How to fix hijacked devices that I use?

It is been more than 3 years since I have occasionally received an audio modification in my phone and pc while listening to music on any software or watching videos e.g on youtube or Facebook. What I mean by modifications is believe me or not that audio is being modified and abusive words were added to the audio or even some words in sentence replaced into abusive words of current voice, sometimes that bad that I can’t learn anymore. Some days more often and some days less.

At first, I couldn’t believe that’s happening. It is very unpleasant as you can imagine I love to learn, watch tutorials and listen to normal audio as it should sound. I also receive unpleasant constant abuse from many strangers too, but that’s not a part of the question. I tried to figure out how my devices sound is modified, I got many recordings to prove that though. So I break down this problem into many pieces eg:

  1. The devices that I use speakers are hijacked and it has to be replaced, but via headphones it’s the same.
  2. Sound is modified by another device in range (don’t know if that’s possible though, but believe that yes).
  3. My network is hijacked, which is most believable break point I believe. I tried many, other network providers, closing ports, hide network over cloudflare warp, use mobile network etcetera.
  4. Youtube, Facebook, Soundcloud and other black list me for some reason and I can’t fix it.
  5. Virus, and I tried many antivirus even bought some.

So none of my tries to fix it worked yet. Not sure if new devices or rewrite os will help, because this is happening for a long time even though I rewrite devices os many times. Of course, it could be that some one access my devices locally from time to time, but anyway. I would like to hear what you think about that and what solutions or suggestions you can suppose to me? Best regards with all love
