ok after several days of surfing other linux forums on the net such as suse ,fedora,mint,debian etc i found a fix for the Microphone problem .I in have a toshiba laptop with a built in microphone that i was unable to use while in online chat rooms or in skype

well here is what i did .Go to synatics package manager or in sabayons case go to RIGO in the search bar there enter GAMIX which is graphical sound mixer alsa dowr sound settings there you will see a way better graph system with many settings including the MICROPHONE Ssetting.I set my toshiba laptop rear mic to input source 1 and the front mic to line the mic works

i have online chat abilities now and i can run skype

to be honest i didnt see much help here on the sabayon forums nor did i ever get a single reply to this problem but it helps to search other linux distros forums as they are always helpful
