Ok I'm 100% possitive that this has someting to do with sui_scoreboard and/or uteam. Ok when I added Uteam and sui_scoreboard no-one in my server was allowed to use a mic. Wouldn't even display the icon above their head if they were trying to talk. I attempted using sv_voiceenable 0, and sv_voiceenable 0 but neither had an affect. I checked to see that my mic was plugged in, and also that it was functioning(wich it was). So out of desperation, I looked into my addons folder and deleted sui_scoreboard and then uteam from both the lua folder and data folder. After I did that, Our mics were functionable again. Can anyone help with this problem. BTW I'm using svn with ulx and ulib so it's a beta, but this happened before with the stable version too.
