Windows 10: No audio on HPAIO Pavillion with B&O

I have an HP AIO that has B&O audio that I am unable to get any audio from. I have tried the troubleshooter but nothing works. I'm a little confused because the speakers are B&O but the device shows Realtek and the driver generic. HP doesn't recognize the problem in the troubleshooter. Also, I tried to reset the BIOS as this is one of the steps in the troubleshooter and I'm looking for version 6 or 7 and I found version F.30 as my BIOS version....odd, right? Then I went to the Computer Management and looked up one of the logs under Audio it shows a 'parent" Screenshot belowOK - i

Connecting B&O H8 Headphones to Surface Book via Bluetooth

My B&O H8 noise cancelling headphones will pair via Bluetooth to my Surface Book but I could not select them as an audio device on the Surface Book. I have seen multiple discussion threads on this same topic but none of those suggestions solved this
problem. After trying numerous different recommendations I found the solution! Simply delete the paired B&O H8 headphones from the Bluetooth devices list, connect the headphones with the USB charging cable to the Surface Book and then add the headphones as
a new Bluetooth device and the Surface Book will recognize the headphones as an audio device.

Hello Janeane,

I had gone through those steps, but I went through them again and the result came to this:

Trouble shooting was unable to automatically fix all of the issues found. More details below:

Audio Device on High Definition Audio Bus doesn't have a driver Not Fixed

And it says the Audio Bus thing twice over. This is the driver I am trying to install but I can't seem to find what driver is supposed to be downloaded for this problem. I have done trouble shooting and restarting over and over again but to no avail.

Thank you for your continued help.
