HDMI Shows Video But No Sound.

[Rasheed786]

Recently I bought this Laptop but when I tried to plug my HDMI cable to my TV I get video but no sound. I have gone into my Playback devices and the HDMI is not shown in the playback devices, clicked show disconnected and disabled devices it didn't work. I get the plug-in sound when I connect HDMI. I downloaded the sound drivers from the HP page for my laptop it also didn't work. My Laptop's Drivers are all updated to the latest version and also the windows. What should I do? Please help?

Thank you for posting on the HP Support Community.

When you use HDMI to connect your display, you need to adjust some settings through Windows to hear sound through the display as described in Selecting HDMI sound as the default output audio device. Also please refer to this HP community post: Click here
 

See if this works:

Download and save, but do not run this Intel HD graphics driver from your notebook's support page.http://ftp.hp.com/pub/softpaq/sp72001-72500/sp72370.exe

Then download and install this free file utility.  The 2nd file on the page is for 64 bit. http://www.7-zip.org/

After you install 7-Zip, right click on the graphics driver file you downloaded and saved.

Select 7-Zip from the list of items.

Have 7-Zip Extract to: and let it extract the file into its folder name (sp72370).

After that is done, go to the device manager and click to expand the Sound, Video and Game Controllers device category.

You should see an IDT HD audio device and a plain HD Audio device.

Click on the 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.

Restart the PC and now see if you get audio and video out of the HDMI port.

Hope this helps! Keep me posted for further assistance.

It didn't work. When I go to Device manager and click to expand the Sound, Video and Game Controllers device category I only see Realtek Audio drivers and not the IDT HD nor HD Audio device. What should I do?

I forgot to mention this but this is also an audio related problem when I connect my headphones to listen to music or play video, the video plays just fine but the Audio comes after 3-4 seconds and this is driving me nuts. I have encountered this only on headphones. Please HELP?

My system software and Drivers are up to date. But still I checked HP Support Assistant for driver updates and the Drivers are up to date.
But whenever I check for updates in HP Support Assistant I get these two updates (Listed below) but I have installed them and when I try to Install them they are overwriting the already installed files. So, they are the same Drivers. Any other solution?

I have contacted HP Support through WhatsApp and they seem to have no solution but suggested me to contact my TV support. But my TV works perfectly with all other computers and even Smartphones through HDMI. I don't know what else to do. Please HELP?

My  HDMI Sound problem is solved now, when I checked for windows update I got some driver updates and windows installed Intel Display Audio drivers. So, I had hopes and restarted my pc and connected my pc to my TV through HDMI and voila now the sound is coming from the TV.
