VPFET HDMI Audio Extractor 4K HDMI to Optical 3.5mm AUX Audio Adapter Splitter Converter Support HDCP Digital DTS 5.1 PCM

Good Product. For a projector, monitor, or other device that does not include speakers, you'll need to purchase and EDID Emulator, otherwise sound will be disabled. Make sure this device matches the specs required. This is only for 4K/30MHz. If you need 4K/60 MHz, choose the other model (same brand), otherwise resolution will be limited. I used it to connect a a 4K Fire TV Stick to my projector, while routing sound to my receiver.

Very easy to set up and use. Good quality audio through the optical cable.

Only had it for a month but works on my ps5 well, no issues so far

I bought this since the XBox Series X doesn't have a built-in TOSLINK port (thanks, Phil). Unfortunately, while the device clearly physically supports 4k and DTS Digital, with the XBox I have to choose one or the other. With the audio selector switch in "Pass" and an optical cable connected to my Denon receiver, the XBox detects (incorrectly) that only stereo out is supported (no surround sound), but it will output a 4k signal to my projector. When I shift the selector switch to the manual 5.1 position, the XBox now offers Dolby and DTS Digital Surround options, both of which work with my receiver and sound amazing, but the video resolution drops to 1080p. There's still an option to switch to 4k, and it works (projector detects and displays a 4k input signal), but when I click the "Keep" button to maintain that resolution everything shifts back to 1080p, and the XBox "Video Info" dialog incorrectly reports that my display doesn't support 4k at either 60 or 120 Hz. To be fair, the root causes here are typical Microsoft arrogance: saving maybe a buck per console by dropping a port that most customers never use (but that they supported on the 360 and XBox One, and for which a lot of gaming-specific accessories (headphones) exist), and then failing to provide a manual "Trust me, I want DTS output" option when their auto-detection fails. And I can't think it's anything but a bug that the Series X will let me select, and correctly display, a 4k resolution, but then insist that it's unsupported and auto-shift back. However, I think there's also a flaw in the way VPFET implements the audio EDIDs; when the selector switch is in PASS the extractor doesn't correctly report capabilities of the downstream optical device, while when it's in 5.1" option it doesn't correctly report capabilities of the downstream video device. There may well be a technical reason for the former (I'm not an S/PDIF expert), but the latter is surely avoidable: either overwrite just the audio portion of the EDID coming from the downstream display (leaving the supported resolutions intact), or simulate some maximally-capable UHD device. Whatever they are reporting when the switch is in 5.1 clearly isn't satisfactory for some game consoles. Anyway, aside from this the device works great, even with other 4k sources, but I wanted to put a warning out there for anyone thinking of connecting it to an XBox that you may want to go with one of the more expensive name brands with verified support.

I run a decent, budget projector in a spare room and wanted to upgrade the audio. Projector has no digital audio out to run to my sound bar, this allowed me to run a toslink cable and push dolby digital surround to my sound system. Nice little bonus is it received power from the Firestick so I didn't need to run the extra usb power cord. This is able to push a signal through a 25ft toslink cable. No impact on video quality, sound quality is great. Awesome little gadget!

Old tv + new sound bar was a challenge! Hooked this little sound amplifier (which I lovingly call “gizmo”) up to the soundbar using an 3.5mm av cord (not included) and HDMI (1x included) to the AppleTV (which hooked up to a second HDMI to the tv) and it worked absolutely perfectly!! Literally took me 5 min to install. Had to look up what setting to have this gizmo set at and learned “PASS” was neutral for sound. I immediately ordered another gizmo for my folks who have the same issue hooking up a soundbar but to a new tv. I’m hoping they too find the same result.

Bought this for my monitor that doesn't have a headphone jack and while its easy to connect and does extract audio from the monitor and out to my old stereo receiver it wont let my monitor put out 1440p 120 hz anymore it only lets me choose 1080p 120 hz or 1440p 60hz.

I needed a way to connect a low-end 4k tv to my sound system. The tv has a way to connect via bluetooth but no way to connect via fiber optic cable. I ordered this device and it solved my issue (kinda). I will chalk it up to my own ignorance for the most part but I was not able to use this device as an adapter or a converter directly through the device itself. I'm unsure if it's due to product incompatibility with the tv (un55du6900fxza) or if I simply do not know how to properly hook it up. Thanks to someone else's review with labeled photo I was able to get it to work through my cable box. so if I want to play a gaming console or cast through my phone, I'd be stuck using the bluetooth function on the speaker that I'd rather not use. I do not feel that the instructions are as thorough as I would like. The instructions a too concise. But that is a nitpick at best and the device does work.
