Windows 10: Stereo mix doesnt show up at all

I've been trying to have audio output in both my TVs and most tutorials use the stereo mix thing, but it doesnt show up at all in my system

Stereo Mix shows up, but doesn't record *anything*

A couple more comments.
The Gigabyte Realtek listed for your motherboard states Win 10 V 2004 supported.
The Gigabyte Realtek listed for my Designare motherboard states support for 20H2 if you want to try it CLICK Its what I'm using and as previously noted Stereo Mix works OK.

I notice "Easytune" is listed as an app for your board. I had an earlier Gigabyte motherboard system that I used in my Recording Studio and was having audio problems. At the time I found out Easytune was a known problem. Uninstalled it and my Recording Studio audio problems went away. Whether this relates to your Stereo Mix recording??

 

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.

 

Stereo Mix Not Showing

It appears that the driver is not recognized by the computer. Your audio chipset drivers may be outdated, that's why Stereo Mix does not appear in the list of devices. We suggest checking the device manufacturer if there are available updates for the drivers.

Once you're done updating the audio chipset drivers, check again if the missing device will appear.

Let us know how it turns out.
