Audio crackling on some setups as snd_mixahead default value is too low

[street]

For anyone trying to fix this issue, press F7 to open the console then increase the value of snd_mixahead at around 0.05. If the issue still persists, keep increasing the value just a little bit until the audio stopped crackling. Setting it too high would introduce more audio output latency. I use 0.05 and it fixed the problem in heavy fights.
