BAD: sounds bad (white noise as soon as the sub is plugged in, "cracking sound", hissing)

The sound system was working well at first, then after 4 months, the speakers started to have a lot of loud white noise (even when it was off)

So I’m returning and re ordering to see if I got faulty speakers will update review if that was the issue.***UPDATE***New system showed up today 2/14 and I set it all up and the hum/ring noise is gone on the left and right speakers and the system sounds great for the price.

Item worked nicely through AmazonBasics digital optical audio Toslink cable about 1 week ,then suddenly (when my toddler was watching cartoons )turned to extremely loud noise and It very frightened him

Also it makes a lot of annoying beeping noises every time Bluetooth is connected

it began to make a loud humming noise when ever the base was on, and only would go away when bass was turned all the way down.

When I have it turned off it continues to make a humming noise and pulls tons of power

I contacted LuguLake support and with troubleshooting instructions was not able to make the hum/ringing noise go away

It had major static/white noise playing on the Bluetooth, it was very loud while you played anything

After just a few weeks it all of a sudden makes weird noises even when off

Gives off a horrible buzzing noise.

After a few weeks it started making hiss noise

My problems was when left idle with no music on even when off I could hear a hissing noise

But when it is off, it makes weird static noises.

They sound pretty good other than that, but I just can't listen to them with a constant humming noise

Only worked through one output (Roku) while trying an optical cable, every other (TV and USB) just produced static noise

We can actually hear even the soft noises previously unheard on our TV.

Loud Buzzing noise and wont stop
