OK, I will put if differently: have you ever noticed the cores of small signal transformers being remanently magnetised causing audible problems ? I know I did but I take it you see more audio transformers than I do in daily life.

To be honest, no.
I prefer largish cores though wrt the application so that might help prevent any problems.
"Self healing" when applying audio signal to magnetized cores might work sufficiently in a number of cases also.

Is the remanence having an effect similar to an additional flux and making the core easier to saturate?
If so, testing for the level of maximum undistorted signal and whether this level changes after a milliamp is passed through the coil would be a fair experiment.
