Understanding a Loss of audio output

I have switched on my G5 after it being switched off for a week.
I have no audio from my firewire attached speakers or from the G5 speaker or via the iTunes/Airport express hifi connection. There is however sound when headphones are plugged in.
I have tried rebooting, repairing permissions, disconnecting firewire etc but to no avail.
When I check the sound preferences then the firewire speakers (La Cie) are listed and when I connect and disconnect them then they appear and reappear on the list as expected.
I'm just looking for some guidance on diagnosing what the problem is. Any suggestions would be most welcome.

Thanks for the advice. I had followed most of it through prior to your messages. But I repeated things again a couple of times and am finding that part of the problem seems to be with the firewire speakers. They've been a flawless addition to my set up for some years and they don't appear to be playing sound although as I mentioned earlier they are recognised by the sound preferences as well as the System information.
In my sound preferences also the main audio out speaker in the G5 does not play sound at all. I've resolved the airport issue so can at least get the iTunes going but the system audio is not coming through the default speaker or the LaCie firewire speakers. Its headphones or Airport.
I also did have a look at the audio midi setup and neither system audio or Lacie speakers generate sound. Any further thoughts are welcomed.

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

I lost audio output except for USB headset any Ideas?

Has anyone experienced the loss of audio output except for the USB port? If so what might I try to fix the problem?

Hello,
Ever had anything plugged into the sound out port, sometimes the jack doesn't close properly?
Have you done a PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

Audio Output from Mac Mini 2010

Hello -
I purchased a mac mini 2010 this weekend for use as a home theater PC. I've got it connected to an Onkyo tx-sr604 a/v receiver via HDMI. I then pass the HDMI signal from the Onkyo to my hdtv, so I think it just passes through. For audio, I use a surround sound system. And, in case it matters, I have a second tv connected via the DVI output on the mini.
The Onkyo indicates that the audio input signal on the HDMI is PCM Multichannel. When I play movies (e.g., Netfix or DVD) or music (e.g., pandora) on the mini, I don't get any sound on the center channel in multi-channel mode. In direct mode, I only get sound in the front left and right speakers. I'd like to have normal surround sound.
Is there not a way to get 5.1 surround sound from the mini? Or, am I missing a set up or something? If I connect my receiver to the mini with the digital audio output, will I then receive digital audio?
Thanks.

Welcome to the Apple Discussions!
Mike it is my understanding that if you want 5.1 Surround sound that you must connect the mini directly to the SS system and not pass the audio signal through another device.

1/4" with optical audio output

Does anyone actually use the digital audio output? Like in a home theater for Dolby Digital? Does the MBP output DTS?

The digital audio output works great. As an audiophile, it's one of the best things about my MacBook Pro. I use mine to not only connect directly via optical cable (toslink) to an external DAC, I can use my MBP as a digital front end for my audio system. I also use my Airport Express to stream music digitally to my pre-amp. The great thing is there is no signal loss between my MBP (source) and the preamp or DAC. This is completely different from using the audio output jack in an analog manner. The difference is astounding. You can buy an optical cable, also called toslink, fibre optic cable, fibre cable, online or at most big box electronics stores. Not all cables come with the mini adapter though, so make sure to find one that does. Monster makes one for about $40, but you can find them online for as little as $6 (before shipping.) The absolute best deal I found was from PowerMax.com. Delivered, this cable was less than $20! The cabling is small in diameter, but it is high quality and the mini adapter snaps into solidly into place. It is a great product at a great price and will make an extraordinary difference compared to analog. Find it here: http://www.powermax.com/parts/show/serv-922-6540 It's made by MonsterCable (MonsterCable is labeled on the external shielding.) It does come with a mini adapter and will work with all the Apple optical digital inputs and outputs. The digital audio output will export Stereo, Dolby Digital (Stereo, 5.1 and 7.1) and DTS. It's a pure digital signal. I can connect my MBP to my 50" 1080p HDTV and use the optical digital out to output the audio in Dolby Digital 7.1 into my audio system. Awesome! Apple was genius to design the audio jacks (input and output) to accept both an analog and digital cable in the same jack. For less than $20, try it, you'll love it. Also, regarding Apple's Airport Express; I rarely used my Airport Express in an analog manner. I couldn't stand the loss in sound quality. I mean, what's the point of having your music in a lossy format stored on your computer if you can't get that same high quality out of it. Using the Airport Express in an analog manner, the degradation in sound quality isn't even worth it (for me.) As an audiophile, quality (both the recording process and the playback process) are everything. By connecting the Airport Express with an optical cable to my pre-amp or DAC, I use it almost daily to stream music and now can truly used my MBP as a digital front end and music server. It's one of the greatest upgrades ever in my audio system and it was only $20!

HT201343 Apple Tv mirror + Airport Express audio output = How to?

I want to mirror my MacBook to the Apple Tv but I want to send the audio to the Airport Express.
If I ask my Apple Tv to send the output to the Airport, it works just fine.
If, after that, I use the iPhone to mirror the screen and watch some video on youtube or Twitch, it works fine either.
But if I use my MacBook Pro to mirror the screen, the audio output is sent to my TV through the HDMI cord.
Is that any way that I can solve this?
What I want to do is just mirror my MacBook screen with the audio coming out through the Airport Speaker.
Thanks for any help, folks!

Hi wennberginho!
I have a couple of articles that should be able to help you with this issue. If you have a 1st generation Apple TV, you will want to reference this article:

2 Tracks, 2 different audio outputs:

I have two tracks, exactly the same. However, one track (track 1) has a metronome click, the other does not (track 2). My laptop is connected to a Mackie Pro FX12 mixer. I am connecting my laptop to the mixer via the laptop audio output jack connecting to a tape input on the mixer. I would like track 2 (no metronome) to run through audio speakers and track 1 (metronome) to run through headphones. Both the speaker and headphone outputs are on the mixer. What do I need to do with Logic Express to make certain that the tracks are run through the correct output?

I'm having some problems with this as well. I want to have one track playing on one output (headphones) and then another track playing on another output (speakers). I have panned each track, so one is on full left and the other on full right. But I don't understand what to do now? How do I route each track to a different output? I don't know how to do this.
Many thanks in advance for your help.

Audio outputs on VMS. What kind?

I left fios a few months ago due to cost, but just got an offer to come back at a really good deal.
I am able to get the new media server, but have a question about the audio output.
Is there only an optical output or both an optical or coax audio?
Solved!

Justin I dont think you understand what I'm talking about. I know the client boxes have a standard coax line for sd tv's and composite outputs, but they do not have a coax digital audio output which is what I'm talking about. There isnt one in the pic you provided or the description....only the optical audio output. On the main boxes theres both an optical digital and a coax digital output, but the client boxes are missing the coax digital.
You are using the word "coax"; there is absolutely NO coax audio output on the VMS1100 server box. there IS, however, a Digital Audio (RCA)* connector present on the VMS1100. But notice the * present on that title; in the Arris VMS1100 Installation and Operation Manual there is the following line after the pictorial of the back of the box:
"*This option is dependent upon application setting and availability in content."
Now I have no way to know whether Verizon has chosen to activate that connection or not because I have no reason to use it, but note in the following pictorial that there are several connectors that have the * in their description, and we know that, at least for now, some of them are not activated.
So yes, I guess there is a connector present on the sever that would work for you (if it is active) that is missing on the clients. Seems a little strange to me that Arris would design things that way, but not much any of us can do about it.
Unless you need that RCA audio connection on multiple boxes, why not just put the server where you need that connection and put the clients in the other locations? Wouldn't that work? I have my server in my office, but really there is no reason why it could not be in the game room or the bedroom.
Good luck however the situation turns out for you.

Audio Output Corruption when using USB MIDI keyboard controller

recently, i'm getting intermittent corrupted audio output (short blips of distortion) while playing through my usb midi keyboard. i thought maybe some data got corrupted on the disk over time so i wiped the drive, reinstalled osx, installed all updates, hooked up usb keyboard and all worked fine. today, i plugged in the keyboard and the distortions have reappeared. i unplugged the keyboard and played with the Musical Typing- still distorted. i rebooted and tried Musical Typing- still distorted. I removed the usb midi keyboard device from Audio MIDI Setup, rebooted, and the distortions have disappeared when using Musical Typing. Connecting the keyboard causes the distortions to reappear. I'm at a loss.
Any ideas?
environment:
macbook pro
osx 10.4.11
gb 4.1.2
studiologic vmk188 plus

UPDATE:
I decided to try going through an Firewire Audio Interface instead. Keyboard-(MIDI)->MOTU Traveler-(Firewire)->MacBook Pro.
Same corruption/hiccups/choppy playback.

No Audio Output Device is installed

Hi,
I have a brand new Pavilion Sleekbook 14-b029TU running 64bit windows 8. product no: c7e65pa#abg.
to the right near the speaker is a red cross. when i hover the mouse over it it says no audio output device is installed. i followed all the ideas on the internet, all the trouble shooting on these forums and on hp help to no avail.
also, when i requested online support, my model does not come up in the options so i couldn't get help that way.
So if i right click on the speaker and bring up the sound options and look into them, they say that there is no audio output.
i went into device manager as suggested by hp, went to hardware, sounds, and checked and under sounds there is:
intel (r) display auto
high definition auto drive
they both say they are enabled.
what's the problem?
please i've tried so many options. i updated. turned off and turned on my computer etc etc to no avail.
i'm losing my mind. this is a new laptop. i don't understand why the hell this is not working???
PLEASE PLEASE HELP

What you are describing seems as if the sound device mute might be enabled.
Hold the Fn key down and tap the F11 key once. That should enable sound and remove the red cross in the systray over the audio icon.
Best regards,
erico

Straitstrider67, welcome to the forum.
What is the make/model of the speakers that you are installing? This will help me understand how they should be connected. There are several ports for connecting the speakers on the Back I/O. Once I have the information that I requested, I will see what I can do to help you get them up and running.

Hp pavilion zv6000 "no audio output devise is installed"

Hi
I have a big problem with my HP Pavilion zv6000. It`s a very old notebook but was working fine till i install win7 ultimate.
I understand that HP doesn`t have drivers for win7 but i hope that you will have some decision for me.
The problem is that i don`t have keyboard and no audio output device installed.
When i go to start menu > device manager > i don`t have audio,speakers and sound ( i don`t really remember what was ) and i cannot fix the problem from there. When i go to troubleshooting, cannot find and fix the problem. And i can`t find driver for win7 ultimate for HP pavilion zv6000.
The other problem is my keyboard. I saw some solve problems like this here in the forum i downloading HP QUICK LUNCH BUTTON and i install this but i doesn`t work again. I deinstall this and i install sp44777 again the same no working, and i try is well sp845(something) again recommended by you but it doesn`t work again.
I really don`t know what to do next. Please if have any chance to help me i will be very pleased and happy.
Thank you very much in advance.
Regards Mimi

Hi, Mimi:
Try this audio driver for your notebook. It is for Windows Vista but it should work on Windows 7.
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=US&swItem=ob-476...
I would try the quick launch button driver made for your machine. They are for Windows Vista so again, they should work on Windows 7.

My speakers don't show up as an audio output. How do I fix this?

I honestly have to say that everything was fine yesterday, but somehow I can't select my speakers as an audio output. When I searched many forums about this problem, people seem to think there's an option for that in the sound settings. Well take a look at this:
I use Bluetooth headphones for the time being, but that's just an uncomfortable temporary solution. Also, weird enough (yet probably somehow not coincidental) my mic gave up on me as well. I get basically the same screen:
I also have no clue of how to remove that Procaster Audioredirector, and to be honest, it drives both me and my dad completely nuts. Is there anyone who understands this? If so, please do help!

How can I link my daqmx code to another daq assistant to hear my audio output?

Hi,
I got a burning question about my school project. I need to use labview and my NI-mydaq to test the difference between
various samples rates and bit depths.
I linked an mp3 file to the AUDIO IN of my NI-mydaq and created a way to be able of switching sample rate while running my program.
Now I would like to link my program inside the NI-mydaq to my AUDIO OUT...
So... I generated daqmx code out of an input daq assistant, how can I link my daqmx code to another daq assistant to hear my audio output?

Hello Fontys_Student...,
I am not sure I properly understand your question.
You want to, first, acquire a signal from the AUDIO IN input, second, do some processing on the acquired signal and, third, generate this processed signal at the AUDIO OUT, right? What is the part causing some troubles?
If you already have the signal acquired and processed, you can simply wire this processed signal to the "data" input of a second DAQ Assistant, right?
Did you already have a look at the myDAQ User Guide (http://www.ni.com/pdf/manuals/373060e.pdf)? On page 32-35, there is an example showing what you need I suppose.

Audio output port moves and wont let me plug in my cable

Suddenly, when i try and put in the audio jack for my 2 speakers into my iMac it seems to not click in. When i shined a flash light at it the port it seemed to move when i plugged in the cable. This has all happened rather quickly which is making me confused. I use my iMac for gaming and never plug in cables with a heavy hand as i am young and i promised to look after this iMac. After understanding what has happened, i ask my parents what might have happened and they did not have a clue. My question is whether it is normal for the silver ring inside the port's hole usual moves and why my cable isn't clicking in.
EDIT:
- I have tested multiple audio output devices like speakers, earphones and headphones and it still wont click and it still moves.
- My iMac is running with 8gb of ram, Intel Iris Pro 1GB Graphics card and 2.7 GHz Intel Core i5 processor.
If you need any more details please request them.

Clean the lint/debris from the connector.
