The microphone is not found on my Odys laptop with Windows 10.
I've already tried everything, from "why Cortana can't hear me" to sound settings, but when recording it says that supposedly no recording devices are installed. Everything used to work great. I don't know what to do anymore, I don't even know my way around. But it should work urgently, video conferences on mobile phones are terrible xD
Try to select your output device (speakers / headphones) in "Settings → System → Sound" and which speaker you want to use.
Under "Input" you can select your micro.
Optionally, you can apply more settings under "Advanced sound options" and also press the "Reset" button below and try again to set your settings again.
If that didn't help, unfortunately there's nothing I can do or you have already solved the problem.
