Windows 10: Sound Setting - Stereo Mix - Realteck High Definition Audio is getting in put from Mic...

I don't know how this is happening but I have a newly acquired Dell Optiplex 9020 with a new install of Windows 10 and I cannot get the Stereo Mix in Windows 10 to get the input from the audio stream Youtube for example instead of the microphone. The microphone inputs on both the webcam and the mic input to the sound on MB are both disabled.But when I am recording streaming audio with a application. it only records if the Sound - Playback - Speakers / Headphones are enabled. If I disable those speakers the audio application stops getting sound input. Stereo Mix should keep getting an interna

Stereo mix showing but not showing audio

A potential solution for those who use digital outputs to a separate sound system for your sounds (rather than speakers or headphones), and have tried all the normal suggestions when Stereo Mix shows up on the recording tab, but shows no audio, and programs
such as Audacity won't record a signal.

I use digital optical out from my sound card (Realtek High Definition Audio) to my sound system. There are therefore no speakers connected, and no speakers show in the sound settings. And no audio showing in Stereo Mix.

However, connecting headphones instantly solves the problem - stereo mix shows audio, programs like Audacity can record again (plugging headphones in the headphones jack makes no difference to the digital optical output signal = does not mute it).

I would be really interested to know why Stereo Mix will not show audio if there are no speakers or headphones connected.

Computer won't recognize headset microphone

This is what i see in device manager. Im not sure if the Speakers/Headphones (Realtek High Definition Audio) is the one your saying to disable, as that is what is default in playback devices in the sounds panel.

Setting Stereo Mix as the default recording device and disabling everything else still didnt get the mic working, even when the headset is plugged into the microphone only audio port or the mic + sound audio port.
