No audio, only video via HDMI

HP Recommended
Microsoft Windows 7 (64-bit)

Installed a new video card with HDMI port. Using my TV as a monitor,  I have video via HDMI but no audio. In the control panel, under sound, it shows that the HDMI is not plugged in, and therefore I cannot make it the default. Obviously it is plugged in if I have video via the HDMI cable. I've checked the drivers for the video card and they are up to date.

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.

  • Then download and install this free file utility.  The 2nd file on the page is for 64 bit.
  • 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.
