To fix the no sound driver issue on Roblox, start by turning up the volume for Roblox. Right-click the speaker icon in the taskbar, open the Volume mixer, and ensure Roblox is not muted. Adjust the volume to 100 if needed.
Next, check the Roblox settings. Open Roblox and play the game with no sound. Click the Roblox logo, switch to the Settings tab, and make sure the audio is not muted. Also, ensure the volume is not set too low.
If the problem persists, update your audio drivers. You can manually update the audio driver via the Device Manager or use software like Driver Easy. After updating the drivers, restart your PC.
Another solution is to restart the Windows Audio service. Go to Services, find Windows Audio, and restart it. This can fix the “No Output Device” issue.
As a last resort, reinstall Roblox. Uninstall the game, then download and install it again. Ensure your audio device is correctly plugged in and turned on. Restart your computer and disable any antivirus or firewall software that might interfere. Running the Roblox audio troubleshooter can also help.
