macOS Catalina removed the toggle "Use ambient noise reduction" and turned it on by default.
I read on other sites that this is a bug, but until the toggle returns, does anybody know if there is a defaults write for turning the noise reduction off?

It seems like this setting is enabled by default in macOS Catalina, but I still hear noise. My best solution was to buy a USB/audio hub. It was cheap.
I compared the files from Gsazraetr response, and only found a difference in lines 50-55 of com.apple.audio.SystemSettings.plist, which was missing the segment below in the "Reduction On" version:
<dict> <key>master data source value</key> <integer>1769173099</integer> <key>uid</key> <string>AppleHDAEngineOutput:1F,3,0,1,1:0</string>
</dict>But this file did not exist in my Catalina anyway.
