Stereo Mix can go missing or be hidden in your sound settings due to different reasons.

Let us see how we can address this issue. However, Stereo Mix has often disappeared from the sound settings in Windows. If you want to record all the audio using an application, then you would need to select “Stereo Mix” as the input audio source and not just your microphone. When Stereo Mix is enabled on your Windows PC, it automatically starts using your microphone and listens to other audio channels. If you are listening to music on your speakers and simultaneously talking into your microphone at the same time, you can record both audios at once using Stereo Mix. “Stereo Mix” allows you to record everything coming out of your computer’s audio.

When you get one channel of audio from the app or program running on the PC and another audio channel from your input microphone, Stereo Mix combines the 2 (or more if available) and generates a combined audio stream. The Windows OS perceives this as a (virtual) sound recorder. This feature comes with the most common Realtek audio cards. In layman’s terms, Stereo Mix is the name of the output audio stream when all audio channels have been combined. This is where “Stereo Mix” comes into play.

Using a secondary microphone to capture the audio coming out from your computer’s speakers would not only degrade the audio quality, but it would also involve a lot of digital-to-analog and then analog-to-digital conversions. How is this done? Have they connected another microphone right beside their computer’s speakers? Although this can be done, it is not an ideal situation. You often see videos of streamers or gamers where you can listen to audio being played on their screen, like inside a game, as well as what they are speaking into a Microphone. This post discusses what Stereo Mix is, what its actual purpose is, and how to troubleshoot it if you can no longer see it in your Windows Sound settings.
