HDMI enabled Digital Television Displays have always been able to receive
multi-channel audio through an HDMI connection, and this is still a typical
situation, with the TV positioned “downstream” from content sources and any
connected audio equipment. However, if a user had a TV with a built-in tuner or
DVD player, and wanted to send content “upstream” from the TV back to the
audio system once it had been decoded, a separate connection had to be
installed from the display device back to the audio amplifier, typically an S/PDIF
cable.
An Audio Return Channel-enabled TV can either send or receive audio via HDMI,
upstream or downstream, depending on system set-up and user preferences
which means that limitations of the S/PDIF approach are minimized.
When Audio Return is set to “Off”, the standard rules of HDMI audio handling
apply as summarized in the following chart: Examination of the chart will show
that there are situations where you cannot always recover the decoded audio
from the display device using the S/PDIF approach due to bandwidth limitations
or due to the display device not being able to decode all audio formats.

Enabling Audio Return (turning it on via the OSD Menu), allows full support of
audio that has been de-embedded at the display device using the same HDMI
cable that sent the signal to the display device for the return audio path to the
audio distribution system. This is superior to using a separate S/PDIF coaxial
cable from the display device back to the audio distribution system, particularly
since there may be situations where the display device may not de-embed a
particular signal type.
