[Answer]No Audio from HDMI output

Question：I'm running Windows Vista SP1 on an HP Pavilion Laptop.  I would like to use an HDTV as an external monitor to play slideshows and other audi/visual media on the Laptop.

I have connected the Laptop and TV via their HDMI ports with an HDMI cable and I get a very good quality picture on the TV, but no audio.

I have used all the options on the TV to get audio and all seems okay.  I therefore suspect the problem is at the computer end.  Does anyone have any suggestions for how I might fix the problem?

Thanks

Answer 2： Hello Merlinca,

Thank you for posting to the Microsoft Answers Community Forum.

By default Vista does not route sound over the HDMI output.  To change this we need to change the settings in control panel. 

Note:  This will turn off sound from the speakers or normal audio output on the laptop.  To get that back you will have to reverse this process.

 - Click on the "Start" button
 - Click on "Control Panel"
 - With the Control Panel in "Control Panel Home" view please click on "Hardware and Sound"
 - Where it says "Sound" in green letters there are three options below that are in blue click on "Manage Audio Devices"
 - This will bring up a window labeled "Sound"
 - On the "Playback" tab there is listed the sound options available to you. One should read "Digital Output Device (HDMI)" Click on that.
 - There should now be a check mark on that option.
 - The Sound should then play through your HDMI hookups to the TV.

Plese post with results.

Thank you,

Answer 3： Hi Jonathan,

Thank you for the suggestion, but, unfortunately, when I follow your instructions and get as far as "Sound" I don't have "Digital Output Device (HDMI) as an option, so can't click on it.   The only options I have are "Speakers" and "SPDIF Interface"

Any other thoughts?
