Hey guys new to acura tl world and I've been dealing with this annoying whine/hummm. I've searched and still in same spot.

99 tl 114k on it I have replaced power steering o-ring replaced idler pulley and serpentine belt. The noise honestly has gotten lower. So I pulled off the serpentine belt with power steering belt still connected and I hear nothing. So I guess I can rule out power steering.

Also I have noticed that when I use any power the sound gets louder(ie. turning headlights on, holding brake, turning on signals, and when fan keeps on. Immediately after everything is shut off noise quiets down. There is no amp or sub in car but wires are ran to trunk. My question now is can this be the alternator pulley or alternator itself making noise. Where should I start looking.
Idk if alt. has ever been replaced
