Changing the audio mode
Your 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 the
HDMI1 (ARC), OPTICAL DIGITAL AUDIO OUT, 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 your TV to an external Dolby Digital or Dolby Digital Plus compatible
amplifier, receiver, or sound bar through HDMI1 (ARC) or OPTICAL DIGITAL AUDIO OUT, your 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 your TV to an external amplifier, receiver, or sound bar by using either of these two connections:
• HDMI ARC—The HDMI Audio Return Channel enables your TV to output digital audio on one of its HDMI
connectors. The connected amplifier can also function simultaneously as an input source to your TV, if needed.
To use the ARC capability, you must connect an HDMI cable from your amplifier's HDMI ARC connector to the
HDMI1 (ARC) connector on your TV. You also must:
• Be sure your HDMI cable is certified by HDMI.
•Enable HDMI ARC under Settings > System >Control other devices (CEC), as explained in Enabling HDMI ARC on
page 69.
• SPDIF—Your TV has an OPTICAL DIGITAL AUDIO OUT connector that outputs a digital audio signal. To use the
optical output, connect a digital optical audio cable from the amplifier to the OPTICAL DIGITAL AUDIO OUT
connector on your TV.
After making the required HDMI ARC or digital optical audio connection, go to Settings > Audio > S/PDIF and ARC
option and select the audio format to use.
Controlling other devices through CEC
Consumer Electronics Control (CEC) enables your TV and other CEC-compatible home entertainment components to
control one other in various ways. First, the CEC-compatible devices must “discover” one another and report their
capabilities. 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 your TV to the Blu-ray player's input. Or, powering off your TV could also power off the
Blu-ray player and the home theater receiver.
Discovering connected CEC devices
To discover CEC devices:
1 Make sure that your CEC-compatible components are connected to your TV with a suitable high-speed HDMI cable
that supports HDMI ARC and CEC control.
2 Turn on each component and make sure all components have CEC enabled.
3 On your TV’s Home screen menu, navigate to Settings > System > Control other devices (CEC) and then select
Search for CEC devices. Press OK to repeat the discovery process, if necessary.
When finished, your TV displays a list of CEC devices that are connected to each HDMI input, as well as any devices that
had previously been connected. Your TV remembers the names of multiple CEC devices even when they are no longer
connected. If the list is longer than the allowed space, press to see a complete list in a scrollable window.
Note
Dolby Digital Plus format is not available through the OPTICAL DIGITAL AUDIO OUT
output. This format is only available through the HDMI1 (ARC) connection.
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.
Tip
Some manufacturers have their own branded names for CEC functionality, so you
might need to read the product documentation to correctly identify the CEC features
of the device.
