Up until now I have been able to record from my computer (like recording audio from YouTube). I would change my setting in the recording device to do this.
Yesterday, my computer received a Windows update and I can no longer use that feature. Is there a solution to this?
Selecting WASAPI as the audio host should enable you to record what you hear, regardless of Windows updates.
If you want to use Stereo-Mix/WaveOut instead, you may have to re-enable those after a Windows update, see …
