it's not likely to be the speaker causing it, it has to be receiving some kind of power when it shouldn't be to be making a sound, its more likely to be something on the sound file at fault

I’ve the same problem on a class 33.  Never found a solution.

I read on another forum that the 'humming' sounds on some ESU Loksound decoders may be caused by the BEMF circuitry.

 

Supposedly, this has been fixed by ESU with the latest Loksound V5.0.

Thanks, when I get the opportunity I’ll try a v5 in my 33 and see if it solves the problem.
