Mic's freezing in CS:S?


Support Death Metal.
Ever since the new update, randomly..In the middle of my game, everyone will show up on my screen using a mic, even Terrorists.

As Jailers know, only eGO Admins can use mic as a terrorist on our servers, so something isn't right here. No one else notices, so I'm left to feel like a dumbass. They don't emit any sound, it's nothing, literally nothing.

Anyone got any ideas of what this could be?
Much appreciated,
