No Sound through amp when viewing content onlineon my 55L7200U only on TV Speakers

When ever I view video clips through the browser on my TV there is no sound that is sent back to my AMP. I can only get sound out of the built in speakers on the TV. Is this normal or should I be able to hear the sound through the sound system tha is hooked up to the TV. All other attchements, Blu Ray, Game console etc work through the amp just the TV does not.

Is it on specific content? Have you tried rebooting all devices and making sure they are up to date?

Same thing just happened to me too...
I did an update a couple of days ago: and it seemed to be working fine. Just did another update today: got a flashing light, sometimes a blank screen, and sometimes the itunes logo / USB symbol...

Then it is working! This is how it works:
Your built-in screen and you external screen are each show at sizes proportional to their pixel count. If this is not the correct arrangement, then drag the screens so that they correspond with their placement on your bench.
Then move the mouse off the edge of one screen, and it appears on the other. Next drag a window across to the other screen.

I just received my iPad2 today. When I turned it on it only showed a USB cable and the ITunes icon. What does this mean?

The first thing that needs to be done with a new iPad is to activate it by connecting it to a computer running iTunes (version 10.2 +).

Pavilion g6-1b70us. Picture but no sound from tv when using HDMI. Previously worked no problem.

I have a pavilion g6-1b70us that I am trying to hook up to my tv with an hdmi cable. I get a picture, but no sound. This previously worked with no problem. When I pull up my sound playback settings the only options are speakers and headphones. When I pull up my devices, the Samsung tv is there, but is described as a "generic monitor" (thought that was weird). I have uninstalled and reinstalled my intel graphics driver and IDC audio driver but still no sound through TV. Also, I will mention that in under control panel>devices and sounds there is a link to SRS Premium Sound. As you can see in the picture below, the Samsung device shows up, but it is grayed out and cannot be selected. Can someone please help?
This question was solved.
View Solution.

Well in case anyone is interested I fixed the issue (only took me 12 hours to figure out, lol). Apparently even though the Samsung tv was not appearing in the sound playback options, you can still right click in the blank area and an enable/disable option will appear.

Sound drops off when using hdmi outport to connect computer to an AV reciever

Satellite M640,I5 2410 processor, windows 7HP. After about three minutes the sound drops off when connected to the av reciever through the hdmi outport. If I touch the trackpad the computer reconnects for another three minutes and then disconnects. If I touch the the trackpad about every two minutes the computer stays connected indefinetly. This problem does not occur if I use the computer to play an audio CD. Any fix suggestions.

Hi peter,
try to repair your permission by open application folder > utilities > disk utility > repair permission.
It should fixed the unexpectedly quit for several applications.
And try to get latest info from Griffin sites, maybe this one will help too:

No sound from the TV when using HDMI cable, No sound from the TV when using HDMI cable

I recently purchased HDMI cable and adaptor, so that I can play downloads from my Macbook Air on my TV. There is only sound from the Macbook, not the TV - Do I need as separate cable for sound?

I've got the same issue: when I connect my Macbook Air (2011) to TV via HDMI cable there's no sound through the TV system, only from the Macbook Air. I used to use my older Macbook Pro with the same HDMI adapter and it worked just fine, but not with the Macbook Air it doesn't.
My software is up to date. I tried to select the TV as an output option in sound preferences, but it doesn't yield any results.
Rebooding multiple times doesn't help either.
Any suggestions on how to tackle this problem?
Thanks in advance.

My Macbook Pro wont play sound through Mini DisplayPort to HDMI adapter on toshiba television anymore. The sound plays through sony or samsung television, but not toshiba television.

I have a Macbook Pro early 2011 running on mountain lion version 10.8.2. A while back, i purchased a mini display port thru HDMI port so i could watch dvds on my toshiba television. it all worked great for a while, then the sound just stopped working. At first, I thought the mini display port connector must have broke, until I plugged it into a sony television and it worked. I also tried using it through a samsung television and it worked just fine. Why does it not work through the toshiba television anymore? The picture works fine, but the sound does not come thru the television anymore. My mac is set to play sound thru the HDMI port and it doesnt. When i switch it to built in internal speakers, the sound comes thru my mac, but when i switch it, no sound comes out. Any help would be greatly appriciated. Thank you!

I am still waiting to receive a response from them, but i dont think they'll be much help. the television still works fine and all of the ports on the back, including both HDMI ports, work perfectly.

No sound from TV when using HDMI from HP Envy Ultrabook4 despite downloading drivers

Problem: When using an HDMI cord from my HP Envy Touchsmart Ultrabook 4 (4-1105dx)to connect to my TV to view movies, the video appears on my TV screen, but there is NO sound from the TV. Instead the sound comes from my lap top.
Troubleshooting: I have looked under Sounds in the Control Panel, but the only choice listed is Speakers & Headphones IDT High Definition (which is the default) and does not allow sound from the TV when using the HDMI. I have also tried to download Driver and Audio Graphics, but wasn't sure which one & the ones which were downloaded have not solved the problem.
Can you assist me? Which is the correct Audio/Graphic Driver to download? Or is there another possible reason why I cannot hear sound from my TV when using the HDMI to connect to my lap top?

Hi,
Please try this first to enable Speakers in Playback devices as follows:
1. Right click speaker icon (bottom right hand corner)
2. Select Playback devices
3. Right click HDMI sound
4. Enable it
5. Click Apply/Ok
Regards.

No sound on TV when using HDMI cable from MAC

Hi
Anyone any ideas why I cant get any sound on the TV when I plug the HDMI cable in - It only comes thru on my MBP.
Also, I have to scroll the mouse off screen and grag any windows off screen in order for them to display on the TV .... It must be smething to do with resolution or something...But I cant work it out
Any help gratfully received
Thanks
Emma

To get sound you will have to tap into the audio output port. This will require a 'Y' connector with a compatible plug that fits the port and splitting into the two audio channels with RCA connectors. The image shows a possible type you can use, but you would still need two male/male RCA connector extensions to your TV. A little search on the Internet should enable you to identify the most practical way of connecting audio.
The ideal set up is to use the extension shown with a Y connector with male out put connectors.
Ciao.
