HP PCs - Troubleshooting HDMI Display and Sound Issues (Windows) This document is for HP computers with an HDMI connector. When connecting your computer to an HDMI device, such as a monitor, TV, or surround sound speakers, you might encounter display or sound issues. Before the Windows 10 update, your sound must have been working, but after it, it might have stopped. If your TV audio stops working with Windows 10 HDMI, when you recently updated to new audio drivers. In the Device Manager, you can use the option of “Rollback” to the old audio driver. This should bring the quo-status to the original. By installing the Intel Graphics Driver, the Intel Display Audio Driver is automatically installed. Verify that HDMI audio is your default playback device selected on the Windows. Sound Control Panel. From the Windows desktop taskbar, right-click on the speaker icon to view the menu. From the menu that appears, select Playback devices. HDMI Audio Driver Driver. 2009.10.01: Operating System: Windows Vista, Windows XP 64-bit, Windows 7 64-bit, Windows 7 32-bit, Windows XP, Windows Vista 64-bit.

As you can see, my Panasonic TV does not appear in the playback list of my newly built computer, even with disabled/disconnected devices checked.

I have another computer which does show Panasonic TV there using the same cable, and I can verify that at the time of writing the sound works fine on the other machine. So this is not a TV/cable issue, it's an issue local to my newly built computer and new installation of windows.

Just to confirm if I rightclick the 'digital audio s/pdif' icon above and press 'test' I hear no sound through the TV. Picture comes through fine on the TV it is just an audio issue.

It's also worth mentioning that I can hear sound through my headphones on the troublesome machine and when experiencing these issues they and no other devices were connected to any of the audio jacks on the computer. The HDMI is the only connected audio device and it connects through the graphics card.

My spec is as follows:

graphics card: NVIDIA 9800 GT.
processor: intel i5-7600k.
motherboard: gigabyte z270p-d3.
windows 7 64bit

I firstly installed the high definition audio drivers directly from the gigabyte cd which came with the motherboard. This appears to have installed some software which pops open every time i plug in my headphones to prompt me 'what type of device did you just connect'.

Secondly i did all of the windows updates and because my processor is apparently not supported by windows 7 it fails on the installation of KB4054518 and KB3150513 as well as 2 or 3 security updates. I am not sure how relevant this is to the sound issue? On a side-note I would prefer not to get windows 10 as the last time I used it it would automatically shut down to install updates even if I was in the middle of some unsaved work, and my work requires my computer to run uninterrupted 24/7 which didn't appear to be possible in windows 10.

Thirdly I attempted to install the latest NVIDIA drivers directly from their website and after all of these steps sound still does not come through to the TV.

Interestingly, in the NVIDIA control panel (I think this came with the NVIDIA drivers) it appears to detect 'Panasonic-TV' as a connected device.

Note that the High Definition Audio Controller in the device manager is 'enabled'.

And so is the High Definition Audio Device.

I have also tried every possible combination of turning the computer on and off again with and without the TV off or on and it doesn't seem to make any difference.

If I run the troubleshoot playback devices these are the only two options I get. I'm guessing a third option for hdmi should appear here? either way none of the options help and the next step for the speakers shows:

Hi Biz2risky,

Welcome to Microsoft Answers CommunityForum!

In order to fix your issue, first you need to check if the laptop and computer has HDMI out port?

Step1
Choose the connection for video output. If your computer has an HDMI port, otherwise, you will need to make a few decisions. If your computer has only a single video output, and it will not be used solely with the television, you may want to invest in a new video card. Purchase one with either a DVI or an HDMI output, and install it in an available slot, according the instructions included with it. If you intend to use the VGA output on a single-output or dual-output card to drive the HDMI display, then a special device will be needed to convert between the formats, and the price of the converter is actually about the same price as an entry-level video card that will be easier to use with your TV. In that case, it may be a wise idea to upgrade the card in order to obtain a DVI or HDMI port. However, if your chosen output port is of the DVI variety, an inexpensive DVI to HDMI cable can be purchased to convert your computer's output into the proper HDMI input for your TV.

Step 2

Connect the HDMI cable from your television to your computer. Install the correct adapter or converter for your computer, if necessary. Unless your computer has HDMI output, cords will also need to be connected from the sound card output to the HDMI video cable or adapter, because HDMI carries both video and audio signals.

Step 3

1. 1. Boot your PC, and configure the new display,
2.Go to 'Control Panel' from the 'Start' Menu.
3.Double-click the 'Display' icon and click the 'Settings' tab.

The manual for your HDMI TV will list the screen resolutions it supports, along with the refresh rates.

Configure the resolution in the 'Settings' tab, and then click the 'Advanced' button to set the refresh rate.
If you are using the HDMI TV as the second monitor, you will also have to configure how it is used by Windows, according to the instructions pertaining to your video card. Most cards offer a 'Clone' or 'Mirror' mode, where both screens display the same content. Alternately, the 'Extended Desktop' mode can be used, in which each monitor will operate independently.

Step 4

Reboot your computer to apply the changes, if necessary.
