The first thing you need to do when trying to use hdmi cables high speed for you TV is to check the HDMI version supported by the TV. Check if your television supports HDMI 1.4 ARC (Audio Return Channel). This allows the TV to send audio back to the receiver that sends TV sound to the speaker or voice for the home theater. Most TVs made after 2009 supports HDMI 1.4 and above.
If your TV does not support HDMI 1.4, you must use a separate audio cable to connect the TV to the receiver. Best quality cables that can be used are an optical digital audio cable. Connect a digital optical cable from the TV output to the receiver input.
If you watch TV through the cable box and the cable box is connected to a receiver, you do not need to use ARC because the sound is sent from the cable box to the receiver. ARC is only required if you are watching broadcasts air programming (over-the-air) on TV and wanted to voice out through the surround sound system.
