No sound through HDMI cable

I have an HP Phenom DV7-4178NR. Audio works fine on the PC. Audio also works fine with the HDMI cable through other devices. I know it's a problem with the laptop and not the cable.
Under device manager, display adaptors it says: AMD M880G with ATI Mobility Radeon HD 425.
Under sound video and game controlers it lists:
ATI High definition audio device
Bluetooth hands-free audio
hp webcam splitter
IDT high definition audio CODEC
Also I'm using window's 7.
Any help please?

no ideas anyone?..

No sound through HDMI cable after upgrading to Lion

After upgrading to lion I can not get any sound through my hdmi cable connected to the TV. It did work before. There is no optional source to choose under "Sound" - only internal speakers. How can that be? Any suggestions what to do?

You arent the only one.
I guess that is a thunderbolt bug and needs to be fixed by apple.

Sound through hdmi to my tv works but not when watching video online like 4OD

the sound through hdmi to my tv works with music and videos I have downloaded, but not when watching video online like 4OD and youtube.
How can I get it to work?

Ok so I happened to figure it out while on the phone to apple support. Even though the guy was very nice, I think I knew more than him! He was explaining very basic resolution principles I played about. I had the second option in displays resolution. All I did was unplug the HDMI cable, click on 'best for display' then plugged the HDMI in and my resolution on the normal monitor changed to the normal blue, then went black momentarily and then changed to a strange resolution but another window appeared that said SONY BRAVIA HDMI at the top! Hey presto! Don't know why it didn't do it yesterday - I probably left the HDMI cable in or something! Oh well. Problem solved!

No sound through HDMI on Satellite Pro A200

Hey everybody,
I have Win XP installed on my Satellite Pro A200.
When I plug in the hdmi cable the video goes through to the tv but the sound still plays on laptop speakers.
I have tried changing the output of the sound to all the possible options but it just doesn't seem to work.
Any ideas?

Tnx, I find that under xp it was slightly different:
Go to control panel
select "sounds and audio devices"
select "audio" tab
set the default playback device to be "ati hd audio rear output"
then restart the machine while plugged into the tv
annnnnnd voila :)
tnx dudes

No sound through hdmi - macbook pro

I can connect my tv to my macbook pro through a HDMI cable and the picture shows up perfectly. However, the sound goes through my laptop speakers and not through the tv. When I go into Preferences --> sound --> output, there is not option to select for the hdmi, just the internal speakers. How can I get the sound to go through the tv instead?

no, it is not, but after searching these boards even more i discovered this gem, and now all is good, except that u have to change the audio each time......i think......so i mite get an audio cable to make it easier for my hon to hook up........here is the gem

Re: No sound over Mini DisplayPort to HDMI Adapter Sep 12, 2011 1:09 AM (in response to yvonnelouise1)
DisplayPort to HDMI Sound is actually set up by using the MIDI setup utility found in :
Applications > Utilities > Audio MIDI Setup.
If you purchased an iWires cable direct from Apple the instructions are in the printed booklet that comes in the packaging. Most people don't read this as it's normally the case that when you plug a cable in to anything it just works (VCR, TiVo, Xbox, video camera etc). In this instance Apple are failing to live up to their catch-phrase as final setup is NOT intuitive; "it just DOESN'T work".
The booklet instructions basically say do the following,
Video
System Preferences > Displays. There are 3 tabs in the window; Displays, Arrangement and Color. Be sure you are on the Displays tab. Bottom left of the window tick "Show displays in menu bar" and then bottom right click "Detect Displays".
Now click on the tab named Arrangement. Bottom left of the window tick "Mirror Displays".
You should now only see 2 tabs, Display and Color. Be sure you are on the Displays tab. Select the desired resolution for your TV (probably 1080i). leave all other settings at their default values.
Sound
System Preferences > Sound. There are 3 tabs in the window; Sound Effects, Output and Input. Be sure you are on the Sound Effects tab. Middle of the window select your TV where it says "Play sound effects through:".
Select the middle tab named Output.
Select your TV from the drop-down list next to HDMI, below where it says "Select a device for sound output".
Using either Finder or Launchpad go to Applications > Utilities > Audio MIDI Setup.
On the left-hand side of the window you should now see HDMI. In the middle of the window, on the Output tab, where it says "Source:" select your TV from the drop-down list.
This last action below is NOT described in the iWires notes but was required in my case, it may also be required in yours. If you CANNOT see a speaker icon next to HDMI in the list on the left, do the following:
Bottom left of the window select the wheel icon with the down-pointing triangle. Make sure that sound output is selected and that you can now see a speaker icon next to HDMI in the list of devices.
If you still cannot hear sound, log out of your account and then log back in.
You will now have sound coming out of your TV from your computer
You may have to do some or all of the above to get sound out of your TV from your computer using the DisplayPort to HDMI cable. On my Aug 2011 MacbookPro I had to do ALL of the above. If you take your laptop to a different TV you will have to do it all again so be warned.
Hope this helps. "

No Sound through HDMI - Mac Mini

Hello Forum, New user to this forum, I have a problem, I have bought Mac Mini ( August,2010) for home use and recently bought LG -32LD450 - 32". I have connected my TV directly to Mac Mini using a 1.3X HDMI cable. I have video/ display - however no sound. All i can hear is sound from the Mac Mini's internal speaker. I tried to change the setting through - System preference/sound/output. It displays - LG / HDMI - however i cannot select, the setting is active with internal speakers only. Please advise how i can obtain audio from the TV.
I forgot to mention the message seen in System Preference/Sound/Output - LG TV HDMI - Settings for the Selected Device : The Selected Device has no output controls.
In addition to the above, i have tried to check the output controls through Utilities/Audio Midi Setup. Here too i am not in a position to alter HDMI Settings.
Help in this regards is highly appreciated...thanks
Please help

Krusdublin: I am experiencing similar issues with no real solution yet:
I have a Mac Mini 2010 connected to a Sony Bravia HD TV via an HDMI cable
sound output via TV speakers was not working when I first connected the two (about 4 mos ago)
couldn't figure it out- and just used an headphone cable to connect the mac mini to a stereo
somewhere between then and a month ago I disconnected all incl. power, and reconnected as I had to re-setup my tv (all reconnected in the same outlets via HDMI) (also got rid of the stereo at this point)
then about a month ago I was back in the Sound preferences and found that I was able to get audio output via the TV speakers.
about a week or so ago I disconnected all incl. power, and reconnected as I had to re-setup my tv (all reconnected in the same outlets via HDMI)
however, about 3 days ago, sound output via TV was no longer an option
when I say it is not an option, I have two lines under name and types as follows:
"Internal Speakers" > "Built-In Output"
"SONY TV" > "HDMI"
when I switch from internal speakers to HDMI, I notice that the sound volume bar at the bottom of the screen goes faint, and I can't adjust the volume using the sound keys on my keyboard (bluetooth)
the speaker icon in the top right of the screen is also greyed-out and not changeable...
I notice that when I switch input on my TV aerial to the MacMini (HDMI 1) I get a little yellow triangle with exclamation mark in it, and the text: "AUDIO only" at the bottom right of the tv screen. (In not sure if I had this before or not - dont completely remember seeing it, but vaguely do...)
I've also updated my macmini whenever an update is released (within a few days)...
I've spoken with an Apple tech over the phone and went through a number of reboot (while holding down certain keys, etc.) to no avail. She then recommended that I go into the Apple store and have the mini checked out....
At the apple store, the apple tech took the machine to the back, out of sight, and returned about 20 mins later to say that it was working fine. I asked to have it hooked up to one on display - so I could see for myself. We hooked it up to an HDTV via HDMI and booted up. Went to System Preferences > Sound and selected: "Panasonic TV" as the output device. I still could not adjust the volume bar (it went greyed out) - but I could crank up the tv volume directly and get sound. Great! Sort of... While now I could get sound - it was not the same as before where I could control the sound through the mac - only directly through the TV. The Apple guy said that he didn't know what I was talking about - and said that they way the machine was now working was the proper way. He unhooked my mac mini, and gave it to me, and walked away.
Frustrated, I walked down to the Sony Store to try out the mac mini there. Same result as in the Apple store. I could control sound directly via the TV, but not through the mac mini controls.
Took the mac mini home, reconnected everything and now get sound through the TV - but I cant control it with the mac mini on-screen controls, nor the volume buttons on the mac blue tooth keyboard.
Today, I was watching a movie via itunes, hit pause, and went to do something for a few minutes. When I returned, the TV indicated 'no signal' via the HDMI (I assume because the mini went to sleep.) Tried to wake the mini - but couldn't. Had to resort to pressing the button at the back. When the mini came back, I had no sound at all coming through the TV speakers, even though the sound preferences settings were still the same. I had to resort to shutting down the mac mini, and then unplugging the power on the mini for a few minutes. Powering back up, sound was again able to comefromt eh mac through the TV speakers - but still could not control sound using the mac mini controls.......
Thats where Im at so far....
Aarrgh.
THOUGHTS?
Thanks in advance,
MAJM

HT1338 no sound through hdmi after sleep mode

I have no sound through the hdmi cable after mac mini wakes up after sleep mode but I do have sound when I resart my mac although Im unable to ajust the volume and the sound icon at the top bar is greyed out..system preferences says the selected device has no output controls for this device and the slider bar it also greyed out..

If you don't already have a current backup, back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

Surround sound through HDMI?

All the new Mac models released in the past 12 months are supposed to be able to output multichannel audio through an HDMI connector. I have recently purchased a new MiniMac with an HDMI connector and was really looking forward to playing multichannel sound through one of my two Onkyo home theatre amplifiers. Unfortunately, it doesn't work. For one of the amplifiers (Onkyo TR SX576), the Audio Midi Setup application found an 8-channel device and named it TR SX576, but I was unable to get any sound played through the system.
For the other one, a slightly older model (TR SX506), which has a Samsung LCD attached, the Audio Midi Setup just reports HMDI (0in/2out) with "SAMSUNG" as the name. I can't output via the amplifier... it seems to just pass the audio though.
So, here's a simple question. Is there anyone who has succeeding in outputting multichannel sound via an HDMI cable to a home theatre amplifier? If so, what Mac, what amplifier? What is missing to allow Macs to talk with all home theatre amps via HDMI??

Hi levelg
levelg wrote:
Great. The only problem is that when I define 8channel sound, the amplifier doesn't do any surround sound processing, and so virtually everything that I can play on the Mac only comes out of two speakers . To get surround sound effects (Pro Dolby etc), I have to revert to 2ch-24bit and allow the amp to do the surround effects.
This reminds me of another question. Why on earth can't the Mac's Audio allow you to add surround sound processing directly?
I think the answer to your question is that using the HDMI would require the Mac to have an AC3 codec, which would take up to 6 channels of audio and then compress them into a Pro Dolby data stream which your amp could then decode. (This is actually the reverse of the "AC3 Codecs" that you might find available for download on the web). I believe that this software component would require a separate licence fee, and also might not work sufficiently fast in real time to avoid lip sync problems. It could also result in severe quality degradation in certain channels due to the amount of compression. You can't squeeze 6 channels into 2 and then back again without losing some quality along the way.
The result of this is that HDMI and TOSLINK connections from the Mac can play prerecorded surround sound from a DVD, etc, since this can be passed to the external decoder unchanged, but can't play audio generated on the fly by applications. (At least, that's what I've found - someone else might know differently)
I know from personal experience that it IS possible to buy an external USB 5.1 sound card to connect to a 5.1 audio system, and this will enable on the fly audio generation from applications. The same setup will also play surround sound DVDs, provided you use the alternative VLC DVD player.
All in all, the whole area of surround sound on Macs is extremely confusing! I'm worried that many users either buy the wrong equipment, or they buy the right equipment but then can't figure out the correct way to configure it. Such users inevitably end up frustrated and disappointed.

No audio through HDMI cable when listening to audio tracks but ok with vids

Please Help!!
Ok I hooked up my HP to my Samsung 1080p hdtv through an HDMI cable. My computer displays fine on the TV, the visualizer in ITunes shows just fine, but the audio only comes out of the speakers on my laptop when playing a regular music track. When it plays one of the bonus music videos on the same album, audio and video both play. When I play the songs in any other interface, ie windows media player and HP quick play, audio tracks play fine through HDMI. So this has to be something with ITunes. Anyone know what the problem is?
Thanks!

Wouldn't you know it, just figured it out. You have to make sure that itunes is not loaded before hooking up the HDMI cable. So,
turn off itunes,
hook up the HDMI cable,
(go to sound [control panel] and make sure that HDMI has the checkmark next to it),
load itunes,
enjoy.

On my laptop, I have to add "options snd-hda-intel probe_mask=0xffff,0xff2" to a modprobe.d conf file. You can try that.
sudo su
echo "options snd-hda-intel probe_mask=0xffff,0xff2" >> /etc/modprobe.d/sound.conf
exit
After that, restart and hopefully it will work.

No sound through HDMI

I just bought myself a new Mini DisplayPort to HDMI, because the old one was broken. So I have used a HDMI cable before, and everything went fine.
But this one isn't working and I have tried everything. I've looked at my audio settings, and everything seems fine. I took some printscreens:
What can I do more?
Thanks in advance

Hello
Uninstall the sound drivers restart your computer and the computer will install the drivers automatically.
If that does not work:
01. Go to Sound Properties
02. Plug the HDMI cable in
03. Make the HDMI output the default one.

Hi, Mike:
See if installing the ATI HDMI audio driver directly from Realtek gets the HD audio device to show up in the sound control panel.
Accept the agreement, download and install the
