If you connect a BRAVIA™ Sync-compatible soundbar to your TV, and the BRAVIA Sync or Control for HDMI setting is on, the TV shows a different volume display. It's normal for the TV volume display to change when you switch the Speaker Output from the TV Speakers to the Audio System.
For example, if you connect a TV with a maximum volume output of 100 dB to a soundbar with a maximum volume output of 50 dB, the TV volume display shows proportional value to the output of the soundbar.
TV Volume Display: 40dB
Soundbar Output: 20dB
