No sound with HDMI connections

My new HD Island HDMI to HDMI cable arrived this morning
http://cgi.ebay.co.uk/ws/eBayISAPI.d...MEWN:IT&ih=006

I have connected my HP DV6820EA laptop
http://h10010.www1.hp.com/wwpc/uk/en...-81927552.html

to my Panasonic TX LXD52 LCD and the picture is great.

However, I have no sound. The sound volume increases on the laptop when I connect, but there is nothing from the LCD. What am I doing wrong?
Thanks

Re: No sound with HDMI connections

There's a good chance that's meant to happen. If the hdmi output is from the video card, chances are it won't carry sound anyway. BUT, if it's from the motherboard (with integrated graphics and sound) then it should. If that's the case, do you have the latest drivers installed for sound, graphics and motherboard?

I'm afraid that's quite incorrect - not only does hdmi carry video, it is also capable of carrying UNCOMPRESSED sound, of a very high quality.

Thumbs up Re: No sound with HDMI connections

I had a similar problem when hooking up my lads PS3 to his lcd tv..............picture ok but no sound.

Had to go to the sound menu settings on the PS3 and alter the source of the sound within the menu.......maybe you will have to do something similar?

HTH.

Yes HDMI can send video and sound. However from a PC it's a different matter. Usually in a PC you have seperate chips for video and sound. A video card for video and a sound card for audio. It's how it's always being done.

For years people have always connected the two seperate as well.

To get video and sound from a PC via HDMI someone needs to integrate a sound chip with a video card which is still rare.

Of course really the PC manufacturers should still be using DVI for video output but DVI to HDMI cables are not so common so maybe a HDMI socket was chosen as the cable would be easier to find.

To the original poster you may have a digital output or headphone output on your laptop. That can then be fed to an amp or the TV. Not ideal but using a laptop or a PC for viewing is still comparatively not that common outside of Powerpoint etc.

If it can be done If you right click the speaker symbol on the task bar it should let you select speakers or digital output if available.

With the player it depends on the software you use but if the sound output is set to digital then it generally follows that or 'right click and then select playback devices'. Either way try setting the sound output to digital if it can be done. May also be in control panel/sounds.

Re: No sound with HDMI connections

Thanks for your help guys. I called HP support and they told me to change my sounds/spdif to default. Did that and it worked after I rebooted. Im sooo pleased with the whole thing and I got a quality cable cheaper than other places that were selling something that seemed not as good.
