I implementing webRTC with socket.io with for signaling, but earlier as soon as I opened the URL it used to give screeching sound, but then after some research, I added a muted attribute in the local video tag so it got fixed but now when I call someone then both the browser have a high pitched screeching sound(less on macOS chrome and more on android chrome), the code which I using as a basis is from this tutorial, I modified the code on line 148 to have audio: true and the HTML video tag for the local video to have muted, rest of the code is exactly same as the repo.

I have read a lot of articles on it but I am not able to find a solution to the screeching. Any help would be appreciated, Thanks.
