Dolby Digital - Handbrake

Hello
If I have decoded my DVD collection into iTunes and selected 5.1 on the audio decode. Should these play on the Apple TV 2 in Dolby Digital? Or have i decoded wrong?

We're not supposed to discuss this sort of thing - think about it though, you want software that predates Apple TV version 2.0 to specifically do something only added in 2.0...

Yeah Handbreak upgrade now does Dolby Digital 5.1!!!

http://handbrake.fr/
Handbreak can now create MPEG4 files from DVDs in the exact format like the one purchased from iTunes.. so can be played on AppleTV, iPod, iPhone etc.
MPEG4 with H.264 video, Audio Tracks can choose Dolby Digital 5.1 (AC3) + Dolby ProLogic II, Audio Track 2 - whatever you want.
tried it last night work flawlessly and is about twice as fast encoding as before (not a carefull test but it was WAY faster)
and it's free!!

Can anyone please help me on this, if you guys can check is the 2-track option available while watching movies on iPad 2... or is it just me who is unable to find it despite these movies being encoded in DD 5.1

Encoding Dolby Digital 5.1 (AC3) sound in MP4 files using AC3 pass-through

Looking for an application that will encode Dolby Digital 5.1 (AC3) sound in an .mp4 container using AC3 pass-through for playing videos with surround sound on ATV.
Handbrake is out of the question because I run Tiger. The Tiger version cannot do AC3 pass-through.
Visual Hub is no longer available.
Any other options?

You may need Apple's MPEG2 QT plugin as well for MPEGStreamclip.
Also, consider if running windows in parallels/Boot Camp etc that there's a windows version, and possibly a linux version.
VisualHub code was released open source - Google FilRedux and PunyVid (iSquint derivative). Not tried either though.

Dolby Digital 5.1 Question

I used to have an Apple TV (Gen 1) that I streamed my ripped DVD collection to. I had create the files using Handbrake (AC3 Passthrough). Then, after a "patch" by Apple the Dolby Digital stopped working. Fed up, I sold the Apple TV in frustration.
Some time has passed and I've recently gotten an iPad 2 and I really like the potential of AirPlay. I am considering picking up the new Apple TV but only if I'll be able to play files with AC3 included. Can the new Apple TV play AC3 files either through the HDMI cable (preferably) or the optical cable?

The apple tv seems to be notoriously iffy about passing through Dolby Digital from non-iTunes bought material.
Since getting the ATV2 I have not been able to get it to work as it used to in the ATV1.
First problem was that you had to play a iTunes bought movie with DD which would then allow passthru to happen on all ripped material as well... weird but at least a work around. If you tried playing ripped material (from handbrake for instance) it would just fail unless you turn DD off or play an iTunes movie with DD first.
This week the ATV2 did another update and now even with DD on auto doesn't work for iTunes bought material. You have to explicitly turn it on for DD to work at all but then none of the ripped material will play any audio at all if it has a DD track.
Turn it on and iTunes will passthru DD from iTunes movies but ripped material won't. Turn it to auto and nothing with passthru DD. Turn it off and everything plays on PCM from AAC track (as expected)...
Seems a bit like we are going backwards here.
I'm starting to think Apple don't have any regression testing for this feature at all.
I read in another thread that apparently the trick is to set the DD track as disabled in the mp4 container and then it will work. I don't see why this is needed at all and seems very picky on the software's side. I still need to investigate this to see if it's true, but most tools out there will not do this and thus the material won't play on the ATV2 in surround. It a real bummer as that is my main reason for having it in the first place.
90% of my material is ripped DVD's and Blu-rays. I am forced to watch them all in stereo now or fall back to a DVD player...

Can't stream Dolby Digital movies from iTunes to Apple TV 2 since iOS 4.1

Has anyone the same problem?
Since I updated Apple TV to 4.1 it's not possible to stream movies with Dolby Digital sound to Apple TV anymore. When I try to start playing the movie I get this error message:
The operation coulnd\U2019t be completed.
(BackRowErrors error 326.)
This problem didn't appear on iOS 4.0. Videos with stereo sound still work, so I think it has something to do with the Dolby Digital. I encoded the videos using Handbrake.
Thanks for any help!

I was having the same error. I switched Audio Language to default and Dolby Digital to 'on' and I finally can see the video, but with no sound...
I tried MKVTools and Handbrake, AC3 passthru for audio on both, iTunes plays nice, but Apple TV doesn't. Any other solution?

Perhaps silly, but, can Garageband take Dolby Digital 5.1 Input and record?

Using the built in mini toslink on the Mac? Or, can it simply do stereo? I see no reference to digital, or, AC3, or, TOSLINK or anything else in the help.
I have a music source that outputs dolby digital and want to be able to accept input from it.

Didn't think so, have searched the net for products allowing me to use the digital input, have not found any yet. I see things like Handbrake that allow me to convert say MPEG2 movies with DD content, but, what allows me to input the content in the first place?

IOS 5 update won't play 5.1 Dolby digital sound

I just updated both my apple tv 2's to iOS 5. Now, in order to get sound out of my movies that I used the apple tv 2 settings in handbrake for, I must turn off Dolby digital. They worked fine before the update. Any suggestions?

Just got of the phone with Apple Support, and they have esculated a case to Apple Enginnering

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.

Dolby DIGItal HOME THEATER cannot be installed after upgrading to Windows 8.1

Hi there,

I have lenovo edge E531 with 8gb ram, intel core i5-3230M 2.6GHz, GeForce 740M

hi sotim01,
Thanks for posting!
1. Uninstall all components,
Open Device Manager and Uninstall your Conexant audio under Sound and ganing controllers (make sure to place a check under delete driver software for this device)
2. Open Control Panel Uninstall a program and highlight the dolby component and an Uninstall button will appear.
3. Open your C: drive and Delete any folder that says drivers if non then continue with the next step
4. Download this Driver for installation
Conexant Audio Driver
Install it and continue
5. Open Drive C: now and you should have the Drivers folder back.
Open that, Open Connexant Open Dolby Gui, then you should have Dolbyaa for Advanced audio.
Restart your PC and there you go!
Let me know your findings
Cheers!

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.

G510 Dolby Digital Plus Advanced Audio doesnt work driver problem with Windows 8.1

Hi,
my Lenovo G510 has Windows 8.1 64-bit.
In the system menue of Hardware and Sound I can see two entries:
1) Dolby Digital Plus Advanced Audio
2) Dolby Digital Plus Advanced Audio (32-bit)
Clicking on the first entry a control panel appears. Does this mean that Dolby Digital Plus Advanced Audio is always running in the backround? There is no entry in the systray.
Clicking on the second entry this error message appears:
Your current installed version is 7.3.2.2 of the Dolby Digital Plus audio driver. The software needs the driver version 7.5.1.1. Installe a correct combination of driver and software.
What to do with this? I searched for a solution and drivers but couldn´t find anything.
Thanks for your help.
Solved!

Media Encoder PCM or Dolby Digital Settings change preset????

I am about to Encode a 2 and a half hour project from PPRO 5.5 into Media Encoder.
If I set my format to H.264 Blu-Ray and my Pre set to 1440 x 1080i 29.97 High Quality, My audio automatically sets to PCM Audio? Why?
When I use the H.264 Blu-Ray with my Pre set to 1440 x 1080i 29.97 High Quality, and I Press the Dolby Digital as my audio instead of PCM, my Preset changes to Custom. (1440 x 1080i goes away)
Why is this? Is that what is supposed to happen?
I had read that Dolby takes up less space without losing that much quality.
I'm trying to encode this file to about 15GB with keeping the best quality Audio and Video I can.
PPro CS 5.5
Media Encoder 5

Jim,
In case you missed it, his program is 2hours 40 minutes, so in that case, space is at a premium and I would go for the Dolby.
It is normal for Media Encoder to create PCM audio, that is OK, Encore will TRANSCODE it to Dolby later and shrink it down.
Edwurd, please see you other posting for more info about encoding size
Thanks
Jeff
Jeff is right.
Let Media Encoder make the .264 and .wav files and have Encore automatically transcode the pcm to ac-3 (since it's licensed to do so and AME is not). Don't multiplex them into a mp4 or mov container; it'll make it blu-ray illegal (even though Encore will allow you to import it).

I have a Symphonic 32' HDTV (Dolby Digital Plus). can someone help me figure out how to configure it optimally with my Mac Mini? the display and sound is off. Do I need drivers/software? I'm new to macs.

Hello, since nobdy else has replied...
Long shot, but...
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there.

Dolby Digital Auto Setting Doesn't Work w/4.4.2?

I have a bunch of old movies that were recorded in stereo, pre-Dolby, and of course, a bunch of newer in Dolby Digital. After upgrading to Apple TV iOS 4.4.2 yesterday, I now find that the Settings/Audio & Video/Dolby Digital/Auto setting no longer works.
I just started a new iTunes downloaded movie with Dolby Digital 5.1 sound and noticed that it was playing in PCM stereo-only mode for some reason. I then tried a couple of other older iTunes downloaded movies with 5.1 sound, and they all were playing in the same old PCM stereo mode, as well. To get the new movie to play in 5.1 sound, I had to manually change the above Dolby Digital setting to ON.
A similar issue applies to older movies in pre-Dolby stereo. If the above setting is set to Dolby Digital ON, those older movies switch from normal stereo to Dolby Digital 1.0/Center channel only sound, so I have to either switch the Dolby Digital setting to OFF or back to Auto, which defaults to PCM stereo for everything now.
Is anyone else experiencing this change? The Auto function worked perfectly for me before this upgrade.
I'm using an Apple TV 2 with an optical connection to my audio amplifier. The movie is streaming over my wired gigabit Ethernet home network from my iMac.

Seems to be an issue for some of us since 4.4; see other thread.

HD TV Show... can't get Dolby Digital 5.1 to Work

I just bought an episode of Chuck (from NBC). In the description of the show it says that it has Dolby Digital 5.1 Surround Sound. I have my macbook-pro hooked up to my surround sound system using a mini-toslink -> optical connector. When playing the episode the Stereo track plays just fine... but if I switch to Surround.... I get no sound.
Any ideas?

I bought LOST season 5 season pass.
I only found out about this 'non-feature' after trying for ages to get it to work and searching for a solution.
When I first complained I got told by support that it was probably a hardware issue and to call the support line. I did, got the same answer, and was then asked to part with more money for continued support, which I declined. I asked point blank whether DD5.1 really only plays back on Apple TV - which was denied.
After continuing to pursue it I finally got an email from 'tier 2' support admitting that 5.1 does only plays back on an Apple TV: here's the text:
+This is+ name removed +from iTunes Store Customer Support and your request+
+has been escalated to me today. I understand that you have been+
+unable to use Dolby surround sound on your computer for your iTunes+
+Store purchases.+
+Dolby 5.1 surround sound is currently only available for the Apple+
+TV. Apple recognizes that no one is better qualified to provide+
+feedback about the content provided on the iTunes Store than the+
+people who use it.+
I got back to them to say I'd like a (small!) partial refund - to cover the costs of my phone bills and disappointment. They've gone silent.
I've now reported it to Trading Standards in the UK as it is misselling. Curiously - since i complained the 'About HD' section - where it used to say +on your Apple TV or Computer+ has been changed.
