If your HP Pavilion dv4000's sound isn't working, first check if the volume is muted or turned down in the system settings. You can also try updating the audio drivers through the Device Manager. Additionally, ensure that the correct playback device is selected by right-clicking the sound icon in the taskbar and choosing "Playback devices." If problems persist, consider running the built-in audio troubleshooter in Windows.
