# No audio on a headset

> Fix no-audio and microphone problems on OMNIA softphone calls by checking your output device, audio selection, and browser permissions.

If you can't hear callers or they can't hear you on OMNIA softphone calls, the cause is almost always an audio-device or permission setting on your computer or in your browser — not a fault with the headset itself. Work through the steps below for your symptom.

For desk-phone audio problems, see [Troubleshooting](/omnia/troubleshooting) instead.

## Set the right output device in Windows

When you can't hear audio through a connected headset, confirm Windows is sending sound to the headset rather than another device.

<Steps>
  <Step title="Open the sound device list">
    Left-click the **sound icon** in the Windows taskbar.
  </Step>

  <Step title="Choose the headset">
    Select the connected headset from the drop-down menu. The entry may show **USB** or the brand and model in brackets, depending on how the headset connects.
  </Step>
</Steps>

## Select the right audio device in OMNIA

OMNIA has its own audio-device selector that's separate from your Windows settings.

<Steps>
  <Step title="Open the audio-device list">
    Click the **small arrow** on the headset icon in OMNIA.
  </Step>

  <Step title="Choose your headset">
    Select the correct microphone or headset from the list of audio devices.
  </Step>
</Steps>

## Others can't hear you

If callers can't hear you, work through the microphone checks below.

<Steps>
  <Step title="Check the headset mute button">
    If your headset has a Mute button, make sure it isn't active, and confirm the headset is connected correctly.
  </Step>

  <Step title="Set the default input device in Windows">
    Go to **Start → Settings → System → Sound**. Under **Input**, select your microphone in **Choose your input device**, then speak into it and watch **Test your microphone** to confirm Windows is hearing you.
  </Step>

  <Step title="Allow apps to access the microphone">
    Go to **Start → Settings → Privacy → Microphone**, select **Change**, and turn on **Allow apps to access your microphone**. Make sure **Allow desktop apps to access your microphone** is also set to **On**.
  </Step>

  <Step title="Allow the microphone in Google Chrome">
    In Chrome, go to **Settings → Privacy and security → Site settings → Microphone**. Review your blocked and allowed sites, and change the OMNIA site's microphone permission to **Allow**.
  </Step>
</Steps>

<Tip>
  If the problem continues, run the Windows Sound Troubleshooter. Go to **Settings → System → Sound** — the troubleshooter is listed below the **Input** and **Output** settings.
</Tip>

## Browser remedies

If you use OMNIA in a browser and the steps above don't help, refresh the site's permissions and cached data.

<Steps>
  <Step title="Allow the microphone from the lock icon">
    In the browser address bar on `connect.voxo.co`, click the lock (site information) icon and set **Microphone** to **Allow**.
  </Step>

  <Step title="Clear site data">
    Click the site information icon to the left of the URL, open **Cookies and site data → Manage on-device site data**, delete the entry for `connect.voxo.co`, and reload the page.
  </Step>

  <Step title="Verify operating-system privacy settings">
    In your operating system's privacy settings, confirm your browser is allowed to access the microphone.
  </Step>

  <Step title="Log out and back in">
    Log out of OMNIA and log back in to confirm the warning has cleared.
  </Step>
</Steps>

**Contact support** if you still have no audio after selecting the correct device and allowing microphone access in both your operating system and browser.
