Suddenly no Sound - Audio Midi Setup helps only for a while ...

Hi there,
using my iMac (early 2008) it sometimes happens (since the update to 10.6.8 ?), that I suddenly do not have any sound at all (volume is up, no mute active). After a while I discovered the hint also placed in https://discussions.apple.com/message/15943204#15943204 as a solution once, but it annoys me to have do that every other day or so.
Fast User switching is active and usualy two users logged in, sometimes more (children).
I have not discovered any pattern, that could lead to this phenomenom. Any help appreciated.
Have a great year!

I'm using a Logitech Webcam Pro 9000 (which has a microphone on the side). I have several other devices plugged into separate USB slots: a keyboard, a mouse, my iPhone, and a Roland keyboard midi controller.
I've considered that maybe the webcam/mic combo is the culprit. If USB doesn't work at a constant speed, that could very well be causing the issue! The sound begins to lag badly sometimes when it's working properly, so that there's a multisecond delay between speaking and hearing my voice repeated back over the mic which is another sign that something is wrong. I've also caught it making a strange electronic sound during its "hang" time once it stops taking sound input correctly.
Maybe I should try to use line-in and forgo USB altogether then. I think I'd need a preamp and some sort of converter for that since the Mac Mini lacks a powered mic jack. I'm only a newbie musician so I've never set up such a system but it might be a better solution in the long run.
I'll check to see if it hangs before or after my computer enters suspend mode, that's a good suggestion too. Thank you for your help!

USB mic/Audio MIDI setup help.

I'm going crazy and have spent two+ hours today trying to resolve what should be a simple issue, especially since I had it working at one time...
I'm looking to set up my USB mic in Logic (MXL USB.007, if it matters). First, in going to my System Prefs > Sound, I can see that it is indeed registering sound. Simple.
So I go to Audio MIDI Setup, as I've seen on the boards. Though the mic automatically shows up as "USB Audio Codec", I'm following the process to create an aggregate device (as shown here: http://support.apple.com/kb/HT1215). Since after doing this, it's not working, my newbie Logic 101 question is, then, what is the correct setup I'm looking for? My choices are USB Audio Codec In and Out, and Built-In Input, Output and Microphone (I'm assuming I should use USB Audio Codec In and Built-In Output).
After this I've gone to Logic's Audio Pref's and changed it to the Aggregate Device, but the mic produces no sound and the audio track monitor doesn't move.
I'm completely frustrated and would be very appreciative of some help. Thanks.

Okay, after much hair pulling, it had to do with my Bus setting on the track. (sigh) What do I know...I'm a singer-songwriter, not a producer.

Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?

Premiere Pro CS6 does not recognize USB PnP Sound device connected to iMac OSX even when activated in Audio MIDI setup. The iMac(i-7 processor,16 GB) is working with this USB device without any problem

Premiere Pro CS6 does not recognize the USB PnP Sound device in order to produce a commentary sound track. The USB device has been activated on the iMac OSX by using the Audio-MIDI-setup and is working correctly with the iMac. When opening > presets >audio hardware I can only select between >standard >out integrated > digital input integrated >microphone integrated. USB PnP is not indicated at this place.
With the built-in microphone of the iMac I can produce the commentary sound track, but I would prefer a stand alone version for better quality.
Your help is highly appreciated. Thanks in advance, Annemarie!

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.

Quicktime no sound, i've already adjusted Audio MIDI Setup

Seems a lot of people have had a similar problem with Quicktime of AVI files not having any audio. I have adjusted the Audio MIDI Setup per the instructions i've found, but could not adjust the Default Output to "Speakers" because it is not an option on that pull down menu. Only option is Built In Output.
Any suggestions?

Audio MIDI Setup not working, please help

Hi,
I am using a macbook pro with Lion OSX 10.7.4. I've been trying to setup my ipad as a wireless MIDI controller but when i open up network in the MIDI window in Audio MIDI setup i just get 'MIDI device properties', instead of midi device setup.
I also noticed that there is no com.apple.audio.AudioMIDISetup.plist file in my preferences folder.
Any advice would be much appreciated.
Thanks

Try dragging the following .plist(s) to the desktop and rebooting:
com.apple.audio.AudioMIDISetup.plist
com.apple.MIDI.0016cb8a99c1.plist
com.apple.MIDI.001b63933178.plist
They are in
~/Library/Preferences
If you still think you need to reinstall the entire app, use Pacifist and extract it from your original Leopard DVD.

Need help with GUI Scripting Audio Midi Setup

I want to read the value of the sampling frequency set by default in Audio Midi Setup.
If there is an easy unix way to gleen this, please let me know. Otherwise, I am trying to get it via GUI scripting. I think I am almost there, but am doing something stupid.
Here is what I have:
tell application "Audio MIDI Setup"
activate
end tell
tell application "System Events"
activate
tell application process "Audio MIDI Setup"
select window 1
select group
select tab group
select group
select combo box
set FrequencyValue to contents of combo box
end tell
end tell
Basically, this comes down to the question of how to extract the default text field from the combo box.

Once you click on the combo box to get the list of items, you can do stuff with the results. The easiest thing would probably be to use the up and down arrows to change the selection, since the text field is not editable. You can compare the list of items with the current value and do something from there - how do you plan to choose the item to change to?
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
font-weight: normal;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #DAFFB6;
overflow: auto;"
title="this text can be pasted into the Script Editor">
tell application "Audio MIDI Setup" to activate
tell application "System Events" to tell application process "Audio MIDI Setup"
set comboBox to combo box 1 of group 1 of tab group 1 of group 1 of window "Audio Devices"
set frequencyValue to value of comboBox -- get current value
click button 1 of comboBox -- perform action "AXPress" to drop the list
set theChoices to value of text fields of list 1 of scroll area 1 of comboBox -- get all the values
-- keystroke (ASCII character 31) -- down arrow
-- keystroke (ASCII character 30) -- up arrow
-- keystroke return -- select and dismiss the list
end tell
activate me
choose from list theChoices default items {frequencyValue} -- just show the results

No multi-channel available with HDMI output in Audio MIDI Setup on Macbook Air mid-2011 !!!!!!!

Hi everybody !
I am currently facing some problem with seting up a surround sound system.
I looked everywhere on the web but i couldn't find any proper answer to this problem.
To sum up, i want to have a Dolby Digital or DTS surround sound when i'm playing a movie (with an AC3 audio track obviously).
I have a Macbook Air 13" Core i7 connected to a SAMSUNG Plasma TV via an iWires thunderbolt -> HDMI cable (bought on the same time as the MBA). This TV is connected to an amp via an optical cable and this amp to a 5.1 system.
When i am going to Audio MIDI Setup to configure the HDMI output, i cannot select any multi-channel option, only stereo !!!!
Is someone has any idea how to solve this problem ? I am struggling a lot and spent hours on that without finding any solutions !
Thanks a lot for your time !

Hello ckkzzzle,
I was looking into the issue you are describing and think I have a great article to help troubleshoot it. The article is called Apple computers: Troubleshooting issues with video on internal or external displays found here: http://support.apple.com/kb/ht1573.
Start here, and work your way down as needed:
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
If more than one video adapter is in use—or "daisy-chained"—troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
All the very best,
Sterling

Kawai CN41 electric piano will not show up in Audio MIDI Setup.

Hello,
I have a Kawai CN41 Piano that I would like to connect to my Macbook via USB to control some midi functions in Logic Express (incredible software by the way...)
The Manual that came with the piano says that it should just work. But for maximum clarification, I'll retype what the manual says.
"The CN41 piano can be connected with a personal computer with a USB cable for excahanging MIDI data. You need a USB Driver installed in your computer.
[For Windows XP/ME users]
A standard USB driver is already installed in your computer. You don't need to install a new driver.
[For Windows 2000/98SE users]
You need to install the desigated driver in your computer. Visit the KAWAI website at http:/www.kawai.co.jp/english/Download1.html and download the program.
[For Macintosh users]
Macintosh OSX automatically recognizes our USB interface. No Special driver is needed. Older Macintosh OS are not supported by us. If you have an older Macintosh OS, please us an appropriate MIDI interface and MIDI cables when connecting the CN41 piano to a macintosh computer.
NOTE:
When both MIDI jacks and USB port are connected, USB has priority.
When connecting USB cable to the CN41 piano, first connect the USB cable and then turn the power of the CN41 piano on.
It may take some time to start communication when the CN41 piano is connected to the computer via USB. When USB communication is unstable with connection via hub, connect the USB cable directly to the USB port of the computer.
Turning the power of CN41 piano on/off or disconnecting the USB cable while the follwing actions may cause unstable communication.
while installing USB driver
while booting up the computer
while MIDI application is working
while communicating with the computer
while the computer is in energy saver mode
* If you have any problem with USB communication, consult the instruction manual of your computer and check your computer setup.
* The USB-MIDI conversion board TID10000934 used in the CN41 piano is approved to show the USB logo. The USB logo can be used only for the product which is approved by USB-IF (USB Implements Fourm Inc.) test.
* Windows is registered trademark of Microsoft Corporation.
* Macintosh is registered trademark of Apple Computer, Inc."
So when i follow the directions just like the manual says the only thing that happens is my mouse stops working for about 30 to 45 seconds. After it starts working, nothing whatsoever in the department of MIDI. It won't even show up in the Audio MIDI Setup application. Also, I'm not 100% positive about this, but I don't think it's showing up in the System Profiler as well.
I've tried pushing the rescan button in Audio MIDI Setup, nothing.
I've repeated everything with a different usb cable with no improvement.
And I even contacted Kawai Technical Support. The guy I talked to via email said that he wasn't a mac guy but he'd ask his friends who were if they had any problems, his friends told him that everything was working fine for them. Then he told me to go and buy a USB-MIDI interface and plug it into the traditional MIDI ports on the CN41 and see if that would work. (I really don't want to do that, one of the reasons I bought this piano is the midi-straight-to-computer-via-usb-cable-connection connection. Buying a little usb interface would defeat the point. Although, I'll probably buy one down the road eventually. I would just like it to work.)
This piano is really nice, It has keys that feel like the real thing and using it to write some tracks in Logic Express would be a delight if it would work. If I could, I would take this issue to the Apple store in Salt Lake City, but I'm thinking that I would also have to take the piano and its kinda big. I'm using a Macbook running OS X Leopard 10.5.4 with a 2 GHz Intel Core 2 Duo processor and 2 Gigs of ram. I also run a Line 6 Toneport UX2, I'm not sure if there could be any Hardware conflicts, but I'm not much of a computer guy so I figured I'd just let you know as much as I can.
Aside from this thing with the piano, OSX has worked beautifully! I will never buy a Windows running machine again. And the few times when I'm forced to use one, (Work and stuff) I get really cranky.
Thank you for your time,
Jon Worms
P.S. I'm more than willing to scan the manual and email it for you upon request, I tried to find a link to it somewhere with no luck. But you know, thats just my luck. :P

Hey Rob, Thanks for responding!
As far as I can see there is not. The piano does have 3 usb ports on it though. 2 A size ports to go to Kawai approved devices, such as a hard drive for recording directly to portable memory. These plugs are labeled USB to Device. Then it has one B size plug that is Labeled USB to Host. The manual says that this is the one to connect to the computer.
USB Controls do exist though. But manual states that they are for when you plug in a small hard drive/flash drive. The controls allow you to create new folders and move recordings around on a flash drive. And without a hard drive plugged into one of the A size ports I don't get anything but an error message.
Tomorrow I'm going to try and get it to work on a windows box. Maybe i'll have a little luck.
Thanks for your help.

How do I get my Built-in Mic to work in Audio MIDI setup, grayed out 1

My iMac is over a month old, and the first week I had it I tried to talk on Skype with a friend. My mic wouldn't work, and after making an Apple Care appointment with a local Mac store last weekend, we found out that the iMac DOES hear me, Dictation works with my voice, but for some reason Skype won't pick me up. Another program I sometimes use is Livestream Procaster, and neither pick up audio from me, oddly though they do pick up finger tapping on the desk, which is no further away from the computer than I myself am.
I Googled this issue with Skype and I found this page:
http://community.skype.com/t5/Mac/Apple-IMAC-Internal-Microphone/td-p/305172
It shows a screen capture using Audio MIDI Setup, and I opened mine to make sure everything was in order, but my CH: 1 & 2 are both grayed out, so I can't adjust them at all.
I have a screen capture of my window as well:
And I did check to make sure that my Interal Mic is selected in Skype, Livestream Procaster, and even my iMac's System Preferences. I wonder if it has something to do with this Audio MIDI Setup. I don't actually know, but from searching for solutions, this is the only thing that doesn't seem to match up with suggestions I've found online.
Thanks guys for any help.

I'm talking with a friend, and he says I'm muffled, and he can't understand me but can hear that I'm talking. When I turn on dictation to record what I'm saying he says I come through crystal clear.
The problem is I don't know if this is a Mac issue or a Skype issue. I was going to go to Skype, but when I found that page that I linked to above, that's what lead me to believe it's a Mac issue again because I can't get my Audio MIDI Setup to match the suggestion made by the user in that link.

IMac won't recognise USB MIDI keyboard in Audio MIDI Setup

I upgraded earlier in the week from a G4 eMac to a new Intel iMac. All appeared well until I tried to use my Evolution MK-361 USB midi keyboard from inside Logic. No midi events were coming through the system.
After some fiddling around I found the Audio MIDI Setup utility and the keyboard is not listed as a device in there. However, if I open System Profiler and select the USB information I can see that the keyboard is connected. According to the E-Magic web site this model of keyboard is class compliant and so shouldn't need a driver installed.
Originally I had the keyboard plugged into a USB hub. I've tried restarting the machine, restarting the machine with the cable plugged into different USB ports and different USB cables plugged into different USB ports. I've also downloaded all the latest OS / firmware / application updates and installed them.
I reconnected the keyboard to my old eMac and it shows up on there so I know it's not a fault in the keyboard itself.
The only other bits of gear connected to the machine are a Lacie external hard drive and my Saffire but these are firewire device so I wouldn't expect them to cause a problem (they certainly didn't on the eMac).
If anyone has any ideas I would seriously appreciate the help. As you can imagine I'm pretty gutted having forked out a grand for the machine.
Cheers
Jon
iMac (Intel) Mac OS X (10.4.8)

Hi Jon
So much for plug and play
Yeah, it's great isn't it?
I emailed M-Audio tech support about it and apparently it's a known problem in 10.4.8 and they're waiting for a fix from Apple. I guess I'll just have to keep my eyes peeled for OS updates and go rummaging under the stairs for a midi cable instead.
Ho hum.

I am unable to adjust the Master volume in the Audio MIDI Setup utility.

For either built-in Input or Output. The systems effected are:
MacBook Pro, 13-inch, Mid 2012 (Mac OS X Lion 10.7.4 11E2617).
iMac, 20-inch, Mid 2007 (Mac OS X Lion 10.7.4 11E53).
The volume can otherwise be adjusted via the Sound sytem preferences or the volume control in the Finder's menu bar. I can even adjust the volume for the individual channels for Buil-in Input and Output within Audio MIDI Setup. It is only the Mater volume that can't be adjusted.
Does anyone have any insight as to why this might be? Any assistance would be much appreciated.

I have Iphone4s 16GB, IOS7.0.4 updates having a problem , that when i press + or - volume keys while my iphone is ringing my iphone 4s goes silent .
Whereas you know silent key is used to make the ringing phone silent. This button is working ok while only problem is my iphone goes silent while pressing + or - volume keys as these keys should increase / lower the ringing volume . These keys were ok working in IOS 6.
Where as these keys are also working ok in music player of iphone for IOS 7, the only problem is for ringing.

Audio Midi Setup, multichannel speakers, Snow Leopard & possible bug

I scoured this forum as well as the usual places across the net and haven't seen any mention of this issue, thought I'd post it here and see if anyone else has had this issue. I'm having a problem with a fresh install of 10.6.2 that I detailed in a bug report to Apple. Here's what I sent them:
"I have a firewire audio interface I use successfully with Logic Pro/Quicktime Pro 7/Finder in a multichannel (5.1) configuration for scoring and post, which works fine in 10.5.8. I can play multichannel (interleaved) 5.1 files bounced out of Logic Pro in Quicktime Pro and from within the Finder using QuickLook, and all channels play out of the speakers (which is of course configured properly in both Audio Midi Setup and Logic Pro).
In the latest version of Snow Leopard however, even though multichannel audio works fine in Logic Pro (probably because it has its own multichannel speaker config in Logic's audio preferences), this same hardware setup does not work outside of Logic. Multichannel audio files only play out of the left & right channels (C/LFE/Ls/Rs are summed). I believe the problem is Audio Midi Setup. Even though I enable the correct stream and choose the correct speakers from with "speaker configuration," and even though the test tone buttons work over the appropriate speakers in that window, after I hit "apply," when playing multichannel audio files in QT7 or via Quicklook in the Finder, the problem persists (summing all channels to L & R speakers).
Furthermore, when I click "Done" in the speaker config window and quit Audio Midi Setup and re-open it, the speaker configuration window reveals that my multichannel setup has reverted to Audio Midi Setup's intial state: a 2 channel (stereo) setup. I've done this at least ten times, as well as having deleted the AMS prefs and launched the utility in 32-bit mode with no success."
Has anyone else with a multi-speaker setup had any problems with AMS initializing their speaker configuration, and just plain not working?

I don't know if this will help you, but I once had a problem with Audio Midi Setup forgetting its settings - I found that the settings were only securely stored if I made the changes while logged on as an administrator.

Built in microphone not an option for Audio MIDI Setup

Hi! I am using a Macbook Pro, updated up to 10.7.5 I can't update any higher due to lack of sufficient memory. Anyway, I've been trying to use Soundflower to begin recording Minecraft videos, and upon setting it up I noticed my Audio MIDI Setup does not have the Built in Microphone option. Without it, I cannot use Soundflower. I watched videos back when 10.7.5 was the newest update and they have this option in their Audio MIDI Setup. Why don't I? Can someone help me figure this out?

Hi krk102588 - welcome to the forum!
I've just come across your post, and cannot believe that no-one replied to your issue before now!
So if you're still around......
You just click on the iMovie tool with the microphone icon on it. That opens a floating window showing audio levels etc. Click on a clip where you want the voice-over to occur, and after the 'getting ready' beeps, start talking! Simple. No need to fiddle with System Prefs/Sound, unless the Internal Microphone is not selected.

Suddenly no Sound - Audio Midi Setup helps only for a while ...
