Speakers balance changes

I have computer speakers that are going through some balancing acts whereby when playing video online the right speaker will stop playing. I get off video or news, etc. or offline, and testing through the Realtek audio manager/controller the left speaker goes out.
Testing moving balance to the full left-nothing. Put balance in middle it plays right speaker only and fully to the right plays right. And plays the left side as well because they have one speaker test that when hitting it will do a jingle from the left and then to the right and now plays both left and right in the right 'only.'

The speakers are pro media 2.1 computer (bluetooth) speakers. However, since I opted off purchasing the wireless speakers and wanted the regular wire/cable to plug to the outlet, i have always used them in that way. I finally determined why they play my neighbors music when they play it on patio, it plays theirs "only" and then if i switch and turn on my own speakers to the bluetooth is how win-over that output. But i don't like the bluetooth part of playing them because i lose the function of the audio control/Realtek audio manager where you can enhance sounds with selecting Rock or Pop, etc... So, i just turn off or not connect the bluetooth on most and much of the time basis. Other different anominally (spellchek-sorry) The speakers stay on always, per the manufacturer Klipsch for purposes of not surging electricity, i guess or for the most part out of reading terms, etc. and that language, but yes, there's no power off or on and i've unplugged many times when taken over by the signal Bluetoothing, as i call it, when neighbors play their music outside and it likes their wares better because i totally lose my sounds to theirs when.. :)
Any ideas or suggestions on this one?

My 2 cents. Get regular PC speakers for the PC and dump the Bluetooth's.
I would suspect all your problems are the Bluetooth speaker system.

It could be bad capacitors as I stated in another thread.

Is there a permanent fix for Realtek left/right balance bug Win10?

It could also be dust in the potentiometer (the volume knob) --- squirt some rubbing alcohol (not wd40) and clean it.

Thanks for showing this video link and i can see that this is one of the things that i must do because it is so sensitive right now and i hoped it wasn't going to start that when you barely touch knob hissing frizzing stuff. I updated the Realtek drivers (this is on a Lenovo PC and they have a 2020 upgrade but it shows 2019 on the driver properties.
There is the other reply too, that Aman you're probably good advise to ditch the bluetooth, it took me all this time and other threads and didn't find out till the aha-moment to learn that since i had Bluetooth it would play the other people's music that i share patio between my door and theirs and they bring out hellacious (well not that bad) but their device or receiver what ever my speakers would play theirs automatically w/out fail every time for 2 yrs.
So, by this point, i was destined to find a reason why...(why the rush-right:)?) but it turns out if i connect my Bluetooth to my speakers, then it's normal or there's no hijack or signal doesn't automatically take over, etc... However, then I lose touch or connection to the Realtek Audio manager/controller. So, i am not using Bluetooth and it's worked out so far since i detached B Tooth and they played their music couple times (now) already and my speakers didn't even pick up their signal and i've (like I said) not had it tuned in to Bluetooth. So...
THanks a lot for you guys' most helpful info. & video.
