HP Elitebook 9470m laptop sound issues

[idhanjal]

Very low sound output on HP Elitebook Folio 9470m running Windows 10 Pro Build 19042.1266 (Version 20H2). 

Uninstalled  drivers and rebooted laptop several times but each  reboot yields the same result - the drivers show up again. Can someone help ? Please point me to the right drivers for audio as I cannot find those anywhere on HP website. 

In fact, I see this weird message in  Sound, video and game  controllers  (High Definition Audio Device) - Device HDAUDIO\FUNC_01&VEN_111D&DEV_76E0&SUBSYS_103C18DF&REV_1003\4&9aa5384&0&0001 requires further installation. 

And in  the Audio  inputs and   outputs, under Events section of Speakers and Microphone , there is this message - Device SWD\MMDEVAPI\{0.0.0.00000000}.{a9e28eb3-28d3-4bac-83ae-e8b9043ddbaf} was not migrated due to partial or ambiguous match.

The above two cryptic messages have given me a lot of grief so I would really appreciate some help here. Don't know       what  to make of these.

Hi:

Unfortunately, there are no W10 audio drivers for your notebook.

The only suggestion I can offer would be to see if this W10 audio driver from a newer model notebook also works on yours.

This package contains the driver that enables the IDT High-Definition (HD) Audio in supported notebook models that are running a supported operating system.
