Dolby digital in itunes over hdmi for 7770

I just bought a amd sapphire 7770 and now itunes won't output dolby digital over hdmi but other programs will. I am using the latest drivers and software, how do I fix this?

Hi I am having the same problem but I can't get any sound from the surround on sky. I have tried all sorts of combinations including what you have put on this forum. Is there only certain channels on sky that now produce the dolby digital. On my prev tv I had surround sound with all of the channels. This new tv is a 3D smart tv. Thanks any help would be much appreciated.

How to enable dolby digital in itunes

Hello, what steps are needed to enable dolby digital to work in ITunes? Thanks.

Set up iTunes and your DVD Player for digital surround sound - Apple Support

I would like to connect my Apple TV to my receiver using an HDMI cable and pass thru dolby digital. I do not have optical inputs on my receiver.

I want to connect my Apple TV to my receiver using an HDMI cable. This should allow me to pass thru high definition video and simultaneously decode Dolby Digital material with an HDMI connection from my receiver to my TV without the use of an optical cable (my receiver does not have an optical input). I am unable to decode 5.1 material and don't understand why this is not working. In the audio setting I have Dolby Digital output turned on.

Welcome to the Apple Community.
Are you sure the content you are playing has Dolby Digital.

G62-a50sf : (only) audio out over HDMI?

We have a G62-a50sf notebook at my gf's place that we'd like to use as the source for a (somewhat) audiophile audio set-up. One possibility to get better-than-headphone-output into a good receiver AND avoid using a separate DAC would be to feed the digital audio output over HDMI to the receiver.
The question I'm hoping to get an answer to is: will this be possible while retaining video output on the laptop's own screen?
thanks in advance,
René

Sorry, but your Mac doesn't send sound over HDMI, only mid-2010 and later MBP's send sound (and even then some require different adapters). Yours is a 2009 MBP, so only video will go over the HDMI cable. You will need to run audio from the audio out to your TV or digital audio out from your optical audio out to your receiver.

Z68MA-ED55 (B3) - Realtek HD Audio over HDMI

Does anyone know if the motherboard Z68MA-ED55 (B3) is able to get HD Audio out from the HDMI connection?
When I installed the Realtek HD codec I only see listed two digital outs: optical and atapi. (which I don't know what atapi is for)
I think my motherboard need bios updates as mine is in version A1, and the latest A4 seems to fix some audio tables (which I don't know what it means neither..
Anyone has HD audio over HDMI for this board or advice about what to try?
thanks
Update:
Seems my board should support HDMI HD Audio out..

Any luck getting HD audio to work over HDMI?

Sound over HDMI works halfway.[SOLVED]

//After looking around, HDMI only sends the signals to turn down the HDMI connected device. I guess it's as good as it gets...//

720p over HDMI - black bar issues

Hi all.
I've got a 1st gen V-box, which worked great until about 9 months ago. I had been happily using 720p over HDMI for about a year. However, I suspect a software "update" around this time caused problems, as the 720p and 1080i settings are now incredibly unreliable.
Specifically, when I set the box to show HD resolutions, there are usually black bars down the left and right of the screen, cutting off those sides of the picture. Sometimes the picture displays properly, but this is usually only temporary - after a day or two of thinking everything's sorted, the dreaded black bars reappear when starting the box up for the first time that day. Rebooting doesn't seem to help. The bars even overlay the menus, so it seems to be affecting everything not just live tv. The full picture is shown when I use standard def over HDMI however.
Has anyone else experienced this and if so any ideas how to fix?

Hello
On most platforms, I've experienced black bars at the sides, noteably lower bandwidth channels such as kids or shopping often display what you describe when using any HDMI setting in my experience.
Thre is the ability to hit the shortcuts button on the bottom right of the remote which allows you to scroll through to then stretch the image if you wish- but It doesn't always work, I'll stress again this also happens on my FREESAT box, so I don't think it's an issue generic to Vision.
Couple of questions though,
1: Is it a Toshiba tv? (some firmware upgrades to these sets have caused numerous issues and lip synching problems.
2: have you tried a different HDMI cable? (apologies if that's blatantly obvious!)
I've not tested V.1.5 black box yet to see how this issue is there (note I don't call it a V2 box- as it's **bleep**).
Hopefully, if the rumours are true the development team will scrutinise the forums, realise these issues do indeed exist and can work towards a solution in the Freeview HD offering of whatever comes out next:

Netflix titles not in Dolby Digital

I use a digital optical cable to connect my Apple TV to my Sony receiver because my TV does not support Dolby Digital pass-through via HDMI. I've discovered that Netflix titles won't play in Dolby Digital. I can verify this because my Sony's display shows LPCM.
I can get DD output from the same Netflix titles using my TV's Netfix app or my Sony receiver's Netflix app and I can also get DD output from purchased movies and TV shows on my Apple TV. The receiver displays "Dolby Digital".
Is it possible that the Apple TV isn't passing through DD from the netflix app?
Thanks!
David

To answer my own question and to those having the same issue, it turns out to be a bug in the latest Apple TV software update. Here's a similar discussion: https://discussions.apple.com/thread/6012766?start=0&tstart=0.

Dolby Digital over HDMI failure

I am connected to my Onkyo AV receiver through HDMI and when I first turn my receiver on it displays Dolby Digital but as soon as I start netflix DD goes away. I have tried setting DD "on" and "auto" in apple tv settings. Anyone having any luck with DD?

Ok... I found out that the dolby digital over HDMI issue is no fault of AppleTV. Most content from Netflix is not broadcast in Dolby. A good movie that is in DD is "The Warriors Way". You'll even see the Dolby icon at the main movie menu.

Set Dolby Digital for optical only, not HDMI?

Just wondering if there's a way to set the ATV2 to output Dolby Digital only over optical but not over HDMI? My TV doesn't support DD but (obviously) my 5.1 receiver does. If I leave the setting on "Auto" it just sends a stereo signal to both HDMI and optical, but if I turn it on to "On" then it works via optical but not over HDMI since the TV can't understand it.

I set up my TV as a monitor only and route all sound directly via optical to my receiver. I then muted my TV, and control sound via the receiver.

ATV3 - I need to enable dolby digital for optical surround sound (netflix and home movies), but when I do this it stops audio coming through TV speakers

I have a cinema sound receiver connected to Apple TV via optical cable. When I have dolby digital set to Auto it doesn't come through as dolby digital when watching movies on netflix and iTunes (home movies).
If I set Dolby Digital to ON it works as expected, but the sound stops working through normal TV speakers (via HDMI). This is the same for netflix and home movies.
I tried 16 bit setting, but it made no difference.
Any advice on how I can get this working - meaning Dolby Digital always on for when I turn my surround sound on and sound through speakers for normal operation?
Obviously I can change the setting when needed, its just a pain.
Thanks in advance.

Hello everyone,
here is the friendly and signed driver installation method to enable Dolby Digital Plus in your Encore internal speakers only. This is not an official driver, there is no control panel for Dolby Digital Plus or various sound effects, but tested and has much better and richer surround sound quality as before with factory driver. I guess, this driver tweak can work with any Bay Trail tablet also.
How can you upgrade Encore sound drivers:
1. Download signed driver package and extract.
2. Open Device Manager.
3. Upgrade your Sound, Video and game controllers
- Intel SST Audio Device
- Realtek I2S Audio Codec
one by one with "Have a disk" method.
4. Double click enabledolby.reg file and add to your registry.
5. Restart, and enjoy better sound quality.
Thanks.

Request for THE dolby digital answer from Apple

My old set up was component video and optical into AV reciever. All worked well, HD movies had DD 5.1 soundtrack.
Now my new HDMI set up doesn't seem to send 5.1 across.
1. I have dolby digital set to on
2. I played a known DD HD film 'In Bruges' but no matter what could not pick up DD 5.1 via HDMI, my AV reciever Sony 2400ES (brand new model) just piccks up stereo
3. The soundtrack worked beautifully when sent via optical in full DD 5.1
4. I tried to select the 5.1 audio track via play/pause button which seemed like a great solution just in case both stereo and DD 5.1 were being sent via hdmi and confusing amp, but no selection option exists.
what worries me is the lack of response (that I can find) from apple on what as usual seems to be a huge amount of postings on this subject.
What would be handy Apple are:
1. A FREE dolby digital 5.1 movie/tv episode to 'play with' on with a selectable soundtrack option to allow you to check every option on your home cinema set-up without wasting £4-£5 every 48hrs. And I know the start up movie is said to be 5.1 but it lasts for a few seconds!!
2. A definitive answer on this issue
3. A difinitive LIST of movies and their soundtrack options, why does it take the pre buying screen to confirm/deny that the HD movie is indeed in 5.1, can't you use the same nomenclature as years and years worth of DVD covers, PUT Dolby Digital 5.1 and the little 6 speaker logo not just the double D's, which in DVD land usually just denote dolby stereo.
4. some administrator postings, I can't remember (apologies if wrong) seeing OFFICIAL responses in these forums, just loads of confused owners. And I remember a couple of years ago when my 80GB firmware update rendered my ipod dead, and it took WEEKS to find out how to fix it, which was a roll back until the new firmware was released.
I love 720p movies in 5.1 DD via HDMI, or rather I love the idea of them. It seems daft that to get it all as it should be I need to revert to component and optical

{quote}I played a known DD HD film 'In Bruges' but no matter what could not pick up DD 5.1 via HDMI, my AV reciever Sony 2400ES (brand new model) just piccks up stereo{quote}
In Bruges - in 5.1 works fine on my ATV with it connected to my AV receiver via HDMI
{quote}The soundtrack worked beautifully when sent via optical in full DD 5.1{quote}
It seems that your HDMI input on your receiver has not been configured to accept 5.1. You may need to check the settings of the receiver.
{quote}I tried to select the 5.1 audio track via play/pause button which seemed like a great solution just in case both stereo and DD 5.1 were being sent via hdmi and confusing amp, but no selection option exists.{quote}
This option only exists in 2.3 if you have extra audio tracks (e.g Director's Commentary, Alternate Language). If you have the "default" 2 tracks of AAC Stereo and AC3 then the Audio tab does not appear.

However, no matter if it is a few seconds or not it still plays in 5.1. Again, my ATV to my receiver via HDMI flips over to 5.1 when playing the startup movie, back to Stereo when negotiating the menus then back to 5.1 when i play a movie

I have plenty of DVD's where the Double D logo is shown and then right after it the words: Dolby Digital. Anyway, head on over to www.appletvjunkie.com if you want a list.
{quote:} I love 720p movies in 5.1 DD via HDMI, or rather I love the idea of them. It seems daft that to get it all as it should be I need to revert to component and optical{quote}
Again, no issues here with 5.1 over HDMI. You say you have a brand new receiver - perhaps the settings are not quite right on it to accept 5.1 over HDMI. Just a thought.
I can't see how a "known' film that plays in 5.1 over Optical but does not over HDMI be a problem for Apple. It's not like they can add "Do not send over HDMI" flags.
Yes, there is a big thread on AC3 not working with the 2.3 update, but that is down to the lack of AAC track on peoples own converted movies, and nothing to do with it being sent over Optical or HDMI. I don't believe Apple would be missing the AAC track on a movie they rent.
Cheers

ITunes rented movie not outputting Dolby Digital 5.1 audio

The problem with the downloaded movie (Real Steel HD) is
that the Dolby Digital 5.1 (English) audio is not being putput. The movie is only playing back in
"stereo" mode. When playing back on iTunes there are four audio tracks
to choose from:
1. English 1 (This plays stereo)
2. English 2 (NO SOUND) - I believe this should be the Dolby Digital track
3. French (This plays stereo)
4. Spanish (This plays stereo)
Neither of the two English tracks is outputting Dolby Digital 5.1 audio.
I have confirmed that my PC is capable of up to 7.1 surround sound and
my A/V receiver is capable of even more. I have updated both the ATI
Radeon 4500 driver and the Realtek drivers. I have tested and
confirmed that my PC is capable of outputting sound to all 5 of my
speakers and my subwoofer, HOWEVER when playing back the rented movie
in iTunes the maximum audio is stereo. I have the latest version of
iTunes installed, so that shouldn't be the problem.
I have also purchased another movie advertised as Dolby Digital 5.1
audio (The Bourne Supremecy HD) but I am afraid to begin my 24-hour
viewing period because of these audio problems being unresolved.
My question is: Are there known issues of movies purchased on iTunes
and played back on a Windows 7 PC not playing the Dolby Digital
tracks? If so, is there a fix for this via an iTunes settings change
or a Windows update patch?
From the four audio tracks that I listed above, I believe track 2 is
the Dolby Digital track, yet there is NO SOUND when that track is
selected.
Please help, as this is pretty frustrating when your movie night is ruined for the family especially after you've paid for and waited for the movie to download.

I managed to get my DD tracks working.
First had to update itunes to the latest version (10.7.0.21) to get rid of the out of sync sound problem
Then updated the realtek driver. There was an update directly in the realtek website (mine is the HD Audio): http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24& Level=4&Conn=3&DownTypeID=3&GetDown=false
After all that. I tunes wasn't allowing anymore to select the Doubly Digital 5.1 tracks (an improvement).
Then went to the windows properties for the realtek optical output and checked both options to allow application exclusive access and to have priority (http://dailykermit.wordpress.com/2009/09/11/windows-7-exclusive-device-control/)
After all this, I was able to enjoy my rental

Dolby digital through HDMI

I have a 2012 MacBook Pro with retina display. I'm trying to get Dolby digital through the hdmi port and after comparing some media attached to my receiver the same movie was Dolby digital on my WDTV and using the same cable was stereo connected to my MacBook Pro.
I'm not sure if its a setting or an atypical apple thing like they did with the digital stereo connection in headphone jack using a mini fiber optic cable (phoslink).
I suppose if I want to hear Dolby digital out of my Mac, I wondering if I need a thunderbolt to hdmi to get what I want. Dolby digital through HDMI is an industry standard!

After talking to three levels of support, I finally was told the new Macbook Pros (with Retina display) are NOT capable of producing Dolby digital through the HDMI port. They only do digital stereo.
In order to produce up to 8 channels of Dolby digital surround sound you must use an additional toslink cable, which is a mini fiber optic, found cheap at Monoprice!
Just for the record, the expensive Thundebolt to HDMI or mini Display port to HDMI only do stereo too. Not a big deal for most, but upsetting if you're expecting a HDMI to function as it does in any other piece of equiptment!!

P7NGM-digital : audio over HDMI ?

Hello,
I read elsewhere that for this board, P7NGM-digital, audio over HDMI was not possible ?
Is it true ?
As it is not working for me.
JP

Problem solved. Uninstalled all windows updates and display drivers. Reinstalled windows updates in groups of no more than 5 at a time, restarting after each group. Installed latest Intel display driver, restarted. Works like a charm now.
