HP Envy HDMI Audio Not Working on Windows 11: Display Driver Fix Guide

HP Envy laptop HDMI audio not working on Windows 11? The external monitor or TV connected via HDMI shows video correctly but has no sound, the monitor speakers are silent, or Windows shows no HDMI audio device in Sound Settings. HP Envy 13, 14, 15, and 17 models route HDMI audio through the Intel HD Graphics or AMD Radeon display driver. When Windows 11 updates the graphics driver to a version that changes the audio endpoint behavior, HDMI audio disappears entirely or requires manual selection as the default output device every time the HDMI cable is reconnected.

Why HP Envy HDMI Audio Stops Working on Windows 11

HDMI audio failure on HP Envy has specific causes related to how Windows 11 handles display-linked audio:

• HDMI audio device not set as default output — the most common cause; Windows defaults back to the laptop speakers after HDMI disconnect, and does not automatically switch back when HDMI reconnects
• Intel or AMD display driver update changed audio endpoint — the display driver includes an audio component; version updates can change the audio device identifier, causing Windows to forget the previous default setting
• Monitor HDMI input not set to active input on the TV or monitor side — some TVs require manual input selection; the audio may be playing to the HDMI device but the TV input is set to a different source
• HP Envy USB-C to HDMI adapter audio routing — on HP Envy models that output HDMI through USB-C (Thunderbolt), the USB-C audio driver handles HDMI audio separately from the display driver

Check Sound Output Device Selection First

Click the speaker icon in the taskbar → click the arrow next to the volume name to expand output selection. Look for an entry like Display Audio (Intel), HDMI Audio, or your monitor’s name. If it appears, click it to select it. If it does not appear at all, the audio driver is not detecting the HDMI-connected device.

Fix HP Envy HDMI Audio on Windows 11

Step 1: Set HDMI Audio as Default Output Device

Right-click the speaker icon → Sound Settings → scroll down to More Sound Settings → click it. In the Playback tab, look for Display Audio, HDMI Sound, or your monitor name. If it shows as disabled (greyed out), right-click → Enable. Right-click again → Set as Default Device. Click OK. Sound should now play through the HDMI-connected display. If the device does not appear in this list, the graphics driver is not publishing it.

Step 2: Update Intel or AMD Display Driver

Go to HP Support, enter your HP Envy serial number, go to Drivers & Downloads → Display/Graphics. Download and install the Intel Graphics or AMD Radeon driver for your specific Envy model. After installing and restarting, reconnect the HDMI cable and check Sound Settings → More Sound Settings → Playback — the HDMI audio device should now appear and can be set as default.

Step 3: Disable and Re-enable HDMI Audio in Device Manager

Open Device Manager → Sound, video and game controllers. Look for Intel Display Audio or AMD High Definition Audio Device. Right-click → Disable device → wait 5 seconds → right-click → Enable device. Reconnect the HDMI cable. This forces the audio endpoint to re-register with Windows and often makes the HDMI audio device reappear in Sound Settings.

Per Anna P., who is a Teacher using an HP Envy 15-ep: “I use a projector in class via HDMI and the sound stopped going to the projector after a Windows 11 update. The projector was in the Playback devices list but not set as default. Right-clicking it and setting as Default Device fixed it, but it reset itself after every restart. The fix was to disable and re-enable Intel Display Audio in Device Manager — after that, Windows remembered my HDMI audio choice across restarts.”

Frequently Asked Questions

HP Envy HDMI audio device not appearing in Sound Settings — fix?

Open More Sound Settings, Playback tab, right-click anywhere and check Show Disabled Devices and Show Disconnected Devices. If the HDMI audio device appears greyed out, right-click it and Enable. If it does not appear even with disconnected devices shown, update the Intel or AMD display driver from HP Support.

HP Envy HDMI audio works once but resets to laptop speakers after restart — fix?

Disable and re-enable Intel Display Audio in Device Manager (Sound, video and game controllers). This forces a fresh registration. After re-enabling, set the HDMI audio device as default again. The driver re-registration causes Windows to remember the setting persistently.

HP Envy USB-C to HDMI adapter audio not working — different issue?

Yes. USB-C to HDMI adapters on HP Envy use a USB audio device endpoint rather than the display driver audio. Check Sound Settings for a USB Audio Device entry when the adapter is connected. The driver for USB-C audio comes from the Thunderbolt driver, not the display driver — update the Intel Thunderbolt driver from HP Support.

HP Envy HDMI to TV — picture works but TV speakers are silent — why?

Check the TV’s input audio settings. Some TVs have a separate audio input selection that must be set to HDMI or PCM. Also check Windows Sound Settings and make sure the TV is set as the default output device, not just visible in the list. The TV volume must also not be muted or set to zero.

Conclusion

HP Envy HDMI audio not working on Windows 11 is fixed by setting the HDMI audio device as the default output in Sound Settings, then updating the Intel or AMD display driver from HP Support. Disabling and re-enabling the Intel Display Audio device in Device Manager resets the audio endpoint registration and causes Windows to remember the HDMI audio default across restarts.
