YES ! . . .. and easily.

Your audio amplifier is the problem.

Does that happen because the voltage given from the amplifier is too high?

Not necessarily, but when an amplifier begins to hum that suggests ground loop or the power supply is injecting pulsating power into the speaker through the amplifier. In any case your audio amplifier is probably the problem.

If I had another speaker or another amplifier it would be easy enough to determine which item speaker or amplifier is the problem or both by switching the items around and seeing which always exhibits the hum.

A normal system puts more power (heat) into a speaker as the volume increases. But a rippling unfiltered DC would be low volume with a high current heating the speaker.
