Play through your sound card in realtek?

To play audio through your Realtek sound card, ensure that the drivers are properly installed and updated. Access the sound settings on your computer, usually found in the Control Panel or System Preferences, and select the Realtek device as the default playback device. You can then play audio from any application, and it should route through the Realtek sound card. If you're facing issues, check your audio connections and settings for any muted or disabled options.
