I have a 2 yo. soundbar that started making annoying popping and buzzing so und (like AC hum but with more harmonics). I replaced some electrolytic cap s that looked a little bulged. The buzzing sound went away but the popping still exits. Some times it pops as frequently as every few seconds. It does not matter which input is selected but loudness does change with volume co ntrol. Any idea where I should look into, or what could possibly be the sou rce of the pops? The amplifier is class D, which may or may not be relevant to the problem.
