Dell XPS 17 9730 HDMI Audio Not Working Windows 11

You connect your Dell XPS 17 to a TV or monitor via HDMI but no sound comes through – only your laptop speakers play audio. This is a known Windows 11 behavior where the HDMI audio device is not set as default, or the Intel/NVIDIA audio driver needs updating.

This guide covers every fix from changing default audio devices to updating GPU audio drivers, so your external display gets sound correctly.

“Connected my XPS 17 to my living room TV for a presentation and the HDMI had no audio at all. Took me a while to figure out it was a simple default device setting.” – Priya, IT consultant from Singapore

Why HDMI Audio Fails on Dell XPS 17 in Windows 11

The Dell XPS 17 9730 has both an integrated HDMI 2.1 port and four Thunderbolt 4 USB-C ports. When you plug in an HDMI cable, Windows 11 enumerates a new audio device (either Intel Display Audio or NVIDIA High Definition Audio) but does not automatically switch to it unless configured.

• Windows 11 does not auto-switch audio output when HDMI is plugged in
• Intel or NVIDIA HD Audio driver missing or outdated after Windows update
• HDMI device disabled in Sound settings or set as non-default
• Error: No audio output device is installed for HDMI path

Fix 1 – Set HDMI as Default Playback Device

Right-click the speaker icon in the taskbar and select Sound settings. Scroll to Output and click the dropdown – you should see your HDMI or DisplayPort device listed (e.g., Intel Display Audio, NVIDIA High Definition Audio, or your monitor name). Select it as the output device. If it does not appear, right-click the speaker icon, select Sounds, go to Playback tab, right-click in empty space and enable Show Disabled Devices and Show Disconnected Devices.

Fix 2 – Update Intel or NVIDIA Audio Driver

Open Device Manager (Win + X), expand Sound, video and game controllers. Look for Intel Display Audio or NVIDIA High Definition Audio. Right-click and select Update driver. Choose Search automatically. If no update is found, go to dell.com/support and download the latest audio driver for XPS 17 9730 Windows 11.

Registry Check for HDMI Audio

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render and verify the HDMI audio endpoint is not disabled. If all entries show State = 1 (disabled), re-enable the HDMI device from Sound settings.

Fix 3 – Restart Windows Audio Service

Press Win + R and type services.msc. Find Windows Audio, right-click and select Restart. Also restart Windows Audio Endpoint Builder. After restarting both services, unplug and re-plug the HDMI cable – Windows 11 should detect the audio device fresh.

Fix 4 – Reinstall NVIDIA or Intel HD Audio Driver

In Device Manager, right-click Intel Display Audio or NVIDIA High Definition Audio and select Uninstall device. Check Delete the driver software. Restart the laptop. Windows will reinstall the driver automatically on next boot. If not, download from Dell Support and install manually.
