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.

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.

This item work exactly as described. It has allowed me to use my xumo stream box with an extra computer monitor and speaker set for an extremely clutter-free bedroom.

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.

Works for my hdmi to hdmi set up as normal, but didn’t work for my hdmi to DVI set up (which most folks probably don’t have anyway). FYI

Great device. Did not work on my electronics. Returned

I was using this to split the audio from the HDMI to a sound system. The sound came out fine through the audio system. The problem I had was the passthrough of the HDMI Video signal was bad when using the video from the adapter. It definitely splits the audio and that part works as advertised.

My AV receiver does not generate 5.1 channel sound from the HDMI input: it requires the audio input via optical connector. My Roku does not have an optical audio out. So I plug my Roku into this device and feed the optical audio to the AV receiver and the video to my projector. Works extremely well.
