Hi,
I'm working with a Maxim 5456 10K digital pot.
Everything is functional however I'm getting major
distortion in the audio.
I'm wiring it in place of a standard pot, H end (input),
Wiper(output), L end to GND. it's between the cd player's
output and a preamp.
any suggestions as to what I may be doing wrong?
thanks

It's because it is a single-supply device and the signal has to be referenced to a point in the middle of the supply voltage so the device can swing above and below it. This is similar to using an op-amp with a single supply voltage: you need a reference voltage somewhere in the middle. You're probably hearing what it sounds like with only the positive swings. clipping everything below 0.
