Pros: Works at 4K and 60hz Optical and Audio Out both output at the same time. Cons: Surround Sound does not work on a LOT of devices. I bought this to get sound off an HDMI cable. My setup doesn't work with an audio output from the TV which is why a box like this would exist. It is to get sound off the HDMI cable before it enters the TV. The only device that worked with surround sound off of the optical cable that I tested was a PS4. When you go into the audio settings on the PS4 you can change the sound type to Dolby Digital and the optical output on the converter will actually output surround sound. On every other device I tested it only outputted stereo so only my front speakers were working. I have tested this on: 1) A high-end gaming PC with a 1080 TI graphics card. The 1080 TI can output audio off of the HDMI output. However the problem is that since this converter is an HDMI pass-through the sound output the computer sees is just the TV. It doesn't see the J-Tech device as an output which is probably the issue that every other device I tested also experienced. My computer saw my HDMI output to my LG TV as an output. Since the computer only sees the LG TV it knows the TV only has stereo speakers and so it forces my computer to only output with a stereo signal, so my rear speakers don't work. 2) Playstation 4 - This is the only device that worked because the PS4 has an audio setting where you can force the output audio type to Dolby Digital and it allows the optical output from the converter to send a true 5.1 surround sound signal through the J-Tech device. 2) Nintendo Switch - The audio settings on the Nintendo Switch lets you select Stereo or Surround Sound, but not specifically Dolby Digital or other types. So I could only get a stereo signal off of the converter. 3) Xbox One - Same issue as PC and Nintendo Switch. Can't output a 5.1 signal because it only sees the TV as a stereo setup. 4) Sony BluRay Player - Only outputs stereo Again the main problem is that most devices don't see the J-Tech box as an audio output. It passes the signal through to the TV so the TV is seen as only a stereo output. Even though I have a 5.1 Logitech Surround Sound system plugged into the optical output on the J-Tech converter most devices only see the TV as a stereo device so it only sends a stereo signal. I even switched the J-Tech device to the 5-Channel position and it still does the same thing. Unless you have a PS4 or only need a stereo sound signal this device will not work for you.
