Mikrofonzugriff verweigert
The browser does not release the microphone. The recording dialog shows no message in this case: the Start recording button stays grey and nothing can be chosen under Select Microphone. The messages above appear when you use the microphone in the documentation, for example to change it by voice. The second one currently appears in German, also in the English interface.
Allow the microphone in the browser
- Click the icon at the left of the address bar, before
app.medisync.me. - Set Microphone to Allow.
- Reload the page.
- Click the microphone or padlock icon at the left of the address bar.
- Remove the block for the microphone.
- Reload the page and allow the microphone when Firefox asks.
- Open Safari›Settings›Websites›Microphone.
- Set
app.medisync.meto Allow. - Reload the page.
Allow the microphone in the operating system
If the browser allows the microphone and Start recording still stays grey, the operating system often blocks the browser.
- Windows: open Settings›Privacy & security›Microphone. Turn on microphone access and allow it for desktop apps.
- macOS: open System Settings›Privacy & Security›Microphone and turn on your browser. Then restart the browser.
Other causes
- No microphone detected: check the cable or Bluetooth connection. A headset appears only once it is connected.
- Another program uses the microphone: close video calls or dictation programs and reload the page.
- Wrong device selected: in the recording dialog, choose the right microphone under Select Microphone. The bars next to it show whether sound comes in.
