When I try to use stereo mix to play music on Skype calls, my friends can barely hear it on max volume. My stereo mix is enabled and selected as my recording device on Skype. The green bar next to the stereo mix icon doesn't move when i play music. Any help? I have a HP Pavilion Slimline s5-1430d. http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03518242
