Realtek Audio Line In (blue) detected as Microphone, Breaks Audio and Forces System Restore to Fix

With the newest iterations of Windows 10 my onboard Realtek HD Audio "Line In" input (blue 3.5mm audio input) is detected as a microphone. I know this because of the Microphone icon appears in the tray when I plug it in and disappears when I unplug it. I have NO microphone plugged into my PC at all. I use the audio input to listen to my stereo receiver (mainly LPs) while computing. The sound outputs via my NVidia RTX2070 HDMI High Definition Audio to my monitor which has a soundbar attached via optical. This setup worked flawlessly until recent Windows 10 updates introduced the microphone always on with the icon feature. The blue 3.5mm onboard Realtek HD Audio Input is the only Realtek input/output port in use. No microphone is plugged into either rear or front (pink) microphone input port.


With this new "microphone" situation, any website browsed to can activate the microphone (which I don't have as stated). One site of note is Netflix. If I go to one of these sites that wants to activate my microphone (that I don't have):


1) my display blacks out for a second, then comes back on with a notification that the site has accessed my microphone.


2) my music that I was playing through my Realtek Audio Line In goes silent.


From that point on I cannot get my Audio In music to play through my soundbar. The Audio Line In is working because the audio meter in the Sound settings is still pulsing. No reboots nor enabling and disabling Sound settings can get the "Line In" sound playing back to the soundbar. System sounds and web site videos can still be heard.


Essentially a microphone (that I don't have) event breaks the Line In audio from being "heard" from that point on. The only way I have figured to get the ability to hear my receiver on my PC out to my soundbar is to run System Restore to my last restore point.


Is there a workaround? The blue Realtek Audio Line In should not be detected as a microphone and utilized as such. This needs to be fixed ASAP!
