HDMI ARC to Optical Audio Adapter, 4K@60Hz HDMI Audio Splitter Converter, HDMI to HDMI + Optical Toslink SPDIF + 3.5mm Jack AUX Audio Out, Metal HDMI Audio Extractor Support Blue-Ray Play Soundbar

I was disappointed to see my New Samsung Smart TV did not have a SPDIF port for my Yamaha 5.1 channel sound system to connect to. I'm not ready to buy a new sound system. The one I have puts out great sound. Fortunately, this converter seamlessly connected my sound system to the HDMI ARC port on the TV. It works great! Now I have surround sound again when watching movies on my new tv.

My setup is an Nvidia Shield (2017 version) feeding a LG 4K OLED TV (CX series, 2020 version). My receiver is old and does not support 4K, so I cannot feed the HDMI directly thru my receiver. I have to feed it into the TV then use either Optical or HDMI ARC from the TV to feed audio back to my receiver. HOWEVER, LG no longer provides DTS support on their TVs, so all of my DTS content would not play sound.I placed this device between my Shield and LG TV, running the optical from this device to my receiver. Set the device to 5.1 (using the little 3-way switch on it). And it works!!! I get DTS, DD, AC3, etc all on my receiver just fine, while still passing the 4K@60 video (with HDR) onto my LG TV.So far, all of the video file formats I have sent through this setup work perfectly. Video is 4K@60, and it passes HDR and Dolby Vision. Optical is not supported to be able to handle DTS-HD, so I changed the settings in KODI to say that my receiver does not support DTS-HD and apparently it converts it down to regular DTS because files with DTS-HD audio also play just fine.I will report back if there are any file formats this does not work with, but so far so good!

Didn’t work. Passed video signal but not audio. Audio was just some out-of-control signal (was using optical) that burned out my receiver. Returning it, but wish I could get reimbursed for the damage. Causing problems rather than fixing them…

I have an old receiver which was quite high performance in its day. We have a fancy new large screen TV which is very "smart", but it is too far from our component stack to run optical cable. This little box allowed me to runa long HDMI from my screen with a very short optical cable from this box AND I can use that same HDMI cable to carry the signal from my BluRay player to my big screen! I thought I would need 2 cables, one to take the signal to the big screen and a separate ARC cable to take the sound from the TV to the speakers. I plugged all the cables in and it immediately worked!I am giving it 4 stars instead of 5 because I am glad I had a tiny optical cable available. The HDMI and optical connectors are too close together for most cables. My snazzy new 12 meter QVC HDMI cable has one of the slimmest connectors I have ever seen for HDMI, but still 2 out of my 3 optical cables would not fit. I don't have the brand or part number for the cable that works because I must have purchased it ten years ago. It has almost no jacket on the cable and very small ends (it's fiber, it doesn't need any shielding, I think the thick jackets on most optical cables are either to keep them from getting kinked or just to satisfy US consumers' misguided bias associating bulky size with high performance.)Also, the ARC on/off switch is not labelled! It just says on/off. I bought this box so I could stream movies using my smart TV so I always leave this switch in the ON position.It did work the first time I tried it. However, the next time I turned on my system, there was no sound from my TV. I tried turning the ARC switch off and back on, but that didn't help. Unplugging the HDMI from my BluRay player got things working so I was satisfied.Later, when I plugged the BluRay cable back in, things still worked fine. I played around for a while and concluded that it was this box that was getting confused, not my TV. If I turn on the BluRay player, the box will expect the signal to come from the BluRay's HDMI cable. I have to turn off my Receiver, and turn it back on to reset the box so it transmits the ARC signal from the TV. This solution may be somewhat unique to my configuration because my BluRay player is powered through an AC outlet on my receiver. When I turn off my receiver, the BluRay player is also powered down. However, when I turn on my receiver, the BluRay does not power up unless I manually turn it on.I also have HDMI-CEC turned on in both the BluRay player and the TV (Samsung AnyNet+). This box transmits CEC signals; I don't know if it responds to them.I looked at so many HDMI Audio Extractors and HDMI Switches with Audio Extractors, that I don' t know if it was mentioned in this specific unit, but I think that, by default, most of this type of unit will switch when a new source is detected. If I turn on the BluRay player it will switch from ARC to BluRay. However, when I turn off the BluRay player, the ARC still doesn't play. Also, I can turn the TV off and On, but still no sound. After using my BluRay player, I have to turn the Receiver off and on to coerce this little box to send the ARC signal from my TV to my surround system again.This is fine with me. I rarely use my BluRay player and turning off the receiver when I finish a movie is no hardship.PRO:-- It simply WORKS!!-- It is tiny!-- It has USB input so you don't even need to use the power brick. You can use any USB port nearby-- Using this box is way, way cheaper than purchasing an updated ReceiverCON-- The HDMI and Optical connectors are VERY close together. Look for cables with the narrowest connectors available.-- My unit does not have ARC printed above the ON/OFF switch-- Before you invite a crowd over to watch a movie with your new set up, give yourself some time to learn how powering on components in different sequences will effect the path of signals through this box.I like to space out my A/V purchases. I use whichever component as newest for streaming and control. I just bought a new Large Screen TV so now I use it for streaming and control. In a few years when I replace my BluRay player, I will use my TV as just a big, dumb screen -- like a monitor. I will use my BluRay player for streaming and control. A few years after that I might replace my Receiver or maybe get the latest Chromecast or Roku or Firestick or whatever new technology becomes available. This way I always get to use the latest technology, but I don't have to throw everything out with every generation.

Fairly easy to connect, does what it's supposed to do.

UPDATE -seems box is incapable of HDMI arc functions. Works great as HDMI pass through described below, but I was limited to passing audio to the single device attached to it.When I connected to the TV Arc output so I can pass audio from all devices connected direct to TV, the arc did not work with any settings to produce optical out. ARC works with my sound bar, but not this box. Arc on/off & switch settings for channels, nor setting PCM on the Tv worked. Returned to find one with working ARC support.Original review:Fantastic little metal box. My older Denon AVR will not read HDMI audio, so am reliant on optical. Unfortunately my TV only outputs PCM (2.1) on its optical, so was not getting full 5.1 sound on my AVR. Once I installed this guy, Dolby digital again shows on the AVR and I hear an INSTANT improvement in sound quality, and no loss of picture quality. Plugged Firestick directly into the box, and used the HDMI out to TV and optical to the AVR. 4K60 is also HDR working great. Also note with Netflix and HBO Max dolby digital+ on the optical port. Many of these converters have trouble with this as they cant handle Dolby digital+ on optical when set to 5.1 mode.-1 star for value: the supplied HDMI cable is technically working in 4K HDR, but is extremely cheap and has no markings. I tested but did not leave installed. Optical cable was fine and the inclusion of both and the power supply was a nice bonus.Was leaning toward a competing model by J-tecx, but too many complaints of defective units or early failure.

Used the spitter for the HDMI cord from my TV to the spitter for optical cord for my sound board,worked great !!
