Review on 🔌 4K HDR Dolby Vision Atmos Down Scaler HDMI Splitter 1x2 - HDMI Scaler 4K 1080P Sync, 4K 60Hz 4:4:4 HDMI Splitter 1 in 2 Out HDCP2.2, EDID 4K5.1/4K7.1/Copy, for Xbox PS5 1080p120Hz Roku SP12H2 by Lamont Wilson

So I found out the hard way that this thing is missing a very important feature and I don't understand why. The hardware is blocking this, it's in a random document in a 60MB download, but it's not mentioned anywhere here. I would never have bought it if I had known. The whole reason I bought this device. Explains why I only get a stereo signal and it's totally static. If I had known that beforehand, I wouldn't have bothered! It should just pass the audio through untouched, but that only seems to happen if you've reversed the setting or kept 4K across the board.
