Could the volume pot be the cause, and if so, how to test?

Yes

VOM

You will probably have to remove the connections. Turn the control end to end, Test resistance from both ends to center. The change in resistance should be smooth and continuous. The rate of change depends on thr taper of the pot - Audio (log) or linear taper.
