4K 60Hz HDMI Audio Extractor Converter SPDIF + 3.5MM Output Supports HDMI 2.0, HDCP 2.2, 1080P@120Hz, 1080P@144Hz, Dolby Digital/DTS Passthrough CEC, HDR10 by J-Tech Digital [JTD18G-H5CH]

This review receives 5 Stars because I was able to utilize the RCA stereo output to supply my Sennheiser audio headset with a usable signal and that is why I bought the "box". I received the J-Tech Digital Premium Quality HDMI 2.1CH/5.1CH Audio Extractor, Model JTDAT5CH/JTD-ID:80 in a soft side mailing envelope along with two HDMI cables I ordered to connect the "box" with. Connecting was simple with the Roku Ultra HDMI output, connecting the Roku out to the "box" in, "box" out to my Onkyo AV receiver, Streaming Box HDMI #3 connection in. The "box" RCA connections were made from the "box" to the AV Analog In #4 RCA in connections. I plugged in the "box" power supply into an electrical outlet, then plugged in the power supply connection into the "box" power supply. The red light on the "box" turned on. I then selected ROKU on the AV receiver, which already was set up to "turn on" the system (TV, AV Rec, Roku) to view audio/video from the Roku through the AV receiver and on to the TV. I confirmed that audio was normal through the AV receiver out to the speakers as usual. The video came on at the TV as usual. I turned on the Sennheiser headset, put it on and did not hear any audio. I selected on the AV receiver the Satellite reception and sound came through the AV receiver system and also into my headset - normal. I reselected Roku and within a couple of seconds, audio and video from the Roku came on through the AV receiver but not through the headset. I tell you all this just to remind you to make sure you understand how a AV receiver works. I should have thought about this prior to connecting the "box". My Onkyo has Zone 2 and that is what outputs audio to my headset. I had failed to understand and set up Zone 2 for my Roku. I went into the Setup of the Onkyo, went into Input/Output menu and selected Analog output to the proper output to match the HDMI input - Streaming Box #3 HDMI with Analog #4 output. I then selected Zone 2 to Streaming Box and sound turned on in my headset. So, the box worked. Then, I checked the position of the switch, Bypass, 2CH Stereo, 5.1CH and it was selected to 5.1CH. I thought that can't be, RCA outputting 5.1?? I selected 2CH stereo and both the audio and video turned off. After a couple of seconds, both the audio and video came back on. Video looked good but audio seemed the same as before but what could I tell - I was listening to 2 channel stereo - I think. I selected Bypass on the switch and the audio/video turned off and after a couple of seconds came back on. Video seemed the same, audio also. No matter where I put the switch it seemed that nothing changed on audio or video. I left the switch in Bypass, headset playing audio and the AV receiver providing sound and the TV playing video. Well, okay I get what I want - audio through the headset and Roku seems to be good. And, I learned some more about my Onkyo AV receiver. The "box" and cables were delivered within the two days provided by Prime, in a large padded envelope, in a new package and I used the two new 18" HDMI cables to plug in the "box". I recommend buying the "box" because it gives me headset audio and still allows audio to be passed on to the AV receiver as though nothing changed. One thing I have not done is to check the audio programming when streaming a movie from either Netflix or Amazon through the "box" to check the AV receiver decoding Dolby. If that works I will not be updating this review. If it doesn't work - I will update the review to provide those comments. Good Luck - the box seems to be "plug -n-play".

I'm using this device to get TV Audio to my SONOS PLAYBAR, and my review focuses on this application.Many folks have written about problems in getting Dolby Digital or ANY sound from their TV when connecting the TV's optical out to the PLAYBAR. Some TV's have no optical out, some have no sound from their optical out when using an HDMI source, and some others send only stereo to the optical out. See this link for a list of TVs and their level of Playbar compatibility:sonos.custhelp.com/app/answers/detail/a_id/1931/~/television-compatibility-with-the-playbarA very simple, fairly inexpensive solution to such problems when setting up a Playbar, and one which has been working extremely well for me, is this J-Tech HDMI Audio extractor combined with a vanilla hdmi switch. (monoprice has a 4x1 hdmi switch for $24 OR an 8x1 switch for $79, and amazon has some good alternatives as well),Note that this solution will work even for TVs which are said to be incompatible at the Sonos link above, including those for which Sonos says there's no workaround. My TV is one of those. It's a pioneer elite, and I've yet to find one I'd want to replace it with. But my Sonos, Elite and JTech are working perfectly together, since an HDMI audio extractor (such as this JTech) completely eliminates the need for the TV's digital audio output port.This solution is ideal for folks, like myself, who are already using an HDMI switch or an hdmi switching AV Receiver (in these cases you'd only need to buy this J-Tech extractor), but even if you have to buy an HMDI switch, this approach has some advantages over an integrated hdmi/optical switch: It works for sources that have no digital audio output ports (ie, for sources that send audio only thru their hdmi ports, such as the Roku3); It's easier to find a switch handling ANY number of sources or matrix switching; It's less expensive; And you need to run only 1 cable (just an hdmi cable) from your equipment location to the TV location. Also note that, using a standalone switch, rather than TV switching, makes it much easier to add more sources at any time in the future, especially when you have cables behind walls or under the floor, or when you want to add more sources than the TV can handle.Here's how you set it up:- Plug your switcher's HDMI-out cable into the JTech's HDMI-in port (instead of the TV).- Connect a second HDMI cable from the JTech's HDMI-out to your TV's HMDI-in.- Connect the JTech's optical out to the Playbar.- Choose Digital Out on the JTech and you're done.(You'd locate the JTech near the TV and Playbar, avoiding the need to run the optical cable from the switch, or equipment location, to the tv location)I'm getting dolby digital whenever my source has dolby digital, and stereo whenever my source has stereo. My picture quality and audio are excellent, and video audio sync is perfect. No problems of any kind.(Note however that, as with every other device I've seen, this unit does not convert dolby digital plus to either vanilla DD or to stereo for the digital out. If you're getting DD+ you'd have to switch that off at the source. An example of this is Netflix whose surround sound is DD+ on Roku. Because of that, I have Roku set up to give me stereo from Netflix and DD 5.1 from Amazon. )Hope this helps
