delay on most Home Theater Systems with a disc player to
match the sound with the video.

Audio out settings
Audio out delay
With a Home Theater System (HTS) connected to the TV, the
picture on the TV and the sound from the HTS should be
synchronized.
Automatic audio to video sync
With recent Home Theater Systems, the audio to video sync is
done automatically and is always correct.
Audio sync delay
For some Home Theater Systems you may need to adjust the
audio sync delay to synchronize the audio to the video. On the
HTS, increase the delay value until there is a match between
picture and sound. A delay value of 180ms may be required.
Read the user manual of the HTS. With a delay value set up on
the HTS, you need to switch off Audio Out delay on the TV.
To switch off Audio Out Delay...
1 - Press the Settings key, select Sound and press  (right) to
enter the menu.
2 - Select Advanced > Audio out delay and press OK.
3 - Select Off.
4 - Press  (left) repeatedly if necessary, to close the menu.
Audio out offset
If you cannot set a delay on the Home Theater System, you can
set the TV to sync the sound. You can set an offset that
compensates for the time necessary for the Home Theater
System to process the sound of the TV picture. You can set the
value in steps of 5ms. Maximum setting is -60ms.
The Audio out delay setting should be switched on.
To synchronize the sound on the TV...
1 - Press the Settings key, select Sound and press  (right) to
enter the menu.
2 - Select Advanced > Audio out offset and press OK.
3 - Use the slider bar to set the sound offset and press OK.
4 - Press  (left) repeatedly if necessary, to close the menu.
Audio out format
If you have a Home Theater System (HTS)
with multichannel sound processing capabilities such as Dolby
Digital or similar, set the Audio Out Format to Multichannel.
With Multichannel, the TV can send the compressed
multichannel sound signal from a TV channel or connected
player to the Home Theater System. If you have a Home
Theater System without multichannel sound processing, select
Stereo.
To set Audio out format...
1 - Press the Settings key, select Sound and press  (right) to
enter the menu.
2 - Select Advanced > Audio out format and press OK.
3 - Select Multichannel, Stereo or Multichannel (bypass),
then press OK.
4 - Press  (left) repeatedly if necessary, to close the menu.
Audio out leveling
Use the Audio Out Leveling setting to level the volume
(loudness) of the TV and the Home Theater System when you
switch over from one to another. Volume differences can be
caused by differences in sound processing.
To level the difference in volume...
1 - Press the Settings key, select Sound and press  (right) to
enter the menu.
2 - Select Advanced > Audio out leveling and press OK.
3 - Select More, Medium, or Less, then press OK.
4 - If the volume difference is large, select More. If the volume
difference is small, select Less.
5 - Press  (left) repeatedly if necessary, to close the menu.
Audio Out Leveling affects both the Audio Out - Optical and
HDMI ARC sound signals.
Problems with HTS sound
Sound with loud noise
If you watch a video from a plugged-in USB flash drive or
connected computer, the sound from your Home Theater
System might be distorted. You can fix this by setting the Audio
out format of the TV to Stereo.
