Intel Mac :: No Input Or Output Sound Devices Found
May 22, 2012
Just today I have installed an application which was to do with sound switching , called "soundflower" once iv installed and run it there was an option "create multiple sound switch" did chose and start to creating a multiple, as soon as it started my sound card panel display as "no sound card founded" and my sound icon on the top bar turned to light gray.
Double click on that and when it opens you will see your hard drive (usually Macintosh HD) on the left. Highlight your hard drive and click on Verify Disk on the far right. If that is OK click on Repair Permissions on the left. If Verify Disk is not OK try to Repair. If Repair is successful then Repair Permissions if it is not successful let me know. But problem still remains.
I was in Audio MIDI Setup and I clicked one of the checkboxes to add a device to something or something like that and all the devices vanished from the list and sound stopped working. After closing Audio MIDI Setup I am unable to open it again, even after restarting and getting all the updates. Skype now freezes and doesn't load. Sound preferences also have trouble and freeze up if I try to load them. I would really like to have sound from my computer again!
Occasionally after booting back into OS X from bootcamp (windows 7 home premium), I will not have any audio output devices. If I restart OS X again they return, anyone have what maybe happening here? This is on a 09 MP...
I just got this new iMac that I got used and the sound on the computer does not seem to be working, I have tried doing what the computer tells me and going into System Preferences and selecting the sound option, but the sound seems to have been permanently disabled and shows that there are no output or input devices available, when clearly the monitor has speakers. whats more, is that the volume icon does not show up in the menu bar even when I select that I want it in the menu bar.
Hey, my macbook was getting rather slow so I decided to do a clean install of Leopard, but now I have absolutely no sound whatsoever apart from the startup chime! The volume keys now don't control volume and instead do expose and dashboard.
I did however install it with a Leopard disk that was from a shop and not one of the grey ones that came with the computer, is that the problem? If so how can I fix it?
All of a sudden my mini's sound output stopped working and now doesn't recognize any output devices. worked earlier today not now, didn't add anything. system pref - sound - output = "no output devices found
My sound has completely quit working. In the sound system prefs I get a massage saying "No output devices found". If I press the volums button keys the onscreen display comes up but has a 'no access' icon on it (a circle with a line through it). The icon in the toolbar has also vanished and there's just a blank space in its place.
Oddly whatever happened also seems to have effected my ability to view Flash movies -*the will play for a few seconds an then pause *they don't stutter they just pause. I think that whatever the issue is it was caused by a force shut down. All my applications were hanging so I had to press down the power button for a few seconds. Since then nothing!
This also effects the start-up sound which I don't get and all users of the machine are the same so it's not a case of deleting users prefs. So far I reinstalled the latest system using combo updater, run disk utility to repair disk/privileges (from start up disk) and zapped the PRAM.
All of the sudden the sound on my MacBook is no longer working. When I look at System Preferences>Sound>Output it says there are no devices found, even when I plug in external speakers.
I had a first gen aluminum 13" Macbook that I spilled beer on. It was basically a write-off, but fortunately the HD was not damaged.I just got my 13" Macbook Pro today, and replaced the new HD with my old one. Everything is working fine, except that there is no sound.When I go to System->Sound I see "No Output devices found", and when I press the sound buttons on the keyboard, the speaker is grayed out.I know this is not a Hardware issue for a couple reasons. First, it properly 'chimes' on startup. Second, I did try running the computer with the new hard drive, and during the sound was working properly, volume adjustment buttons working, etc.
I can feed sounds into my iMac with line input but no sound comes out vis internal speakers. I can record the input sound using Amadeus and play through gives me sound output. When not using Amadeus although input is set to line in and output to internal speakers no sound comes out. There appears to be some internal disconnection between input and output.

A few weeks ago my MacBook Air suddenly would not play any audio. It would happne off and on. Usually the sound would come back after restarting. Now, though, I can't seem to get my audio to come back at all, no matter what I do. Here are a few screenshots to give you an idea of what's going on: I've restarted. I cleared permissions with Onyx. I verified and repaired disk permissions with Disk Utitlity. Still no audio.

This just happened to me the other day, I plugged a pair of apple headphones in used them and then unplugged them. The next day I noticed that I was not getting any sound from my macbook air, no startup sound, no OS sounds, and even the headphones are not detected when plugged in. I've tried all the tricks and so far nothing.
Of course my mac is just out of warranty at the end of March and I'm going to imagine this is a small fortune to get fixed. Since last time I took it in while it was in warranty they wanted 900 bucks to replace my HDD
Anyone else run across this, I'm thinking of just throwing it on craiglist or ebay for like 900 bucks as is and buying a normal laptop
My MacbookPro sound suddenly stopped working. It was working fine yesterday, but rght after I unplugged the headset, I don't have any sound anymore. I do not have any red light on the audio jack. I do not have any internal and output devices found under the System Preferences. I already tried resetting the PRAM and NVRAM, SMC and nothing works! I have the latest verion 10.7.4, Core i7.
Have read all the threads I can find and tried all the fixes, with no joy. Last posts were end of last year, '11. Anyone got any more info since then?
how to find a way to change the input and output devices for sound without going into System Preference, and I finally got round to a little focussed googling and found this: [URL]
I picked up a really cool wireless USB speaker set and want to use it with my current gen iMac running Snow Leopard. Problem is that as far as I can tell, and I've done some searching, that it's either the USB audio, or my internal iMac speakers, one or the other - not both.
could use both outputs at the same time? Internal speakers and the wireless USB ones?
I have a problem about sound. It's no output or input device when I install parallel desktop 7. Is there any way that can solve this issue without uninstalling Parallel Desktop?
I had a 3,5 mm stereo jack in my audio output on my macbook, and it broke inside. Is it possible to redirect the sound output to go through the input jack?
I have multiple displays connected via the HDMI port and one to the mini port as well and a theater sound system attached to the headphone jack. How do you turn on sound output to both HDMI and headphone jack. If the headphone jack is plugged in, it always defaults to that device. I am unable to hear the audio at the remote displays without removing the headphone jack.
I have an iMac at home. I have two airport express devices with hifi systems connected. I use iTunes to play music, podcasts,radio, .. on the different hifi systems dependent on where I am in the appartment.When using the remote control on the iMac it seems to me that it isn't possible to select the wireless devices for sound output.
My external mike (Samson C01U, USB connection) isn't working; there's no input sound coming through. I'm certain it's not a hardware problem with the mike On preferences > sound, there's no sign of any input (with input volume level turned right up). Trying to record on Camtasia / Audacity / Quicktime also isn't giving any input.

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.
My sound keeps turning off. When I check the settings, the output device switches randomly between Internal and Digital output. I have no idea where the Digitial Output is coming from and this started about a month again. It switches randomly and then I loose all sound for a few seconds. Sometimes it happens once then stops for a few days, other times it switches back and forth for 5 min. No idea!!!Â
My sound output preference is set to mute and is highlighted in light gray so that the preference can't be changed. Also, simultaneously, the sound control in the toolbar is gone and is replaced with an eject symbol that responds "SuperDrive F12" when clicked on.
Speakers work but cannot get any sound output. Running windows 7 on Intel iMac. Speakers sound on booting and graphics in Control panel and on toolbar indicate sound is being recieved but nothing comes out of speakers or headphones.
I have a mac mini (solo intel) 10.4 OSX. I have no audio output when attaching an external input source like a CD player or ipod to the input jack on my Mac Mini. Audio output from ITunes or movies clips in IPhoto works fine. I have checked the cables and connections. I have checked the "sound" location in System Preferences to make sure the "built in output" source is selected. The input volume display shows that the audio input is being registered. I have checked "system profiler" in the Utilities folder in Applications to make sure the "built in output" AKA headphone outlet is recognized.
I have the "Soundflower" App. installed but turned off.
why the audio output from the internal sources like ITunes and IPhoto music clips work but the audio output from an external input source does not? Is there some software or a driver required for audio output from an external source that is not required for audio output from an internal source?
I am trying to format a hard drive that I put in an enclosure, I have two of these drives and the other one works, but when I tried to format the other one, I get an input/output error, I have tried to format it on a windows, and linux box, the windows says it formats it but it just well doesnt, and the linux box would display an error message, dont remember it though. This is really getting on my nerves, It will just freeze the mac, and I get the spinning beach ball.
