Answer

Windows offers its own troubleshooting service that can help you immediately. You can find out how to start the troubleshooting in this FAQ.

Sometimes it is enough to renew or update the driver for everything to work again. Changes can be made in the device manager. You can find instructions on how to do this in this FAQ under Update Driver Software.

On desktop PCs where the signal cable is connected to the internal HDMI or DisplayPort interfaces of the mainboard, loading the default values ("Load Bios Defaults") in the BIOS can also be a reason for missing sound.
⚠️Note⚠️ This step may overwrite any personal settings you have made!
