I'll take this opportunity to quickly grab an engineer to try and get an answer:
Is the sound bug which makes the entire game sound like you're listening through 20 tin cans something know and actively worked on? I don't see much about it around here but the stray comment or 2-3 does tell me it's a recurring problem.
Well you got the wrong engineer, I don't touch sound stuff. I did forward an issue mentioned on this sub a week back where the sound was messed up during the first ~30s of a match, if that's what you mean then it's tracked and being investigated.
