Hi, @philbry 

It seems to me that the W10 Intel HDMI audio driver is not installed.

Go to the device manager, click to expand the Sound, Video and Game Controllers device manager category.

You should be seeing two audio devices listed there.

A Realtek HD audio device (controls the PC speakers and headphones)

An Intel HD audio device (controls sound out of the HDMI port).

If there is a Realtek HD audio device and a generic HD audio device, then the W10 Intel HD audio driver needs to be installed.

Let me know what you see under that section of the device manager, and we will proceed from there.

[philbry]

under device manager it lists the realtekHD and intel(r) display audio.

clicking on the intel driver it says device working properly, but under the events tab it says 

Device HDAUDIO\FUNC_01&VEN_8086&DEV_2882&SUBSYS_80860101&REV_1000\4&36cbb407&0&0201 requires further installation.

thanks for your help

You're very welcome, Phil.

Are you sure that DEV_2882 is the correct ID?

Both of the W10 graphics driver files on your notebook's support page show the Intel HD audio driver as HDAUDIO\FUNC_01&VEN_8086&DEV_2883

[philbry]

yes. I copied & pasted everything that was in the information window under the events tab

[Paul_Tikkanen]

OK...

None of the drivers on your notebook's support page have the right W10 graphics driver but I found the one you need from another HP business class notebook.

I have zipped up and attached below, just the HD audio driver you need.

You will need to manually install the driver as follows...

Unzip the file to its folder.  Don't do anything with the files in the folder.

Go to the device manager, click on the Intel HD audio device that needs further installation.

Click on the driver tab.  Click on Update Driver.

Select the Browse my computer for driver software option, and browse to the driver folder you unzipped.

Make sure the Include Subfolders box is checked, and the driver should install.

Then restart the PC and see if you now get audio out of the HDMI port.

[philbry]

windows has determined that the best drivers for this device are already installed

[Paul_Tikkanen]

Sorry that didn't work.

The only other suggestion I can offer would be to right click on the device, select uninstall.

Check the uninstall driver box, restart the PC, and try installing the driver again.

The Intel HD audio device might just be named HD audio device.

But that is the problem...the Intel HD audio device has driver issues, which is why you have no sound out of the HDMI audio device.
