No Sound and "No Output Devices Found" in System Preferences/Sound

Sound was intermittent for awhile and now there is no Sound/Output found. Tried the Command-P-R reset but it does not fix problem.

Applications/Utilities/ Audio MIDI Setup.app
Audio Devices window
Side Bar
Click the Built-in Output.
Under Mute any box checked?
If Intenal speakers are visible, try to adjust volume slider.
Make sure that Source: Internal Speakers
Format is set at 44100.0 Hz
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".
If these steps do not help, you may have to take the computer to the Apple store.
Best.

TS1574 I have no sound on my iMac.    When I select the upper key on the keyboard or select 'output devices' in the System Preferences file, it says "no output devices found".     Any ideas as to I can turn on the sound?

I have no sound on my iMac.    When I select the sound keys on the upper row of my keyboard or select 'output devices' tab in System Preferences, it says "no output devices found".    Any idea where I am not looking to get sound back?

Thank you for your responses.    I found the 'sound' icon in the menu bar and found it was turned down low.   I adjusted the sound there and this worked; however, I'm not sure why this didn't show in my System Preferences or why I couldn't adjust the sound from the keyboard.    Those function keys basically became un-usable for me.   Thank you again!

After installing Mountain Lion. Under sound, where it says select an output device, it say no output devices found and there is no sound. How do I fix this? I have reinstalled the os twice and still the same. I have also repaired permissions.

How can I get sound on my MacBook Air after installation of Lion? "No output devices found" on the system preferences pane of my MacBook Air.

Since installing Lion on my MacBook Air, I get no sound and ITunes playback doesn't move. The Sound Preference pane states "No output devices found." The Bluetooth connection to a WiFi speaker works, so it must be a software problem. Anyone?

For sound, try the audio output port and connecting to the RCA audio input ports on your Pioneer receiver. Use something like this:

No Output Devices Found and Track Pad Issues

I bought my Macbook Pro in mid-November 2011. Yesterday I noticed that my Macbook did not have any sound and when I checked System Preferences it gave me the dreaded "No output devices found" message. I could hear a start up sound but nothing after I have already logged in to any of my accounts. This is the first time I encountered it and I did some research so I have already done a PRAM reset, permission repair and I even created a new user account to see if I will encounter the same problem. Same thing on the other user account, still no sound. I also found out that the sound would only come out with a USB headset. Headsets with jacks won't work either.
I brought the unit to a service center and they advised me to reinstall OS X Lion and I did. There was sound right after I reinstalled the OS. However, it was gone again when I did a reboot. I also noticed that my track pad won't respond on certain occasions and I have to do a force shutdown by pressing the power button. What could be the problem? I am fearing that this is a hardware issue. I prefer not to have to bring the unit to a service center, wait for a week to get it back then only to encounter the same problem in the future.

''No output devices found'' message on my Mac Pro with Lion... Any suggestions? What should i do to resolve the problem?

I turn on my mac without hearing the chime boot sound from Apple.. after that im always turning on my Motu (extermal soundcard firewire) i still got that message, by audio midi setup my Motu appears from some minutes and then goes away again.. The same time that my Motu appears i simply start a mp3 file to check if i got a sound but still no luck... Made all possible updates but still no sound.. I'm using Logic pro 9 and have lots of thing here to do.. Try also a hotline from Apple to call but im waiting like more than an hour and still no answer... Please any suggestions? I am afraid it can be a hardware problem
This problem came for the first time after i made an update in Avid Protools...
After that i tryed everything and still got no sound... Next step i FORMAT my Mac Pro.. Back everything UP and reinstall Lion and still '' NO OUTPUT DEVICES FOUND'', i performed a clean install.. Thats why i am afraid it can be a Hardware problem.. So, if anyone of you guys know something about it, please share your knowledge with me..
Thanks in advance

Try a different user account and see if the problem persists.

HT4847 Why is the "done" button inactive when I try to downgrade my iCloud storage plan to 5GB free? Doesn't work from iOS device or macBook system preferences. I didn't sign up for a $40 plan.

Why is the "done" button inactive when I try to downgrade my iCloud storage plan to 5GB free? Doesn't work from iOS device or macBook system preferences. I didn't sign up for a $40 plan.

I found the solution .,,,
1) click on your current plan and press done your payment details will appear .
2) the first section is your plan and there is a botton "change" click on it
3) it will take you back to the upgrade options
4) press on the downgrade options
5) choose the 5 GB and the done botton will be enabled
6) click on it you'll back to the step number 2 , here read carefully you'll see that your changes will take effect after the current plan expired with the date.

It may well be a driver issue but considering the loading: Xorg trying to load different drivers is somewhat normal. @cafe you can see that these are autoconfigured by X above the loading in the log:
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched intel as autoconfigured driver 0
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched intel as autoconfigured driver 1
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched modesetting as autoconfigured driver 2
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched fbdev as autoconfigured driver 3
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched vesa as autoconfigured driver 4
As long as one of the drivers gets loaded, which it apparently does the failing of the others is fine.
Was there an update maybe ?

MBP Retina No Sound Output device found

I use my MBPR with thunderbolt monitor and often use the 'Display Audio' option when plugged into them. 2 days ago, when I unplugged the thunderbolt monitor, there was no longer an 'internal speakers' option in the sound prefs pane.
It does still show the 'Display Audio' option when plugged into the TB display, however that is the only audio option now, other than any available airplay devices in range.
I did SMC reset & PRam reset, multiple times to no avail. I then called apple support and they walked me thru the same things, as well as eventually deleting these 2 plists from the library > prefrences > audio folder:
com.apple.audio.SystemSettings
com.apple.audio.DeviceSettings
This also did not return the audio device to the sound prefs pane.
I had a friend with the same laptop, same specs, send me his version of those plists, as mine were missing sevral keys that his had. None of that worked. Wondering if anyone else has seen their internal audio device disappear on the MBPRs? I read up on HDMI audio threads, but the their problems seemed to be with MB Air & not very relevant to this problem.
Thanks.

Hi-
Does the G4 make the start up chime?
In System Preferences/Sound/Output, is the "Mute" button selected? Is the volume set?
Do you know that the internal speaker worked before you got the G4?
Have you tried headphones or speakers in the sound output jack?
If the output jack isn't shown in the preferences, and you have no chime on start up, you may have hardware problems.
Just for fun, try a PRAM/NVRAM reset:

Snow Leopard - No Output devices found - (Audio) Help?

Folks
I just installed Snow Leopard on my Mac Mini which I use as my home media centre. It upgraded fine except for the lack of audio devices it now reports. Ive been combing forum threads but to no avail.
Appreciate any help or suggestions
Model Name: Mac mini
Model Identifier: Macmini1,1
Processor Name: Intel Core Duo
Processor Speed: 1.83 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 2 MB
Memory: 2 GB
Bus Speed: 667 MHz

Update:
Syetm profiler told me I had no sound device. I did the PRAM thing and the plist thing. no help.
I then pulled opened the mac up and checked to make sure the daugther boards were properly seated ... I was desperate.
When I rebooted the machine, it came up WITH SOUND. I dont think it was me opening the box as it could have also been me booting the machine up with no toslink f/o cable plugged into the output jack.
When the mini restarted I got the bing over the system speaker, and once the machine had started the audio worked perfectly and I plugged the cable back in.
Since the sound has been working I have lost it a couple of time since, particularly after using DVD player. this has ofetn happened as I think it gets tripped up when swthching between 5.1 audio out and normal output. Again this sorts itself out if rebooting with the output cable disconnected.
I hate these type of issues as it seems so erratic. Let me know if starting with the cable out sorts things out.

Keyboard and Mouse doesn't work on system preferences after 10.5.2 upgrade

The keyboard and mouse configuration through the system preferences painel has stopped working after installing the update to version 10.5.2 of the Mac OS X.
This occurs when using the Brazilian Portuguese language. Any suggestion?

I've found a fix here:
http://antoniofonseca.wordpress.com/2008/03/12/correcao-para-o-problema-do-tecla do-e-mouse-no-leopard-1052-em-pt-br/
In short: there's a problem with the Brazilian Portuguese translation, it's the only language affected.

My USB Tascam US-200 audio soundcard can't be found in System Preferences, but can be found in application? (Screenshots inside)

I'm having some issues with my audio since I upgraded to Yosemite 10.10.1.
This is currently what the sound section in my system preferences shows:
Before I upgraded to Yosemite 10.10.1, I had an option for "US-200" on the list to select.
I use music production software Cubase, and that application finds the sound card and allows me to play audio using it (another screen shot below)
I'm just confused as to how an applicated on my Mac can find it, but it doesn't appear on system preferences? Is there a fix so that I can bring my system preferences to show my soundcard so that I can play music from iTunes through my Tascam US-200?
Any help would be greatly appreciated
Thanks

It complains not just about one class, but about EVERY class that's loaded dynamically. When loading classes dynamically in a built exe, you have to specify their locations inside the build profile. This is what's done under "Destinations." Specifically for classes, they must ALL be either inside or outside the exe.
Because my application is deployed to end-users, I want the classes opaque to them, so I set the destinations to be within the exe. This works fine, and the exe builds without problems, with all the classes embedded inside.
The problem is the installer thinks all the classes that have been built into APT.exe are actually located in a system folder called "APT.exe." That's obviously wrong, so when it tries to grab those classes from a nonexistent file location, it returns an error.
I know I'm not the only one building classes into exes, so I can't be the only one seeing this problem.

What is the process for connecting ethernet. Have ethernet cable connected to stereo received for internet radio and Blue Ray. However Network System Preferences indicates ethernet not connected and has red dot to left. Note Airport wireless is working.

What is the process for connecting airport extreme ethernet? I have ethernet cables connected to stereo receiver for internet radio and another to blue ray player. The system preference network indicates "ethernet not connected" with red dot to left of this message. The airport wireless works and has green dot to left of it. The stereo receiver and blue ray player do not respond and give message not connect to internet. Thank you. / cfpirate

It worked for me finally. I took out the DNS numbers in airport admin utility, and restarted the airport express. I do not remember putting the DNS numbers in, I wonder from where the airport express got those numbers.
After restarting, it worked.
Thanks!
