# Troubleshoot audio and sound check issues

> Fix problems hearing the interviewer or being heard.

If you can't hear the interviewer or your microphone isn't working, try these steps. Start with the quick checks below.

## Start with a few quick checks

* **Check Bluetooth:** Disconnect any headphones or speakers you aren't using. Your device may be sending audio to them.
* **Turn up your volume:** On your phone, check the **media volume**, which may be separate from your ringtone volume.
* **Try the speaker test:** Reopen your interview link and select **Test Speaker**.

## Allow sound in your browser

If you're using **Chrome on Android**:

**1. Open settings**

Tap the **three dots (⋮)** → **Settings**.

**2. Open sound settings**

Open **Site settings** → **Sound**.

**3. Allow sound**

Make sure sites are allowed to play sound.

## Check microphone permissions

Ribbon needs microphone access for your interview. When prompted, choose **Allow**.

If you previously blocked access, open the site controls beside the address bar and check **Permissions**. Allow **Microphone** access and, if shown, **Sound**, then refresh the page.

## Check your connection

* Temporarily turn off your **VPN** or **Data Saver**, if enabled and you're able to.
* If you're using a work device or office Wi-Fi, try a personal device or another connection, such as mobile data.

## Restart your browser

Close the browser completely, then reopen your interview link and try **Test Speaker** again.

## Clear cache and cookies

In Chrome, go to **Settings** → **Privacy and security** → **Delete browsing data**. Select **Cookies and site data** and **Cached images and files**, then delete the data and reopen your interview link.

## Try a desktop or laptop

If you're still having trouble on a phone or tablet, open your interview link on a **desktop or laptop**.
