described in “Enabling system audio control” on page 57. The internal speakers are also turned o when you

Changing the audio mode
The TV has two audio modes, accessed by navigang in the screen menu to :
• – Use this seng for internal speakers, headphones, and external stereo ampliers connected through
HDMI ARC, SPDIF opcal, or headphone jack.
• – Use this seng to automacally detect the best audio seng based on the audio stream in the content
you are watching. If you have connected the TV to an external Dolby Audio compable amplier, receiver, or
sound bar through HDMI ARC or SPDIF opcal, the TV automacally selects the appropriate surround sound
capabilies of the device based on the characteriscs of the current program.
Setting up a digital audio connection
You can connect the TV to an external amplier, receiver, or sound bar by using either of these two connecons:
• – The HDMI Audio Return Channel enables the TV to output digital audio on one of its
HDMI connectors. The connected amplier can also funcon simultaneously as an input source to the TV, if
needed. To use the ARC capability, you must connect an HDMI cable from your amplier’s HDMI ARC connector
to the HDMI ARC connector on the TV. You also must:
o Be sure your HDMI cable is cered by HDMI.
o Enable under , as explained in “Enabling
HDMI ARC” on page 57.

– The TV has an SPDIF opcal connector that outputs a digital audio signal. To use the
opcal output, connect a TOSLINK opcal cable from the amplier to the Opcal or SPDIF connector on the TV.
• : Dolby Audio supporng Dolby Digital Plus format is not available through the SPDIF opcal output. This
format is only available through the HDMI ARC connecon.
Aer making the required HDMI ARC or SPDIF opcal connecon, go to opon and
select the audio format to use.
In most cases, is the best opon. Other sengs 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-compable home entertainment components to
control one another in various ways. First, the CEC-compable devices must “discover” one another and report their ca-
pabilies. Aer 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 o the TV could also power o the Blu-ray
player and the home theater receiver.
