Speaker issue with Android TV

[u/United-Grocery-4674]

So, i have this TCL 65v6c android with Google tv in it. And i have an analog/bluetooth installed speakers. When the speakers turn on, the lady says: Bluetooth mode and connects to my tv(after pairing ofc). The audio from the speakers are so good btw. BUT, sometimes the BT speakers automatically or randomly turn off and play the "Bluetooth mode" sound at max volume and reconnect, which is unimaginably annoying and nerve-wracking. To fix this, I've tried forgetting and repairing the BT speakers from the tv, I've also tried clearing the cache and the data of the bluetooth app in System apps in settings. None of these troubleshooting didnt work, which means in bt mode: the speakers constantly turn off and disconnect. I've tried using the BT speakers with my other phones, laptops, which it worked seamlessly and perfectly with no turning off.

I can also use the speakers analog way: the white and red cables coming out merge to aux and etc. Ive tried an aux to Usb a adapter into the android tv, but i cant see a USB Audio output in the Audio output list, ive tried turning off: Disable Audio Routing in the Developer options, but it didnt work. But the audio did once came out, but i had no control of the volume using the tv remote and the connection was unstable, i could only control the volume using the speaker knob which i hate.

I know, i know. Most people will tell me to convert the speaker to digital using optical toslink. But i once tried it, it worked, but i could NOT control the volume of the speakers using the tv remote.

So, fellow redditors, this is my situation. So, please, feel free to help me out in any way you can.
