ok i just set my brothers new computer up. i refurbed an old HP with a 1.1G celly. its a pretty solid system its running 2k. heres the actual question.i ran a line in for audio from the tv. to get tv sound. is there a way i can setup some sort of key command to mute the line in so he can cut off the tv sound without having to open up the volume control??

mabey a macro but that would probally require a program to run in the background all the time

i am not too experianced with macros though so i couldnt tell you a good program
