No audio from Optical Input

Hi there. I've recently bought a new TV which I use as my monitor but I also want to play the TV sound through my Mac (when i'm watching a tv programme, i want it to play through my mac). I've plugged the Optical cable into the line in and nothing is happening. I've checked all the settings and they all seem ok. I'm confused.
Any help would be greatly appreciated.
Thanks, Sam.

dear sam...
I think you're a little confused. Optical input would mean a dvd player/cd player
giving you an optical signal out. I haven't heard of any tv's that would do that, but I might be wrong. best bet would be to use a twin rca--> 3.5 mm jack cable
as the audio coming from your tv probably is analog
Hope this helps

Audigy 2 ZS Video Editor - recording audio from optical digital in - sound drops

Hi guys
I've had an audigy 2 zs video editor for a couple of months now and it's greatly improved my audio output from my computer.
But the other day I started trying to record vinyl onto my computer directly.
In the past I've always used my hifi cd recorder deck, then ripped the audio off the cd.
So I have my turntable connected to my amp, and I use my minidisc deck as a DAC, then record using an optical from my minidisc DAC, to the optical input on the front of the audigy.
So I fire up the creative smart recorder software and start messing with the levels.
I also use a free bit of software from
http://www.darkwood.demon.co.uk/PC/meter.html
called meterV which gives me a larger and more prominent read out of the level.
I then fine tune the output level on my DAC.
I have the stereo line out sockets on my audigy connected to an input on my hifi amplifier for listening to digital music etc.
So I start the vinyl and the sound starts coming through my DAC into my soundcard, the level readings start going, and the sound comes out of my hifi speakers.
My amp's switched to the audigy input - not the turntable
The problem is... every 30 seconds or so, the sound cuts out for 2-3 seconds and then resumes.
But the sound doesn't drop off on the level meters, or on the actual recording (recording 44.khz, 6bit wav file).
Only on the stereo line out of the audigy.
I ran the following test to see if the sound also cut out on the optical and coax outputs...
Whilst recording from the optical input, I've also tried recording to a minidisc portable from the optical out at the same time.
And the sound cuts out the same as when listening to the stereo line outs.
So the sound cuts off on the line out, the optical out, and also the coax out.
But this only happens when recording from the optical input.
When recording from the stereo line in - the sound doesn't cut out on any output!!!
The input selected in creative smart recorder is SPDIF.
This problem happens when smart recorder isn't even running - if I'm just listening to the line outs the sound cuts out.
But if I'm just playing back an MP3 or any sound, and there's nothing coming into the inputs, then playback is fine!!
So it's not a connection issue!
It doesn't seem to be triggered by sound frequencies - it seems to happen every 30-40 seconds no matter what is being recorded (it does the same thing when playing a CD so it's not just when using a turntable)
I've tried restarting the computer several times.
All the connections are properly seated.
I've had task manager loaded whilst this is happening to check CPU usage, and nothing - it just continues in a fairly straight line as normal. No spikes in CPU usage (I would have thought it unlikely that the video editor would be affected by such things anyway being an external box).
There is nothing else connected to USB - other than an internal memory card reader attached to a motherboard USB header.
And a wireless adaptor also connected to the motherboard - but the problem still happens when the wireless adaptor is disabled.
There's also nothing else connected to the USB ports on the Video Editor box.
Machine spec:
Shuttle SN4G2-v3
AMD Athlon XP 3000+
GB memory
80GB IDE HDD, 2 x external Lacie FireWire 250GB dri'ves
LG dual layer dvd/rw/ram
Win XP Pro SP2
I've not upgraded firmware or drivers - just used the installation from the CD.
What confuses me is why this only happens when recording from the optical input, and it affects all outputs but the recording and the level monitor show no trace of the temporary loss in sound!
So the audigy is receiving the sound, but it just drops off the outputs for some reason!
Any ideas?
I hope the above explanation is clear.
Thanks

Sorry for not replying - have been away for the past few days.
Ok, so I go to Creative Device Control, and on the PCI/USB tab I've changed the sampling rate to 48khz.
It was previously at 44.kHz
The bit depth is still at 6bit
Now the problem seems to be solved.
The problem was only with the output from the device. And now there are no skips!!
Excellent!
Why has that solved it though?
I've read on other forums (head-fi) that the audigy cards do not run at 44.kHz nati'vely so the sound has to be downsampled.
Is that skipping an artefact of that downsampling process?
Will having that set at 48kHz, but recording to a 44.kHz 6bit wav file theoretically reduce the quality of the recording - compared to having it set at 44.kHz and recording a wav at 44.kHz?
On the SPDIF tab the input sample rate is shown as 44.kHz - as that's what is output by the DAC in my minidisc deck.
But when I changed the sampling rate on the PCI/USB tab, the SPDIF output sampling rate also changed to 48kHz.
This means if I wanted to record from the optical output, whilst also recording to the computer, and that device only supported 44.kHz - I can't do that?
You listed some main reasons to the truth, why Creative SB cards are not very popular on serious use (DAW). I.e. need for resampling. X-Fi's in creation mode are (least said to be) the only ones not resample everything.
There is a setting for "Bit-Accurate-Recording" (digital modes only) --> have you tried if that works on your recordings?

Pass audio from optical IN to analog out

Hi Guys, I'm new here, I'm barely get my SB Zx and I'm wondering if I can do this:
If is to much problem or is not posible, I'm only need to find a 10ft toslink cable, jeje, is not big deal, but if I can do it on the way of the drawing, is going to be a cleaner installation, Thank you!

CarnageHimura,
If you intend to have the compressed bitstream (Dolby Digital or DTS) audio pass through to the sound card (Sound Blaster Zx) for decoding, and then output the decoded audio content to your connected speakers system (I believe this is the Logitech Z906) via analog connection, then the answer is 'No'.
Other than the audio source itself (the content playing on your XBox 360), wouldn't it be easier to connect directly from your XBox 360 to your speakers instead?
Regards,
Colin-CL

Live! 24bit External - no audio from optical

I have a Li've! 24-bit External card. I have 2ch analogue speakers plugged in the analogue port and they work fine.
I also have an optical cable from the SPDIF Optical Out port on the Li've! going to a Sony AV digital receiver that has a surround system connected. But I'm not getting anything at all at the receiver.
I've tested all the optical cable and the receiver by connecting a DVD player at the Li've! end and it plays fine through the cable-receiver-speakers.
But nothing comes out when I plug the optical cable into the Li've!. I have had this working in past, about 2months ago, but just tried today again an nothing, zip, nada.
I've downloaded and updated the latest drivers update. The Li've! box came new less than 6mnths ago with this new computer system.
I work in the IT field but this has me stumped. I'm starting to think something cactus has gone wrong with the SPDIF side of the Li've! box.
Help.

dnwallace,
Did you happen to change the sampling rate to 96khz(maybe something that the receiver cannot handle). Try changing the sampling rate around to 48khz.

Sampling is at 48khz.

No audio from Optical out!

I'm using an ATV2 with HDMI going to my TV and an Optical cable going to my Pioneer receiver. I am not able to get any audio signal through the Optical out of the ATV. Dolby digital is set to "on" in the ATV and my receiver is set to accept a digital signal. I have seen some other message boards discussing this as being a common problem that may be an apple related issue. I'm just curious if anyone else has had a similar experience and figured out a way to work around it.
Thanks in advance!

I wouldn't say similar issues are reported commonly, but there are enough of them on a reasonably regular basis, to be considered more than a handful. The majority of such reports appear to be resolved by making settings adjustments, on either the Apple TV or the receiver.
I'm unlikely to be familiar with your receiver, but you might want to try with 'Dolby Digital' set to off.

Digital Audio Optical Input S/PDIF on Mac Mini 10.9.2

For years prior, with my MMP 15", etc. and since the fall the Mac Mini (fall '13), the setup worked flawlessly ... until recently -- since around the time updating to 10.9.2 I have had intermittant issues with the digital I/O with my Apogee Rosetta 200 until it stopped all together last week.
I have replaced or swapped out the cables first off, to no improvement -- I called Apogee and we were able to prove the input to Apogee with an Eventide Esclipse's S/PDIF output.
I called Apple and the tech and I rebooted in safemode and saw the Audio Devices pane of Audio Midi Setup and Sound neither showed the digital input/output as being active. I sent the unit in and the logic board was replaced in view of the circumstances.
I just setup the repaired unit and now the S/PDIF out (from the Mini to the Rosetta) works -- the Sound pane shows that shows the functioning digital input however, and conspicuosly, the Audio/Midi does not (and used to).
Further, the S/PDIF in (from the Apogee to the Mac) is neither functioning nor the two panes, Audio devices and Sound, register the digial input.
Is there an issue with 10.9.2 or is it possible the one of the 1/8" analog/light pipe inputs of the Mac Mini is also not working and not determined/checked duri -- other ideas?
I have a backgorund as a Mac tech and a member of Apple Solutions Expert since back in the 90's ...

The optical digital audio input is a good way to get basic digital audio data into the Mac - assuming you have the audio in that format. Most vinyl digitizing folks do not.
The most common hardware configuration is to use your old vinyl turntable, connected to the proper phono input of a stereo (most modern stereos do not have this and you have to buy an outboard phono preamp). Then the recording (tape) output of the stereo goes to an audio interface that connects to the Mac with Firewire or USB, and not using the Mac optical input at all. There are dozens of famous makers of interfaces from a hundred dollars to thousands. For the casual user, I'd say $250 is a nice spot. You can get a stereo interface that takes analog input from your stereo, digitizes it, and send it to the Mac. It will also accept microphones, should you want. You'll need software to record and edit the audio (Audacity is free and works) and you can use iTunes to make CDs (although cumbersome).
There are interfaces that do have optical outputs that you could connect to the Mac. But since optical interfaces are rare on computers, and have many limitations, this isn't so common.
There are many tutorials on the net about digitizing LPs on computers.

Airport Express connected to optical input on receiver, but no audio

I have a Rotel RSX-1055 receiver. I recently bought a toslink cable to connect my Apple Airport Express to the optical input. The receiver seems to be getting a signal - 44.1 khz scrolls across the display when I play music - but I'm getting no audio.
I'm streaming VBR MP3 files converted from CDs using LAME on a high quality setting. I can't seem to find any reason why this isn't working.
Any advice would be greatly appreciated.

Hello rjpwp001. Welcome to the Apple Discussions!
I suggest trying the following:
o Connect a pair of stereo headphones to the AX's audio port. Does the audio stream play thru the headphones properly? If it does, this should verify the analog audio circuitry is functioning.
o Try a different audio source, like iTunes. While connected to the receiver with the TOSlink cable, try different audio selections from iTunes. Are you getting sound at the receiver now?
o Try a different TOSlink cable. How about now?

Digital Audio Optical Input S/PDIF cable recommendation

I have a 2010 iMac. I am beginning to research a project for my mom that involves converting old recordings a group my dad was in years ago to digital from vinyl. I have a couple of input options available but I'm seeing reference to optical input on the iMacs. It appears that this would give me the best audio quality. So, my question is this: To go from a pre-amp output, what cables, converters, et cetera would I need to in order to make use of the optical input for audio? I have looked through the forums and see some mention of the subject, but nothing that seems directly to address the specifics of this.
Thank you.

Alarming news on optical audio from STB!

I have a Verizon stb QIP 7232-2, a Sony (Bravia) HDTV, a Sony BlueRay player, an AM/FM receiver, a CD player, and an AudioSource soundbar with inputs for oprical audio, mini-plug audio, and stereo audio. The configuration is as follows:
STB connected to HDTV via HDMI cable, BlueRay connected to TV via HDMI cable, BlueRay connected to AudioSource soundbar via optical audio cable (works well), STB connected to AudioSource soundbar via optical audio cable and NO sound is generated.
After 3 days of searching online, forums, Verizon support, etc., I initiated a support chat with Verizon today. The exchange is below, but the astonishing part of it is that I was told that ALL VERIZON STBs are disabled and cannot be enabled! My question about why Verizon would choose to limit functionality and ultimately the user experience of excellent sound was never answered. Also, if all optical audio ports are disabled, why would Verizon hide this from users and actually tout the various connection options? For what reason would I be told that this port cannot be enabled? My research reveals that COMCAST does not have this issue. Never mind that the manual touts the various connectivity options and displays wiring diagrams that include the Optical audio port.

John(19:40:11): Ms. Rogers, may I know were you able to access the optical audio port earlier?
Carol(19:43:57): access? it's on the back of the STB and noted as a feature! I have not tried to use it prior to this week. I purchased the soundbar to enhance our TV/Blueray experience. I purchased an optical toslink cable (actually 3) and attempted to connect everything. THere is a light in the cable when connected to the stb, but no audio. The cable and the soundbar both work successfully with the blueray player AND an old Technics stereo am/fm receiver
Carol(19:44:40): and my iPod via a miniplug
John(19:45:11): Ideally the Optical toslink port is disabled for all the boxes.
Carol(19:45:23): why?
John(19:45:59): Ms. Rogers, only the coaxial, HDMI, Component and composite ports are enabled on the set top box.
Carol(19:46:12): again, why?
Carol(19:46:22): can it be enabled?
John(19:46:52): Unfortunately, we do not have the option to enable them.
Carol(19:47:18): and why wouldn't you tell your customers that this port is disabled BEFORE one purchases a home theater or soundbar.
Carol(19:47:46): that's crazy - you can't enable. AGAIN, WHY?
Carol(19:48:24): I understand from days of research that COMCAST does not have this problem.
Carol(19:48:35): Really - this is how you serve your customers?
John(19:49:11): Carol, we would have provided the answer for why it is disabled.
John(19:49:26): However, on the QI{ 7232 box we have the e Sata port only for outward option.
John(19:49:31): *QIP
Carol(19:49:56): what does that mean/
John(19:51:41): We can use the E-Sata drive with the 7232 box to save recordings.
Carol(19:52:34): i don't know what an e-sata drive is or how it conflicts with an optical output. That doesn't make sense to me.
John(19:53:29): Carol, I understand your concern.
Carol(19:53:42): Why would Verizon want to limit its customers' ability to enhance the user experience and benefit from technology?
John(19:53:47): However, we can only forward your concern to our higher level network team to work on the Optical port enable option.
Carol(19:55:49): I have been in customer service and I understand that "I understand your concern" is the polite way to say "I can't wait to rid myself of this whiny customer!" I also understand that none of this is your fault and you have no power to change it - so believe me, it's not you. YES PLEASE FORWARD MY CONCERNS TO SOMEONE WHO CAN ANSWER MY ENDLESS "WHY?"

Does your soundbar support Dolby Digital or PCM. You may have to change settings that are in the hidden menu if it doesn't support both. Hidden menu, while on hit off, ok ok (suggest doing it at box)

Stream audio from sound card input thru network

Good Day:
I have an application where I need to access instruments at a remote location. Command/Control of the instruments is not a problem, but I also need to stream the audio present at the remote system's sound card thru the network connection. Any suggestions on how to accomplish this via LabWindows?
Thanks in advance for any replies.
-Ed

Hi Ed,
First, I was wondering, how do you get the audio from the sound card? Is it from a LabWindows program? I've never done that. Second, I was wondering how do you play the audio on the remote machine? Is that through a LabWindows program? I've never done that either.
But I was wondering if just a remote PC app would do the job. Like admins use to take over your PC from there desk and fix problems. I assume they have these that send the audio thru the net as well as the screen. Then on the radio's PC you just need a LabWindows program to control the radio and some other app to play sound from the sound card input to the local speaker. Then the remote PC app would magically transfer the screen and audio from the radio PC to the remote PC.
Otherwise, I can just say that to stream the audio thru the net, after the Radio's PC gets it off the sound card somehow, I would just set up two TCP servers on the remote PC, one for audio and one for the commands/control. When the remote PC client connects to the audio server the audio server would just start sending audio data to the client. The client would receive the data and put it in a big buffer to handle network speed variation. Let the buffer fill up to like a second or more worth of data before having anothe function/thread read the buffer data and give the data to the client PC's sound card. Big problem is that the client PC's sound card will alway's consume the data at a slightly different speed than the servers sound card produces it. Different clocks running at slightly different frequencies. So the client function that reads the audio buffer to give it to the sound card must play games. If the buffer is shrinking over time then it has to create extra samples to give to the sound card, just duplicating a sample every 100 samples or whatever. If the buffer is growing over time then it throws away a sample every 100 sample or whatever. So it's kind of a challenge to manage the buffer with the variable speed of the net transfering data and the two different rates of producing and consuming the audio data.
LabWindows has the TCP server create and client create functions so that's pretty easy. The harder part is that you probibly want to set the Radio's PC to a fixed IP address so that you can connect to it without worrying about domain names and such. Then the two TCP ports that the LabWindows uses for command and audio might need to be setup in all the routers to let you establish a connection. Your IT guy's can answer that.
PS. you can play around with this suff on one PC by using the RegisterTCPServerEx function and setting the local host address to "localhost", or "127.0.0.1" on one LabWindows project and using the corresponding ConnectToTCpServerEx with "NULL" as the server host name on another LabWindows project. This creates a virtual TCP connection on the same machine. This does not duplicate the different audio clock issue I talked about above.

How do I get signal from Digital Optical input (Extigy) to the Creative PlayCent

How can I rip MP3's from the Digital Optical input on the Extigy? The PlayCenter does not seem to have any interest in the Extigy/USB as an input source. Thank you for your help!!?

Since you are talking about variables, I suppose that you are using CP4, right?
There is a fine tutorial in de CP4-help, chapter 'Variables and advanced actions', 'Tutorial on scripting' which explains more elaborately what I will try here:
Create a user variable, p.e. named 'vName' (Project, Actions, sheet Variables)
Ask the user to enter his name in a Text Entry Box; in the properties of this TEB, sheet Advanced you indicate that this name should be put in your variable 'vName'
Wherever you want to show this name, create a Text Caption and insert your variable by the button 'Insert variable'; this button is present in the properties window and also in the formatting toolbar if you are editing in place (look for X and and arrow); the variable in the text caption will show as '$$vName$$' and in the published SWF you will see the username.
Hope this could help you, but please check the tutorial.

Optical Input on Creative Labs Sound Blaster X-Fi Xtreme Audio PCI-E with Logitech z-5

So i plugged in my Optical cord into my new sound card the Creative Labs Sound Blaster X-Fi Xtreme Audio PCI-E and it worked only in the Front right, Front left, Front centre, and the subwoofer. Now i hear i need a external decoder... but then again that my sound card should decode it as well... the place i bought my card recemended a optical cord for my card?with the?speakers i have?(the?Logitech Z-5500) How much are decoders? What should i do next? Creative seams to have limited support especialy on optical inputs.

I must have answered something like that in another thread sometime ago, but here goes:
A single SPDIF connection, optical or coaxial, will only transfer stereo in analog form; no rear or centre channels!
There are two ways you can get all speakers playing via such a connection:
() Get your speakers to upmix the audio source to play on all fi've of them
(2) Output a Dolby Digital (AC3) or DTS signal. These contain the multichannel information encoded in the stereo signal. A suitable decoder (such as the one contained in the Z-5500) will be able to analyze the signal. Unfortunately, this is something you can mostly find in movies.
So, to sum it up, no natural everyday multichannel sound over one SPDIF (e.g. no EAX, directsound3d etc.)

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.

I recently purchased an Onkyo stereo receiver with a wireless USB adapter, UWF-1, and want to stream audio from my MacBook Pro through my stereo system. The receiver tells me it is connected to my wireless LAN, but I cannot get music to play?

New to the community here, thanks for your patience. I recently purchased an Onkyo TX-8050 Network Stereo Receiver with the UWF-1 USB adapter with the intent to stream audio from my MacBook Pro to the stereo. I have gone through the setup instructions for the adapter and the receiver gives me a message saying that it is connected to the password protected network, but that is as far as I can get.
I have gone into iTunes and clicked on the "Open Stream" option, but I just get a pop up box labeled "URL" that is empty. I have Home Sharing turned on and File Sharing turned on, but I am not seeing the receiver in my Finder window or as a iTunes device.
I would appreciate any and all advice and assistance.
Thanks so much.

So I have been searching the iStore for Airplay and I find lots of information about what it is, but nothing about how much it costs, how/where to buy it, etc.?
Fortunately, AirPlay does not cost anything as it is a streaming protocol used by Apple. Currently, the AirPort Express and Apple TV are AirPlay-ready. A number of other companies, like JBL, iHome, Denon and Klipsch are also rumored to be working on AirPlay versions of their products.
Your other option would be to get an AirPort Express and connect it to your Onkyo analog or optical digital audio input and stream from iTunes that way. I currently do this with my 10+ year old Harmon Kardon HT receiver.

No audio from Optical Input
