Connecting a laptop to the TV

http://h30434.www3.hp.com/t5/Notebook-Audio/No-sound-on-TV-when-connected-on-HDMI/td-p/1412875

A similar case above.

Post back your model number first.

> Sony's technical support says that I should set my settings on the Notebook so that the sound will come out on the TV's speakers.

Here's how to do it:

Control Panel
Sound
Playback
(or instead of the above three steps, right-click on the speaker icon in the system tray and then click Playback devices)
In the Playback tab, you'll see that Speakers/HP is set as the default
Click HDMI (or something similar — mine says AMD HDMI Output)
Click Set Default

Mine looks like this (being an HP laptop, too, yours is probably similar):


The last step is very important — clicking the Set Default button. When you want to go back to using the laptop's speakers, go through the same process but select Speakers/HP and set that as the default. Regards, Joe

Here is the model number of the HP Notebook : ZPM7HKZZ
THANK U

My HP notebooks are all EliteBooks, but the solution I posted above should work on any computer that has HDMI (or a DisplayPort, which is what my EliteBooks have — they work in the same way as HDMI ports, carrying both video and audio, as mentioned in my EE article, Dual External Monitors on the HP EliteBook 2540p). Regards, Joe

As mentioned in the comment above, do you see the following device in Playback audio device.

ATI HDMI Output

In no, install the driver below.

AMD installer

in response to Joe. I right clicked on the speaker.  n it showed the ATI  HDMI SPEAKER, N the speaker was the default.  I selected the ATI but I could not set this as the default.  And when I clicked back on the speakers. I could not make it as the default either.
This morning I was able to see the laptop on the TV with the HDMI still connevted.  But now I don't.  Not sure what button to hit on the remote of the TV.  thank u

> I right clicked on the speaker.

After doing that, select Playback devices. That will give you the Sound dialog box (as I showed above). Please post a screenshot of it.

> Not sure what button to hit on the remote of the TV.

It depends on what port on the TV that it's connected to. For example, the TV may have HDMI1, HDMI2, HDMI3, etc. (it may also have a VGA port, S-video port, and others). See which HDMI port you plugged the laptop into and select that one using the Input or Source button on your remote.

In response, I see the ATI and the speakers.  the speakers is checked but the set default is greyed out.  When I select the ATI it is still greyed out.  Attached is a snapshot of when I right clicked on the speaker on the task bar, then selected the playback device.  

With regards to the port on the TV it is connected to the hdmi port . and there is only such port,

OK, what that shows is that Windows isn't detecting the TV — that's why it says "Not plugged in". That's probably because either the TV is not turned on, or if it is, that the Input/Source is not set to HDMI. It could also be a bad cable or a bad connection, but those are less likely (although I've seen plenty of times when a cable is the culprit).

> With regards to the port on the TV it is connected to the hdmi port . and there is only such port,

Most TV remotes have a button that is marked "Input" or "Source". Some have specific buttons used to select the input/source, such as a button marked "Computer" or "HDMI" or "Component". You need to find the button on your remote that tells the TV to use the HDMI port as input.

in response to Joe, I got this sorted out of the picture not showing on the TV screen from the laptop.  But now there is no sound on the TV of the video that is played from the laptop.  And in the above discussions, I am unable to select the ATI ... as the default because it is greyed out. Regards

When the laptop screen is showing on the TV, open up the Sound dialog. Does it still say "Not plugged in"? If not, what does it say? Or just post a screenshot again.

In response to Joe, the screen shot is attached.   And it is the same when I did a right click on the speaker icon on the right task bar, andf then selecting "playback devices". thank u

No screenshot was attached. Also, check the audio settings on the TV. Most TVs have a Menu button where you can get to various settings. Look for an Audio section in the settings and see if you have to activate the HDMI port for audio. My TVs don't need it (they automatically output the audio coming from the HDMI cable when HDMI is the input/source), but your TV may require it.

Update: I downloaded your TV's manual from the Sony site. In case you don't have it, here's the link:
https://docs.sony.com/release/kdfe42-50a10.pdf

You've probably figured out that the remote's TV/VIDEO button (top row, second from the left) cycles through the TV's inputs, so hitting that key is what will get you to the HDMI input.

There's an audio troubleshooting section on page 92. Read the subsection on "Good picture, no sound", which has four entries. I'm sure you don't have MUTING on and also sure that the Speaker option is set to ON (otherwise, you wouldn't be getting sound from the TV's normal input, such as cable box or antenna). But the other two are possible culprits — the MTS option and the last one in the section, which is most likely to be the culprit because it is directly related to the HDMI input. Here's what it says (copied here under "Fair Use"):

When the HDMI IN input is in use, surround sound, such as AC-3 and DTS, cannot be input. Change the sound setting for the external input device to Linear PCM.

Give that a shot!

Also, the model number you provided for your HP notebook is probably wrong. A web search for "HP ZPM7HKZZ" gets zero matches. I'm pretty familiar with HP laptops/notebooks and never heard of a model anything like that. Please check again. Or better yet, run msinfo32 and look at the System Manufacturer and System Model fields. For example, mine says this (note that you may copy/paste from msinfo32):

System Manufacturer       Hewlett-Packard
System Model                    HP EliteBook 8460w

Another missing info is the exact HDMI cable you are using.

Please give details.

Also, post back what version of ATI Catalyst software you are using in your HP laptopm.

There should be a setting within ATI Catalyst software to enable audio over HDMI.

In response to Jackie, this is what I installed :
AMD installer

http://h20564.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_89582_2 

But I cannot HDMI speaker to show when I right click on the speaker.  It does not display when I do this.
Thus, I cannot get the sound from the TV only from the laptop.

The HDMI cable I use has both hdmi connections on both ends of the cable.  and I do not use any adapter but plug in directly to the respective ports.

Thank u and regards.

thank u for the solutions.

You're welcome. Happy to help. Regards, Joe
