HDMI 2.0 Audio Extractor 4K 60Hz PS5 1080P 120Hz 4:4:4 HDCP 2.2 CEC D-olby vision HDR de-embed SPDIF Optical 5.1CH 3.5mm stereo L/R Audio Breakout D-olby Digital Audio Decoder EDID Management Scaler

I bought to split the stereo PCM audio from a Firestick 4K, mainly to allow me to use Disney+ with a PC monitor (since they currently limit streams to 720p on Windows computers). This means this review won't touch on either the ability of the device to handle 5.1 channel audio or how the device functions as a scaler. I also have a 60fps 1080p non-HDR display, so I can't comment on HDR or >60fps performance.I have the device set up to connect to a dedicated DAC via the Optical SPDIF output.It can play both Disney+ and Amazon Prime Video without and HDCP errors, and they both load 1080p with no apparent degradation to the video quality. For my use case, copy protection was the biggest barrier, so I'm happy to report that I've had no issues with the switches on the unit left to the default position.Since I'm using a digital optical connection, the resulting audio output should be 'bit perfect' to what is coming out of the HDMI connection. I'm not sure if the device does any processing to that signal that could affect quality. Watching a film to test the audio quality, I did find the audio a bit sibilant (i.e. harsh 'ess' sounds), but playing the same movie through a different source, I believe that's just a matter of the film's audio mix. Bass and soundstage seemed present, and there were no distortions that I could hear that weren't present when played through another source too. So I'd say the audio's being played pretty much untouched.I also tested the stereo 3.5mm output by plugging earphones directly into it. This isn't a sensible way to use the device either way, since the volume isn't adjustable. Doing this with my DAC (which doesn't have an amp built-in either) gives perfectly reasonable sound quality. But through this HDMI audio splitter, the audio was tinny and lifeless. This may be an issue of the power being insufficent to drive the earphones without amplification, resulting in no bass. Plugging the stereo output through an amp instead seemed to give much better results. Since the volume levels are inherently going to vary a bit when you change the audio chain, it's a bit hard to give comparisons to the optical-to-dac-to-amp output vs stereo-to-amp, but I'd say dialog felt much pushed forward and perhaps flatter. This may just have been a volume issue, but it felt like using the optical output to my DAC gave higher quality results. But it was definitely perfectly usable still.I would have liked to have had the option for coaxial output as well. But the comparable devices with this feature are more expensive, or like many of the audio splitters on Amazon, seem to lack any HDCP decoding which would make it useless for certain kinds of copy-protected content.The unit also runs moderately warm. Not 'burn you' hot, but warmer than my DAC, amp, or Firestick got to the touch when running for the same time. This shouldn't be an issue, but I suppose it could potentially get overly hot if you let it running for long enough at a time.Audio and visual quality can be really subjective (audio in particular can sound drastically different in bass, clarity, and soundstage just by a matter of volume), and is obviously affected by the quality of the source content. But as best as I can tell, this device does exactly what it says it does. Splits the audio from the HDMI to analog stereo 3.5mm or digital optical SPDIF, with no alteration to either the quality of the picture or the quality of the audio.So for those that want something that can do that, I can recommend this product.

HDMI 2.0 audio splitter - Got 5.1 surround on optical using Fire TV stick, when audio set to "Dolby Digital always".Note: this audio splitter does not down-convert Dolby Digital Plus to plain Dolby Digital, so you will need a device that is capable of outputting Dolby Digital, such as a Fire TV stick. (not the "Lite" version which only does passthrough - other models should work).Using a NowTV box (rebranded Roku) I could only get stereo, as most Roku boxes only do digital passthrough, not dolby decoding, so can't convert Dolby Digital Plus to Dolby Digital.Panasonic BluRay player worked fine - got 5.1 with no changes.EDID switches set to ON,OFF,OFF,ON,ON.

Bought this product on recommendation from someone on YouTube and they dubbed it a swiss army knife for HDMI or something along them lines.I bought this just to see if it could solve a crazy issue I had.Have a great Panasonic GH2 camera which gives a live HDMI feed to a monitor/tv just fine. but would refuse to output anything to any capture cards I owned. sounds crazy but I think Panasonic put darn HDCP or at very least some weird EDID on the GH2 which stops capture cards working.Well this little adapter fixes that. plunged in line and powered from the USB port on the computer and with a bit of playing about with the dip switches I was able to get the camera to work fine. its annoying that I have to resort to this but it has yet to fail me so I am happy and it saved me buying a brand new camera just to get a HDMI feed for webcam purposesIt does pass through the audio but did not test the extraction ability of it. but worked great for my specific use case

Seems to be ok however it did not work well enofor my use case so returned it.

After my initial set up I wasn't impressed with this after picture quality was extremely poor as was the audio.The seller contacted me about this and offered me a second unit to test.At first it was a similar story with the second unit but after a couple of hours playing about with setting all is well and unit works perfectly.The problem was with display setting with a firestick.For this to work you have to go into display settings and change the 'dynamic range settings' this needs to be set to either 'adaptive' or 'disable HDR'.I set mine to 'adaptive' and set the unit to 4k/Atmos, it shows you on the unit how to set, its straightforward.After I got everything set correctly my picture quality on my tv is now 4 2160p UHD and audio is now Dolby Atmos.So now given 5 stars to seller for customer service and would certainly deal with again.

It did do the job it was designed for, and finally allowed me to get 7.1 out of my PC to my screen, just so it could send it back through eArc.However, the usb connection is bad, and it frequently blanks or flickers if a mouse farts near it, so I guess the quality is not so good. I would have returned it, but I've never returned anything in my life.

Brought this HDMI 2.1 audio splitter for my Xbox Series X as I was experiencing an audio delay when outputting to my Sonos Playbar over an optical connection from my TV. This was really frustrating as the audio was behind the video, even when the audio delay on the TV/Sonos Playbar was set to 0. After installing this device between the Xbox, TV - Sonos Playbar, I'm glad to say the audio is now in perfect sync. There is no drop in quality from the 4K 120hz video coming from the Xbox to the TV, and it continues to output with HDR10 enabled. Really easy to install, as well as selecting the correct video/audio output you want (5.1, 7.1) by simply pressing a button to cycle through options. Build quality is good and feels like a sturdy bit of kit which will last. Whilst it is a little expensive, this device does exactly what I needed it to do. If your a stickler for perfection, this is the device you need to fix the audio sync issues, whilst still enjoying HDMI 2.1 video quality.
