Optical Audio setup?

Does anyone know if you need to set up the optical audio on the 6416 stb in order for it to work?
In addition to the HDMI handshake issue now I cannot use my Yamaha home theatre because when I converted to component I had to use the (2) sound outputs on the stb.
I am also checking with Yamaha because when I connect the one end of the optical cennector to the Verizon stb the other connection lights up, but when connected to the receiver the other connection is not illuminated. I don't know if that has any bearing.......................
All I do know is that these Motorola STB's (especially the DVR) are garbage and need to be replaced with something that works.
I appreciate any imput.
Solved!

This may or may not work for you, but my old Sony receiver assigns the optical audio input as a DVD input source only. So I have to switch to DVD on my receiver in order to get sound from my STB (have the optical going directly from the STB to the Sony receiver). Is it possible your receiver may assign optical audio to a different source name. May be worth a try switching to see what happens. If that's not it, then unfortunately I have no idea with my limited technical skills. Thought it might be worth a try.

ATV2 Optical Audio Setup

I'm considering getting a new home theater receiver mainly for the purpose of being able to use the Apple TV 2 optical audio, but I want to make sure that it will actually do what I want. Does the optical audio make it so that you don't need the HDMI at all when using it? I want to just be able to use the iPhone remote (and my computer's iTunes) to select music and send it to the AppleTV, but not need my TV on. Just have the audio go to the home theater system. Thanks.

Hi,
I don't have a reversal in any mode (DTS, 5.1, Dolby stereo, plain stereo-from itunes library). Maybe try a reset and check your cabling and Handbrake settings. BTW I encode in 2 steps: Ripit to copy the DVD and remove copyguard since it is better at this than Handbrake, then I encode to m4v with handbrake and just pass through the 5.1, finally use Subler (free) to add metadata.
ATV2 is HDMI to receiver and out to speakers with wires and video via HDMI to TV

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

Optical Audio Problems

Hi guys,
I'm having a little trouble getting my Mac mini to play audio via optical out through my Sony HT-IS100 home theatre system.
Below is my correspondence with Sony UK so far listing the problem and current connections. Their reply indicates that the problem is the way the sound is output from the mini. Does anybody know what the default output audio type is via optical?
It is worth noting the problem occurs through iTunes, front row, safari, quick time etc.
I also tried using my MacBook Pro and the same problem occurred. Does anyone have any ideas, or are Macs just not compatible with my setup via optical audio?
Thanks in advance,
Jib
Here is the link to the manual referenced by Sony http://www.superfi.co.uk/extras/Sony/sonyhtis100manual.pdf
=================================================
Hi there,
I'm having trouble getting the sound from my MacMini to output through my recently purchased HT-IS100 system.
The MacMini is being connected via a TOS optical cable for the sound and a HDMI cable for the picture to the SAT inputs on the HT-IS100.
The picture is working fine, as mentioned the audio is not. The HT-IS100 is working fine for all other inputs.
The optical cable has been checked and is working when used for other components, as has the optical out port on the MacMini.
When the HT-IS100 is turned on from standby, the OPT and PCM light are on and I get audio for about a second before '2.0 channel' is displayed and the audio disappears.
Have looked through all trouble shooting and online guides and nothing to help me with it. I also tried calling my local sony centre with no luck there either. All components are working so am assuming it is just a setting that needs to be changed.
Can you please advise on how to fix the problem.
Many thanks.
Dear Mr ------
Thank you for your recent e-mail received on 11/03/2010 03.20 PM.
I am pleased to read that you are the owner of a HT-IS100, but sorry to learn of the issue you are experiencing.
Having investigated your enquiry, it appears that your MacMini is outputting a sound signal that is not supported by the HT-IS100. For example, the maximum PCM input for the Home Theatre System is 96khz. The Home Theatre System will automatically select the best decoding mode for the sound that is being received, so it would not be a setting on the Theatre System that needs to be changed. As this is the case, I would suggest that you view the supported sound specifications in the instruction manual and ensure that your MacMini is outputting a supported signal. Please refer to page 76 of the manual for the specifications.
I hope this information is of some assistance. Thank you for your enquiry.
Yours sincerely

Just to update this in case anyone can still help, or if anyone searches a similar topic.
Latest reply from Sony
Dear Mr.....
Thank you for your reply.
If the SAT optical port works when connected to another product, this still indicates that it is an issue somewhere in the Mac settings causing the problem. It is possible that interference in the HDMI cable is causing the Home Theatre System to listen to sound coming from the HDMI port rather than the optical port. I would suggest that you try connecting the Mac just with optical and no HDMI, to see if the issue still occurs. If the problem is resolved, I would recommend that you use another HDMI cable.
If the same issue occurs, this indicates that is a Mac setting somewhere causing the sound output to be incompatible. In this case, I would recommend that you contact Mac for assistance.
I hope this information is of some assistance. Thank you for your enquiry.

So, with HDMI unplugged the audio works through the optical input to the HT-IS100 amp. With a HDMI (all cables working that I tried) plugged in, the picture comes through but no audio for that channel.
So there must be something outputting through the HDMI from the mac mini to make the amp try to take the audio from there instead of the optical. Tried all TV output settings on the mac and same problem across the board. Does anyone know if there is anything else I can try, or is it time to just accept this combo does not work as it should?
Since the last post, I discovered that the sliders in the midi setup should be grey due to control being shifted to the amp, so all OK there.
Thanks in advance if anyone has any help.

Optical Audio Is Not Working with Onkyo Receiver TX-SR501

Hello,
I can't seem to make the optical audio from Apple TV work with my Onkyo Receiver TX-SR501. The Onkyo has 2 optical audio lines in in the back. When I hit the "digital input" button on the front of receiver, I can select from OPT1, OPT2, or COAX. I currently have the optical audio line going into OPT2, but if I select OPT2, I hear no sound. Any suggestions?
Thanks,
Holly

I have the exact same receiver (Onkyo TX SR-501) and tgibbs is correct...you must (during a setup process) link each function (DVD, Video 1, Video 2, Video 3, CD, etc.) with its audio source. The Optical cable doesn't connect to a "function" in the back, it connects to an "input". The receiver gives you the freedom to use different inputs with different functions. It's your job, durng the "setup" to map each of these inputs to each function...that way the receiver knows where to go looking for the audio that you are feeding into it for each function you choose. The owners manual has a pretty clear setup process outlined in it.
Not clear to me that you understood this, so forgive me if I am explaining what is already clear to you.

Cant get audio out from iPad airplay on optical audio

I have an apple tv in school for streaming video of drama classes to big screen. Apple tv is plugged into HDMI on projector and i airplay the videos from iPad. My issue is getting sound - the projector has no speaker in it so no sound is currently playing. I purchased an optical audio to 3.5mm jack lead to go from the rear of the apple tv to a set of speakers on my desk. Nothing seems to be happening - will this setup just not work or is there a way for my classes to hear the soound as i airplay it?
Any help GREATLY appreaciated!
Thanks

Where did you get the lead - it would ordinarily require a D/A converter between the optical connector and the 3.5mm jack...

Optical audio out to receiver

Hello, I have a powermac g5 hooked up to a vsx-1014tx Pioneer receiver via digital optical audio. When I'm using dvd player and select "system sound output" in Dvd Player's preferences I get audio through the digital optical hookup and sound out of the speakers, but the receiver's display doesn't switch to DIGITAL (it displays whatever sound processor I select on the receiver such as dolby prologic II) i.e. the computer outputs 2 channel digital audio. When I switch to "digital out - built in audio" in Dvd Player's preferences, there is no sound output while watching a movie. The receiver flickers between DIGITAL and DD Prologic II. Is there anything that you know of that will allow me to get 5.1 Dolby Digital put out through the G5's optical audio out? (settings, audio codec, ect.)
P.S. I have software updated and in system preferences/sound I have digital out selected
Thanks for your help
Daron

Not sure if it will help resolve your issue, but you can make more detailed adjustments to the audio output using +Audio MIDI Setup+ utility, which is in your Utilities folder.

Optical audio but Analogue output

Hi, I connected my AppleTV to my Bose audio system ONLY with optical audio cable.
I figured out that sounds comes out with a movie in DD and ALSO with other sources (like youtube videos).
The Audio & Video settings on ATV is setup to ON regarding DD.
Question: I thought that with that configuration I could hear only DD audio stream. Is a BOSE features or ATV output audio through optical always regardless its source format ?
Thanks, Roberto.

Oh yes, this is the reply I was looking for, so in this case I could avoid using the analogue output (RCA) on ATV ? In the case I'm going to use it anyway which will be the channel used by ATV for outputting audio ?
Question: if I have a movie with two audio tracks (the first one stereo and the the second one in DD) and connect the ATV to my Bose audio system with optical audio cable and my ATV is setup with Dolby Digital on which will be the audio stream passed to my Bose audio system ?
Thanks, Roberto.

Optical Audio - Analog Audio Adapter?

I have been thinking for a while about buying an Apple TV.
One of the main reasons I want an Apple TV is for streaming music through the Apple TV into my stereo system WITHOUT having the TV turned on.
So this means I need to use the Optical Audio port to go straight into the stereo.
I have a Kenwood XD-551 stereo system which is reasonably old and only has Analog Audio input. That means I can't connect an Apple TV to the stereo using an optical audio cable. Is there an adapter I can buy that connects Optical Audio to Analog Audio?
I know I can stream music to the speakers through an AirPort Express (I have a 3.5mm to Analog cable), but I want an Apple TV also to stream HD Movies and TV Shows from iTunes, as well as AirPlay Mirroring from my iPod Touch.
My current set up:
TV --- 3.5mm jack to Analog Audio Input --- Stereo
My intended setup:
Apple TV --- HDMI --- TV
Apple TV --- Optical Audio to Analog Audio Input --- Stereo
I REALLY NEED A SOLUTION TO THIS OR ELSE I MAY NOT END UP BUYING AN APPLE TV

I am also looking for a exactly a similar setup.
streaming music through the Apple TV into my stereo system WITHOUT having the TV turned on
@alexei Ok, so this solution works with you. just to understand the setup,
you connected the apple tv's 'optical digital-audio port' to a DAC using which kind of cable ? links from amazon or other websites will be very useful.
Output from this DAC, you connected to the speaker via 3.5mm jack, correct? again a cable name (both ends) will be extreemly helpful.
With this when you airplayed music on 'apple tv' via itunes just the audio played on your speaker, correct? assuming your TV turned off during the music play.
And when you airplayed video/movies on 'apple tv' it automatically played on your TV.
Just wanted to know, you see only one airplay configured on your iphone/ipad correct ?
If this exact setup works with you..then bingo..I can go ahead buy all those stuff. If you have a different set-up with which you play music and video sepeartely using apple tv then please do share..
Your answers to these quesions will help me to decide if I need to buy Apple TV for music(which is equally important) and watching movies. And the invetsment dosent stop there..therz DAC and cables.
Thanks!
PS: I know I can stream music to the speakers through an AirPort Express, but want to go for apple tv.

Optical audio vs HDMI

Hi all
I have the Apple TV and recently got a 5.1 Surround system set up. I also needed an optical audio cable to link my TV to the Subwoofer. Then I discovered the Apple TV has optical audio.
Why would the Apple TV need optical audio when you have HDMI?
Does using the optical audio cable activate all surround sound speakers?
(Since when using Apple TV, only my front speakers work and not the rear speakers.)
Thanks !

Thanks for that. I did some searching, but couldn't find the posts on the subject. I didn't know there was a problem with this setup, so I didn't know to look for that. I think my best bet, at least for now, is to try connecting the HDMI to the TV only. I found that I do have an optical out on the TV which I can send to the receiver's optical input. I didn't realize I had this option. I'm just not 100% sure it will work yet. I have everything I need to do it, I just have to take the time to set it up. Thanks for the info.

Cannot get optical audio in working

Hi all,
I have a new MacBook Pro (latest 2010 version) which I specifically bought for audio recording/editing purposes.
However, I cannot get it to work at all, recording is useless except for a normal 3.5mm stereo-in jack. I cannot get the MacBook Pro to record either through optical audio in (my preferred solution) or through my EMU0404 USB soundcard. I basically have a £1,000 brick with a light in the shape of an Apple on the outside and, as it's my first Apple computer, I'm struggling to fix the issue (and struggling to avoid calling it all kinds of names on this forum!)
Any help would be appreciated. I've tried changing the settings in the MIDI setup under utilities, but it's just not recognising the input. Whenever I plug the optical cable in, the Sound preferences screen automatically defaults it to 'Digital Out' and won't allow me to select anything other than the onboard mic as the input source.

Do you by any chance have the 13 inch MacBook Pro? This has only one 3.5mm jack, switchable between input and output; but there is no optical input, only output. Inserting an optical cable into this jack will cause the socket to default to output only (since it knows you want optical and there is no optical input), leaving the internal mic as the only possible input.
The EMU soundcard claims to use CoreAudio and so should work without drivers and appear as an option in Sound>input. Are you trying to use an unsupported sampling rate? - their tech spacs page says 'Macintosh analog operation up to 96kHz and digital operation up to 48kHz only at this time.' If you still can't get any sense out of it, it would be worth approaching the manufacturer.

Using MacBook Pro as Digital Optical Audio bridge...

I have an idea for my MacBook Pro, but I'd like to know if it's feasible before I go and buy what I'd need to test my plan:
I have an Xbox 360 with digital optical audio out (TOSlink), and I have a MacBook Pro with digital optical audio in (through the 3.5mm minijack on the side. So far I'm A-OK.
Now, I'd like to know if I can have the Xbox's output go into the MacBook Pro's input, and route that audio signal through the MacBook Pro to either (a) the stereo output of the MacBook Pro, or (b) (preferred) my 5.1 decoder on my Griffin FireWave.
Every time I use the Xbox, I have to unplug the audio from my speakers to the Griffin FireWave, and that's a pain because the wires are all behind my desk. If I could route the audio through my MacBook Pro, then everything would be perfect. Is this possible?
And if this isn't possible, can I use an old iMic adapter I have laying around to route the audio through the MBP?
Thanks for your help!

I found a program called LineIn that allows 'software audio pass through in to out,' but I don't think this will pass the 5.1 channel audio through to my FireWire-connected Griffin Firewave.
Does anyone know of any way this can be done? Do you think the Audio/MIDI Setup Utility application can be of any use with this? Or is there a way to pass the digital signal straight through to the Griffin?

Mac Mini (Mid 2010) Optical Audio Annoyance / Issue

Hi,
I just purchased a new Mac Mini a few days ago and got it up and running with HDMI to my TV and optical audio to my AVR. I have bitstream passthrough working in DVD player and VLC / Quicktime with Perian installed. Happy camper on that end.
My issue lies that I am unable to change my speaker configuration from 2ch stereo in Audio MIDI Setup. This means that I can not use my 7.1 AVR to monitor 8 channels of audio out of the pro apps I'm trying to use! (Final Cut/Soundtrack)
I even wen as far as to take the HDMI out of the mix thinking that it was affecting the amount of audio channels available to me and switched to using a MDP->DVI adaptor with a DVI->HDMI cable so that audio is not passed. No dice.
Is there some kind of magic mojo that is needed to get Audio MIDI Setup to allow me to select more than 2 channels when using an optical connection? I really would like to use my pro apps and monitor my mixes as well as watch
Look forward to hearing from the Apple guru's here! Thanks.

As far as I'm aware any form of DD or DTS whether it be 5.1, 6.1, 7.1 or indeed 7.2 is discrete by nature.
They contain discrete sound channels, but all are contained within one bitstream. They are encapsulated, if you will.
To my understanding, multi-channel PCM is not encapsulated in the same manner.

Yes DisplayPort can provide audio. But you have to either be using an displayport-to-displayport connection, or using an appropriate adapter.
But a typical MDP to DVI adapter is not going to pass audio.
Mr.C UK wrote:
...DVI does not pass through sound...
This is correct insofar as the fact that the DVI spec does not include audio. And as you said, a typical MDP adapter does not pass audio.
But just so you know, the DVI interface can actually carry audio, if it is present. When I had my 2010 Mini's HDMI port connected to my DVI Detective (via HDMI-DVI adapter) and then the DVI detective was connected to my HDMI reciever (via DVI-HDMI cable), I was receiving the HDMI audio stream at the receiver.

Apple TV optical Audio stops working when connected to switch

Hi everyone,
I'm installing a brand new Apple TV in the following setup:
Apple TV (is up to date)
- HDMI to HD Beamer
- Optical Audio to Sonos Playbar (Works instantly)
- Optical audio through switch to Sonos Playbar which doesn't work
UPC Box
- HDMI to HD Beamer
- Optical audio to switch to Sonos Playbar (Works instantly)
I've tested all the ports on the switch and cables already and they all work. So the weird thing is when I connect the optical from Sonos directly to the Apple TV it works perfect. But when I use the switch it doesn't work. I see a light in the switch so there should be signal...
The switch I'm using is:
http://www.allekabels.nl/optische-kabels/5/1424/optische-schakelaar.html
I've read older questions and tried different audio settings but nothing seems to work. Can anybody help me?

so i solved my own problem haha here's what i did incase anyone has the same issue
go to system preferences > sound > output > click on headphones then turn the volume up from mute
for some reason every time i reconnect to the uni wifi it goes back to mute. not the regular volume only the one through that pathway.

Lion Optical Audio Problem

It's an outrage truly. Can't believe the hours I've wasted troubleshooting this problem...and it goes back at least 3 upgrades ago that my optical audio started to fail / stop working once sending DTS 5.1 via toslink. Going back to play audio in iTunes, or anywhere, would fail / no audio. Somehow the audio driver would lock and corrupt the system. No amount of audiomidi setup configuration would do a thing. Reboot was the only fix. 120 of them later....I tried a soundblaster x-fi usb bypassing the imac sound completely. The box worked perfectly! Except, for the exact same problem switching between the 2. It became apparent that the os was screwed...absolutely no doubt.
I gave up and was ready to build my own dang system...sell the beautiful but broken imac to someone.
Low-and-behold, I see this small line item in the list of 10.7.1 fixes tonight - mix of rage, insult, disbelief - how on earth did perfectly working audio get broken and downgraded?
How do we learn more about this product we've purchased that is getting broken by someone, no "sorry 'bout that?", or, "by the way, to our loyal customers going through **** trying to fix their broken audio, we know, we're working on it..in the meantime, here's $25 worth of stupid app store junk, including the sickingly popular birds game for free!"
Certainly this is likely answered in the incredibly boring license agreement I never read. "We are not responsible for hours wasted with broken software."
Done.
Frank

Yes, 10.7.1 appears to work (knock on particle board). I am now able to play a video file with DTS audio, the receiver automatically switches to DTS..Then, I can quit Movist, open iTunes and play 2 channel audio..The receiver automatically switches. Before, I would try to play regular audio and no sound. It seems I am able to switch back and forth without corrupting the system for a reboot.
To be even more clear about my experience; Snow Leopard worked fine for this 'normal' functionality of switching audio from 5.1 to 2ch. It was only during a subsequent update of Snow Leopard that audio broke. It is now, nearly weeks after Lion release, that this has been addressed (a second time - the first osx update to attempt to fix optical audio problems did NOT work).
Were you able to get 5.1 before and now cannot? What app are you using? Do you have a 5.1 receiver?
Frank
