Audio device gone on MBP 13" Lion

On boot i get: "Sound assertion "0 == pinConfigurationsProperty" failed in AppleHDACodecGeneric at line 946 goto Exit".
This happened out of the blue after sleep. Hardware failure or software issue? Want to avoid reinstall if possible.

Download the free utility App Kext Wizard, which might fix this issue.

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. I need all three for a podcast, any solutions?

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. At first I thought maybe the third microphone was just defected or something but I tested the mic individually and it works fine. It'll let me use two Blue Yeti's and another microphone but not three Yeti's at once.

Ive had 2 identical USB AT2020 mics connected at the same time on both macbook pro and macbook Air.
The "Yeti" mics, are, lets say undesirable, and low to mid computer consumer mics.

Macbook Air Audio Output Device Gone

My sound on my mid 2013 MBA has gone. Under prefeerences, there is nothing under device output. I have restarted several times; no luck. I looked under Mac HD, library, prefs, audio,; but could not find any audio files to delete as per one thread. Under utitlites went to audio midi etc, but could not find any listed audio output device list. I have repaired disk permissions. Done a shut down and restart. But still audio is greyed out, and no devices show up under system prefs, sounds, for output device. PLEASE HELP... I am in Zambia and closest apple dealer is in S.Africa. Thank you.

Go step by step and test.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure that Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. 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".
5. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

My MBP is not recognising the audio device and won't complete a time machine backup, what might it be?

I have a MBP thats about 18months old. First indicator was the audio device intermittantly being recognised ( the speaker icon on the status bar goes grey, nothing with sound works, then it comes good again). Thought little of it, till I noticed the backlighting of my keyboard also failed at the same time as the Speaker icon was grey.
Then lately, it wont do a complete time machine back up, either via airport or usb.
Its starting to sound like i have a "serious" issue, any one with clues where to start?

let us know how it goes.

MBP 17" Boot Camp Firewire Audio Devices

Hello Everyone.
If your having installation / dead audio issues with a firewire audio device in Boot Camp running Windows XP such as the Presonus Firepod or Tascam FW 1884 you should try downgrading your firewire drivers from Service Pack 2 to SP1.
As showed in this article:
http://www.rme-audio.com/english/techinfo/fw800sp2.htm
Please note I also had to rename my services pack 2 file (C:\Windows\Driver Cache\sp2.cab) to another name so windows wouldnt use it when downgrading.
Both my Firepod & Tascam now opperate as expected.
After a day of searching and crying I found (loosly) the answer in these forums.
Thanks everyone, hope this info is useful to someone else too. ^_^
Best,

Mac Book Pro 17" Mac OS X (10.4.7)

After two complete reloads of OS X, Boot Camp and installing XP Pro again both times the driver CD still fails to run.
Also I cannot update firmware at all. Running firmware updater
from utilities fails with a message that this firmware is for specific machines and does not apply to this computer. (not an exact quote)
Downloading and running the firmware update for MBPro also fails with a message that this computer does not need updating. Made sense to me since the 17" was released after Boot Camp but the "not for this computer" error when trying to run it through Firmware Updater makes me wonder...
I do see that the driver CD extracts some folders\files to the users Temp folder in Windows XP, I copied those out but have not figure out the manual install of drivers yet. In fact I don't see any drivers - just misc config files and the various script files to run the drivers application.
Going to run it again this afternoon after XP Pro reloads yet again and try looking in the Windows\Temp folder for the drivers, check everywhere to see if they actually extract.
After that it should be fairly simple to manually install them and circumvent the auto-install failure of the CD.
Will post later with results.

XP 64 Bit - Audio Device on High Definition Audio Bus - Driver needed!!

This concerns a Macbook Pro
Hi, I have followed many tutorials on the internet to help install XP 64 bit on my bootcamp partition.
I know this is not advised due to the lack of driver support but I have 8GB of RAM and want to utilise it all on my favourite OS.
Things have gone well and almost all devices have the correct drivers installed.
There is one exception to this:
I installed the RealTek drivers from the high definition setup exe and Device Manager simply tells me I have codecs installed for audio and video etc. the problem is that under 'Other Device' I have 'Audio Device on High Definition Audio Bus'
Due to this, my speakers do not function and no sound tray icon exists. I have tried many, many different drivers so far and have had no luck.
My macbook is a 2.26GHz model and I think is known as the 5,5 model of MBP.
If anybody could offer assistance it would be widely appreciated.
Thanks, Chris

I just solved the problem
The four devices are NVIDIA High Definition Audio that the driver is included in NVIDIA Display Driver installer from lenovo.
I should install Microsoft UAA High Definition Audio driver first before installing the NVIDIA Display Driver. What I did before was I installed the NVIDIA Display Driver first before installing UAA High Definition Audio driver, that's why the four NVIDIA High Definition Audio driver weren't detected, hence the drivers weren't installed.
So the solution for Windows XP SP2 users is just simply reinstall the NVIDIA Display Driver. If you install SP3, it already has the UAA Audio driver.

No audio device installed after windows vista sp2 update

New MacBook Pro Unibody Jun 2011 - No Audio Device / No Output Device Installed. Please Help.

Dear All,
I have installed OSX Lion on the 20th July 2011 and the problem started with the audio device installed. Itunes wont even play and iDVD and you tube would work without audio. I have tried everything from system diagnostic re-booting back to original snow leopard on 10.6.7 including taking it for service. The audio works intermittently when I re-start my MacBook but eventually disappears back to square one. Until restarted again.
I am still under my 90 days from purchase date and the problem is I am no longer in London where I originally purchased the MacBook from - I moved to Delhi, India with my family and they don't have geniuses here only local service/ technicians who already tried fixing the problem.
Very disappointed after spending nearly £1,600.00 for this.
I don't want to go back to the local service centre for them to restart my MacBook to prove audio device is working.
Is there any other option for me like refund or replacement?
Many Thanks
Shah

Dear Lex,
Thank you for your advice above.
I have updated latest iTunes 10.4.1(10) 64 bit.
I have updated latest OSX Lion: 10.7.1 Build 11B26
Still the problem occurs. When laptop restarts the sound stays for 5-10 min before shutting down intermittently. In iTunes the music will not even run - other applications such as YouTube - it will run but no sound.
I have tried everything now and I am certain it must be a software connected issue I am experiencing only.
Please can you help.
Many Thanks

Macbook Pro 13" (Late 2011) - High Definition Audio Device - Code 10

Hi, i installed Windows 7 Ultimate 64 Bit via Boot Camp on my new Macbook Pro 13" (Late 2011). Driver Disk was installed, but the "High Definition Audio Device" couldn't be started. Status is Code 10. Normal Cirrus Logic Audio is working. Any advice, how this could be fixed? Would be nice, to have audio over the Mini-Displayport HDMI Adapter on Windows as well (Works perfectly with Lion).
Thanks,
Thorsten

Could not find supported audio device in AA3

okay so i know its not a good idea to use AA3 with Vista...but other people are doing it so why can't I? I've seen the topic posted before but the threads are pretty much dead and I still have no helpful info. I've scoured this thing with no affective solution. I've installed AA3 on several systems in the past and never had this much trouble--if any. This problem has gone on for over 2 months now!
Since I installed AA3 on my new computer all i can get and all i have ever gotten is the "AA could not find a supported audio device. Please check device settings" dialog--
press okay (or x) and Audition closes---never getting past the loading window --during "initalizing required components"
I have 3 audio devices/ with up to date drivers which all my other audio programs recognize (Audition 1.5, Sonor, Cubase + more) with no problem whatsoever--
AA3
Windows Vista SP1 64 bit
Realtek HD Audio
+ Presonus FP10 digital firewire interface/preamp (kind of unrelated but aa3 still wont recognize it either apparently)
I have installed all updates including the 64-bit SP1 fix for AA3.
I've read the Realtek HD issue solutions and made sure my drivers are fine.
IM DESPERATE----PLEASE!!!
I'm having a recording studio built right now & AA3 is my main DAW so this is rather dire.---All the other DAW's i've tried suck compared to AA3 (with the exception of stability). hehe AA3 is always crashing on me and yet i still prefer it over other DAW's.

I put the PreSonus StudiLive 16.4.2 plus Adobe Audition 3 setup instructions into a short write-up on my blog: Live Event Multitrack Audio Capture
Here is a photo showing how to set up the Firewire channels for input and output
I hope this helps:

Macbook Air no longer recognizes external audio devices

My Macbook air's audio port recently stopped recognizing external devices such as speakers and headphones.
The external devices are functional with other devices and fully plugged in, but only the internal speakers will produce sound.
This problem happened just recently with audio devices that had been working fine with the laptop before. I did not use any
audio devices that I haven't used with the computer before. They are fully plugged in, and I've already tried twisting the head
of the cord to see if it's going bad. The headphones I tried to use work fine with my iPhone.
I've tried opening System Preferences > Sound, to select the device, but it doesn't show up in the device list.
The internal speakers work fine, and continue to work even though the headphones or external speakers are plugged in, and in
the case of the external speakers, turned on.
Does anyone know if updating my audio driver would help?
Has anyone expirienced and resolved this problem or a similar problem?
Does anyone know how I can actually get in touch with someone who works at apple without having to go in to their store, as
I don't have time to do that and wouldn't be able to leave my laptop for repair since I use it for college?
Any help would be greatly appreciated!
Thanks so much!
Update:
I've tried using "Audio MIDI Setup", the external devices do not seem to be recognized by the computer.

Because something has gone wrong. I have no way of knowing what, and without backups, you're in a very bad situation.
If you want to preserve the data on the startup drive, and it's not already backed up, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.
1. Start up from the Recovery partition, from Internet Recovery, or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
2. If Method 1 fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
3. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
4. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

USB audio device loses output connection

I use a MobilePRE USB interface and had no problems until recently. My iMac is set to never sleep but if I do not use the computer for a few hours the output from the MobilePre is gone.If I change to the driver to the internal headphone output on the Mac all is fine but in order to use the MobilePre as output I must restart, then it is fine until the next day or a few hour later.
The same time that this problem developed, about a month ago, I also noticed a low level snap or popping sound. This happens through my external speakers and is triggered by any sound activity approximately 30 seconds later. It even happens with the volume turned all the way down and sounds like a connection is being made. Like I said these two problems started about a month ago around the time Apple was sending a lot of updates. I have read a long thread on the OSX forum and know this is a pervasive problem with no solution yet. I mention it here as a curiosity as it started around the same time as the USB audio device problem. My hunch is that it has something to do with a recent update.
I don't think this is a GarageBand problem because it is the same no matter what software is outputting. I ask on this forum because there some knowledgeable audio heads here.

Has anyone sucessfully used the new Winclone 3.2 to backup and restore Bootcamp partittion with Windows 7 Ultimate on MBP with Lion 10.7.3?

Bought late 2011 MBP 17" with Bootcamp partition (Windows 7 Ultimate) and Lion OS 10.7.3
I am trying to make a backup of Bootcamp partition before I start using my laptop but it proves to be a difficult task.
I don’t have any installation disk for Windows 7 and I am afraid that, if a disaster strikes and I loose the HDD, my copy of Windows will be gone.
The only way to restore Windows partition according to what I read so far is to do the following:
• Use Windows to backup data from BootCamp Partition
• Reinstall OS Lion formatting full hard drive in the process
• Use BootCamp Assistant to create BootCamp partition
• Install Windows 7 on bootcamp partion
• Use Windows 7 to restore data from backup file created in the first step
The only problem is that I don't any image or disk to re-install Windows 7. With Windows 7 I can create only 'repair disk' (for what it is worth) or system image but according to other users it would format the whole drive including OS Lion partition when reinstalling
Winclone 3.2 seems like the answer to my prayers but would like to hear from the users if it worked for them (most imprtantly, did the restore work?).

Got the response from Winclone regarding my confusion in step 18 of the procedure to create bootcamp backup. The message displayed on the screenshot under step 18 can be ignored. It refers to creating a Windows partition using Boot Camp Assistant but in fact this partition has already been created in earlier steps using Disk Utility.
I bought Winclone 3.3 as it promises to make backup and restore of Bootcamp partition with Windows 7 on it really easy, the steps to do this task are easy and well documented, and the owner of the program was very prompt responding to my queries.
I performed the following as an insurance against disaster prior to creating Winclone image:
Since my Windows 7 came pre-installed but without any installation disk I used Windows 7 to create 'Windows 7 system image' . From what I read on forums the system image created using Windows 7 apparently can't be used to easily restore Boot Camp partition (as it wipes out OS X in the process). I created this image as a last resort backup rescue - some users reported that it can be used to recover Windows but the process is painful and involve a number of steps, swapping hard drives, and paid software to assist in the process. I did not bother to make notes on this process - thanks to Winclone I am not suppose to need this backup if everything works as promised
I also created 'Windows 7 repair disk' prior to running Winclone. Not sure what the value of it will be but again, this is something I did just in case I need it in the future
Then I installed Winclone 3.3 and created Windows 7 Ultimate Boot Camp image without any problems (on MBP running Lion 10.7.4). My Winclone image file of 150GB Windows 7 Boot Camp partition prior to installing any programs and without any data on it ended up being nearly 8GB (saved to the external USB HDD).
I have not restored and don't plan to restore the Winclone 3.3 image just to test if it works (don't want to risk loosing my perfectly well running Windows 7 in case of any disaster). So ultimately only time or experience of other users will tell me if I spent my money well buying Winclone 3.3. I know it worked for you JBLTZ so hopefully it will work for me when I need it one day.
Cheers

USB hard drive is not recognized on MBP running Lion

Hello,
I have:
- Freecom ToughDrive Pro USB hard drive
- New MBP running Lion 10.7.3
When I plug the disk in an USB port in the MBP, the light that indicates operation starts blinking but very lighltly colored and the disk is not recognized by the computer. I have put data on it using iMac Snow Leopard. I have plugged the disk into a MBP running Snow Leopard and it works. I have also tried another Lion (older MBP) and it also works.
What is wrong? How come the disk is not mounted or shown in Disk Utility. Can it be a power issue? Any ideas?
I have noticed there a lot of similar posts in the forum and none has been satisfactorily solved. Is this a mayor Lion bug? If yes, how can I downgrade to Snow Leopard?

dafnedr wrote:
Thanks for the reply.
However... how is it possible that with all other MBPs I have tried it works just fine? Has Apple lowered the power levels in recent models? The other MBP where I have tried the disk on are just over a year old, my current one is only a month old.
Are you saying that USB ports on different Apple computers are supplying different levels of power? That's psychotic! It should be a standard power level... or it should go up on newer models... not down!!!
I think I'm just gonna return this piece of scrape and get my old (one year old) MBP back... Snow Leopard was bliss compared to this... I rather go back than have to jump to a store to buy a cable to make something work that should work by default.
On the one Mac it does not work on that Mac does not put out enough power to fully power the drive. If it works on other Mac's we know that the drive works, so that question is answered. And it doesn't work on your newest Mac then there can only one answer, Not Enough Power is being put out by the USB port to fully power it.
Yes the one Mac that it is not working on has a lower USB power output. Why, I have no idea.
This is Very Common you can find posts about it on all notebook forums. Psychotic, No. Yes Mac is touted as "It Just Works" which is a flat out LIE.
Do what you think is best for you. Good Luck

Optical audio devices.....

hi~
the MBP has optical audio in/output.....
its great, its ok,
but have u seen any brand/maker of 'home theatre or speaker' out there supporting this ?
i mean, where i live, i haven't seeen any~

in addition to surround receivers and surround processors (Dolby Digital capable) having optical jacks, there are a handful of speakers that have optical jacks too.
Roland and Edirol made a few.
The Rolands are especially good speakers. On the ultra high end, there are some very very good active speakers from Genelec and Meridian (UK) that accept digital inputs, however not optical, you would have to get a format converter to go from optical to AES/EBU or SPDIF via coax to use those.
Where the surround receiver/processors will take Dolby Digital and DTS bitstream, when hooking direct to speakers, you can only do 2 channel PCM audio... no discrete surround sound. By discrete, I'm talking 5.1 or 7.1... not prologic or the other matrix audio modes. Also, any audio device that is known as a DAC (digital to analog converter) will also work.
Technically, the optical output is a Sony specific connector that uses the "toslink" or "EIAJ" standard. This is not technically "fiber optic". The old AT&T optical connector that used ST connectors used glass fiber. Toslink or EIAJ uses a plastic core non-fibre material.
