Windows 11
The HP ProBook 465 G11 is a business laptop with the AMD Ryzen 5 7530U processor. A missing audio driver is a common issue after a Windows update or fresh OS installation, resulting in no sound from speakers or headphones and a yellow warning sign on the audio device in Device Manager. The ProBook 465 G11 uses a Realtek High Definition Audio codec, and the fix is straightforward.
Fix 1 — Run the Audio Troubleshooter
Right-click the speaker icon in the system tray and select Troubleshoot sound problems. The Windows 11 audio troubleshooter detects missing or corrupted audio drivers and often resolves the issue automatically by reinstalling the generic driver. If the fix is temporary and audio fails again after a restart, proceed with Fix 2.
Fix 2 — Install HP-Specific Realtek Audio Driver
The ProBook 465 G11 requires an HP-validated Realtek driver, not the generic driver from Realtek directly. Visit HP Support, enter your model number, go to Drivers & Software, and download the Realtek Audio Driver under Audio. Install it and restart.
- Do not use the Realtek website directly — HP customizes the audio driver for ProBook hardware
- After installing, open Sound settings and verify the correct output device is selected
- Set Realtek HD Audio as the default device for both playback and recording
Fix 3 — Reinstall Windows Audio Service
Open Services (Win + R, type services.msc), find Windows Audio and Windows Audio Endpoint Builder. Right-click each and select Restart. Ensure both are set to Automatic startup type. A corrupted audio service state is a common cause of the no-sound issue even when the driver appears installed.
Fix 4 — Check AMD Audio Device in Device Manager
AMD Ryzen platforms include an AMD High Definition Audio device for HDMI audio output. In Device Manager under Sound, video and game controllers, you may see both Realtek High Definition Audio (for speakers/headphones) and AMD High Definition Audio (for HDMI). Ensure neither has a yellow warning icon. If both are missing, update the AMD chipset driver from the AMD Support page.
