lost audio

[GioPpp]

Good morning,
I own an HP OMEN 15-ek0xxx laptop (serial number Edited) with Windows 11 Pro 24H2.
After an update, the PC no longer recognizes the internal sound card.
In Device Manager, "Intel High Definition DSP" appears under "Other devices" with a yellow triangle.
I have already tried uninstalling and reinstalling the Realtek drivers and Intel Driver & Support Assistant without success.

The device's hardware ID is:
INTELAUDIO\DSP_CTLR_DEV_06C8&VEN_8086&DEV_0222&SUBSYS_878A103C

Could you provide me with the correct driver/SoftPaq package or tell me where to download it from your website?
Thank you very much.

@GioPpp, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It sounds like you’re dealing with a driver issue after a Windows update. Below are a few troubleshooting steps that may help resolve the issue with the Intel High Definition DSP (Digital Signal Processor) not being recognized:

Check Windows Update for New Audio Drivers

Open Windows Settings: Press Windows + I to open Settings.

Go to Update & Security: Select Windows Update.

Check for Updates: Click Check for updates and let Windows download and install any available updates. This may include updated drivers that can resolve compatibility issues after the update.

Update Device Drivers Manually

Open Device Manager: Press Windows + X and select Device Manager.

Locate the Problem Device: Expand the Other devices category. Right-click on Intel High Definition DSP and select Update driver.

Search Automatically for Drivers: Choose Search automatically for drivers and let Windows search for the correct driver.

If this doesn't find the driver, you can try manually installing it.

Download and Install the Latest Drivers from HP

Since the device is an HP OMEN laptop, the most reliable way to get the right driver is from HP’s official support site:

Go to HP Support: Visit the HP Customer Support page at HP Support.

Search for Your Laptop: Enter your laptop model (HP OMEN 15-ek0015nl) into the search bar.

Select Drivers & Downloads: Choose the correct operating system (Windows 11 Pro 24H2).

Download the Audio Driver: Under the "Driver Audio" section, find the latest audio driver, specifically for Realtek or Intel High Definition Audio. Download the appropriate version and install it.

Reboot Your System: After installation, restart your laptop and check Device Manager again.

Uninstall and Reinstall the Problematic Device

Open Device Manager: Press Windows + X and select Device Manager.

Right-click on Intel High Definition DSP: Select Uninstall device.

Confirm Uninstallation: Make sure to check the option that says “Delete the driver software for this device” (if available).

Restart Your PC: After the restart, Windows should attempt to reinstall the necessary drivers.

Manually Install the Audio Driver from Intel

The hardware ID provided (INTELAUDIO\DSP_CTLR_DEV_06C8) indicates that this is an Intel audio device. You can manually download and install drivers from Intel:

Go to Intel's Driver & Support Assistant: Visit Intel's support page.

Run the Detection Tool: Let the tool scan your system for the latest drivers.

Download & Install: Follow the on-screen prompts to download and install the latest driver for your Intel audio device.

Run the Audio Troubleshooter

Open Settings: Press Windows + I to open Settings.

Go to System > Sound.

Run Troubleshooter: Scroll down to Advanced sound options and click on Troubleshoot under the "Output" section.

Check the Sound Settings

Right-click the Sound Icon in the taskbar.

Select Open Sound settings.

Under Output, check if the correct audio device is selected.

Rollback Windows Update

If the issue started right after the update, consider rolling back the update:

Open Settings.

Go to Windows Update > Update History.

Uninstall Updates: Select Uninstall updates and look for the most recent update that could have caused the issue.

I hope this helps.
