No Sound & No Sound Devices & iSight always on

So I think this a tough one.. so here we go:
I have a mid 2009 13" Macbook Pro.
http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-2-duo-2 .26-aluminum-13-mid-2009-sd-firewire-800-unibody-specs.html
I had Leopard on it the whole time until I decided to upgrade both the RAM and the OS to Mountain Lion. I grabbed these from amazon http://www.amazon.com/gp/product/B001MX5YWI/ref=oh_details_o00_s00_i04
did the RAM upgrade and things looked fast.
I did the whole Snow Leopard upgrade afterwards first and then ML. After that, the sound went away and the iSight green light remained on all the time. The camera works if I open Photo Booth though.. But my biggest concern is my sound..
Pressing the keyboard keys for volume just gives a crossed out speaker volume. The speaker in the menu bar is just grayed out.
So here's what I've tried so far:
I've rebooted several times.- Nothing
I've reset the SMC several times.- Nothing
I've reset the PRAM and the NVRAM a couple of times ... hate having to redo the setting again.- Nothing
I've reinstalled Mountain Lion. - Nothing
I've reformatted the hard drive and downgraded to Snow Leopard, updated SL and while in Snow Leopard, I've rebooted several times, did SMC resets, PRAMS and NVRAMS resets.
The whole time I have not noticed any red light on in the headphone jack.
I have jiggled around with it by putting multiple head phones in and out.. as described by other users. - Nothing
In Audio Midi setup, I see no devices. So my mic does not work as well.
I've download this firmware update here: http://support.apple.com/kb/TA24826?viewlocale=en_US -Nothing
During this whole process, my iSight light is still on.
Is there anything else I missed? Thanks for your help..

It's broken and needs to go to Apple to be fixed. that will cost you as the Logic board will more then likely need to be replaced.

Plug-in and Removal of sound devices

Hi,
We're having a problem with USB sound devices. When our application is running, we can't determine if the user has plugged in or removed a sound device. After the first call to AudioSystem.getMixerInfo(), it always returns the same list of devices.
Is there any way to get the list of devices that are currently available?
Here is some example code to illustrate the problem:
import java.io.IOException;
import java.util.List;
import java.util.Vector;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Line;
import javax.sound.sampled.Mixer;
import javax.sound.sampled.SourceDataLine;
import javax.sound.sampled.TargetDataLine;
public class DeviceEnumerator {
    private static List<String> enumerateDevices(Class<?> lineClass) {
        List<String> ret = new Vector<String>();
        for (Mixer.Info mixerInfo : AudioSystem.getMixerInfo()) {
            Mixer mixer = AudioSystem.getMixer(mixerInfo);
            Line.Info lineInfo = new Line.Info(lineClass);
            if (mixer.isLineSupported(lineInfo)) {
                ret.add(mixer.getMixerInfo().getName());
        return ret;
    private static List<String> enumeratePlaybackDevices() {
        return enumerateDevices(SourceDataLine.class);
    private static List<String> enumerateCaptureDevices() {
        return enumerateDevices(TargetDataLine.class);
    private static void findAudioDevices() {
        List<String> playbackDevices = enumeratePlaybackDevices(), captureDevices = enumerateCaptureDevices();
        System.out.println("Found " + playbackDevices.size() + " playback devices:");
        for (String s : playbackDevices) {
            System.out.println(" " + s);
        System.out.println();
        System.out.println("Found " + captureDevices.size() + " capture devices:");
        for (String s : captureDevices) {
            System.out.println(" " + s);
        System.out.println();
    public static void main(String[] args) {
        System.out.println("Press Enter to start ...");
        try {
            System.in.read();
        } catch (IOException e) {
            e.printStackTrace();
        while (true) {
            findAudioDevices();
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                break;
}

Sound device problem in ZONE

I created a solaris zone for my desktop use, but the sound device was not avaialbe. I tried to export it from the global zone:
device
match: /dev/sound/*
then rebooted the zone, login it, found there were several files added in /dev:
lrwxrwxrwx   1 root     root           7 Sep 17 14:50 /dev/audio -> sound/0
lrwxrwxrwx   1 root     root          10 Sep 17 14:50 /dev/audioctl -> sound/0ctl
crw-------   1 root     root      34, 0 Sep 17 14:50 /dev/sound/0
crw------- 1 root     root      34, 1 Sep 17 14:50 /dev/sound/0ctlThe problem is: how to change the /dev/sound/* files for all users to read and write, permanently?
I tried the following methods but failed:
1. Change manually these files' mode to a+rw as root. But once I logged out the zone or rebooted the zone, the changes were lost.
2. Create a script in /etc/init.d/ and link it to /etc/rc3.d/ to let it auto execcute when boot, as below:
#!/sbin/sh
/usr/bin/chmod a+rw /dev/sound/*
echo `date '+%D %H:%M:%S' > /var/tmp/enable.audio.log
ls -le /dev/sound/* >> /var/tmp/enable.audio.logthe content of /var/tmp/enable.audio.log is something like:
crw-rw-rw-   1 root     root      34, 0 9月 17 14:50:30 2005 /dev/sound/0
crw-rw-rw-   1 root     root      34, 1 9月 17 14:50:30 2005 /dev/sound/0ctlBut oddly, the permissions of these files would always be changed back to the original state soon, automatically.
3. I added an entry in /var/spool/cron/crontabs/root to change the permissions every 10 mins, and it did work, strangely. However I think it's not a good method, because I have to wait for 10 minutes before I can login it (if I login the zone before the permissions were changed, the sound device will never work)
Thanks in advance.

It's probably /etc/logindevperm that's fighting you. Read the comments in that file, then you can modify /dev/sound in it.
The idea is that only the user logged in on the console would normally have access to the audio device and the frame buffer, so the permissions are reset at login.
If you're having folks login through a separate zone, this changes that assumption.

Find the right sound device in /dev

Hello guys,
I want to set the right sound device to record also sound from my internal microphone with xvidcap. For that I have to set the proper sound device /dev/XXX in the settings of xvidcap.
But how can I find out which of them is my internal microphone?
Regards

Looking at this old thread from 2011 I know others will look for an answer (I was doing just that a week ago). Yes xvidcap is old but it does work and does record sound as well. Here is what helped me to get it to record sound:
For the common no-sound problem:
1. Install pavucontrol and alacarte if not already
2. Open the program with padsp xvidcap
3. Click on the recording button (red circle)
4. Run pavucontrol, go to the Recording tab and there choose Monitor of Analog Stereo Internal Audio
Done!!
To record with sound, the program has always to be run with padsp xvidcap (for example from ALT+F2). To run it always like that from the menu: run alacarte, go to Sound and video, then to XVidCap Screen Capture, Properties and where it says Command put padsp xvidcap.
The stated is to record the system sound, that is, the one coming out of the speakers, that can be of a song or movie of our hard drive or pendrive played by Totem, of a Flash music video of a website played by Firefox, ...
Nevertheless, sometimes it can be necessary to record the microphone sound, for example if we want to make a video tutorial to explain how a program works. In this case we put xvidcap in recording state, run pavucontrol and in the Recording tab we put Analog Stereo Internal Audio (without "Monitor of" ahead).
If we only want to record sound (without video) we can run from ALT+F2 gnome-sound-recorder. The first time probably it will be configured to record from the microphone. To record the system sound we run with ALT+F2 gnome-volume-control, go to the Hardware tab and in Profile we put Analog Stereo Output (it's also possible to do this running pavucontrol and using the Configuration tab).
But when we finish we have to put again Analog Stereo Duplex in the Profile of Hardware of gnome-volume-control (or of Configuration of pavucontrol), so we can still choose the origin of the sound when recording with xvidcap.
Another option, not to have to change once and again between Analog Stereo Duplex and Analog Stereo Output neither limit the sound source for xvidcap, is to leave Analog Stereo Duplex and use also gnome-sound-recorder with padsp ahead, that is, run padsp gnome-sound-recorder. Like the stated for padsp xvidcap, to change where we want to record the sound from, we put the program recording, open pavucontrol and in the Recording tab we put the desired option. We also can change the menu entry if we want with alacarte, going to Sound & video, then to Sound Recorder and then to Properties.
NB: sometimes, to change from Analog Stereo Duplex to Analog Stereo Output it may be necessary to change first to Off, close, open again and then change finally to Analog Stereo Output. The same for the opposite change. If not, the computer may "not notice" that we have applied the change.

Losing Sound Device Settings

Every couple of weeks or so, when turning on my PowerBook, or restarting, my sound device settings are lost, and I have to restart using the reset pram rule.
I'm current on all of my updates, running 10.5.5, and my PBK is a 2005, pre-intel. Anyone have an idea why i'm losing my sound device settngs? Internal boot battery getting low perhaps?
Also, I have an odd sound issue. Every once in awhile, I'll hear a what sounds like a static pop through my external speakers. Haven't heard it as far as I can remember through the internal speakers, only when the externals are plugged in. My external speakers are Altec Lansings with a sub.
I just heard the "pop" as I'm writing this, and haven't rebooted yet, so don't have my device settings activated yet. I guess my next stop is the Altec forums!
Thanks for any help.

My MBP always has a pop before a sound, if it has been idle for a while. This has been reported before. It seems that when the digital sound system "wakes up" it makes a pop sound. That is normal but not really acceptable.
However, the pop you hear could be something else, and could be, in fact, the sound turning off.
Run the Audio/Midi setup app and look at what the input and output options are when the sound is lost.
You can also run the Sound Preference and see similar things.
Does your notebook have a second battery for storing PRAM/NV-RAM data? I know some older units did. If so, it may be dying and you are losing your settings.

My sound device does not work after yesterdays update

after the last update my sound device is out of system.

Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.

Lost sound devices now blue screen of death when updating creative drivers.

I have an XPS with windows 7, dont k now what the sound card is, I have factory installed software for Creative X something extreme, and Realtex.
Now I had been trying to get sound via an optical cable to an AV amp with no success. I had tried disabling and re enabling sound devices, then I tried updating the drivers, realtex was ok but the Creative drivers caused the blue screen of death with the message IRQL Not less or equal"
I tried all options in device manager including rollback, every time I try anything I get that blue screen of death, whats more, in "Sounds" in the control panel, I have lost two of my sound device options that do not appear even with "show hidden devices" so I now have no sound.

Hi Nambo,
Device manager should list the exact hardware in your desktop. But normally, integrated audio jacks will appear on the same backplane as other motherboard components, while an add-on card will have its jacks in an expansion slot. So you should know whether you have integrated or add-on.

Premiere Pro CS6 does not recognize USB PnP Sound device connected to iMac OSX even when activated in Audio MIDI setup. The iMac(i-7 processor,16 GB) is working with this USB device without any problem

Premiere Pro CS6 does not recognize the USB PnP Sound device in order to produce a commentary sound track. The USB device has been activated on the iMac OSX by using the Audio-MIDI-setup and is working correctly with the iMac. When opening > presets >audio hardware I can only select between >standard >out integrated > digital input integrated >microphone integrated. USB PnP is not indicated at this place.
With the built-in microphone of the iMac I can produce the commentary sound track, but I would prefer a stand alone version for better quality.
Your help is highly appreciated. Thanks in advance, Annemarie!

I'm using a Logitech Webcam Pro 9000 (which has a microphone on the side). I have several other devices plugged into separate USB slots: a keyboard, a mouse, my iPhone, and a Roland keyboard midi controller.
I've considered that maybe the webcam/mic combo is the culprit. If USB doesn't work at a constant speed, that could very well be causing the issue! The sound begins to lag badly sometimes when it's working properly, so that there's a multisecond delay between speaking and hearing my voice repeated back over the mic which is another sign that something is wrong. I've also caught it making a strange electronic sound during its "hang" time once it stops taking sound input correctly.
Maybe I should try to use line-in and forgo USB altogether then. I think I'd need a preamp and some sort of converter for that since the Mac Mini lacks a powered mic jack. I'm only a newbie musician so I've never set up such a system but it might be a better solution in the long run.
I'll check to see if it hangs before or after my computer enters suspend mode, that's a good suggestion too. Thank you for your help!

Issues with External Sound Devices & others - 13" Late 2011

Good day community,
Out of curiosity, I run Diablo 3 on OS X and its been unplayable since ROS expansion, massive fps drops and crashes, Blizzard claims Apple stopped improving hd3000 drivers on 10.8.3, is this true? Also when I run the game through windows via bootcamp it performs better and doesn't not crash, is this related to hd3000 driver support still being improved in windows?
Other issues I'm experiencing, facetime most of the time fails if I try to pickup a call from the macbook, sometimes it notifies me of the incoming call (iphone 5s) sometimes it doesn't. Bluetooth doesn't work, not even with apple devices, I can't pair any of them. External sound devices such as m-audio fast track pro, native instruments audio 8 dj, allen & heath xone 4d, they all have latency issues and sound clips and pops, even with the onboard sound I experience this if I open a couple graphic editing software while playing itunes. Checked sample rate in audio/midi setup, drivers, firmware, everything seems up to date, I'm not using a USB hub, I updated to Yosemite from Mavericks, which was a terrible upgrade from Mountain Lion and it completely lagged the computer, so when I upgraded to Yosemite I ran disk utility from boot and apparently repaired the hard drive successfully. Performance is better but none of the above issues were solved.
So I'm thinking about formatting from scratch but wanted to drop a line here and see if others have any of these issues and/or some tips.
Thank you for your time.

Hi Lyndon4321,
I know that can be frustrating when using an external display, but take a look at the article below to continue troubleshooting. I would take a look at Reset the system and work you way down.

Default Sound device with attached USB devices

Hi,
my situation: i've got an iMac 27" with an attached 24" cinema display (using display port and usb). Also i've plugged in a usb headset (headphone with microphone).
Whenever booting up Mac OSX 10.6.4 (also happened to older version of Mac OSX, at least all 10.6.x versions) OSX sets the default audio device (input, output and system sounds) to the cinema displays audio device. No matter what i choose as the default sound device i have to reset it after every boot.
Does anyone know how to come around this? I know i can easily set the device by alt clicking on the speaker symbol in the menu, i know there are tools out there like SoundSource that let me even more easily set the sound device but all i want to have is a default sound device that doesn't get overridden on every boot.
Any help?

All right, I seem to have solved it. The fact that it was only working using plughw: should have tipped me off, but at any rate, this is my working ~/.asoundrc:
pcm.!default {
type plug
slave {
pcm "hw:1,0"
ctl.!default {
type hw

Wengo; Skype! No working sound device

Hi!
I tried to use wengo phone and skype on my PC but whenever I want to make a call or receive a call I can not hear anything and my mic also doesn't work. Does anyone know what the problem might be? Is it because of the old OSS? I thought wengo already uses alsa (I'm using the Beta version 2)? The sound device works fine when playing music and stuff.... it just won't work using the VoIP software!
Any ideas?
Thanks!

Yes, I already installed skype-hijacker and it didn't work.
It seems that I cannot record things in general. But I already checked my settings in KMix and the mic is activated for recording. I also can hear that it's activated when testing it. I don't know why it doesn't work from within the applications.
I also cannot hear anybody in Skype or Wengophone but listening to music is not a big deal (I don't do this the same time, VoIP and listening to music so the apps don't have to share any ressource)....
What else could it be?

OS X 10.6 Sound Device Labels

I have one little annoying issue with sound devices on my Mac Mini. I have external amp and speakers hooked up to the audio out, and I have a Plantronics USB headset. When I go to select output devices, the audio out port is called "Headphones", while the USB Plantronics adapter is called "C-Media USB Audio Device"
This confuses my wife and kids when selecting what sound device to use. Can the devices be re-labeled in OSX, so the "Headphones" output device is called "External Speakers" and the USB device Just called "Headset"?

AFAIK the name of an audio device is hard-coded in the device itself, and so not alterable.

Sound device selection

a feature i would like is for sound device selection. i have my pc connected to a usb headphone audio device and my surround amp through onboard soundcard. having to go into windows sound settings and change the default sound device through control panel is a slow task. thus changing all programs that do not handle sound device selection to operate on the windows default sound device and then needing to change it over and over. simply changing the sound device within firefox then starting the audio/video playback will initiate the new sound device.

Hi,
Unfortunately as we forum-dwellers aren't Mozilla employees ( for the most part ) we can't do this for you. Try contacting Mozilla for feature requests.
Sorry about that!

External sound device stuttering

I have an imac (2011) i believe. I own an an external usb sound device, specifically a lexicon alpha. It has been working fine but recently it started to stutter when i try to playback. My internal sound is fine and I tried the lexicon alpha on a pc and it worked fine. Do I have a corrupt file or something?

usb sound devices are usb audio cards and audio cards require drivers
and if the device have a poorly written osx driver then that would happen
I would look into what audio chip lexicon use and check if I could use a driver
from another usb sound card using the same audio chip

Sound device deleted by mistake

my sound device i think has been deleted by mistake, how do i go about reinstalling it so i can play music files etc? is there an online download i can use?
thank you!!

Hello
Usually after restart the sound card should be detected and installed automatically. If you start the unit what happen in device manager?
The sound card should be listed again.
