# The microphone is blocked in the browser

Start recording stays grey, or MediSync reports that microphone access was denied. How to allow the microphone in the browser and in Windows or macOS.

```text
Microphone access denied. Please allow it in your browser settings.
```

```text
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

**Chrome and Edge**

1. Click the icon at the left of the address bar, before `app.medisync.me`.
2. Set **Microphone** to **Allow**.
3. Reload the page.

**Firefox**

1. Click the microphone or padlock icon at the left of the address bar.
2. Remove the block for the microphone.
3. Reload the page and allow the microphone when Firefox asks.

**Safari**

1. Open **Safari › Settings › Websites › Microphone**.
2. Set `app.medisync.me` to **Allow**.
3. 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.
