No sound on LCD tv with HDMI cable..Windows 7Solved/Closed

Question

Hello,  

I have a Dell Inspiron N7110 Laptop, was having no problem using an HDMI cable to send what was on my laptop display to my TV. Video and Sound were working fine. However, I am experiencing some issue with it, now. The TV is only receiving the video signal from the laptop. There is no sound. The sound comes out of my laptop but not from the TV. Haven't made any changes to my TV or laptop recently. 

What could be the the possible reason of this issue? Appreciate all the help!

Hi,

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.

Thanks!

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!!
