Apple TVs digital out

What 2-channel audio format / sample rate is coming out from Apple TVs optical digital out, 16 bit/44.1 Khz, 24 bit/48 Khz or 24 bit/96 Khz?

All I know for certain is that it outputs bitstreams/PCM.
My AV amp is fairly old and does not decode anything other than PCM/DD2.0/5.1/DTS.
DTS can be store in a .wav file and some have managed to embed DTS in movies but it's fiddly. Search Diatonis for some demo .wavs.
The compressed formats seem to get converted to PCM - frankly if they're compressed, the bit depth and sampling frequency are not hugely important unless you're concerned the output is higher than your amp can accept. Unfortunately my amp doesn't tell me the parameters for PCM fed to it, but as DD/DTS aren't shown then by exclusion it's decoding to PCM as I'm only connected via optical.
I suspect on balance it will output 48kHz and 44.1kHz in 16 bit, as I've recorded some vinyl at these rates, saved as .wav, and played back on AppleTV. Pretty sure I recorded something at 96kHz and 24 bit (maybe 16) and it played it back but whether it downsampled output I have no idea.

When I unplug Apple headphones from my MacBook Pro sond from internal speakers not work, and system soud preferences displayed: Output: optical digital out port only

If you see a red light in the audio output port, then the internal switch is stuck. Insert the earphone plug a few times and see if you can trip the switch. If that fails, insert a cocktail stirrer and the like and jiggle it around inside. If that fails, take it to an Apple store and have the technicians at the genius bar do it for you.

Audio problem with one episode of iTunes tv show on two apple tvs but audio works fine on same show on iMac

I have a season pass to Dr Who and all 30+ other shows purchased on iTunes work great. Last night's episode (Hide) has a hissing sound so loud it drowns out all the audio in the show when i try to watch it on my Apple TV. I then downloaded the episode to my iMac and my iPad and no audio issues there. However when I tried playing it shared from my iMac to the Apple TV and the audio problem was there again. Same thing happened when I tried to AirPlay from my iPad to Apple TV.
I have two Apple TVs. One is latest model w latest upgrade, the other is generation before without latest upgrade. Same audio issue on both. I have tons of iTunes TV shows and movies and this is the only episode with an issue. Something is wrong with this file that causes it to screws up the audio on Apple TV.
Has anyone else seen this kind of audio issue specific to just one TV episode or movie? Anyone know support path for iTunes problems?

If other episodes play Dolby Digital fine this could be a file encoding problem - they sometimes get it wrong.
I suggest you all contact Apple about the problem via itunes store support here:

@Chris:
I was just referring to the visual graphics (you know, the fireworks, stars and other stuff that reminds me of the 70's....) that you can play on the screen when iTunes is playing music?
I noticed that these effects are not just randomly chosen, they are in fact synchronized to the beat and intensity
of the music, and that struck me as rather cool......

Why is my Apple TV cutting out when watching TV and Films?

Hi there, will try to provide as much info as possible but let me know if more is needed.
I have purchased the newest Apple TV (March 2012) recently, and have noticed that it cuts out when I'm watching films and TV shows, but never when I listen to music or the radio. My friends have also noticed they cannot play youtube videos off their iPads onto the apple TV. When it cuts out, it does not say "cannot connect to iTunes" or anything similar to that, it just returns to the home screen and then we can select the computer and TV programme and resume playing as normal. This happens every 5-10 minutes during a show/film though and does get incredibly annoying.
Originally I felt it would be a network problem. We have BT Infinity and the Home Hub 3.0, and I am aware that lots of people have issues with this. However this problem doesn't happen on any other device, nor when playing music. It is specifically when watch movies and TV shows. I have actually swapped the home hub device for a Netgear Cable Router back and forth trying to see if it ever made a difference, and the same problem is still happening therefore I do believe it to be a problem with the Apple TV.
I have checked the troubleshooting advice for the Apple TV and followed that and nothing seems to have helped (unplugging various bits, making sure i'm on the right channels etc.).
In short I have literally no idea what could have happened and what to do about this, and before I actually rang apple I wanted to know if anybody new anything about problems like this and how they can be resolved.
Many thanks.
PS it is also worth noting that on our homeshare, we can no longer access one of our friends iTunes, despite it being visible it never loads and is invisible to the Apple TV. This also baffles us and we are not sure if it is related!!
Can;t think of any other details but let me know!

I have three Apple TVs at home (one 2nd Gen and two 3rd Gen). I have not had this issue. Worst thing that happens is it will not load my content from iTunes after waking it up, so I reboot the Apple TV and that fixes this.
My Dad has a 2nd Gen and it has started cutting out or dropping during playback of movies from iTunes and Netflix. I tried restoring it over WiFi and also directly from his iMac running Lion and the version of iTunes previous to the latest that changed the iTunes layout (Not sure of the version), but it would fail saying the download was corrupt. I even downloaded the .ipsw file and tried manually restoring that way, but it failed as well. I purchased the USB cable for Apple TV to do this.
I just took it home tonight and tried restoring on my iMac running Mountain Lion and the latest version of iTunes and it worked. I will bring it back to my Dad's and test it there. I will post the results.
Maybe try this and see if it works. I noticed that doing it through iTunes that it said it restored the latest version of OS for Apple TV and also the Firmware.
None of the Apple TVs mentioned have been Jailbroken, so not sure if this would be causing issues for anyone else. Just trying to rule out anything I can think of.
I didn't get a chance to try this next step, since restoring from my iMac worked, but this was going to be my next step:

What is the maximum number of Apple TVs (3rd gen) you can connect to 1 Mac running iTunes?

I have one Mac with my digital library running iTunes 11 and seem to be having problems keeping Apple TVs connected (via home sharing) when I get up around 10 Apple TVs on the network.
The Mac is running Mountain Lion with all software updates installed, iTunes 11, and the Apple TVs are all running 5.1.1 (the latest at this time).
I am not asking how many computers can authorize via iTunes to use the same Apple ID - that answer is 5. I have read in multiple places that the number of devices (e.g. Apple TVs, iPods, iPads - not computers) that can sync content to an iTunes account is unlimited, but I don't think that's entirely true.
I'd like to keep this conversation about the number of Apple TVs you can have home shared to a single Mac / iTunes library via home sharing.
I am also not asking how many a network could support via concurrent streaming, etc. That's not relevant. We only use 1-3 Apple TVs at any given time simultaneously, and streaming simultaneously to as many as 3 Apple TVs hasn't ever been a problem.
I recently upgraded all my Apple TVs in this house to generation 3 units - I have 12 of them in all, but once I connected about 10 of them I started having problems (at least I think it was 10).
Does anyone know the official limitation (if there is one) ?
The problem that I am having is that even though I have a great Wi-Fi N or wired gigabit connection at each Apple TV, and the correct home sharing Apple ID on each Apple TV and iTunes on the Mac, when I try to access "Computers" via the Apple TV menu, I get this error:
Could not connect to "My Library": Make sure the computer is on the same network as your Apple TV, the iTunes version is up to date, and iTunes is running.
Now if I restart iTunes, I can get the Apple TV I am currently troubleshooting to connect, but then if I go to a different Apple TV, it gives me the same error. Restarting Apple TVs doesn't fix it, only restarting iTunes seems to. But I can't seem to get multiple units to see the Library simultaneously.
Thanks to anyone who provides help on this.

Apple TV is by it self in a category.
With Apple TV 1 the limit was 5 Apple clearly stated that. The reason? Probably because the Apple TV 1 had a hard drive and was able to store content locally (quite a bit actually). This would make it more in line with authorized devices.
You authorized device limit is 5 but this does not pertain to home sharing again something different.
When you play content from an Apple TV you are streaming from an authorized device and as long as you have the same iTunes account on that Apple TV as the iTunes you are connecting to you will be ok.
Now to the error. I have also had this error and I had it on a network with only 1 Apple TV connected and it is since iTunes 11. It seems every time Apple updates iTunes it has a bad effect on Apple TV. So I would not relate this error to the number of Apple TV's you have, every time I get this error I restart the Apple TV and its fine again.
On a side not I used to run MANY Apple TV's off my xserver. I had my families homes networked with VPN. I would prefer to not say how many but it was quite a few. biggest problem there was multicast over VPN....whole other story.

Multiple apple tvs to one iTunes and iMac

I installed 10 apple tvs in my office all linked to 1 iMac.
I just found out that I can only access the iTunes on only 5 of the apple tvs.
Is there a way to access all ten from one iMac using 2 iTunes accounts at the same time?. and how canister de authorize some of the apple tvs from the iTunes account ?

Apple tv's always sync through itunes. you can either transfer content to a computer that you would have at each residence or sync content in Saskatoon and then move the apple tv to each residence. you could not add to the connect if you usually buy through itunes, but if you buy content on the apple tv itself then it should pose no problem, however if you buy content on the apple tv it will only be on that individual apple tv.

Multiple Apple TVs - one iTunes Host ?

Is that possible at all ? I would choose Apple TVs to equip a building if it is possible to hook them up to one iTunes host.
I've built similar systems for audio, with Airport Expresses.
A second question I couldn't find an answer for:
Is there password protection for streaming access from a mobile device ?
I don't want guest A to be able to stream his stuff to room B....

yes, providing your network has enough bandwidth to handle all the traffic.
the original appletv had a limit of 5 devices to 1 itunes library, not sure if the new one has the same limit as it is using a different method to connect to itunes (HomeSharing).
A second question I couldn't find an answer for:
Is there password protection for streaming access from a mobile device ?
I don't want guest A to be able to stream his stuff to room B....
that is AirPlay you are talking about, and that isn't available yet (that only comes with iOS4.2 which isn't out yet).
so until that is released, you won't find an answer to that. however i doubt there will be password protection for that.

How many Apple TVs can login to one Flickr account?

If I have twelve Apple TVs in different conference rooms, can I have all of them login to one Flickr account so they can all show the same photos on their screensavers? I couldn't find this on the Flickr site so I figured I'd try here. Thanks to anyone who can offer up an answer.

In addition to accessing the Flickr site, Apple TV also supports connecting to personal Flickr accounts. I want to connect twelve apple TVs to one personal Flickr account and wanted to find out if anyone knew if there were limitations to doing this. I'm trying to avoid finding out down the road that this results in some sort of problem and creates an issue at the wrong time resulting in a bad user experience.

How many apple TVs can you have on one network 5, 10, 15, infinite?

I have an application where there are many rooms and I would like to be able to use Airplay in each room, can I buy 10 or more Apple TV units and put them all over my house on my wireless network and be able to airplay to any one of them? What is the limit of Apple TVs that I can have in one area. Has anyone tried this? How many have you maxed out at? What is the limitation?

There is no specified limitation but you will encounter a practical one. It will be a function of the numerous and generally unpredictable variables that affect any wireless network.
Ten Apple TVs is certainly within the realm of possibility though. This post reports success with fifteen of them.

Help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

IPads, iPhones, and Apple TVs can no longer load home sharing library after 2 years

I have been using home sharing for the past few years and streaming my music, movies, and TV shows to my Apple TVs, iPads, and iPhones. A couple weeks ago it stopped working. On all the devices I see the library (Familys Library) but when I go to load it fails to load. The iPads and iPones get to about half of the circle and fails. On the Apple TV I think the message just is "Cannot load Library"
I have tried restarting all of my devices but that has not helped. I changed the account that the home sharing is setup for and that did not help. I rebooted the Windows machine multiple times. I disabled home sharing, rebooted, restarted home sharing, all to no avail. The library system is connected over Etehrnet so I made the system to a different port on the router with no luck. I have also unplugged the router nad plugged it back in, also with no luck.
So, I will try replacing the ethernet cable but I do not see that as being the issue. It seems like something on that computer.
Going through the Programs it looks like iTunes and Quicktime were both updated on 3 June, right around the time this started to occur. I also loaded items for my duaghters Nook, Adobe Digital Editions, so that she can get books. I removed the items that I loaded for the nook and that did nto fix the issue. I would like to downgrade iTunes, but I cannot find an old copy of iTunes plus I do not know if this will destroy the library contents.
My questions would be
1. Can I find an older version of iTunes
2. Can itunes be removed from the computer and reinstalled without the iTunes library getting blown away? I have a lot of moveis and descriptions and information located in the Get Info that would just stink to lose
3. Could this be a corrupt library and is there a way t verify the library?
4. Any other things I can do and check
Thanks for any insight and help
Cheers
Dave

All the cutting and pasting and I forgot the machine information:
OS: Windows 7 x64

Sound Blaster card 'digital out' into my high-end stereo receiver?

BSound Blaster card 'digital out' into my high-end stereo receiver?A I want?to interface my iTunes music library?(all tunes in Apple Lossless file format) to my high-end sound system, using an optical (TOSLink)?cable and a "mini TOSLink adapter" that will plug into the 'digital out' jack on the Sound Blaster card in my Windows XP PC. This configuration will take advantage of the high-end DAC's in my Denon receiver.
I don't care about getting surround sound out of my PC, and I'm not a gamer. I just want hi-fi stereo music from my iTunes library.
Will this work?Can I expect CD-quality sound?
Also, would it be worthwhile to upgrade my model SB394 sound card to a hi-fi SB card like X-Fi Xtreme Audio, or is any sound card as good as any other for simply deli'vering the digital data stream to my Denon receiver?

well, I have two devices that a combo CD player/Tape decks/radio tuner/amp; one has misc input, the other doesn't. Both are analog devices, both are old things I bought at a yard sale.

But I wonder, what considerations do I have to have?
Firstly, is the Aux In on my board analog or digital? I'm assuming if it doesn't say "digital", it's analog; correct?......
secondly, and more importantly; the CD/Tape/Tuner/Amp thing is supposed to be used with 8 ohm speakers and do I have to worry about sending too much current to the soundcard?
specific model of SB card; I'm not sure. It has 2 analog outs, analog in, mic in, digital out and a joystick port; and it came installed on a 200 Dell w/ Win ME
and please, don't try selling me something; I use old crappy hardware and really do not mind doing so.
any help will be appreciated, thanks.
Aux-In is an analog port (4-pin connector/stereo).
Don't connect powered output (= speaker outputs) into soundcard but, if possible, use some low-power connection like Headphones-Out (or if possible then some line-out port).

I can't run Itunes! After installing Itunes, I receive a message saying that Windows could not verify Apple's digital signature and it closes.

Pls HELP me! I can"t install it Itunes on any of my computers. After downloading it ( Run now or Saving it) it will no run because I keep receiving a message saying that Windows can not open this file because it could not verify Apple's Digital Signature. I have changed my internet security settings to allow downloads from unverified websites but it will not allow me to run Itunes. I had an older version of Itunes so I tried to install the update and it wouldn't work because so the same message about not being able to verify the digital signature. I uninstalled Itunes and Quicktime and all other Apple programs on my system. Then I tried to download it again... no luck the same message came up again. I then went to my other computer that NEVER HAD ANY APPLE software on it and tried to download Itunes. It gave me the same message. Please help me, I'm going crazy tring to figure this out.

I had this same issue occur today during update, searched and finally tracked to problem with windows registry. Used online version of windows registry tool "Fix It" (can also download portable version for offline check. I selected Apple updater utility from list to fix and it did it's thing. Returned to my downloaded 10 iTunes adn isntalled perfectly fine.

Using ATV2/3 with non-HDMI Receiver and theater projector and also need iTunes downloaded movies to work. I'm thinking to use the Toslink digital out for surround sound and an HDMI to RGB converter for video but not sure the iTunes DRM will prevent?

I have a theater with a Runco projector but non HDMI. alas, my receiver is non HDMI. Changing electronics and projector is a non-starter.
I would like to be able to buy HD movies on iTunes and watch them by streaming via Apple TV3. My plan is to capture surround sound from the TosLink digital out, which my preamp/receiver can handle. For the video, I need to convert the HDMI to RGB component to feed my receiver.
This is where iTunes DRM and HDCP issues might arise. I am under the impression that I need an non-HDMI compliant converter so that ATV3 can even talk to my receiver. It is my understanding that this is possible and takes care of the HDCP issue. But what about the DRM issue? All I want to do is buy and watch HD movies, no bad intentions. I find it incredible that iit might not be possible.
Anyways, is there a 100% certain approach even if it costs up to $300-400. Again, changing hardware is a non-starter so please avoid the obvious "buy an HDMI amp and projector".
Thanks
