# Audio/Microphone Issues
All Vagon computers are preconfigured to support audio and microphone devices for both input and output.
However, configurations can become outdated over time, and usage-related changes may also lead to misconfigurations that affect audio and microphone support.
If you are experiencing audio or microphone issues inside your Vagon computer, follow the steps below in order.
## 1. Enable Audio and Microphone
Open the Vagon dock menu — the Vagon icon at the top of your Vagon desktop — and make sure the audio and microphone toggles are enabled.
## 2. Check the Selected Audio and Microphone Devices
In the dock menu, check the selected Audio and Microphone devices, and make sure the options starting with "Default" are selected.
> Some external microphone & audio devices may be listed in different formats. If you are using additional external devices, try different combinations of the microphone and audio input options.
If you can see the correct options here, move on to the next step; otherwise, continue with the steps below.
## 3. Check Browser Permissions
When connecting to your Vagon computer from a browser, you must grant audio and microphone permissions to use these devices.
When connecting through the Vagon Desktop Application, you must also grant microphone and audio permissions in your local device settings so that Vagon can access them.
If these permissions are not granted, the system cannot enable audio and microphone support.
## 4. Verify Input and Output Device Selection
If all the steps above are correct but the issue persists, go to the **System > Sound** settings page to check the Windows device selections.
* **Output (Playback) device:** Vagon Audio Driver
* **Input (Recording) device:** Vagon Audio Driver
To set a device as default, select it from the list and click **Set Default**.
## 5. Check Application Level Configurations
By default, applications use the System Default audio and microphone configuration. However, some applications (e.g. Zoom, Slack) can override this and select different devices on their own.
When this happens, you will still hear system sounds and audio from websites, but you cannot hear the application's audio, or your voice is not delivered through it.
To configure application-specific Audio & Microphone selections, go to the application's settings, open its Audio and/or Microphone preferences, and make sure that **Headphones (Vagon Audio Driver) is selected as the Audio device** and **Microphone Array (Vagon Audio Driver) is selected as the Microphone device.**
### 6. Open the Sound Settings Window
Open the Control Panel and go to **Sound**. A window with the **Playback**, **Recording**, **Sounds**, and **Communications** tabs will appear.
* The **Playback** tab must contain the **Speakers** — Vagon Audio Driver *(Default Device)* item, and this must be the selected device, regardless of any others in the list.
* And, the **Recording** tab must contain the **Microphone Array** — Vagon Audio Driver *(Default Device)* item, and this must be the selected device.
