No audio HDMI output

[maryliz62]

Since installing Windows 10, I no longer get audio output through HDMI.  The HDMI option does not even show up in the sound settings.  Have been unable to find the proper driver to enable HDMI audio.  Can anyone help?

Hi:

What is the full model number or product number of your dv6?

The product number can be found on the same sticker as the serial number.

You're very welcome.

Try this...

In the device manager, under the sound, video and game controllers device manager category, you should see two HD audio devices.  One IDT HD audio device and one plain HD audio device.  The plain HD audio device is the Intel HDMI audio device that needs to have the driver installed.

Since the W10 Intel graphics driver is working fine, and you get video out of the HDMI port, we are going to install just the Intel HDMI Audio portion of the Intel graphics driver, so as not to mess with the video portion of the driver.

Here is the problem...there is no W10 HDMI audio driver for W10 for the Intel HDMI audio, so we will have to use the W7 driver from your notebook's support page and get it out of the W7 graphics driver.

First download and install this free file utlility.  The 2nd link at the top of the page is for 64 bit.

http://www.7-zip.org/

After you install 7-Zip, download and save, but do not run this Intel graphics driver.

This package contains the driver for the Intel Graphics Media Accelerator HD in the supported notebook/laptop models.

http://ftp.hp.com/pub/softpaq/sp46501-47000/sp46533.exe

Once you have saved the graphics driver file, right click on it and select 7-Zip from the list of items on the menu.

Have 7-Zip Extract to:  and let it extract the file into its folder name (sp46533).

After 7-Zip does its thing, go to the device manager and click on that plain HD Audio device (not the IDT one).

Click on the driver tab.  Click on Update Driver.

Select the Browse my computer for driver software option, and browse to the driver folder 7-Zip created.

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

Then restart the PC, and see if you now have audio and video via the HDMI out port.

Sorry about last reply, I had not actually installed 7-zip.  I did that and the extraction of the sp file, however, when I did the driver update and directed search to that folder it came back with latest driver installed.

If I uninstall the driver from device manager, will I be able to add by going through device manager and directing it to that folder?

Hi:

Try this...normally the driver installs the way I provided the instructions, but one other person reported it didn't work and we had to do this...force the Intel driver to install.

Go to the device manager, click on the plain HD audio device again>driver tab>Update Driver>Browse my computer...

But this time, at the bottom of that window, select the Let me pick from a list of device drivers on my computer.

Click on Have Disk and browse to the driver folder 7-Zip created>ibxHDMI folder>IntcDAud file, and see if the driver installs that way.

Then restart the PC.
