Choosing the digital audio output mode
You must be watching a digital TV channel to access
the Digital Audio option in the Audio menu. This option
sets the format for the signal provided on the Digital
(Optical) Audio Output connector on the rear of the TV:
Dolby Digital or PCM. Select PCM if your external
digital audio system does not support surround sound.
See "Understanding audio output" on page 54.
Selecting virtual surround sound
You can enjoy emulated surround sound from the TV
speakers. To do so, for the Virtual Surround option in
the Audio menu, select the mode that you want to
hear: Theater or Music Hall.
Understanding audio output
The input source signal and the Audio menu settings
for Digital Audio and Speaker determine the type of
audio output that you hear from the TV speakers, or
from the external sound system that is connected to
the TV.
For example, if you connect an external sound system
by using the Digital (Optical) connector, you hear
digital sound from the connected external audio system
when you watch a digital TV program. The format of
the digital signal that the TV provides depends on the
Digital Audio setting (Dolby Digital or PCM).
This TV does not support Dolby Digital audio input over
HDMI. When connecting a set-top box, DVD player, or
other device by means of HDMI, set the device audio
output to PCM format.
