THE PROBLEM

Your $249 microphone keeps losing to your webcam.

macOS gives the mic to whatever plugged in last. Dock your laptop and the webcam wins. Reboot and the display wins. So you dig through System Settings before every call — or worse, you find out mid-recording.

THE MOMENTYour MV7 unplugs mid-callCable snag, dock hiccup, doesn't matter.
THE SAME SECONDSeat 2 takes overYour MacBook mic goes live. The call never skips.
WHEN IT RETURNSThe MV7 reclaims the top spotPlug it back in — it's back on top. With a polite notification.

Other audio tools?Soundstack only sets the system default device — it never touches the audio itself, so it coexists with SoundSource, Loopback, and friends.
