Review on Powerful 4K HDMI Splitter by J-Tech Digital | Ultra HD 3840x2160 Resolution | 3D Support | 4 Ports HDMI Splitter 1X4 by Adam Taylor

You need a device to negotiate and manage the connection. Don't connect to it directly. Connecting directly will result in a 48k audio stream instead of a 192k audio stream. This is required to customize this device. I'm currently using an HDMI pass-through DAC to power this unit, but unfortunately it's only HDMI 1.3 and only accepts stereo. -. Some receivers only show you what's at the other end of their channel, others use the connection and still others downmix your stream to eg 16bit/44.1k. Be careful when looking for a device that can be connected to this splitter. The HDMI switch doesn't work, FYI. It's just a passage so he doesn't agree with anything. You negotiate with the device on the other end. This device negotiates when nothing is set since it has multiple endpoints and requires some nasty stuff. Anyway, just a warning ^_-.
