For some Home Theatre Systems you might need to
adjust the audio sync delay to synchronise 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.

Audio out offset
If you cannot set a delay on the Home Theatre
System, you can set the TV to sync the sound. You

necessary for the Home Theatre System to process
the sound of the TV picture. You can set the value in
steps of 5ms. Maximum setting is -60ms.
