Setting up a digital audio connection
You can connect the TV to an external amplifier, receiver, or sound bar by using either
of these two connections:
•
HDMI ARC
– The HDMI
®
Audio Return Channel enables the TV to output
digital audio on one of its HDMI
®
connectors. The connected amplifier
can also function simultaneously as an input source to the TV, if
needed. To use the ARC capability, you must connect an HDMI
®
cable from
your amplifier’s HDMI
®
ARC connector to the
HDMI ARC
connector on the TV.
You also must:
o
Be sure your HDMI
®
cable is certified by HDMI
®
.
o
Enable
HDMI ARC
under
Settings > System > Control other devices (CEC)
, as
explained in
Enable HDMI
®
ARC
.
•
SPDIF optical
– The TV has an SPDIF optical connector that outputs a
digital audio signal. To use the optical output, connect a TOSLINK
optical cable from the amplifier to the Optical or SPDIF connector on
the TV.
Note
:
Dolby Audio™ supporting Dolby Digital Plus™ format is not available
through the SPDIF optical output. This format is only available through the
HDMI
®
ARC connection.
After making the required HDMI
®
ARC or SPDIF optical connection, go to
Settings >
Audio > S/PDIF and ARC
option and select the audio format to use.
Note
:
In most cases,
Auto detect
is the best option. Other settings can result in no sound
when the content you are viewing does not contain the audio stream type you
selected.
