Hello, Have a Dell Inspiron N7110 Laptop, was having no problem using a HDMI cable to send what was on my laptop display to my TV. Video and Sound were working fine. Now I just started getting the video signal but no sound to tv. The sound comes out of my laptop but not the tv. Haven't made any changes to my tv or laptop recently.....what could be the problem? Appreciate any help I can get....

You need to check that the audio processor on the Video card is enabled. To get sound from the HDMI port you need this option.

Right-click the volume control icon on the bottom taskbar and click on "Playback Devices" to open the pop-up window for sound options. In the "Playback" tab, select "Digital Output Device" or "HDMI" as the default device, click "Set Default" and click "OK" to save the changes. This method works with a straight HDMI-to-HDMI connection;

It works..very thanks u...internet is so so so usefyl
Thanks for the answer
May I add to this thread how I solved my 'no sound issues' even after having everything the way it should be and seeing the volume bar flashing as if the sound should be working!! It drove me crazy for 3 days...sometimes it worked sometimes it didn't and after scouring forums and the like to find a solution I finally found a clue. I have a Acer aspire laptop and a toshiba LCD TV and what Ive found out is.....

MOST IMPORTANTLY!! have the laptop speakers switched on for laptop only as normal WITH HDMI DISCONNECTED FROM LAPTOP BUT IN TV!!

switch TV off then back on and make sure its on the correct HDMI channel

THEN put HDMI into laptop....

THEN change the playback device to the HDMI connection to your tv

Im not very techy but with what ive read its something to do with a 'handshake' between your tv and laptop , basically if they are not introduced in the correct freakin manner they turn their noses up at each other and refuse to co-operate with each other like a pair of a** holes!

I sincerely hope my experience can help at least one person because it drove me nuts!!
It worked!!!!!!!!! Tried everything else and this finally worked after months. Was about to buy a sound bar....Thanks!

The real problem, is that HDMI is not a standard, so if you have a sony DVD and a Toshiba TV, they more than likley don't hold out the same "hand" for the handshake. When all the manufacturers decide on an actual standard, this type of "PICKY PLAY" will stop!
im havung same problem,i had sound through my hdmi when was watching film from my laptop to my big screen tv,but all of a sudden no sound now on my tv just on my laptop.i have not changed anything and if I put my hd lead into tv it does not go through and the sound still comes from laptop and it should be off on laptop and sound on tv,please help driving me mad.i can watch all sound ok its just when the hd lead is plugged into tv and laptop I does not go through for the sound just the picture please help.
I tried xpcman"s advice but I can not set my device (TV) as default. It reverts back to the PC's audio. Any other ideas?
