The volume of the players is getting adjusted too slow. This may be due to the slow HTTP requests that update the client.

Possible fixes

Sending packets over a socket may be faster than receiving HTTP requests.

For whatever reason coordinates are not sent to the clients after a random amount of time. The issue only seems tp happen when three or more players are online.

Sometimes the player can be heard, even when they're farther than the max_hearing_distance.

When a new user who hasn't yet given access to their microphone joins a room, the user will not answer the call of the other user.I don't know why this is happening yet

For some weird reason IOS devices don't respond to peerJS calls while other devices do. Why? I don't know!

The volume adjustment logic needs to be fine tuned because it isn't working. The volume is not in proportion to the distance between the two players.

This issue may also be linked to #2

A room that doesn't exist shouldn't be joinable. The same is true for creating a room with a name that's already in use. This can be easily fixed by creating a method that fetches all socket.io rooms and checks if the room already exists
