Audio muting whenever anyone speaks (one-off occurrence)

[Altimor]

I just played a match where my sound muted whenever anyone talked and I got this spew in the console:

[Assert] C:\buildworker\citadel_rel_win64\build\src\soundsystem\lowlevel\mix.cpp (102) : AssertMsg Failed in function CheckAndSilenceInfiniteBuffer():

This has never happened before and didn't happen the previous game, and I didn't restart my client between those games. Match ID 2357248
