MacBook Pro :: No Sound - No Output Or Input Devices Found


I just inherited a MacBook Pro. It's a 2.53 GHz Intel Core Duo with 4 GB Ram. Unfortunately, the install DVDs were left back home. I needed to do a fresh install and I used a 10.5.6 DVD that I own to install the system. I now get no sound at all. When I go to the System Prefs/Sound folder, I don't have anything available. It just says that there are "No input or output devices available. I know that this worked - not sure how to even approach this. It is a brand new system so repairing the disc permissions wouldn't seem to make any sense. I plugged in a headphone just on the chance that a wire was loose - no change. I am downloading the latest software from Apple - not sure if that will do anything. I don't have anything other than the system installed.

2 x 3.2 GHz Quad-Core Intel Xeon

Intel Mac :: No Input Or Output Sound Devices Found
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.

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

MacBook Aluminum :: Sound Input/output Devices Not Installed?
I'm enquiring on behalf of a friend who has a macbook which has just had a new HD installed. There are no sound devices listed either in input or output of sound preferences. (I think she's running OSex10?) How can we get the mic/line input switched on so sound can be imported? I would assume these preferences would have been automatically installed?

Mac Pro :: No Sound Output Devices Found
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...

OS X :: MacBook Sound Not Working - 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.

error message in garageband = Core Audio Selected Driver not found. (-10202) In system profiler, it shows Intel High Definition Audio:

I've never used the garageband app before, but went into it and ran updates for the first time. This is around the same time the audio stopped working. It's been a few weeks now and I'm going crazy without my sound!

OS X Leopard :: 10.5.8 Update - No Sound Output Devices Found
I recently upgraded from OS X 10.5 to 10.5.8 several days ago and everything seemed fine. Yesterday I plugged my headphones into the jack to listen to a video and that worked fine, too. Today, I have no sound. I looked at System Preferences -> Sound, and it says that no output devices are found. It appears that my computer thinks it doesn't have any speakers!

Intel Mac :: All Sound Output And Input Devices Have Vanished From Computer?
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!

MacBook Pro :: Unable To Get Audio Output / No Output Devices Found
We received a few new MBP 13 / 15" at work a week ago and three of them have non-working audio. The weird thing is that the boot up chime works but in System Prefs, it says "no audio device" on my MBP 13"...?

I took it to a "genius" bar today and they had no clue. Tried booting off an external drive - same problem. I don't want to send it in for repair - its BRAND NEW! - and I'm off on a 3-week trip next week. I'm hoping its some sort of wacky driver problem (remember: the chime on boot works).

MacBook Pro :: No Sound Come Out Input/Output Source
I own a new MacBook Pro 13", 2.53 GHz, with Snow Leopard. There is (1) audio port which can be used for audio input and audio output. I have an audio input source (Xbox 360) and would like to use my MacBook Pro Speakers for sound output. In System Preferences/Sound I am able to change "Use audio port for: Sound Input". Then after turning on my Xbox 360, no sound comes out of my MacBook Pro internal speakers.

Mac Pro :: No Audio Output Devices Found
Just this evening my sound device stopped working. During booting no welcome chime anymore and no sound device detected.

What I tried thus far:

1) Booting in safe mode
2) Hardware test
3) Booting from OSX 10.6.4 (external disk) in stead of current 10.6.5
4) Booting in Windows 7 using bootcamp

MacBook Air :: No Output Devices Found - How To Detect
The other day, when I opened my MBA from sleep mode, a gray screen popped up saying that I had to restart my computer by pressing on the power button. Well, since then, I have had absolutely no sound on my computer.

When I try to use the keyboard to raise/lower the volume, a little screen pops up with a circle with a line through it. In the menu bar at the top of my screen, where my volume status should be, there is only a blank space. Additionally, in System Preferences, there are "no output devices found."

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

MacBook Aluminum :: Sound Input And Output Not Working
Last night my audio was working fine. I was going to record some stuff in garage band and had a microphone plugged into the input line-in on my macbook. everything was working fine still, turned on the "auto leveling" and then put in my headphones. i then turned on the "monitor" to get the sound to actually come to my headphones. I didnt realize until after it was done but you cant have the auto level and monitor on at the same time. There was a short blast of sound in the headphones and then everything cut out. I couldnt get sound from anything, headphones, built in speakers. No sound going in either.
I restarted my computer and if I remember correctly (maybe i'm imagining it) there was the start up chime. when I started up garageband again I got an error message reading "selected driver not found. error 10202" still no sound input or output. When trying to adjust the volume all I got was the grayed out volume thing with the little cross thingy at the bottom. I checked the sound settings and there was nothing in the input or output sound.

I did some searching around and saw people with similar problems (none with an answer).

This is what I've already tried:

I reset the permissions

I reset the PRAM

I did a hardware check (hold d which restarting) i even did the hour long check and there was no problems.

I tried putting headphones in an out (there was no red light in the headphone jack)

I updated all my software (there was an update to OS X to 10.5.8)

After the update there was no longer a startup chime, and i got no error messages when opening garage band. however there was still no input or output sound. when adjusting the volume on the screen it appears to be normal, but there is still no sound from built in speakers or headphones. I did notice there was a very faint "clicking" noise when i try and adjust the volume... like the speakers are getting power or something... but then nothing comes out. In the sound settings there everything appears to be back to normal.

I wonder if there is any way to choose separate audio devices for audio input and output? I want to use one device for recording audio, and another one for playing it.

'No Output Devices Found' MacBook Air
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.

OS X :: How To Use Two Sound Output Devices
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?
