Question Stereo Mix just can't record anything

[JohnnyGui]

I have no idea why this isn't working.

I have disabled all outputs and inputs except for Realtek Digital Output as output and Stereo Mix as input. Both at 100% volume. Checking/unchecking "Listen to this device" doesn't do anything nor does connecting a headset through a jack. Realtek Digital Output shows sound signals but Stereo Mix isn't picking up anything.

I read that having an HDMI cable to a monitor bypasses the onboard soundcard, but shouldn't the onboard soundcard be used if you disable the monitor's speakers? My monitor doesn't even have speakers in the first place (although the output devices show it does because of another similar monitor model with speakers).

Using Windows 20H2.

What can I do to solve this?

What are you even trying to do?
Realtek would be your 3.5 chinch audio port (headset/speakers) so are you trying to record with an external device? If that device needs amplification on the input your standard mobo isn't going to cut it.

I just want to record audio internally from the sound card by using the Stereo Mix which should be possible.
