A-R-Wow I thought I was going crazy, I heard the same noise on granary earlier today while playing a lobby. I shrugged it off because I could not hear the noise on my local client when I loaded cp_granary.
I just heard the noise on cp_granary too.
DamnEasyTry snd_refresh, and try to record it so we can hear it
I tried snd_refresh, and that didn't solve the problem; I'll try to record the noise later.
ShunRaise snd_mixahead?
Raising snd_mixahead to the default value of 0.1 didn't fix the issue.
