Questions: 4 Multiple Choice 2 points If your sound isn't working even after checking the volume and speaker connection, what else can you try? Restart the Wi-Fi router Check your computer's battery level Change the wallpaper Update the sound drivers in Device Manager

The answer is the fourth one: Update the sound drivers in Device Manager.

Explanation for each option:

• Restart the Wi-Fi router: This option is unrelated to sound issues. The Wi-Fi router controls internet connectivity, not audio output, so restarting it would not affect sound problems.

• Check your computer's battery level: While a low battery might cause some performance issues, it is unlikely to directly affect sound output unless the device is in a power-saving mode that disables sound. However, this is not a common cause of sound issues.

• Change the wallpaper: Changing the wallpaper is purely a visual change and has no impact on sound functionality. This option is irrelevant to solving sound problems.

• Update the sound drivers in Device Manager: This is a relevant and effective step. Outdated or corrupted sound drivers can cause audio issues. Updating the drivers can resolve compatibility problems and restore sound functionality.

In summary, if your sound isn't working, updating the sound drivers in Device Manager is a logical step to troubleshoot and potentially resolve the issue.
