Dell Vostro 5635 AMD Ryzen 7 7730U HDMI Audio Not Working Fix Windows 11

The HDMI-connected monitor or TV on your Dell Vostro 5635 AMD Ryzen 7 7730U produces no audio – sound continues from the laptop speakers instead of the HDMI-connected display, or the HDMI audio device does not appear in Windows Sound settings. Selecting the correct HDMI audio output device in Sound settings restores audio to HDMI-connected displays on the Dell Vostro 5635 AMD.

This guide covers HDMI audio output selection, AMD audio driver updates, and default playback device configuration for the Dell Vostro 5635 AMD Ryzen 7 7730U in Windows 11.

“Vostro 5635 AMD HDMI audio not working for TV connection in meeting room. Sound stayed on laptop. Right-click speaker icon, opened Sound settings, changed output to AMD HDMI Audio. Sound went to TV immediately. Just a setting, not a driver issue.” – Norzalina, operations coordinator from Shah Alam

Why HDMI Audio Does Not Work on Dell Vostro 5635 AMD

Windows 11 does not automatically switch the default audio output to HDMI when a display is connected via HDMI. The laptop Realtek audio device remains as default playback output regardless of HDMI connection state. To hear audio through the HDMI-connected TV or monitor, the user must manually select the HDMI audio device (typically listed as AMD High Definition Audio Device – HDMI or similar) in Windows Sound settings as the default output. The AMD Radeon driver package for the Vostro 5635 AMD Ryzen 7 7730U includes the AMD High Definition Audio driver that enables HDMI audio output – if this driver is not installed, the HDMI audio device option does not appear in Sound settings.

• HDMI audio device not selected as default output – Windows keeps laptop Realtek as default
• AMD High Definition Audio driver not installed – HDMI audio device absent from Sound settings
• HDMI cable does not support audio (older HDMI 1.0-era cables may not carry audio signal)
• TV or monitor HDMI input not set to receive audio from connected device (TV source audio setting)

Fix 1 – Select HDMI Audio as Default Output

Right-click the speaker icon in the Windows taskbar and select Sound settings. In the Choose where to play sound section, look for AMD High Definition Audio Device or HDMI/DP Audio in the output device list. Click it to select it as the active output. Test audio by playing a YouTube video – sound should now come from the HDMI-connected TV or monitor speakers. If the HDMI audio device is not visible in the list, click the Show more output devices link below the visible list. Also check that the TV or monitor audio source is set to the correct HDMI input (most TVs have multiple HDMI inputs and audio may need to match the input number the Dell Vostro 5635 is connected to).

Fix 2 – Update AMD Radeon Driver via Dell SupportAssist

Open Dell SupportAssist and install AMD Radeon driver updates. The AMD Radeon driver package for the Dell Vostro 5635 AMD Ryzen 7 7730U includes the AMD High Definition Audio driver as a component – this is separate from the Realtek HD Audio driver for the laptop’s built-in speakers. After AMD Radeon driver update and restart, connect the HDMI cable. Open Sound settings and check the output device list for AMD High Definition Audio Device, AMD HDMI Audio, or similar. The AMD HDMI audio entry appears only when an HDMI cable is actively connected to a powered display – it disappears from the list when the HDMI cable is disconnected, which is normal behavior indicating the audio device requires an active HDMI link to appear.

Check Sound Control Panel Playback Devices

Right-click speaker icon – Sound settings – scroll down – More sound settings. In the Playback tab of the Sound control panel, right-click any empty area and ensure Show Disabled Devices and Show Disconnected Devices are checked. This reveals all audio output devices including those that Windows has automatically disabled or hidden. If AMD HDMI Audio appears but shows as Disabled, right-click it and select Enable. Right-click it again and select Set as Default Device. After setting as default, click Test to verify audio plays through the HDMI-connected display on the Dell Vostro 5635 AMD Ryzen 7 7730U.

Fix 3 – Reinstall AMD High Definition Audio Driver

Open Device Manager – Sound, video and game controllers. If AMD High Definition Audio appears with a warning icon, right-click – Uninstall device. Check Delete the driver software checkbox. Click Uninstall. After uninstall, go to Action menu – Scan for hardware changes. Windows reinstalls the AMD HD Audio driver. If the HDMI audio device still does not appear after driver reinstall, go to Dell SupportAssist for the AMD Radeon Graphics driver which includes the HD Audio component. The AMD HD Audio driver reinstall resolves cases where a Windows Update replaced the AMD-specific HD Audio driver with a Microsoft generic audio driver that does not expose the HDMI audio output for the Dell Vostro 5635 AMD platform.

Fix 4 – Auto-Switch HDMI Audio on Connection

Windows 11 can be configured to automatically prompt to switch audio output when a new audio device is connected. Go to Settings – System – Sound – scroll down to Advanced settings – More sound settings. In Sound control panel – Playback tab – right-click AMD HDMI Audio device – Properties – Advanced tab. Check Allow applications to take exclusive control and Give exclusive mode applications priority. Additionally, some users install apps like Sound Switcher (free) to create automatic rules: when HDMI audio device appears, switch default output to it; when disconnected, revert to Realtek laptop speakers. This eliminates the manual default device switch step each time the HDMI cable is connected to a TV or external monitor from the Dell Vostro 5635 AMD.
