Hi:

In order to try and help you, I would need to know the full model number of your notebook and what operating system you are running.

[TheDarkendStar]

Sure Here it is

HP ENVY 17-j181nr Notebook PC (ENERGY STAR)

Model #:E8A07UA

The operating system is windows 10

OK...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.

I hae hp 350g1 laptop when connect hdmi cable there is no sound on tv

I have a hp elitebook 8440p  sj990up windows 7 professional 64 bit  and it is no longer sending sound through the hdmi to tv connection. When I first used the cord a week ago it worked but now it isn't.  i've tried uninstalling and reinstalling the nvidia hdmi drivers from the hp sight as well as the nvidia sight. I've tried updating the bios as well.  For whatever reason my tv doesn't even show in my playback devices even though it once did.  I've tried looking under disable and disconnected devices as well.  I was wondering if you might be able to lead me in the right direction as to how to resolve this problem

I just followed those instructions exactly, but when I click to expand the Sound, Video and Game Controllers category, I don't see an IDT HD audio device. 

What do I do??
