Some days ago, we introduced some HDMI audio extractor converters with different HDMI version (HDMI 1.3, 1.4 and 2.0). In addition to the HDMI version, the function of splitting the audio is the same.
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.
