About my tv type: 32PFL5606H/12 s/n: FZ1A1202039501
I read in the Technical Charateristics about the sound:
Accentuation du son: Auto Volume Leveller, Clear Sound, Incredible Surround, Réglage graves/aigus

I want to know if this option "Auto Volume Leveller" is always on ?
If not, how can i set it ?
