Setting up a digital audio connection
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
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 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.
