HDMI technology transmits crystal-clear digital 

multi-channel surround audio through a single 

HDMI cable. Audio Return Channel-enabled 

(ARC) TVs allow audio to be sent over an already 

connected HDMI cable, eliminating the need for 

a separate audio cable. See 

Optical/SPDIF cables transmit audio signals as 

pulses of light through a cable made of plastic 

fibers.  Audio  signals  are  digitally  transmitted 

between devices.

RCA cables (or Composite cables) are the traditional 

way of connecting your devices to your audio 

device. Audio signals are sent over the red and 

white connectors.
