Sound Multi Output Device

Hello All, I have used Audio MIDI Setup to establish a bluetooth stereo with the internal speakers on my iMac. However the audio output's are out of synch. The iMac speakers are slightly ahead of the bluetooth speaker. Is there a correction?

Thank for your reply, however it didn't solve my problem.
I can send surround sound over hdmi to TV, and then TV can send it to the amplifier.
What I can not do is to send surround sound directly from Mac Mini to TV (via HDMI) + amplifier (via toslink) - so that I can switch off TV and have sound on amplifier.
I also have the multichannel options options greyed out (as described in this thread: https://discussions.apple.com/message/19584051). But what I am talking about is sending sound as Dolby (which can be done with VLC), not PCM.

How to use airplay speakers in multi-output device without crackling audio?

Hi,
I would like to mirror the audio output from my mac mini to the built-in output and an airplay speaker.
Therefore I added a Multi-Output Device containing the Built-in- and Airplay output, as soon as I activate the airplay speaker the sound is mirrored but unfortunately always with a crackling sound coming of the speakers set as "slave Device"... only the Device set as "Master Device" has clear sound, doesn't matter if it's the airplay speaker or the speaker (or headphone) directly connected to the built-in output.
I've tested this with a mac mini and an mac book air as audio source, same problem. Both were running Mac OS V. 10.9.2.
Does anyone have an idea what I'm doing wrong?

I'm using a 2011 Macbook Pro running Mavericks and current Apple TV (MD199HK/A 3rd generation) when trying to output audio to both Apple TV and built-in output simultaneously I suffer crackling and popping. I have this issue once I use Audio MIDI Setup (under utilities) to create a Multi-Output Devise. Once I use this multi-output devise made up of Apple TV and Built-In Output to get my music to both output devises at once BUT I get crackling sound on either Spotify or iTunes.
I've worked around this issue by using AirParrot. I select Apple TV in AirParrot with Audio enabled. The Apple TV then takes all audio output, then I select the 'Multi-Output Devise created in 'Audio MIDI Setup' and I have playback through Apple TV and Built-In Output without any crackling or popping.
Only minor outstanding issue is that whatever scenario I then run Audio Midi Setup in terms of setting various devises as Master Clock and resampling of sub devise I can't perfect the sync between Apple TV audio output and my local Macbook Pro, but close enough with the slightest hint of echo. Plenty of forums discussing Word Clock sync which is out of my league. Un-ticking drift correction on the 'AirParrot' audio output has them close enough, depends on how easily you can hear your apple TV output from the room where your Macbook Pro is and vice versa.

The device is in use by another process - error - cannot select Multi Output Device - Mac OSX 10.8.2

Dear Adobe Users!
Please help!
I'm using Adobe Audition CS5.5 on a Mac - OSX 10.8.2 (latest version of Mountain Lion) and I'm trying to select a Multi-Output device.
This was working FINE last few days - today, I get an error. I've tried to re-install Adobe Audition and that hasn't fixed the problem. When it first started up it said it couldn't find any audio devices at all.
Please can you help? I'm getting a message saying the device is being used by another process - but it's not being used by anything else at all!
Hope you are able to help! I use the multi output device option so I can record what I can hear. I spent two days trying to sort that out after it all-of-a-sudden didn't work last Thursday.
Now just spent last two hours trying to get Adobe to recognise the Multi Output device - it's been working fine last few days!
Many thanks if you're able to help!

Durin,
May have sussed it! It seems that Built-in output was the way to have it for Audition CS5.5 to record what I'm hearing! Yes, the multi-device needs to be used - but in another settings.
Here's how I have each section configured and it now works!
First of all, in Audition > Preferences > Audio Hardware:-
Then, on the Mac's OS - System Preferences > Sounds (input settings)
Then Output settings :-
Then Midi Settings found in Finder > Applications > Utilities > Audio MIDI set up
All now seems to be working! I'll let you know if anything further happens!
I was certain I had the output device as Multi Device Output on Adobe before, perhaps it should've been set to Built-in Audio all along. Anyway, I re-installed my Mac from Time Machine, logged in as another user and it worked under that profile, then logged back in as me - and am using the settings in the pics above and all seems to be working!
It's been a long week, perhaps I was just going around in circles and didn't actually test these particular settings yesterday in this order after all.
Thanks again for your help! Sorry if I've caused any confusion!

2012 Mac Mini - Using multi-output device?

I'm trying to get my Mini to output sound over HDMI and the headphone jack. This question has been asked before, but the answer wrongly claimed OSX didn't support it. The Audio MIDI Setup program (in the Utilities folder) does in fact let you set up a multi-output device that uses the headphone and hdmi out. But when I try to output sound with that device, I don't get anything.
Before I bought this computer, the Apple Store drone claimed this multi-output was possible. But this wouldn't be the first time I've talked to a complete idiot there.

Some more updates:
using multi-output and having the line out set as master prevents 5.1 surround from being output on HDMI, which is fine for my use. When I have something plugged into the headphone jack (in my case wireless outdoor speakers) the settings app won't even allow the settings app to choose HDMI as the audio output device, which is also likely why HDMI can't be master in the MIDI app.
So to get 5.1 surround back for movies I need to unplug whatever's in the headphone jack and change the output device from the multi-output option to HDMI. It's sad my 6 year old PS3 handles this more elegantly and sensibly but at least I don't have to take back my Mini now

Is there a way to be able to still control volume while using a multi-output device?

I just need to know if I can still control volume while using a multi-output device (or an aggregate device, whichever one blocks the volume changing) because I am trying to record my screen using Quicktime while recording sound on my screen (using soundflower). Any suggestions? I am happy to download an external program to fix it.

Hello,
Well we already found that answer somewhere on a forum, I guess you mean add the URL to firewall exception,
but this doesn't fit Company Security Standard, in my company we cannot allow a computer access internet
directly exception or not, it is very sad that a company such as Adobe is not able to produce a tool that is
Proxy Aware for all it's functions (Software activation, Software Serial Checking etc. all doesn't behave the same way).
We need a solution ASAP as many of our users are not able to use their Adobe Softwares.

HT202000 How can I fix a noise problem in multi-output device?

I've created "multi-output device" in Audio MIDI Setup, added both outputs to the list of devices, so this setup outputs sound to both devices at once. Problem is that there is noise.
Whatever output is set as "Master device", it does not suffer from noise, but the other has frequent loud clicks (just like if audio frame is being ripped).

I'm suffering from the same thing.
Whichever device isn't "Master" suffers from static prickling sound.
Tested between Macbook pro retina + cinema display (using both audio outputs)
Paired with a Bose mini soundlink bluetooth speaker.
Tried playing around with Sample Rates and Drift Correction to no avail

Sound: Changing output device

Turned on my machine and discovered that it had self assigned a program as the sound out put device. It's CD spin doctor from Toast; no audio on it. I removed Toast, emptied the trash and shut down then restarted. It's still listed as the output device. I can't change the device - there's no list - I can't delete it or add another device. any thoughts on how to fix this problem? I have no audio at all.

if there is no audio at all, could be hardware issue.
somebody recommends deleting following preference files:
/Library/Preference/com.apple.audio.DeviceSettings.plist
/Library/Preferences/com.apple.audio.SystemSettings.plist
http://discussions.apple.com/thread.jspa?messageID=10500893
best case it's just corrupted preference files

No Sound - Audio Output Device has stopped working

Hi.
I've recently bought a new HP Pavilion 15 Notebook PC Product Number F4T62EA#ABU with Windows 8 64-bit. The audio device is a Realtek High Definition Audio device.
All was working fine until a few days ago when the audio device stopped working. Here is the device status:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)".
I've tried to update the driver for the device but it is already up to date. Can anyone let me know how this can be fixed please?

Multi output sound device and 5.1 sound

Hi,
I have following setup:
TV is connected to the Mac Mini, with HDMI Cable.
Amplifier (5.1) is connected to the Mac Mini, with Toslink cable.
In addition to that TV can pass sound to amplifier through another toslink cable.
Currently my setup works perfectly:
When I set sound output to HDMI, TV recognizes 5.1 sound (also it can be passed to the amplifier).
When I set sound output to digital audio, amplifier gets 5.1 sound.
Note: 5.1 sound works when I play movies from VLC. In audio setup (in preferences and midi setup) there is only possibility to have 2 channels.
What I want to do is to have the same output to both devices.
I created multi output device, for HDMI and digital audio, and devices get only stereo sound.

Thank for your reply, however it didn't solve my problem.
I can send surround sound over hdmi to TV, and then TV can send it to the amplifier.
What I can not do is to send surround sound directly from Mac Mini to TV (via HDMI) + amplifier (via toslink) - so that I can switch off TV and have sound on amplifier.
I also have the multichannel options options greyed out (as described in this thread: https://discussions.apple.com/message/19584051). But what I am talking about is sending sound as Dolby (which can be done with VLC), not PCM.

Macbook Air Audio Output Device Gone

My sound on my mid 2013 MBA has gone. Under prefeerences, there is nothing under device output. I have restarted several times; no luck. I looked under Mac HD, library, prefs, audio,; but could not find any audio files to delete as per one thread. Under utitlites went to audio midi etc, but could not find any listed audio output device list. I have repaired disk permissions. Done a shut down and restart. But still audio is greyed out, and no devices show up under system prefs, sounds, for output device. PLEASE HELP... I am in Zambia and closest apple dealer is in S.Africa. Thank you.

Go step by step and test.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure that Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
5. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

Help, no sound, no sound output devices

Hi all,
I tried this over in the Tiger section with little help. About a week ago I told my grand-daughter she could plug her iPod headphones into the headphone jack on the the front of the G4. Now, I have no sound at all except for through the headphones and only the headphones show up as an output device. I have tried trashing the "com.apple.soundpref.plist" and rebooting thinking that the OS would creat a new one during startup but that didnt work (there was TWO of them in there). I also tried trashing "com.apple.audio.AudioMIDISetup.plist" but that didnt help either. I put them both back where I found them later. Those files both belong in library-preferences right? I tried zapping the Pram but having no sound I didnt get a "bong" I just listened for it to rev-up twice, still no change. I also tried the PMU reset switch. I can change the volume level with no effect except for the headphones and the sound is not muted.
System Profiler does not recognize apple pro speakers that are plugged in, I do have sound sticks to try but they are boxed up in the garage.
So I am wondering if the phone jack got messed up by the iPod plug, a hardware issue, or does this seem to be software related problem? I did an archive & install today with still no sound so now I am thinking that the plug is messed up inside and still thinks the headphones are plugged in.
Does anyone out there have any advice to offer?
I am going to do surgery next to explore the headphone jack and the tiny speaker above it.

Slimtech,
I don't have a solution for this, but maybe some comments might help a bit...
com.apple.soundpref.plist and com.apple.audio.DeviceSettings.plist should be at /Library/Preferences.
com.apple.audio.AudioMIDISetup.plist should be at ~/Library/Preferences.
The "Audio (Built In)" section under System Profiler for my QS G4 shows no attached devices, but merely shows information about the sound card itself, with three generic outputs listed as "Internal Speaker, External Speaker, and Headphones".
Normally, you should get a startup Chime from your internal speaker even with headphones plugged in, unless perhaps the sound setting is on Mute at shutdown, which sometimes will affect/mute the startup chime at the next startup.
I would think that if the Mac thought that the headphone were still plugged in after removal, your Sound Preference Pane Output window would indicate this. If the Headphones appear in the Output window when plugged in, then disappear when removed (refresh the window by clicking another Tab then going back to the Output Tab), the System obviously recognizes their removal. Apparently, it doesn't recognize the internal speaker that it's supposed to switch back to though, for reasons unknown to me.
You might try vigorously and repeatedly plugging/unplugging the headphone plug into the headphone jack, which helped clean up the jack and restore the sound on my G3 some time back.
Sorry I couldn't be of more help.

Audio icon in upper right menu disappears and there is no sound Went to Apple preferences which says there is no output device. I can't figure out what to do. Help!

There is a sound icon in the upper right menu which disappears and reappears. When it disappears there is no sound. Went to Apple preferences for sound preferences. When the sound icon is off, this page is not active. Says "mute" is activated and that there is no output device. Cannot fix this problem. How do I retrieve the sound icon and get sound back?

Hi Ronnie, anything in particular going on when this happens?
Long shot, but...
Next time it happens... 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

How can I get my audio input and output devices back? I have no sound and cannot see any of the devices in Audio MIDI Setup..??

Hi, I tried to set up a new output audio device on my mac that would have multiple outputs (iBox Twist speaker and my internal speaker) but when I went to click onto one of the iBox Twist (there were 2 options available: iBox Twist and iBox Twist Stereo), Audio MIDI Setup crashed and when I finally got that back open, I found that there were no audio input or output devices to be found. My sound is working, as when I turn on my iMac, the starting sound still plays, however the volume control in the menu bar is no longer a black colour, but grey and when I try to change the sound on my keyboard it does not change. This already happened to me once, and after 3 hours I managed to fix it very simply (switching off Mac, unplugging power cord, leaving for 15 seconds, plug power cord back in and switch Mac back on, holding Alt, Cmd, P and R keys until you hear the Starting Up sound twice) however this same technique that fixed it once before is not working this time and I am still stuck without sound. I have tried Repair Permissions, rebooting in Safe Mode, Hardware Test and checking for Software Updates. Has anyone else had this problem and managed to fix it?
Thanks in advance for any help anyone can give me!

In case anyone has had the same problem as me, I have just managed to fix this by doing the following:
Switch off Mac
Switch back on in Safe Mode (Hit power button, then hold Shift key until a loading bar appears at the bottom of the screen).
Switch off Mac again
Remove power cord and wait 15 seconds
Plug power cord back in and hold down the keys alt, cmd, p, r all at the same time until you hear Starting chime for a second time and hopefully your audio will back.

NO Audio output Device is installed as well as NO sound, video, or game tab in the device manager

Here is the issue I had with with my Compaq F700 series laptop. The sound was working one day and then not working the next. Over the volume icon there was a big red X and the warning that No Audio output Device is installed. I also found that there no longer was the sound, video, game tab in the device manager. It had gone missing.
I couldn't use most of the fixes as they require having the sound, video, game tab available and this tab was, as I said missing. I tried reinstalling the sound drivers from the manufacturer’s website as well as using the driver re-install, but at each attempt it would fail as a result of not having any audio devices installed on the computer.
I tried doing the system restore and rolling it back but the problem didn't get resolved. What eventually worked was restoring the system to a MUCH earlier date, like a month prior to the problem. When the restore finished the sound was still not fixed. HOWEVER, the computer OS (WINDOWS 7) needed to re-install a bunch of updates and after the updates were installed, everything was working. I suspect that the original issue was a bad update (the updates didn't install correctly) and that by rolling the system back to a time prior to the bad updates and then re-installing the update was the fix.
With that said, if the restore option doesn’t work or can’t be done I would try looking through the add/remove programs in the control panel and uninstall the most recent system updates, then restart computer and let the updates re-install.
Good Luck

Only option that I see in the BIOS is under Security. Audio Device: Hidden or Available. It was set to available and I left it at that. Still no audio.
Really? Nothing? This computer is one year old. Absolutely no reason for this to be happening. What a joke.
