I use Direct TV satellite receiver.

For the monitor connected via HDMI camble:
Element Electreonics 40 inch LCD, ELGFT401

After following all the setup, several things make NO sense.

What is 'automatic volume control'?

The manual says ON/OFF to turn the automatic volume control on or off,
which is not a lot of help.

How do I adjust the range of control down to a LISTENING level.
In the manual only describes if it's not loud enough for you?!
Note: the volume control settings are
0 is NO SOUND
1 is daytime comfortable listening, maybe up to 2 or 3 to 'feel' the
sound.
Everything on up to 99 is louder than a party of Americans in a
restaurant.

The problem is that at night, 1 is TOO loud, hurts ears, It is an
upsetting level.
Again, 0 is OFF so there is nothing in between.

Any ideas on ways to adjust the range ...without cutting into the
unit?

Anybody have a ??update.pkg file I can download through the monitor's
USB port to change what they gave me? Seriously, above 4 or 5 the
sound HURTS your ears, like a Rock Concert! So need an easy way to do
this.

I fear 'blocking' the speakers with sound absorbing material will only
filter the sound rendering the speech unintelligible.
