Windows – No sound through DisplayPort

audiodisplayporthdmihp-elitebookwindows xp

I'm trying to connect my Elitebook 8440p laptop to my Samsung HDTV. The laptop does not have a HDMI connection, but it does have DisplayPort. I bought a C&E TOOGOO DisplayPort-to-HDMI adapter, and connected it with a 3 feet HDMI cable. The video shows up fine, but there is no audio. DisplayPort, HDMI, and the adapter all support audio.

I contacted HP tech support, who told me to update my sound drivers. I installed the driver and rebooted. Supposedly, I should see a "HD Audio" tab. No luck, even after installing the driver again and rebooting. HP closed the case. I'm using Windows XP Pro.

I travel a lot – here is what I do:

  • plug in HDMI
  • turn on TV to right input etc...
  • close the lid and let it go to sleep wait a few seconds
  • open the lid then quickly close it
  • wait for it to output video to the TV (you may need to reboot with lid closed)
  • then open the lid if you need to setup screens etc.. I found the intel software left in clone mode works great! My res is 1280x720

I use a display port to HDMI dongle but it should not matter.
