything without a large expense. So I tried this HDMI Audio Extractor as an experiment. I did not have high hopes. Simple, HDMI in, ARC HDMI out to TV, Audio HDMI to old AVR, minor changes to my Logitech hub configuration to change the input on the TV. So now I am back to watching 4K HDR content, and copy protected HDCP 2.2 content. So easy. One extra bonus I was not expecting, my new AVR only supported 4K HDR content at 30Hz (before it decided not to work, still waiting on warranty repair), with this Audio Extractor in place, I get 4K HDR at 60Hz. So I may end up keeping this configuration, even though I paid way too much to support 4K HDR / HDCP 2.2 on new AVR, and just kept the old AVR around. The old AVR works fine now with this Audio Extractor in place.Update:Was 5 stars, but now it is 4. Over the last few weeks that I have been using this solution, I have had to reboot the device a few times. Seems it gets into a state where cannot recover. Before rebooting, I did unplug all devices and replug them back in, along with rebooting devices. Then I found the just rebooting the ViewHD made it come back.
