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.
