Changing the audio mode
The TV has two audio modes, accessed by navigating in the
Home
screen menu to
Settings >Audio > Audio mode
:
•
Stereo
– Use this setting for internal speakers, headphones, and external stereo amplifiers connected through
HDMI ARC, SPDIF optical, or headphone jack.
•
Auto
– Use this setting to automatically detect the best audio setting based on the audio stream in the content
you are watching. If you have connected the TV to an external Dolby Audio compatible amplifier, receiver, or
sound bar through HDMI ARC or SPDIF optical, the TV automatically selects the appropriate surround sound
capabilities of the device based on the characteristics of the current program.
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 “
” on page
•
SPDIF
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.
Controlling other devices through CEC
Consumer Electronics Control (CEC) enables your TV and other CEC-compatible home entertainment components to
control one another in various ways. First, the CEC-compatible devices must “discover” one another and report their ca-
pabilities. After this, one device can control another according to the features you enable. For example, playing a disc on
a Blu-ray player could switch the TV to the Blu-ray player’s input. Or, powering off the TV could also power off the Blu-ray
player and the home theater receiver.
