HP dv7-2277cl Pavilion Notebook Have no sound when using HDMI cable to TV sound works with Windows Media Player

You can connect via HDMI > HDMI if both have one, or VGA to VGA, VGA > HDMI all leads available on eBay. go to source and choose VGA option.

If your laptop has a HDMI output, and your TV has a HDMI input, then use a HDMI-to-HDMI cable, which carries both "audio" and "video" signals.

Otherwise, you need a cable from the "headphone" output from your PC into the "RCA" stereo-audio inputs into your TV.

If you have windows vista then connect the HDMI device to the notebook with the cable.
The click on start then type sound and select sound from the list.
In that please click right click SPDIF or something like that and click on set default.
The sound should work.
Start the audio file again.

That simple means its not compactable with windows 7. Anyway you can do a windows update on the net... That should work...

Are you using an HDMI cable to connect the Laptop to the samsung 540 tv If you are not then try using an HDMI cable, you will get the sound and a better picture

If you are not getting any audio through the laptop without the hdmi cable check that the volume control has not been turned down on either the laptop or on the windows volume control icon in the bottom right corner of your screen. Sometimes the easy solutions are the hardest to find.

When using an HDMI to DVI cable their is no audio that comes through that cable. Even if you use HDMI to HDMI most computers only have video output from HDMI. You will have to use a seperate audio cable for you to be able to get the sound to work. Depending on the output you have on your laptop you may have to resort to hooking up a pair of speakers to the headphone jack.

Hope this helps.

use fn+ f4 to toggle display between notebook and hdmi tv ;.....but make sure the cable is connected properly at both ends.

if it worked fine at some point then it should work fine now... i use hdmi to hdmi from my laptop to tv all the time dvi would only cause quality loss.

the first thing i would try would be to change your resolution on your laptop to a couple different settings. a lot of times, if its not set to one thats compatible with your tv, you won't see anything.

if that doesn't work, go to personalization and open the tab that says "connect an external display" and toy around with it. but yeah it doesn't sound like you have any hardware problems there.

hope this helps

try going to windows mobility center & click connect displays
