Very simple volume control with IR remote

I want to build a very simple digitally controlled analogue volume control that can be controlled with the GPIO output from a Raspberry Pi. This would also allow integration of an IR remote control going through the Raspberry PI.

I only need volume control, no trebble or bass. No input control: only one input. I don't need and LCD. LED indicators would be nice but not necessary.

High end quality a plus but medium quality also OK. Preferably no POT.

And yes, it should be economical...

I have been searching the forums and the web but can't really find anything appropriate, but I may be looking in the wrong places. I don't have much experience building these kind of things (yet).

Thanks for your suggestions!
