I am using Windows 10. And after the upgrade, My Stereo mix does not work. My intention are to share my video and audio together on Skype, plus I should talk at the same time. Also I want to record games/ or my screen with audio and commentary at the same time while playing or using. For that I need the Stereo Mix to work. I tried to put Stereo Mix to my Default Device but it says that it's 'Currently Unavailable'. Those bars does not show up when I put it to default device or something else. BUT when i disable microphone it works and when I try to enable microphone it says again the same thing, "Currently Unavailable". Then i got to disable Stereo mix and microphone and then put again the mic on and set it as default device and then the microphone works again. I need to get them both working at the same time. Due to this Error, every time I try to change the audio setting on Skype, by going to Tools>Options>Audio Settings>Microphone>(Selecting)StereoMix>Save. Doing so, after this I CANNOT place a call on skype. It automatically Cancels down within 2 Seconds. BUT, if I change back to the Microphone option on Skype audio Settings, the call easily get through without any sort of problem. So I figured out that MY STERIO MIX is causing the MAIN PROBLEM. I will be grateful, if any of you can assist me to solve this problem Step By Step. Thanks.
