No sound when use HDMI connection with Orbit Pro

1. Please notice that the HDMI ARC only works with TV HDMI ARC port.

2. Please use an HDMI cable v1.4 or higher.

3. Make sure switch the Orbit pro to HDMI mode and set the  audio output of your TV to "HDMI ARC" out.

*4. Please make sure the audio source (like TV) is turned on BEFORE the transmitter is turned on to initiate the effective HDMI ARC handshake. 

5. If your transmitter is always on by premaritally connected to a power source, you can switch the mode to AUX and then back to HDMI to activate the effective handshake.
