Hello all. I have found a program that does just about all that I want it to do for recording radio to my HD on Linux. KHdRecord at http://software.jodda.de/ . It seems to be a nice program so far. Now to my question. How can I mute specific sound sources on Linux? Such as if I want to record through my Microphone but I want to play a game, or listen to MP3's etc... without hearing the input from the Microphone? I know that in M$ WinDOS I can just click on the mute button for the Micophone or turn the volume all the way down. Also. Is there a way to control the volumes of seperate sound input sources? If needed I have a Creative Labs Sound Blaster Live and am using SuSE 7.3 Professional. Thank you, James Ruhsam Tampa, Fla. usA
