Audio bug ( sym?)

im not sure if its for sym only or for everyone but i noticed an annoying buzzing sound every now and then through out the match, it might be a bugged turret or something but im not sure because i didnt pay much attention to who i was and when i heard it but i kept hearing it thru several maps

Hello MadAlice.
Were you able to fix it? I am having the same problem right now and cant figure out how to fix it.
