If you need more HDMI 2.0 ports and extract audio from source devices to your audio receiver simultaneously, the best solution is HDMI 2.0 switch with audio output, which can simply be considered as the combination of HDMI 2.0 audio extractor and HDMI 2.0 switcher.
If your TV has only one HDMI port, but you want to use several HDMI devices (such as PS3, Apple TV, Roku, DVD Player,etc.) on your TV. The best way is to get an HDMI device to expand your HDMI ports on TV. Do not try to unplug HDMI cable to change input device, which will damage your HDMI port.
