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.
