How To Fix Microphone Issue on HP 255 G10 with Windows 11

Select Language:

If your HP 255 G10 running Windows 11 isn’t picking up sound from the internal microphone, you’re not alone. I understand how frustrating it is to see that little yellow exclamation mark in Device Manager next to “ACP DMIC Node,” especially when you’ve already updated your drivers.

Here’s a simple way to fix this issue:

First, double-check that all your drivers are up to date. You’ve already installed the latest Realtek HD Audio driver and AMD chipset updates, so that’s good. Also, run Windows Update and check optional updates; sometimes, newer drivers are available through these updates.

Next, the problem might be with the microphone driver itself, which isn’t coming from the usual sources. Because Windows doesn’t recognize the ACP DMIC Node properly, you’ll need to manually install the correct driver.

Visit the official HP support website and look for the specific driver package for your HP 255 G10 model. Search for “Microphone array driver” or “ACP DMIC Node driver” in the drivers section. If you don’t find the exact package, look for a chipset or audio driver that mentions “converged audio” or “microphone” support.

Once you download the correct driver, follow these instructions:
– Run the installer and follow on-screen prompts.
– After installation, restart your computer.
– Open Device Manager again to see if the issue is resolved. The yellow exclamation mark should disappear.

If you still see the warning symbol after these steps, try uninstalling the device:
– Right-click on “ACP DMIC Node” and select “Uninstall device.”
– Restart your laptop — Windows should attempt to reinstall the driver automatically.

Finally, check your microphone settings:
– Right-click the sound icon in the taskbar.
– Choose “Sound settings” and then click on “Input.”
– Ensure your internal microphone is selected and the volume is turned up.

By manually installing the correct driver from HP’s official site and ensuring your microphone settings are correct, you can usually fix this issue and get your internal microphone working again. If problems persist, reaching out to HP support can provide additional help tailored to your specific model.
