What Causes Stereo Mix to Go Missing on Windows 10?
Windows is constantly getting rid of features they feel are unnecessary and Stereo Mix may just be another one. Still, Stereo Mix is also related to the audio driver you have installed and it may be possible to restore it. There are a few different causes which can cause it to go missing so check out the ones below for more info:
Solution 1: Make Sure Your Microphone is Available for Access
This problem can also appear if your microphone is not available for access. This automatically disables the use of Stereo Mix. This solution is the simplest and it can save you hours of effort so make sure you don’t skip this method when troubleshooting the Stereo Mix missing problem on Windows 10.
