I have now had the same issue, and it is occurring more frequently, and lasts a lot longer. I have not had my PM2.1 BT work for two days now. Occasionally, I can get the sub to emit some volume, but it is unintelligible due to no mids or high ranges. Even connecting the analog cable to my phone does not play sound, so it is something in the Sub's main board that is going out. It is super annoying!

I am also in the same mind as others that question the 1 watt standby draw, because my subwoofer is always warm! The carpet under it is also warm! I think I will add a switch somehow. I did find the schematics on another posting, so it shouldn't be too difficult I wish I had a heat gun, but I suspect I would read about 110F on the back of the sub, even without any sound going to it. I do wonder if having the sub connected via a 1/8" analog stereo cord causes a load and my system is actually not ever going into Standby?

I hope they return with results too!

So I have managed to find a "workaround" for my buzzing. I can position the wire from the Right Speaker Control Module that connects to the subwoofer in a way that the buzzing stops. If I accidently move something on my desk, and knock the cable out of position, then the buzzing is returned, but I can quickly find the cable's position to stop it from buzzing/humming. When the humming is not present, these speakers are honestly a dream and deliver a punch of bass and sound!

Sadly I have joined the group of folks that have the hum, and basically I can't use my subwoofer. I work from home, so I have music on all the time, but lower volume to focus and that is how I heard the hum. These speakers were unused for about 20 months, and just got pulled out of an environmentally controlled (Air conditioned) storage unit, so I know they are in like new condition, so I am at a loss of where the hum is coming from. I have it plugged into a CyberPower UPS, and the UPS shows the home wiring has a proper ground, and I get the hum even when the 1/8" analog stereo jack is not plugged into my docking station. Has anyone found a fix? I lost all my purchase paperwork so I may be SOL I fear.
