"The -uN switch sets the mute setting, where N = 1 is on, N = 2 is off." mIRC help.
The problem is, I can easely mute with /vol -uv 65000, but I can't unmute using neither of the described switches for the /vol command, (wmpvuN), what am I doing wrong.
Ps. is of course running newest version of mIRC, and using WinXP.
