# Extension activity 2: Adding sound asset to the app
For an additional enhancement, let's integrate a sound asset into the app. Follow these straightforward steps to incorporate a sound file along with the button component.
1. Navigate to the left panel (Panel 1) and click on the **`Media`** tab. Drag and drop the **`Sound`** component onto the screen. Note that the sound component is non-visible, so you won't see any changes on the screen.
2. Upload a **WAV** sound file, similar to how you uploaded the image file.
> Locate the sound file (**`switch-1.wav`**) within the Media folder.
3. Click on **`Sound1`** in the **`Components`** tree. From the **`Properties`** panel, select the uploaded sound file as the **`Source`**.
4. Switch to the **`Blocks`** tab and click on **`Sound1`**. Drag the **`call Sound1.Play`** block.
5. Move the **`Play`** block inside both the **`if`** and **`else`** parts of the existing code. The final code should resemble the image below:
