If RadMyk can't hear you or says the mic is unavailable, check the permission, make sure no other app is using the mic, and confirm the right device is selected.
Symptom: You press your shortcut but nothing records, or RadMyk says the
microphone is unavailable.
Work through these
Permission. Make sure RadMyk is allowed to use the mic:
macOS: System Settings → Privacy & Security → Microphone → RadMyk on.
Windows: Settings → Privacy & security → Microphone → RadMyk on.
If you just granted it, restart RadMyk.
Another app has the mic. A browser call, a meeting app, or Voice Memos can
hold the microphone. Close it and try again.
Right device selected. In Settings → Microphone, confirm the device
you’re actually speaking into is chosen - not a disconnected headset.
Muted or unplugged. Check your system volume controls and that any
external mic is plugged in and not muted.
