Kortek Audio

Pick your mic and speakers once. Kortek Audio keeps them as the Windows default and holds your mic volume, even when Discord, Zoom, games or a USB replug try to change them.

Download for Windows Windows 10 / 11 · free
Kortek Audio window: microphone and output pickers with lock boxes and a volume slider

Run the download once: it installs itself for your user (no admin needed), starts with Windows and sits in the tray. Close the window and it keeps working.

Windows may say "Windows protected your PC" the first time because the app is new. Click More info → Run anyway.

Remove it any time from Settings → Apps → Kortek Audio.
