Two "High Definition Audio Device" are installing at Windows boot

My sound card is crashing continuously. I have a feeling it is due to two "High Definition Audio" drivers installing when booting.

In Device Manage > Sound, video, and game controllers I see two "High Definition Audio Device".

How can I prevent two from installing? Under my sound controllers I used to have a Conexant Audio Driver installing automatically. I seemed to have prevented that but still have two.

I tried Uninstalling them both and rebooting but they both return.

Install your computer's conexant audio driver and the 2 audio devices will go back into a single device.

I have 2 Speakers devices in Sound panel

Hello @jwblue,

This might help with further information and diagnostics.

Copy & Paste the following command [ ALL at once ] into a CMD Prompt and press Enter.

If you want a Script with the actual Drivers information let me know.

I hope this helps.

Thank you. What do I do with this information?

Isn't one of those the "high definition audio" from the GPU/APU? All mine have had that if built since 2011 or so. I just disable the graphics card one because I never use it. You can tell which one is which by setting Device Manager to view by connection, instead of by type, then find the audio controller that is on the same "PCI Express Root Port" as the graphics.
