I have an HP dv9000 and a brand new Phillips TV and when I try to hook then together, the tv displays the picture beautifully but there is no sound on the tv, Just the laptop speakers. PLEASE HELP!!
Had same problem with Windows 7 and Toshiba laptop and Toshiba TV, video through HDMI cable but sound out of laptop. Was working fine for over a year (both sound and audio out of TV through HDMI) then one day sound just stopped.
Going to - Start Menu - Control Panel - Sound - Playback tab.
Your TV should be one of the playback devices listed. If not, right click inside the device list box and select 'Show disabled devices'.
Now that TV is listed as a playback device, right click on it and select enable. Then right click again and select 'set as default device'.
Green check mark should now appear on TV icon and sound should now come from TV with video.
I had the exact same problem, and none of the solutions worked! I'm running from my laptop to TV via HDMI, and the sound usually projects through the tv once I plug the cable in. The solution I found was to open the Device Manager, and down at the bottom of the list, under system devices, I found that the High Definition Audio Controller was disabled, mysteriously and on its own! I enabled it, and VOILA, the audio was immediately transferred to my TV! I have an external speaker system hooked up to my TV's audio output, so now my laptop is working on a bigger HD screen w/premium stereo sound!
Start Menu - Control Panel - Device Manager - System Devices - High Definition Audio Controller - right click - properties - enable
"Control panel, hardware and sound>sound>manage audio devices>set default> digital audio device. Change back to spearkers and headphones when done."

For those of you who are still having a bit of trouble getting sound through your TV using an HDMI cable, and have following these steps and verified that the TV is being seen as a proper display device, make sure that the volume for the TV display device is also turned up.
When you are in "Manage Audio Devices" (follow description quoted above to get there), right-click the symbol for your TV and click "Test." Then watch the bar to the right of the description to see if it starts moving. If it does, and you still can't hear anything, that means that the sound is working properly, but for some reason the volume is turned down, or off. Right-click the description for your TV, then click "Properties," then click on the tab that says "Levels." There should be a volume slider here, and chances are it is set to 0. Turn it to the volume setting you want, then click "Apply." Now go back and try testing the sound again from the previous page. You should hear some sort of a "chiming" sound. That means that you have done it right.
For some reason, I had my laptop volume turned up as high as it would go, but nothing was coming through the TV. When I turned that slider all the way up, it started working again. However, now my volume hotkeys on my laptop actually effect it, where as it didn't before. I have no idea why, but this solved it.
I was trying to figure this out for ages. I have a HP laptop and have bought a HDMI cabel, connected to TV and no sound.... you need to go to control pannel and sound. Click on the option underneath SPDIF Interface( well thats what mine says!) and set as default. I did this and found it still wouldnt work, the reason was I was playing the film through windows media player- my TV didnt support this fromat, so I then played it through VLC media player and I had sound throught the TV, was simple!! hope this helps.
