hi for all,
just another little question, I can't use the solution proposed by Mr KatieandDad (put a resistor in series with the volume control ) because for volume control I intend to use the Toshiba, electronic volume "TC9153", so any help more!!
thanks

yes you can use resistor network.
That ic has an output, and the amp has an input.
What you do is connect the resistorts between them.

why you need that IC for volume controll?
