Output sound on IMAC OS X

How do you get sound output from BOTH a USB speaker and the headphone jack at the same time? I am trying to drive a headphone speaker driven wireless speaker on my deck while still have audio on my imac. Thanks!

If each output device appears individually in the sound output preferences then you can use Audio MIDI Setup (in Utilities) to create an aggregate device to send the output to both output devices.
Note this will work but there may be some problems with adjusting the volume. If each device has its own physical volume control this shouldn't be a problem.

Can I put ALL the sound output from my iMac through Airport?

Just got Airport Express, and managed to install it very quickly on my existing Belkin network. Just don't forget the $ before your WEP key.
Does anyone know if its possible to put ALL the sound output from my iMac through to Airport, rather than just iTunes? So internet radio, streaming videos etc?

Thanks matey - that's just what I was after.
Not sure if that will also let me put my iMac's system sounds through my HiFi - probably not - but then who in their right mind could possibly want to...?
(Be nice if you could though)

How can my iMac output sound to 2 devices?

No sound on iMac in target display mode

I've got a late 2009 27" iMac running Yosemite.
When I connect either my MBP (Yosemite, late 2011 15") or my wife's rMBP (Mavericks, 2012 15") to the iMac using a mini Display Port cable and switch the iMac to target display mode using Cmd-F2, sound no longer works.
Previously, when the iMac was running Mavericks, the laptops would route sound to the iMac via HDMI audio (I think) on the mDP cable and sound would be output via the iMac speakers or headphones attached to the iMac. Since upgrading the iMac to Yosemite, sound no longer plays.
This occurs regardless of the laptop OS, Mavericks or Yosemite. The sound icon on the laptop get greyed out and shows that it is going to the "Color LCD" but no sound is output via the iMac.
Any thoughts?
Thanks

Humm... I might go TosLink between the iMac and the FastTrack and then run the USB connection to the MacBook Pro when your using it in Target Display Mode.
Or vise Versa, leave the USB connected to the iMac and use the TosLink connection for the MacBook Pro.

Output sound distortion when USB Mic Connected

Hi everyone,
Really appreciate anyone’s help on this sound distortion problem.
I have been using the new 2014 iMac 27' for last 8 Months, bought Brand New, and recently updated to Yosemite. Everything worked fine including recording, until this update.
I'm using Blue Yeti USB Mic for recording, and few days after the update I was trying to record in GarageBand and the output sound (via headphone connected to USB MIc) started to distort and then suddenly dropped the bitrate/ sound and I could only hear some clicks. I reinstalled the GargeBand, still its the same distortion happens. The sound gets back to normal, only for few seconds, after I unplug the USB cable from the Mic device. And I tried changing the bit rate and again sounds starts to drop after few sec. This happens only when I connect the Blue Yeti USB Mic and sound output from the Mic itself. Same thing happens with iTunes as well. Output sound from Internal mic and speakers are working fine as normal.
I tried connecting the USB Mic to my Windows laptop and its working fine with the Cubase 5 without any problem. So the problem is with the output sound, when external Mic connected.
I don’t know the solution for this. Have checked on every single blog/ thread, sill couldn’t find the answer I’m looking for, to fix this.
It would be great if you have any kind of a solution for the same.

Nope. The larger buffer didn't work. What did work was running a cord out of the 1/4-inch jack from the direct box to a 1/4-to-1/8-inch adapter and then into the mic/line-in jack on my computer. I set GarageBand to use the built-in line-in and had no static problems. It's a stopgap until this gets fixed.

Disable sound on imac in target display mode

Have a question about disabling the sound.
I have a MacBook Pro connected to my iMac by the thunderbolt cable. I enable the target display mode on iMac with a script for disabling some configurations on iMac ( including the bluetooth for mouse and keyboard steal ).
I set the sound output in the MacBook Pro to the iMac DisplayPort.
The problem is now i have both outputs on iMac speakers. i want to disable all sound from iMac but keep the output from MacBook Pro on iMac speakers.
Is this posible?
Thanks.

Labview Synthesiser: Problem outputting sound via MacBook soundcard

Hi all!
First time posting here, hopefully i'm in the right section of the forum. Anyway, i'm a part time student and currently studying a module on Labview in university. As a mini project i decided to build a synth using Labview. I've it mostly built but i'm having a bit of trouble outputting sound to the soundcard. I'm also having a bit of trouble getting the waveforms to play for a longer time period.
I was sort of copying the setup of one of the example VIs (generating sound vi i think) and another vi i found online but i can't seem to get mine to work using my synth design. I've two problems, one is that the waveform only plays for a very short time but the main problem is that i'm getting an error (error 4803) saying the soundcard cannot accomodate the specified configuration but as far as i can see my setup is more or less the same as the generating sound vi (which works on my fine macbook). Obviously i'm missing something so i decided to come on here and ask for help.
I'm guessing the datatype connected to my sound output configure vi could be causing a problem since it has a red dot on the input terminal. Any suggestions on how i should fix this?
I've my vi attached. Any help would be appreciated!
Cheers!
Edit: I've already fixed the error 4803 problem. Had to change the input to the sound output configure sub vi. Now i just have to figure out how to get the sound to play for longer. Any ideas anyone?
Solved!

OK. You have several problems.
The cluster order in your Format cluster is Rate, Bits, Channels while the order in the "sound format" cluster on Sound Output Configure.vi is sample rate (S/s), number of channels, bits per sample. LabVIEW connects clusters according to the cluster order. How to avoid this: Pop up on the sound format conpane terminal on the Sound Output Configure.vi icon on the block diagram and choose Create Control. That will put a control with the same names and cluster order on the front panel. You can edit the names if you wish as long as you do not change the cluster order. The alternate is to Unbundle the data from your cluster control and then bundle it to the input cluster. I show this in the modification of your VI attached.
The VI does not respond to the Stop button until the event structure executes, which only happens when a key is pressed. Fix: Add an event case for the Stop Value Changed event. I show this in the modification of your VI attached.
The VI does not recognize changes in Octave, Amplitude, Osc Select, or Filter Frequency until the second keypress after changing any of these controls. Why? Dataflow. Those controls are probably read within microseconds after an iteration of the for loop starts. They are not read again until the next iteration regardless of when or how many times they are changed. The loop will not iterate until the Event structure completes, which only happens when a key is pressed. The Fix: Event cases for Value Changes on those controls. Note that this does not work because now there is no defined frequency. So, you also need some shift registers. Because of the problems mentioned, I did not put this into the modified VI.
Next, the event structure freezes the front panel until the code inside has completed. This becomes quite apparent when you set the duration to 2 seconds and press several keys quickly. The fix to this and the problem in the paragraph above is a parallel loop archtitecture, such as the Producer/Consumer Design Pattern.
Not a problem but a different way of doing something: Use Scale by Power of 2 from the Numeric palette in place of the case structure connected to Octave. I show this in the modification of your VI attached.
Now to your question about tone duration: The duration of a signal generated by the Sine Waveform.vi and the others is determined by the sampling frequency and the number of samples. You are a student so you can do the math. You need to adjust the number of samples because the sampling frequency is fixed.
The modified VI works fine on my iMac.

Output sound to multiple devices without delay

Hi there
I'm using Audio MIDI Setup on my 27" iMac running Mavericks to ouput sound to 2 devices (both iMac speakers and a Big Jambox, a bluetooth speaker), it works but with some latency. I tried drif correction in Audio MIDI Setup but doesn't change a thing.
How can I output sound to multiple devices without the latency issue ? I'm pretty sure that's possible. Maybe with a 3rd party software?
Thanks

I am not sure how I would do this if I am using Airplay as one output and hard plug for Computer speakers as the second output. The bosie system is in another room (why airplay) and the computer speakers are in a different room. Thanks for the reply.

Change Output Sound Device

Is there anyway to change the output sound device in iTunes without going through System Preference?
I have an iMac with built-in Speakers, and a 5.1 Griffin Firewave over Firewire. I want my music to come through my external speakers but I don't need my system sounds to come through those, right now I can only change it through System preference and haven't found a way to divide them up.
This is do-able in the Apple DVD Player... any thoughts for this function in iTunes? Is there some place I can put this in a suggestion box if it's not already a function?

It is a great pity you are using Leopard. Up until Tiger there was a great little free app called Detour that let you assign separate audio channels for different apps. You could Google "Detour" and see if there is another utility that will work for Leopard?
There is also an app Soundflowerbed that lets you route the output from one program and port it into another. Unfortunately, those programs must have 'audio channel recognition' (not a technical term - I just mean that they must be able to take an input and deliver an output, e.g. like GarageBand). iTunes doesn't.

Output sound volume

The output sound volume on my system (about one month old imac) sounds low. As I remember my old G5 imac playing sounds on a webpage with system volume (the top line on the screen) and browser volume (set within the browser) at a very load volume.
Now, I have set both volume controls to max to hear the sound at all.
Is there some way I can test the sound?

Hi, go to MIDI SetUp (Applications-Utilities) or Spotlight Midi!
Look for the Configure Speakers Box ~ you can check out the sound from each speaker...
(A recent post, suggested keeping the Mac volume @ Low & setting the external speakers to High)

Any automation for output sound level conflict?

I just upgraded my home computer to a shiny new(er) G5 iMac, running 10.5.5. I don't know which of those are the necessary conditions for a change in output sound level behavior that I'm trying to tame. I have generally kept my cordless headphones permanently plugged in, rendering the old machine (G3 iMac, 10.4.11) silent to the outer (quiet) world of my house, including when it does a scheduled startup in the morning with some people still asleep. This worked well until the new machine arrived. Now the machine is still silent (outside of the headphones) all the time except when it powers up -- the startup chord now plays through the speakers regardless of a plug in the output jack. The problem comes with the output sound level. For headphones, the overall sound level needs to be at maximum. But the overall sound level seems to be the only volume control on the startup tones, and it is then at wherever it was set when the machine was last shut down. So if I forget to run the sound level down to 1 or zero before shutting down, the startup blasts everyone out of bed! So: I now have a sticky note on the iMac reminding me to turn down the sound at shutdown, which will usually work. My question: is there a more elegant way? Is there some way to automate the turning down at logout time, say? I'm inexperienced at scripting, but happy to learn. Any and all suggestions appreciated!

There were no responses to my problem, so I will post a resolution. I dug a little, and found there are several add-ons out there for this problem.
One is http://www5e.biglobe.ne.jp/~arcana/software.en.html, which has the elegant interface of an added system preference pane. However, it is in a beta release, and temporary administrator authentication does not work. As far as I can tell, in order to get it to work, you have to login and run with administrator privileges, never a good idea. Maybe someday this app will work.
But I hit paydirt with an app called Psst, http://www.satsumac.com/Psst.php. This does just what I wanted. The interface isn't as elegant; you just run the app and make your settings, then quit. It leaves a daemon process running at every startup that does just what you want: it saves the global audio volume and resets the volume to the Psst setting at shutdown. Then at the following startup, the startup chime sounds at whatever the Psst setting was, then the audio volume is set back to the saved value. You can just forget it's there, having once set startup volume level.
Too bad that Apple didn't build this in the latest Mac OS, but Psst seems to fill the gap.

Directing sound through iMac

Hello I'm thinking about buying a monitor that I can connect to my iMac. I was wondering if I was using dual monitors will I be able to direct all sound through my original iMac monitor or if I was doing stuff on the other monitor will it only come out of those speakers even if I'm on computer. I'm guessing if I'm on other signals on the monitor I.e not using the computer, like tv or on a console, it will come out the monitor speakers or is it even possible to make that go through the iMac?
Thanks

If you connect anything to the sound output port (the mini-stereo jack with the headphones symbol) of the iMac, the sound output will be directed to whatever is connected. So if that second display has speakers and it has an audio cable, connect that cable to the audio output port of the iMac and it will have the sound. If you just connect the display to the video output port, then the sound will continue to come out the iMac's built-in speakers.
There are some devices that output sound over the USB (or even FireWire) connection. In that case, the USB option will appear in System Preferences Sound pane Output tab. Select it on the list, and the sound output will be direct to that device connected over USB.

I lost my internal speaker as a choice in output sound in system preferences. There is nothing on my output list. Now everything is stuck on mute...how do I fix this?

I lost my internal speaker as a choice in output sound in system preferences. There is nothing on my output list. Now everything is stuck on mute...how do I fix this?

It was red earlier, but not now.
Then try again. The red light indicates that an analog plug jammed the digital audio-out port in the "mute" position. The spec for the tip-to-shoulder distance is apparatenly tighter for digital ports than it is for analog plugs.
On my MacBook Pro, I insert the headphone plug only enough to hear that I have proper sound, and then quit pushing. In this photo, the headphones are giving proper sound quality and separation but the jack's stop shoulder, on a pair of name-brand headphones, is obvioulsy not touching the computer case.
The iMac has the same kind of port. Don't stick plugs in all the way--just until you here proper sound.

Help! No output sound

Hi,
I'm in an emergent situation where my Macbook have no output sound. It's a Macbook, but the new lines all call them Pros. Here is what happens:
1. There is a Red Light inside the MIDI port, only in the one where the microphone sign is (the output one). I have never seen this red light before, but after a restart, it went out.
2. I checked System Preference and it says no output control device even though the laptop itself DOES have built in microphone. And the funny thing is, when I restart it, it gives me the 'boo' sound, but when the OS loads and the GUI shows, no sound.
3. I plug in an external microphone, the sound is there. But once, the external microphone is plugged out, the red light shows up again.
Please help,
Regards,
Angela

I did a quick AHT, but funnily, it reports no problem. However, the system shows a 'built in input microphone', but no 'built in output microphone'; it only shows 'built in output'. It's quite terrifying, it works just yesterday, and now, I can't even find it in the system.
I did check Audio MIDI setup application, but the IAC driver is labeled red. I mean, what is wrong with this?

Angela
