No HDMI sound on Pavilion dv7

I have a Pavilion dv7 notebook pc and when connecting the laptop to an lcd tv through my hdmi i get the sound through the speakers on the computer.

The Laptop is a dv7-4045ea

It has a ATI high Definition Audio Device and an IDT High definition Audio CODEC

When i go to sound options it shows it there and enabled and when going into properties it says the device is working properly, but still no sound through the tv. Please help.

Re: No HDMI sound on Pavilion dv7

Hi,

 

Try this to see if it helps.  Download the Graphics driver on the link below and save the installer to your Desktop.

 

ftp://ftp.hp.com/pub/softpaq/sp49501-50000/sp49517.exe

 

Next, in Device Manager, open Display Adapters, right click on the ATI graphics chip and select Properties.  Click the Driver tab and then select uninstall.  When done, do the same for the for the ATI High Definition Audio Codec found under Sound Video and Game Controllers - if it's not there just continue below.

 

Now return to the Desktop and install the Graphics driver.  When complete, reboot the PC and see if this has helped.  Check in Device Manager that both the ATI Graphics and the ATI Hi Definition Audio codec have reinstalled successfully and whether you now see the HDMI Audio option under playback devices ( found in Control Panel, Sound ) as shown as the top option on the screenshot below.

If it shows up correctly, try the HDMI connection and see if it now functions properly.

 

Best wishes,

Re: No HDMI sound on Pavilion dv7

HI, 

 

I have the Pavillon dv7 with beats on it. And when i was going to watch a movie it wouldnt allow the sound to come through my tv. I went to the sound option however it didnt have the hdmi sectional on there. And when i went to the beats audio it did but it wouldnt allow me to enable it. Do you know how to enable the sound on beats audio so that way it would come through the tv?
