ASUS TUF Dash F15 FX517 Intel Core i7-12650H HDMI No Audio Fix

The ASUS TUF Dash F15 FX517 includes an HDMI 2.0b port for connecting to external monitors, TVs, and projectors. When HDMI video works but no audio comes through the connected display — or the HDMI audio device does not appear in Windows sound settings — it creates a frustrating experience during presentations and media playback.

This guide explains how to fix HDMI no audio on the ASUS TUF Dash F15 FX517 with the Intel Core i7-12650H processor.

Why HDMI Audio Is Not Working

• Windows audio output device still set to laptop speakers instead of HDMI
• HDMI audio device disabled in Windows Sound settings
• NVIDIA or Intel HDMI audio driver not installed
• HDMI cable does not carry audio (some cables are video-only)
• TV or monitor HDMI input set to a mode that mutes external audio

Step-by-Step Fixes

Fix 1: Set HDMI Audio as the Default Playback Device

Windows does not always switch the audio output automatically when HDMI is connected:

1. Right-click the speaker icon in the taskbar and select Sound settings.
2. Under Output, click the dropdown and select HDMI Audio or Digital Output (HDMI).
3. Play audio and listen from the connected display speakers.

Fix 2: Show Disabled Devices in Sound Settings

The HDMI audio device may be hidden because it is disabled:

1. Press Win + R, type mmsys.cpl, and press Enter to open the classic Sound panel.
2. Right-click anywhere in the Playback tab and check Show Disabled Devices and Show Disconnected Devices.
3. If the HDMI audio device appears greyed out, right-click it and select Enable.
4. Right-click it again and select Set as Default Device.

Fix 3: Update the NVIDIA HDMI Audio Driver

On the TUF Dash F15, HDMI audio is handled by the NVIDIA HDMI Audio driver when the dGPU is the active output:

1. Open GeForce Experience and check for driver updates.
2. Install the latest NVIDIA driver with the Clean Install option to ensure the HDMI audio component is included.
3. Restart and test HDMI audio.

Fix 4: Test with a Different HDMI Cable

Older or cheap HDMI cables may carry video but not audio. Try a different HDMI 2.0 cable and test whether audio appears in Sound settings. HDMI 1.4 cables also support audio, so any cable rated 1.4 or higher should work.

Fix 5: Check the TV or Monitor HDMI Audio Settings

Some displays have a setting that routes audio from the HDMI input to internal speakers only when a specific setting is enabled. Check the TV or monitor input settings and look for an HDMI audio or ARC setting. Ensure audio is set to receive from the connected HDMI source rather than from an optical or analog input.
