Oh I read the whole thread, maybe not in too much detail, too busy building the board

Yeah, FarmTech has your name displayed on the lCD on board start up.

I just need to get the board installed in a box with pre-amp.

Cheers

Hmm , I dont have any problems with a normal FM radio
I even have a I2C radio board on pcb (AR1010) (TEA5767 radio chip)
even weak radio stations comes in ok no MCU noice
but I have a 0.002V 50 hz hum but its ok , I can only hear it if I pump up volumt to full and no input connectet

Can you take a picture of you build so we can see how it is connectet in the case ?

My take on this volume controller, completed 80% but its already working great

It's attached after a NOS DAC + JBoz kinda line amp.
I plan to add in the future a B1 buffer after the controller to have lower the output impendace.

Of course there is a lot of work on the case yet. I want to paint it black and to add nice wood front and back panels. Lets see what wood my carpenter friend recommends.

Cheers!

p.s. @FarmTech: I found some bugs with the volume controller software, I will create an error list and send it to you, hope you can fix them
