Default AD1955, WM8741... CONTROL VOLUME

Hi guys, I was wondering if there is any easy way to control the volume function que the chips (AD1955, wm8741. Dac and others) have internally.

I saw only one circuit on the internet, that can handle it, is through the PIC, but I have no knowledge / euipamento metedo for this, besides, I would have to make such a large circuit like own dac just to control the volume.

I can not stand channel error caused by potentiometers, and I have no money to buy a quality attenuator

any suggestion is welcome, thank you gentlemen.

Check into Arduino.
You can buy modules ready made.
Software is open source and you can
often find software to control whatever
chip you have. There is also a great support
community to help you along.
Tinkering is what happens when you try something you donít quite know
how to do, guided by whim, imagination, and curiosity.

See the hifiduino website:

Alternatively, the following project may be of interest if your only concern in using an affordable log taper stereo potentiometer is their typically poor inter-channel tracking.
