Sound through HDMI when playing a Keynote Presentation

When I link my 4th gen iPad to a TV with Apple's HDMI adapter I get really good sound and vision through the TV when looking at iTunes videos or Youtube. But when I try to play embedded video in a Keynote presentation sound is only available from the iPad's headphone socket. Any solutions?

Sorted, thanks to the iWork Team at Apple. I had the mute button on.
To be fair to me, I use the side button to lock/unlock rotation and it didn't affect those other apps. But still, highly embarassing.

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!

Thinkpad S540 - no sound through hdmi

Hi,
Just installed win 8.1 x64 on my S540, updated all drivers from lenovo support site and all went smooth, but I cant get the sound to work through hdmi when I cconnect my s540 to my tv, internal speakers keep playing and I cant even select hdmi output in control panel -> sound.
here are some pictures, they are in swedish but you might know what it's suppose to say in english:
here you can see what it looks like when my hdmi is connected to laptop from tv, does not even say connected

And here you can see that it is not even possible to make hdmi out put "default" playback device as one should be able to do

Still, laptop knows it is connected to my sharp tv via hdmi as intel control panel says it:

Deinterlaced QT HDV clips do not remain deinterlaced when played in Keynote

Anyone knows why?
Deinterlaced QT HDV clips (deinterlaced through the de-interlace box in the video-track properties) do not remain deinterlaced when played in Keynote 2.
BTW I have found deinterlacing QT HDV clips in FCP not to be fully satisfactory.
Any better solution for deinterlacing finished HDV clips (1080i50) available?

#25 HDV external Monitor Viewing
Shane's Stock Answer #25 - HDV external Monitor Viewing
To view HDV on an external monitor you are going to need to purchase a capture card, like the ones Decklink or AJA offer. They will both play out HDV in real time. The catch is that you cannot view this on a regular TV or NTSC monitor. Since this is HD, an HD monitor will be needed.
HDV cannot be played out of FCP via Firewire because it's Long GOP structure is too taxing on your processors to spare the system resources needed to drive an external monitor.
The best option you have is the Matrox MXO...$1000.

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 alternative solution

If you are not able to get sound through your TV through HDMI and have tried all the System Preferences/Audio MIDI steps detailed on here in other threads but nothing works, try just shutting down all running apps.
I had to Force Quit Spotify, Viber, Skype - when I shut down iTunes, the sound from Firefox started coming through the TV. I have since been able to reopen Spotify and play it through the TV too.
I'm not sure why these apps would interfere with the HDMI sound transmission, perhaps more technically inclined people can answer this but it turned out to be a straightforward solution that I didn't find on here (although maybe I just didn't look hard enough!).

Is it an occasional problem or is it that you have never had the hdmi audio output working with windows 7 Ultimate? If it has never worked, is hdmi even listed under playback devices when you right-click the speaker icon in the notification area and click playback devices?

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 sound through HDMI in Radeon 6870

Hello People from Arch Community
I have a small problem getting sound out of the HDMI of my video card.
When I do
lspci | grep AMD
I get:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Barts XT [ATI Radeon HD 6800 Series]
01:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Barts HDMI Audio [Radeon HD 6800 Series]
So the kernel finds the device. But when I do
aplay -l
I get:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC887 Analog [ALC887 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC887 Digital [ALC887 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
I noticed that the HDMI out was listed as Audio Generic, when it should be identified as HDA ATI HDMI. Whenever I choose the HDMI output through alsamixer I only get a s/pdif and I cannot modify anything. I remember that some months before when I installed Arch for the first time sound through the HDMI was working and the audio device was correctly identified. Could it be a new module or kernel path that broke the audio?
I tried using the radeon.sound=1 flag but I still could not get sound out of the HDMI. Even worst, when I use the radeon.sound=1 parameter, my screen display a 5 pixel width purple line at the left border of the screen and the rest of the screen gets squeezed. It is not too bad but still makes text look blurry.
Could someone help me please?
Extra info: it is not hardware related, sound works fine in windows
I am not a total beginner, I know my way in the CLI but still I lack a lot of knowledge.
Another tip, around the same time, my framebuffer decoration and splash(fbcondecor, fbsplah) stopped working, I don't know if it is related.

You may find this article >Here< to be of interest. I don't know much about Radeon audio but for your 6870 that may seem to be of relevance.
Are you using the open-source driver or the proprietary with an older X.org? With the above article, the open-source audio seems to be slated for kernel 3.5.

No sound through hdmi satellite a505-s6960

I have been having a problem with getting sound through my hdmi port. to a panasonic viera television 42" though it does play on my friends 52" panasonic viera.
it has worked on my television before but its not working lately for some reason. any tips would be great it doesnt play through the digital audio it usually played through panasonic viera in the sound playback options.

Hi man. I tried a lot of ways, I chaged controls, update software anda a lot of things, but here you have to do the next things. Conect HDMI port in both elements: TV an laptop. Try changing the conection between the elements with the bottons "Fn" + "F5" in this case F5 is the funcion to change between LCD, LCD+HDMI, Monitor, etc. Do it three or six times to get the sound in your LCD. I hope this idea help you.

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

SB Audigy 2 ZS Platinum "colors" the sound of music when played back. How to change th

I recently purchased a Line 6 POD X3 for recording guitar tracks, and when connected using USB it can function as my computer's sound device. Now here is what I observed:
In all cases described below, the "reference" case is that of the guitar played through the POD X3 with headphones connected directly to the POD (no computer sound device involved).
) When I record guitar tracks using either the POD X3 or the SB Audigy 2 as the computer's recording device, and then play the recorded tracks back using the POD as the computer's playback device (headphones plugged into the POD), the sound is exactly the same as the reference case.
2) When I record guitar tracks using either the POD X3 or the SB Audigy 2 as the computer's recording device, and then play the recorded tracks back using the SB Audigy 2 as the computer's playback device (headphones plugged into the SB Audigy 2), the sound is MUCH different than the reference case.
To put it simply, the Sound Blaster card is "coloring" the tone of the recorded guitar (regardless of recording device) during playback. I realize that the Sound Blaster drivers are probably designed to "enhance" sound for gaming and such, but the way it shapes the sound of recorded music during playback is extremely undesireable for home recording projects.
Here is another clue that leads me to believe that the Sound Blaster drivers are responsible for this tone shaping: If I am playing my guitar through the SB Audigy 2 and monitoring the sound through computer speakers or headphones (hooked up to the SB Audigy, of course) WHILE Windows is booting up, I can hear a very distinct change in the sound when the SB Audigy 2 drivers are loaded. It seems to me that when Windows is booting up, the Audigy 2 card allows transparent playthrough before the drivers are loaded, but the drivers then take over and shape the sound.
So, if you've understood my observations, my question is how can I avoid any sort of tone shaping during playback by the SB Audigy 2 drivers? I want completely transparent playback such that what I hear during playback is exactly what it sounds like going in, i.e. the reference case described above.

Just for kicks, I decided to install this card on a Dell that I happen to have around.. the specs are above and beyond the configuration of my regular computer (whose specs are above and beyond the specs listed for the Audigy 2 ZS Platinum).. and I am unhappy to report that the same freezing problems occur. I am still unable to use any web update features for ANY of my software, and I am still unable to record in 24 bit audio.

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.

Satellite U400-15E - Upgraded to Windows 7 32-bit now NO sound through HDMI

I upgraded from vista to windows 7 32-bit, now i have no HDMI device shown under playback devices, i have installed new windows 7 drivers but still no luck. Under device manager/sound a HDMI device is shown as enabled and when connected to an external TV video is shown but no HDMI sound. please can someone help......

I have found out the solution to get HDMI sound to the TV
1. Right click volume icon on taskbar
2. Select playback devices
3. Right Click on SPDIF Interface and select Default Communications Device.
4. Connect HDMI from TV to Laptop
5. HDMI Device should be selected automatically.
When HDMI is disconnected the HDMI device is shown as disabled in playback devices whereas previously this device wasn''t shown at all.
