Selecting virtual surround sound
You can enjoy emulated surround sound from the TV
speakers. To do so, in the Audio menu Virtual Surround
option, 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 at the speakers, or at the
external sound system 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
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.
The following table shows the audio output
dependencies and the resulting output.
