I bought this switcher to switch between a Nintendo Switch, PS4 and an old DVD player. The automatic detection works, it always switches to the active device. The only thing I had to say about the PS4 is that although the TV can do HDR and also tells the PS4 so, this does not work via the throttled Switch connection (HDR Off for PS4). However, I have noticed that the Apple TV4K (first generation) can no longer switch on the TV - even though it has its own HDMI port directly on the LG OLED CX (2020 model). Even more troublesome is that the Sonos Arc connected to the TV's eARC no longer works properly. It emits sound, but the Sonos app thinks the connection to the TV is faulty. Also, the volume can no longer be adjusted - except via the touch buttons directly on the Sonos. When I disconnect the switcher physically, everything works again. Switching off all the devices connected to the switcher does not solve the problem. Has anyone had any experience in this regard?
