For some time I noticed that the radio located inside the chat does a problem similiar to lag, but it's not a problem of the radio. It only happens when you place the radio in the player inside the chat. Basically every 1-2 minutes audio goes back to 2 seconds before. Is there a fix for that? Thanks."
