My TV is viewed via Humax box the sound control is fine can set to a comfortable level, that is, until the adverts come on, and sound then rises to a lesser comfortable level. Why does it do this automatically?
For those who likely to
comment on searching net, I HAVE, and nothing showed about this problem.
Many thanks

Its not peculiar to the Hummy box. Its something mindless advertisers do.

Its not actually that the ads are louder but the sound levels are compressed, making the quiet bits almost as loud as the loud bits - its something public address systems have been doing for ages in order to uniformly "punch" varying voice levels above the background.

Plenty about it on the Internet:
