I seem to have a problem with the volum control on my headphone station. The lower 2/3 of the control does not work all the time. I can turn the knob but nothing happens until i reach a certain point and then the sound shoots up in volume. I also am unable to change my soundtracks by dialling down. It used to work fine but stopped this week.
Any idea how to fix this since my Tommy is set to make an appearence at the Dutch Pinball Open 2018 in november and i want it working by then.
