Setting up a digital audio connection
To take advantage of your TV’s advanced audio capabilities, connect it to an external
amplifier, receiver, or sound bar by using either of these two digital audio
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 SPDIF optical connector 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.
