The television sound is louder during a commercial or when changing between television channels.

Most TV commercials are created to be loud simply so you can hear the advertisement and get your attention. The Federal Communications Commission (FCC) does not regulate the volume of commercials, nor does it regulate the volume of TV programs. But, the FCC does require broadcasters to limit the power that is used to transmit the signal. So, technically, a commercial cannot be any louder than the loudest portion of the TV program you are watching. That said, however, if you are watching a program with soft dialog, when the program cuts to a commercial you will most likely hear a boost or fluctuation in the volume.

Some Sony® TV models have built-in technology or settings that can help compensate for these sound differentials between a program and a commercial. Here are some suggestions:

IMPORTANT: If model-specific information is required to complete any of the steps in this solution, refer to the operating instructions supplied with the TV. Manuals are posted on your model support page.

1. If the TV has Steady Sound® volume control, set it to On.

   IMPORTANT: On certain model TVs, the Steady Sound feature may only works when the RF input is being used; for some models it work with composite, component or HDMI® inputs.

2. If the TV has the Advanced Auto Volume  feature, set it to On.
3. If the TV has sound or audio effect options (Simulated, SRS, WOW, or TruSurround), try changing the effect option to Off.
4. If the previous options are not available on your TV, use the MUTE or MUTING button on the TV remote control.
