Dell XPS 17 9730 Intel Core i9 HDMI Audio Not Working Fix Windows 11

The HDMI-connected monitor or TV connected to your Dell XPS 17 9730 Intel Core i9 produces no audio – the picture displays correctly but all sound comes from the XPS 17 built-in speakers instead of the monitor or TV speakers. Windows audio output device selection and NVIDIA HDMI Audio driver configuration control HDMI audio routing on the XPS 17 9730.

This guide covers Windows audio output device selection, NVIDIA HDMI Audio driver, and sound settings for proper HDMI audio output on the Dell XPS 17 9730 Intel Core i9 in Windows 11.

“XPS 17 9730 connected to 4K TV via HDMI showed picture but no sound. Sound output was still set to laptop speakers. Changed to TV HDMI output in Sound Settings and TV speakers activated immediately.” – Rashidah, content creator from Johor

Why HDMI Audio Does Not Work on Dell XPS 17 9730

Windows does not automatically switch the audio output to HDMI when a monitor is connected. The default audio output remains on the built-in Realtek speakers of the XPS 17 9730. The user must manually select the HDMI audio device in Windows Sound Settings for audio to route through the HDMI cable to the monitor or TV speakers. Additionally, the NVIDIA display driver includes an NVIDIA HDMI Audio driver component that must be installed for the HDMI port to appear as an audio output device in Windows.

• Windows Sound output still set to XPS 17 9730 built-in speakers instead of HDMI audio device
• NVIDIA HDMI Audio driver not installed – HDMI output does not appear in Sound devices list
• HDMI cable not fully seated – picture works but audio connection interrupted
• Monitor HDMI ARC port used instead of standard HDMI input (ARC for audio output requires AV receiver)

Fix 1 – Select HDMI Audio Output in Sound Settings

Click the speaker icon in the Windows taskbar. Click the arrow next to the current output device name. A list of available audio outputs appears. Look for the monitor or TV name (e.g., DELL Monitor, SAMSUNG TV, or similar) marked with an HDMI or Digital Output label. Click it to set as the active output. Audio immediately routes to the HDMI-connected display. To make this permanent, go to Settings – System – Sound and set the HDMI device as Default output. It returns to built-in speakers when the HDMI cable is disconnected.

Fix 2 – Update NVIDIA Driver to Include HDMI Audio

Go to dell.com/support, enter XPS 17 9730 service tag, and download the NVIDIA GeForce RTX 4080 or 4070 driver. NVIDIA display drivers include NVIDIA HD Audio component that adds the HDMI audio device to Windows Sound. If no HDMI audio device appears in Sound Settings after connecting a monitor, the NVIDIA HD Audio driver component was not installed. Reinstall the NVIDIA driver with all components selected to include NVIDIA HD Audio installation.

Enable HDMI Audio Device in Sound Control Panel

Right-click the speaker icon in taskbar and select Sounds – Playback tab. Right-click in the empty area and select Show Disabled Devices and Show Disconnected Devices. If the HDMI audio device appears greyed out (disabled), right-click it and select Enable. Some Windows configurations disable the HDMI audio device by default when no HDMI monitor is connected at boot, requiring manual enablement when connecting a display after Windows has started.

Fix 3 – Set HDMI Audio as Default Communication Device

In the Playback tab of Sound control panel, right-click the HDMI audio device and select Set as Default Device AND Set as Default Communication Device. Setting only as Default Device sometimes leaves communication apps (Teams, Zoom) on the built-in speakers while media audio routes to HDMI. Setting both default properties ensures all audio including video calls routes to the HDMI-connected display speakers when the XPS 17 9730 is connected to a conference room display or TV.

Fix 4 – Check Monitor HDMI Audio Support

Verify the connected monitor has built-in speakers. Not all monitors have audio output capability – many office monitors support HDMI video only. Check the monitor manual for a speaker icon or 3.5mm audio output jack indicating built-in speakers. If the monitor has no speakers, the HDMI audio device appears in Windows as Digital Output with no actual speaker to play through. Use a separate audio output (monitor 3.5mm to speakers) or connect to a TV with built-in speakers for HDMI audio output from the XPS 17 9730.
