Review on 🔊 U9 ViewHD VHD-UHAE Ultra HD 4K HDMI Audio Extractor - 4K@60Hz, HDR, Dolby Vision, 3.5mm Headphone Stereo Output, Toslink Optical Audio DD+ Output, HDCP 2.2, HDMI 2.0, 18Gpbs by Alton Walton

Update: Was so happy with the original VHD-UHAE (5.1, 4k audio and Dolby Vision) that I decided to try VHD-UHAE2 to get DTS, 7.1 etc. He said he still had Dolby Vision. Used the same HDMI cables as for VHD-UHAE and Dolby Vision did NOT work. Audio was output in DTS format. Bought new HDMI cables because that was their solution to the problem. Still does not work. Returned to UHAE2 and just stayed with the original 5.1. Wow, never thought this would actually work. I bought a new 4K TV, but my audio receiver is over eight years old. 4K video cannot be played. Instead, I figured I'd use my TV's optical output to connect to the receiver. Huge audio latency issues. The same with the fire stick. I guess I'll try that before spending $400 on a new receiver. As it turned out, the investment was fully justified. $40 vs. $400, huge savings. I haven't had much success getting DTS to work, but Dolby Digital is perfect.
