Tendak HDMI Audio Extractor, 4K 30Hz HDMI Audio Splitter to Optical TOSLINK SPDIF + 3.5mm Stereo Audio Adapter, Compatable for TV, PC, PS3/4/5, Blu-ray/DVD/HD Player

I'm glad I found this, now I can play my blue ray movies and able to run my av receiver that doesn't have HDMI and have that true 5.1 surround sound!

My wife has hearing issues so she wears Sennheiser wireless headphones when we watch TV while I don't. If she is watching alone it is nice if she can mute the sound from our AV receiver and then listen with her headphones. Otherwise, I can hear it all over the house. I struggled to find a way to connect the headphones so we could watch our DirecTV, Roku, and Blue Ray in this manner. I called Sennheiser and they were no help at all. I searched the web and found a lot of discussion about this problem but no solutions. After a lot of research I worked out a method using these Tendak boxes between the HDMI sources (Roku, etc.) and the AV receiver. This allows me to mute the sound at the AV receiver and still hear with the headphones that have their own volume control. I route the sound output through a 4-port audio switch to the headphones. I just connected it all together today and it works great. Having to switch the audio switch box manually is a minor inconvenience. The Tendak boxes came with RCA to 3.5mm cables (which I needed) and micro USB power cables (which I didn't need). I keep the boxes switched to 2-chan and have not had any problem. The sound from all of my sources comes to the headphones just fine. Other competing boxes seemed to indicate that 5.1 sound would not be converted to 2-chan. In the question section the seller said that the Tendak would convert to 2-chan. I can't tell if my sources are sending 5.1 sound or not (I assume they are). All I know is that it works. Thanks Tendak.Update 11/30/2016: I found that some Roku channels (HBO Now for one) send audio in a format that the Tendak box cannot decode. So, no audio from those channels. I went in to the Roku setup and changed the output to 2 channel stereo. Now the headphones are working with all Roku channels but my home theater sound is not as good. I will live with it for now and see if it bothers me.

I bought this Tendak TOSLINK splitter to see if I could get some more use out of my old audio equipment. They predate the adoption of HDMI as a standard, so optical is my only option. No sense in spending money to upgrade to the latest tech if a simple adapter like this could work. Sure enough, it did.The Boston Acoustics TVee One is now hooked up to our Windows PC and sounding much better than the monitor's speaker.

I am giving this 5 stars as it works exactly as it should, but, not for my purposes so it was returned. The product 100% extracted the audio and passed a full signal to all the two connected devices, however, I had wanted this to be able to connect to my TV and to my home theater receiver in order to get the audio into my receiver in 5.1 surround yet still have stereo input to my TV for times that I did not want to use the receiver (which is most of the time in my household unless I am the one watching something, everyone else in the house is fine with stereo and the TV speakers). I was unable to make this device work to do that in the fashion I needed.The AppleTV4 is just too smart. It senses what devices are connected via HDMI and then adjusts the output from the ATV4 to accommodate. Since the only device that is connected via HDMI using this product is the TV, the ATV4 downgrades all the audio to stereo, so all I get to the receiver is stereo as well, no 5.1 at all (and, yes, I tried all the modes).My receiver has pass-through mode which works, but, everyone in the household complains about all the buttons required to get sound to the TV using that method (change TV input to receiver, then change AV input to the HDMI in from the Apple TV). For many of us these few keystrokes are not a problem but for my household they want to turn on the TV, switch the input to the HDMI for the ATV4 and then be done with no receiver remote involved. This won't help you with that for reasons shown.Perhaps some newer TVs have full 5.1 processing capability but my Panasonic Plasma does not, so, the issues I stated could not be overcome with this product. If your TV will receive a full 5.1 signal and process it perhaps your experience will be different.

I have the 2021 Roku ultra and I have tried 2 different audio hdmi extractors with less than great results. This one will randomly flicker horizontal lines across the screen. It's not that bad, but it's far from perfect. It's most visible on dark scenes with movement, and it only sometimes happens.I thought maybe it was the cables so I switched out both cables same problem. The roku by itself without the extractor is fine. Connected to SHARP digital projector.The previous hdmi audio extractor I used (forgot which) would sometimes just show static on the whole screen for a second.My recommendations: either ditch the roku ultra for a box that actually has analog outputs (If i had known about these problems I probably would have gotten some android based box even though i really like the roku interface), or get an actual hdmi receiver.

My portable monitor doesn’t have audio jack adapter so this thing solved it
