'No Output Devices Found' MacBook Air

May 31, 2012

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.

MacBook Air :: No Output Devices Found - How To Connect

Apr 9, 2009

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

OS X :: MacBook Sound Not Working - No Output Devices Found

Jul 11, 2009

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.

OS X :: No Sound / No Output Devices Found On MacBook Pro

Oct 11, 2009

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?

OS X :: New 13" Macbook Pro - No Output Devices & Sound Options Found?

Jun 10, 2009

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.

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.

MacBook Air :: Can't Get Audio HDMI Output To Work On ViewSonic VX2453 Monitor

Jun 23, 2012

I have a 13" mid 2011 MacBook Air and a new ViewSonic VX2453 monitor. I used the Monoprice mini display port to HDMI converter with audio and connected the monitor to my computer's thunderbolt port. The video works perfectly, but the sound isn't working at all. I set my computer's sound output in settings to VX2453 series (type: HDMI), and I set my monitor's audio input to HDMI. Nothing. I also tried changing the frequency in Audio MIDI Setup, which someone recommended on amazon  for the monoprice adapter, but that didn't work either. 

I tested the monitor's sound by switching audio input instead to "audio in" and connected to my headphone jack, and that worked so the monitor's sound is fine.

MacBook :: Device Has No Output Devices

May 13, 2009

So I started up my macbook this morning and have been using it for awhile when I went to go play some music and can't get any sound. When I hit the volume buttons it shows a shadow of the speaker logo and a circle with a line through it under the volume bar. I have tried a restart and also went into sound controls, where it says "The device has no output devices" . What can I do/what's going on?

MacBook Pro :: Computer Says 'battery Not Found' And Only Turns On While Plugged In

Feb 28, 2012

While unhooking my battery, I accidentally touched the metal contacts near the battery cable connector on my mid 2009 with a screw driver. My computer says 'battery not found' and only turns on while plugged in.  The computer doesn't detect a battery in the system profiler.  Will buying a new battery resolve my issue?

MacBook :: Strange Residue Found In An Otherwise Clean 'BlackBook'?

Jan 10, 2011

A black MacBook that I recently worked on had the most bizarre thing about it.

One of the memory SIMM's had soem residue on the underside of it. It didn't look like water and the system ran fine with it. I used some contact cleaner to get most of it off. I thought that the system perhaps had something spilled on it but the most puzzling thing is that there was zero residue anywhere else in the system. None. Not under the keyboard, not on the top of the board directly under the memory, nothing... Most peculiar sight.

Could it have come from the factory like that? It seems hard to believe. From what I could tell, the system hadn't been messed with at all, from what I could see.

The issue that brought it to me was the Airport Card was just dropping the network. It's on another part of the board...

Anyone else seen anything like this? It's got me stumped..

MacBook :: 'Built In Speakers' Are No Longer An Option For Audio Output

Mar 15, 2012

The speakers on my Macbook have suddenly stopped working. If you plug headphones in, fine. In the system preferences, 'built in speakers' are no longer an option for audio output. Just 'digital out'. When I try and change the volume of the speakers, the symbol is greyed out, and there's a little "you can't do this" symbol.

OS X :: How To Use Two Sound Output Devices

Apr 30, 2010

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?

Software :: Fixing No Output Devices?

Oct 23, 2002

I was with sounds problems using OS 10.2 and I decided to format my disk and make a clean install. After installing 10.2, my sound was working well. I upgraded to 10.2.1 and in the following restart when I tried to use iTunes, no sound at all. When I hit play not even the cursor moves; nothing happens. I opened the Sound control panel, and in the Outpu tab there's a message saying:
" no output devices were found"
I cannot figure out what's happening. My computer sound is OK; everything works fine when I restart using OS 9.2.2.

I am trying to copy a 650MB .mov file (shot on a Canon 5D) from a lacie rugged external harddrive to my G-Raid but it stops at 22.5mbs and then I get the error code "can't complete the operation because some data in "8T2C1814" move can't be read or written.

OS X :: Won't Found ISight / Can't Work With Apps

Mar 22, 2010

I have a Macbook pro Late 2007 with a built-in iSight (of course) and Mac OS X 10.6. Some weeks ago my iSight started to be not recognized by software like Photo Booth of Skype. As I don't use it frequently I didn't search a solution but now I miss my webcam.

Photo Booth simply show a message like "webcam not connected". I think that the problem started when i uninstalled an app which emulate a webcam from a video file. But I can't remember the name of this app.

Intel Mac :: Image Capture Does Not Have A 'Devices' Option

May 28, 2012

I have a new scanner and I installed the drivers. It's showing fine in Photoshop CS3 but the window for it is awkward and small and barely has any features to it (there is no selection to for Advanced either). I figured I should try to use Image Capture instead, hoping to have better luck and more features. However Image Capture is not allowing me to go to 'Devices > Browse Devices' because there is no 'Devices' menu listed at all. I've restarted, unplugged things, plugged devices back in. It just says 'No Camera or Scanner Selected'. the Command B is not even working either.

Windows On Mac :: No Audio Devices Found In Boot Camp Vista On New Mini

Jun 29, 2010

i'm a HUGE gamer, so the first thing I did once I loaded this new computer up was install my copy of Windows Vista on it using Boot Camp Assistant. The installation went completely smoothly, so I then proceeded to install the Boot Camp Drivers onto my new and fresh and clean Windows Installation.

I restarted the computer and everything seemed to be in working order...but there are two relatively MAJOR problems:

One, the one that is the most pressing, is the sound. When I started up after installing all of the boot camp drivers, I couldn't get a single audio device to get recognized by my Vista Home Premium installation. I tried disabling and re-disabling other drivers in the Device Manager, and when I try to download new drivers for the one audio device that has an error sign next to it, Vista claims that it is already updated to the latest drivers, so it will not install new ones. I even went onto cirrus' website to download their official drivers, and the same thing happened.
