HT1551 digital toslink audio output is restricted on apple TV

I am trying to connect the apple TV to a receiver via the toslink output. All that I got on the receiver is a message that says "digital signal restricted". The apple TV was previously connected to another receiver via HDMI and I had tested the toslink connection before and it was working. Should I reset the apple TV? Have somebody faced the same problem? Please, I would appreciate any help
Thanks

Never heard of that before.
It either sends linear PCM 16 bit 48 kHz (not 44.1 kHz) for stereo or Dolby Digital 5.1 streams.

How to connect Digital Optical Audio output iMac with Receiver Input

I have connected iMac with onkyo hts-3300 home theater system receiver through optical audio TosLink Cable.( http://www.amazon.com/Digital-Optical-Audio-TosLink-Cable/dp/B001ZU3G2I/ref=sr12?ie=UTF8&qid=1292865309&sr=8-2 ). Unfortunately there is no sound coming out from the Home theater system. I have verified the Receiver optical input is working fine by connecting with my TV optical audio digital out put and the it's working great. The only difference between TV and iMac is, on my TV, it has optical audio digital output and I can use this cable (http://www.amazon.com/Tripp-Lite-A102-02M-Digital-connectors/dp/B0002WPREU/ref=s r11?s=electronics&ie=UTF8&qid=1297320792&sr=1-1) to make it work. I can also verified my optical audio TosLink Cable working because I can see the red light coming out from the cable. So the only problem could be from iMac. I doubt I need to change the additional setting to configure iMac to use external optical audio setting instead of the buit in audio setting. Hoe can I able to do it? or my iMac(IMAC 21.5"/3.06/2X2GB/500GB/9400M-ITP
MB950ZP/A) doesn't support optical digital audio out put? I have follow this thread http://discussions.apple.com/thread.jspa?messageID=12769423&#12769423 and to my surprise which doesn't work out for me. I doubt that i need to change some setting, but when I got to setting>> sound I cannot change any setting. I was quite depressed aldy. Can someone answer my question as i m a newbie here. Thanks a lot

Thank you very much for your reply.
@Király : May i know how to Open Audio Midi Setup? Is this Audio Midi Setup is in the locatated in the Setting in Mac Snow Leapord OS? or how to locate this "Audio Midi Setup " in Mac enviroment. Is it possible to open this Audio Midi Setup in windows 7 enviroment also? I Just want to get the audio from my iMac in Hts-3300 onkyo home theatre. YOur help is much appreciated
@rkaufmann87 : Thank you very much for your sharing about this http://www.apple.com/airportexpress/ connection. for me what i understand is the digital audio output in airportexpress is the same as the audio out put in iMac in terms of details sepcs. So this airportexpress will only help you connect wirelessly to home theatre system, rather than waired connection. Other than that nothig much difference. So there is no point for me to spend extra bucks to attain the wireless connection. Unless the airportexpress have optical digital input, which i believe not. Correct me if I m worng, thanks

Does digital optical audio output "sleep"?

Digital audio works fine as long as an application is actively generating audio, but when it is paused for a short while, I start static from my amplifier similar to what I hear if an optical cable is disconnected. I notice that there is no light coming out of the end of the optical cable. This was a problem in setup, as the absence of light caused me to think that the optical cable was damaged or not properly connected.
Does the optical audio output "sleep" after a period of nonuse and lose carrier? Is there a way to keep it active all of the time?

I've also been having this problem with my Mac mini (2009 version). Static/crackle sound over digital connection when the audio has been idle for a short while.
It reminded me of an old problem that some PowerBook G4 users had several years ago, where the audio hardware would go to sleep to save power and there would be a delay while it woke up. I remembered that there were a coupe of utilities created to remedy this problem by playing silent noises at short regular intervals.
I tracked down these utilities - KeepSoundAwake and SoundOn. Someone mentioned that SoundOn used a whopping 1% of CPU and showed a Dock icon, while KSA usage was usually 0% and had no Dock icon. So I decided to try KeepSoundAwake.
Here is a link:
http://mrfeinberg.com/KeepSoundAwake/
So far so good. I've been crackle-free for the last several minutes since starting up the program. This is a pretty ancient application (last update was a fix for 10.3 compatibility), so there are a few things to be aware of. I now have this one non-intel-native app running constantly, which is sort of a bummer - but with 4GB, I'm not too concerned. The PrefPane that comes with it will not run at all since it is not intel-native, but the default settings are fine so that's not really a concern either. You do need to make the app a startup item so it will be running all the time.
If I encounter any problems with using KSA with my setup, which includes running some multi-channel audio through Plex, I'll report back here.
I do wish Apple would officially address this issue so we wouldn't need to use a 7-year-old hack!

Audio output keeps switching to Apple TV

My MacBook Pro 2.8 GHz doesn't support Airport Mirroring, yet every time I wake up my computer or come into range of my Apple TV it switches the audio output from my internal speakers to Apple TV. Only about 1 second of audio comes through the Apple TV, and then that stops too. I have to go into System Preferences, select a different output, then reselect "Internal Speakers" before I get audio back.
It's getting really annoying to have to do this half a dozen times a day. Any tips? Thanks!

If, If you use LogMeIn, blame their sound driver.

Can you redirect the audio output of iTunes via Apple TV?

I currently have iTunes running on Windows XP with an Airport Express connected to my home stereo. I toggle the iTunes audio between my PC and the Airport Express via the iTunes speaker setting. With Apple TV, will I be able to toggle the audio output from the Apple TV interface?
Thanks,
Chaaad

No, you can use AppleTV like an Express to have audio playing in iTunes relayed to it, but you can't play something on AppleTV and direct the output to the Express.

Mini digital/analog audio output

I'm using my Mini for itunes music (AIFF) with my home entertainment system. It's pretty high end and I want my receiver to handle the DAC. Is the HDMI output from the Mini digital? Can I make the output digital?
Should I consider going out the USB to a DAC and then to receiver?
Thanks

Should be HDMI. It's got the highest bandwidth -- it can basically pipe 8 digital audio channels uncompressed -- and you can rely on the DAC in your receiver or pre-amp to do the work. If your setup is good, the DAC in your receiver / pre-amp should also be good.
Others may be able to speak to the USB > DAC question. I'm not an terribly well informed, but USB has got lower bandwidth than HDMI, and is not really tuned for A/V delivery. That said, I've read some good reviews of USB > S-PDIF / Analog Stereo DACs.
Finally, I think that S/PDIF is going to be pretty heavily compressed for anything above simple stereo, so if you're interested in high performance 5:1 or better, it's probably not ideal.

How to get the Mac Mini Digital Audio output at 192kHz?

I have a mid 2011 Mac Mini (and love it). According to http://support.apple.com/kb/HT4806, "The headphone / line output port accommodates digital optical audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS)."
So there is digital audio output to 192 kHz but how do you configure it to work? Using the Audio Midi Setup Utility, I can set the sample rate to 96000 Hz -- but it won't go higher to 192kHz. Anyone know how to do this?

That is in some ways confusing. For the analog output, the
internal DAC can support 24 bit/192Khz audio data. It does
require an application that has the capability of playing back
such material.
The TOSLINK optical standard does not support this data rate.
It has nothing to do with the Mini, it is the standard itself. The
TOSLINK optical spec is 96 kHz, 24 bit stereo (uncompressed).
The mini will however support multichannel, 24 bit, 192 kHz
(uncompressed) via the HDMI interface. Also, again,
the playback software needs to support it.
Just as a final note, unless the source material has the
higher sample rate format, there is no benifit to outputing
at the higher sample rate, especially if the source some
lossy comporessed format (mp3, aac, Dollby and DTS
non-HD formats).

OS X 10.8.5 mac mini hdmi audio output issue

I am running a 2012 Mac Mini with OS X 10.8.5 and my Mac is set for audio and video output via HDMI to my AV receiver / TV. I have recently noticed that HDMI audio output ceases to function once the computer goes to sleep. A full computer restart is required to resolve the issue which is an inconvenience to say the least.
Or is anyone aware of a simple fix?
All my software is up to date, the HDMI lead and connection works fine for video and audio works fine after a restart so it must surely be a software error. Worked fine until the latest OS X update...
Grateful for any help!

Digital audio input via mini jack/toslink from ADA, monitored via USB audio output... is this do-able? I know digital audio input should be okay but how do I monitor it, apart from using the internal speakers?

Digital audio input via mini jack/toslink from ADA converter, monitored via USB audio output to amplifier... is this do-able? I know digital audio input should be okay but how do I monitor it, apart from using the internal speakers?

You can output audio thru HDMI, with appropriate adapter.
You can use additional cheap external usb audio for monitoring.

Mac Mini Digital Audio Output

Hi,
My friend is trying to use the only audio output from the Mac Mini (1.42 GHz) as a digital out. He was under the impression that when you hook up the right cable (which has bought and we double checked-optical audio cable with Toslink adaptor.)
But when we go to pref. menu there is no selection for digital audio out except for the regular line out.
Any ideas or tricks to getting digital out on this Mini?
Thanks,
Babak

Does he have the 1.42ghz G4 Mini? If so, that model is not a digital/optical audio out jack, at least not the 1.42ghz model I have. Did not check to see if a later update prior to the intel switch added the port to that model. My 1.66Ghz intel mini has the digital/optical audio out. Tell your firend to check the manual that came with his mini, it will tell you if it is a digital/optical out port or not.

Optical/Digital Audio Output from MacBook

So I am interested in hooking up my MacBook to my HDTV so I can watch movies with it. I know for video I need to get a mini-DV to HDMI cable. That's easy. But what about audio? I would ideally like to have playback in surround sound. I have read that the headphone audio output also doubles as an optical output. Is this true? If so what cable can I buy and will it output surround sound from a DVD movie?

Yes, the audio port doubles as an optical in and output. You will need a optical cable from your macbook to your sound system to have surround sound/dolby digital, and when you play the dvd it should automatically convert the output to a digital signal. I have this setup on my iMac and Macbook. I have the logitech Z680 (now Z-5500), and when I play a DVD, the screen on the controller says 'digital'.
The cable you'll need is a optical audio cable 3.5mm (for the macbook) to a toslink (square shaped with two corners tapered). You can buy cables which are toslink to toslink that come with adaptors for 3.5mm jacks.

Optical digital audio output/headphone out

Does anyone know if there is a way to connect stereo speakers directly (not through a receiver/amp)to the Optical digital audio output/headphone out on a imac? The new 20 inch imacs have a 24watt internal amp which would be plenty for the speakers that I want it to drive. Thanks

is there an attachment that i have to buy? do i just rip the tip of the cord off?
Yep, there are two "standard" optical-digital-audio connectors -- the original "square" one is still used in most larger audio/video components. The newer/smaller one, used mainly in portable gear, is exactly the same size as a mini headphone plug. Radio Shack carries adapters/converters and cables of both types (usually at outrageously high prices). For online vendors, try:

Great prices and a good rep for quality/service among to the HDTV-fanatics on avsforum.com.

Digital audio output problem

Hi All
I have just bought a Mac Mini intel duo 1.83hz and a Hitachi plasma TV 42inch model 42PD9700.
I have tried to link a toslink cable from the audio port on the mac mini to the TV . The TV has an 2 inputs for audio, a HDMI Audio jack and a RGB audio input.
I have tried both ports but get no sound from the speakers in the TV
The message in the system setting under the sound output tab shows
1 Digital output : Port - Built in Output
and settings for the selected device: The selected device has no putput controls
I have used the following adaptors with each side of the toshlink cable
http://www.maplin.co.uk/Module.aspx?ModuleNo=29296&TabID=1&C=KRS&U=MapAuto&doy=s earch&MenuName=Optical+Cable
What am I doing wrong guys?
thanks

HDMI can carry audio, but a DVI (from the Mac mini) to HDMI cable will not carry audio, just video. So, you'll have to select a different connection. I'm a little confused by your description of the other audio-in option on the TV as "RGB" since that means Red-Green-Blue which could be an SCART video port. This review says the TV has "stereo audio inputs" which, I would guess, are a pair of red & white RCA connectors (an analog connection). You might need a mini-jack to RCA type "Y" cable to go from the Mac mini's headphone port and into the two RCA jacks. Something similar to this:
http://www.pixmania.co.uk/uk/uk/187082/art/belkin/y-audio-cable-mini-jack.html
The Mac will switch to "digital out" if you plug in a digital optical audio cable with one of those adapters but that doesn't mean the TV is receiving that signal. A digital optical audio cable will not carry analog audio to an RCA jack.

Digital audio output - how?

I am new to Macs and the owner of a mini. I'm about to replace my stereo amp with an AV receiver so that I can use the mini as a media centre with a home theatre system. I want an AV receiver with a digital input as the mini has a combined analogue & digital output. My question is what type of digital lead to I need, are they standard and how do I tell the mini to provide a digital signal to the combined output socket rather than an analogue one? Or is it clever enough to work out what type of cable is attached?
Thanks in advance
Paul

I have my Mini connected to my A/v receiver using a digital TOSLINK to mini TOSLINK cable. It should have a mini jack connector on one end for the mini and a squareish connector on the other end for the receiver. The audio output jack on the Mac Mini can output both analog audio and digital. The digital input on my receiver uses a ADAT lightpipe connection on the other end, that looks like a square. These are standard cables and should not be that expensive. Here's an example of the type of cable:
http://www.amazon.com/6ft-Toslink-Mini-Cable/dp/B000FMXKC8
You will also need to make some setting adjustments in you sound control panel and in the DVD player to select the correct digital audio output format. Good luck.

Digital audio output question

Right now I have my Mini's audio output connected to my amp with a stereo mini jack. But as I understand it the audio out jack can also accept a digital (toslink) connector. There is surprisingly little documentation on exactly how this works or what cables are needed. Anyone care to enlighten me?
Thanx

Hi David,
Many people use the toslink optical audio cable.
There are different brands available.
I purchased several of these when they were on sale from Apple.

Note the tip adapter in the second and third photo.
This adapter lets you plug the cable into the audio out jack for the digital audio out portion.
