4K HDMI Audio Extractor Splitter, 1080P@120Hz HDMI Audio Converter Adapter + Optical SPDIF + L/R Stereo HDMI2.0 HDCP2.2 Dolby Digital/DTS for Fire Stick, Blu-Ray Player

I recently started using my Dell G7 Gaming laptop to DJ with. Being a Windows machine, it has been a journey to learn how to get the best performance for delivering the best and most stable audio performance using Serato DJ Pro. But I noticed when I ran iTunes playlists or other sounds out of the headphone jack into the aux on my DJ board that there was a humming buzz sound I had not noticed before. Had a fantastic support call with Dell technicians who shared with me that the best sound source within my laptop was actually the NDVIA graphics card's "HDMI Audio" and suggested I try an HDMI audio extractor device to get the best audio, far superior than that which the headphone jack on my laptop was able to deliver. I purchased this one from avedio links and tried to use it connected to my 4k monitor and no "HDMI audio" source came up in my Windows settings. I reached out to avedio links for support and they explained to me that the only way I can get "HDMI audio" to come up as a sound output option from my laptop was to plug the HDMI cable into either a television or a monitor with built-in speakers. I thought it couldn't hurt with Amazon Prime's easy return process to go ahead and buy a 27" flatscreen monitor with speakers, I chose the "SANSUI Monitor 27 Inch IPS 100Hz Computer Monitor, USB-C FHD HDR Built-in Speakers" (and so far, I really like it). Sure enough, "HDMI Audio" because a sound source option in Windows. So I first hooked up my DJ speakers to the stereo output jack on the monitor, and the sound was good, but noticed when I opened up more than one application, unwanted noise would enter the sound. But then I inserted this avedio links HDMI Audio Extractor Splitter, then connected my DJ speakers to the sound output from the splitter, and yes, my tech support friend at Dell was absolutely correct: I finally achieved superb sound output from my computer! I played Billie Eilish "What Was I Made For" because there's plenty of quiet space in that song and her unearthly pure vocals were at least for me a ready-made audio benchmark test for high fidelity audio. And yes, not only was it the best sound I ever experienced coming out of my latpop computer into my DJ speakers, but when I paused the recording, turned the speakers way up along with the computer volume, amazing, amazing, hell yes, finally, no buzz, no hum, ready go from zero noise to Rave Dance Hall Jammin Powerhouse volume, all because I discovered HDMI Sound using a good, high quality HDMI Audio Spliter, and I'm very pleased that avedio links delivered just what I desired in tapping into the full breathtaking sound my NVIDIA graphics card has been waiting to deliver, and grateful for both Dell Computers and avedio links support for helping me to get there!

The only one I found that works to split left and right chain a lot of an HDMI signal properly.

Wow!! This device has saved the day and has saved me hundreds of dollars in unnecessary A/V receiver upgrades. I have an old Denon receiver that still works great and I’ve been wanting to cut the cable chord forever that my receiver requires old audio connections (red white left & right) in order to get 5.1 surround. I plugged in a Xumo box to this audio extractor and solved my surround sound issue from this video source. It’s well built and feels super sturdy. Highly recommend this audio extractor splitter.

I was wondering why my HP monitor with built-in audio would not work with a Sony Blu-ray player meant for TVs. When I hooked the Avedio 4K HDMI splitter between Blu-ray player and monitor and worked perfectly after I set it to CH2. Also verified that the monitor didn't work without the splitter which means that the HDMI audio was reformatted for the monitor. My monitor has audio inputs but those weren't needed as the monitor decoded the HDMI input automatically. Actually, worked better than expected since I didn't need to use the audio outputs from the splitter as I was expecting. I did try the audio outputs from the splitter to drive headphones which worked but the output was a little low. I expect that audio outputs would work with a Bluetooth device, but I haven't tried that yet. My only complaint is that the documentation was sketchy which only identified the ports and switches with no technical explanation.

Fantastic I love these things

Product arrived with no cables even though it said to only use the power cable provided . Their instruction pamphlet was written in every language known to man, except the one written in English was not done well and extremely confusing. This item will be returned.

I've tested this with two units now, and both of them have problems with the TOSLink SPDIF output. The signal from the L&R RCA connectors is fine (I'm inputting 2ch 24bit 48KHz PCM on the HDMI connector, which is well within spec for both HDMI and SPDIF), but the optical output is broken up & audibly distorted. You can even SEE the LED light inside flickering (which shouldn't be visible). Using known good optical cables, that work fine with other boxes. I'm disappointed; the latency was nice & low and the quality was great for audio coming out the analog connectors, but I need to be using the SPDIF output specifically for chassis ground isolation (to keep DC noise from propagating between the HDMI side of my system and the audio mixing side). Guess I'll have to try another brand; hopefully they don't all use the same chipset.

Just as expected and extremely easy to set up ....

I needed this device to connect my Firestick to a projector and surround sound system, and it was exactly what I needed. It’s been working perfectly and was delivered quickly and easily!

This product is amazing! After trying several alterative and considerably more expensive options - which didn't work - this unit delivered flawless performance and synchronisation at a fantastic price point so I would highly recommend. If you require 5.1 Dolby audio from a laptop (which in general don't have the required outputs), this is probably the easiest and cheapest solution. Obvious in and out on the HDMI line and then use an optical cable to connect your preferred decoder / amplifier, it even has a stereo mixdown additional output so it literally does everything. Installed mine in a 4k home cinema with Sony projector and Denon surround sound unit - it’s literally better than going to my local Odeon!

It is great alternative for older version, had been using it till now and there are no problems whatsoever. It has a nice compact design and doesn't have any heating problems. Flawlessly performs all functions like picture quality and most importantly it transmits Dolby sond effects to my hime theater for which I basically bought it. So I would say one should go for it.

Working perfectly optical in to hdmi out audio with 5.1 track. I have only one issue front center track and front left track is swaped audio But i resolved by re arange speaker cable,

Ce produit fonctionne parfaitement. branché derriere une Nvidia Shield pro il sépare bien le son pour mon ampli HC sans HDMI sur la sortie Spidf L'image transmise est sans problème que ce soit sur ma TV Oled 4k ou mon vidéoprojecteur. Le son en 5+1 décodé est de bonne qualité. j'enlève 1 étoile car il n'est que HDMI 1.4 et non 2.0. Donc pas compatible HDR10.
