ISight makes croaking sounds and produces audio dropouts in recordings

Hi!
This is weird and hopefully not normal?!?
My new iSight made these short cracking sounds (kind of like scratching over sheet of paper) from the beginning.
Once when starting up the Mac and all along during video recording or conferencing.
That alone wouldn't be such a big problem but audio is very weak too, since it produces drop-outs and other weird noise especially during conferencing or even just during skype phoning (no video).
While trying to record that sound (iMic) I found out that its not possible because other Audio In dropped out too, while iSight is croaking :-S
Of course I tried out everything I could and the problem is still there even when the iSight is the only peripheral (USB and FW) on my G5.
ISight is the perfect webcam and makes awesome picture and sound quality besides the mentioned issues. Hopefully I don't have to send it back.
Thanks for your help buddies!

How to test your iSight to ensure it is functional should help you find out whether you need to have your new iSight repaired or exchanged under warranty.
If your G5 is otherwise reliable and stable, because you are having the same problem with your iSight when driven by different apps, your iSight, iSight's connecting cable, or your G5s firewire or connections would seem to be the most likely suspects.

How come when i try to edit my imovie project, it just makes a sound and wont let me close out of the project?

Ive been editing a video on imovie, and it was working fine but now when i try and click on anything it just makes a sound and wont let me edit or close out of anything. I dont want to force quit because then ill lose my project. is there ant other way?

Because you closed the main window before saving. Hit cmd-1 to get it back.

I have a stuck CDR disk in my MacBook. I have tried everything and nothing works. When the computer starts it makes weird sounds and also when I try to eject it. Nothing Works! Please Help.

I have tried everything and nothing works. When the computer starts it makes weird sounds and also when I try to eject it. Nothing Works! Please Help.

I had that happen with a MacBook. It turned out that the metal case above the slot was slightly bent down.
Putting a flat blade screwdriver in the slot and gently twisting it to move the metal case up allowed it to eject. Don't put it in too far you only want to bend the case not the drive.
The case can get bent down by picking it up with your thumb pressing down on the case above the slot.

*FIXED* No sound and 'No Audio Device' in Control Panel. *FIX

I?m having a problem with my sound. Basically all I get is a system sound, which means no sounds from itunes but the error prompt sounds still play. I?m tempted to say that this is a detection issue because of several things:
-First, when looking in the ?sounds and audio devices? in the control panel I get grayed out selections and a ?no audio device?.
-Secondly, when running the directX diagnostic tool (typing ?dxdiag? in the ?run? window) I get several troubling indications. First under device I have no manufacturer or product ID. Second under drivers I have (copied from dxdiag text file):

Seems hunky-doorey but then I have a note at the bottom that reads:
Sound Test Result: Failure at step 3 (DirectSoundCreate): HRESULT = 0x88780078 (No driver)
I have seen another similar post that seemed to have the same problem, but they didn?t provide much information and the fix was to pull out the audio card, run start up, turn it off, and then put it back in and run start up. If this is what needs to be done, could I have a picture or something of what the sound card looks like?
This problem started when I tried to update my sound card and since then my sound has been? possessed? or prone to working at sometimes and then (most of the time)failing at others.
Here is the dxdiag.txt file without the lengthy directShow filters and directx components:

I found that once you reinstall your sound card you need to make sure you hook everything back up correctly.
basically all you need to do is run a start up with your sound card out ofyou computer and then re-run start up with the card back in.

No sound and no audio card in device manager

Hello!
I have a HP Pavilion dv6710ea and my operating system is 32-bit Windows Vista SP2. Quite some time ago my optical CD/DVD drive stopped working. It simply disappeared from My Computer and the Device Manager. I've tried all the suggested fixes I found on this forum but none of them worked. But I didn't need the drive that much anyway, so after some struggle I just gave up on this issue.
And now another such thing happened. Suddenly, I lost sound and when I hovered my mouse pointer over the sound icon at the taskbar, a pop-up showed saying "No Audio Output device is installed.". I checked the device manager, and my audio card was gone! Any attempts to detect it failed. I restored the system to the point before the problem occured, but it did not help. I tried to install the new audio drivers, but the installation failed, because the device could not have been found. Now I don't know what else can be done to try to fix this. I certainly hope it is not related with hardware failure of some kind.
I would greatly appreciate any help on this issue.

Hi,
Reset BIOS to defaults
Restart the PC, as you see initial POST Screen on the Monitor, start pressing F10 to access BIOS< press f5, select Yes, and Press f10 to save and exit.
Download and install Audio Driver.
Thank You.

Mac Book Pro starts up to white screen then makes a sound and dies, turning off

Hello, my macbook pro is new, bought in August 2011. Just recently my battery died prematurely after only 118 cycles. However, the hard drive also had to be replaced as it wasn't for some reason working with the battery. Now, my computer even though the battery works and I've passed all my documents to the new hard drive is having problems when it starts up. It makes the typical apple sound when it turns on and it goes to the white apple screen and unexpectedly dies off (turns off). It makes a sound as if everything is starting off then a dying sound when it turns off. Sometimes I try it again and it turns off or it can also turn on randomly and fully boot. Holding the shift, control and alt key while it is connected to the battery until the charge changed color works but it is not a permanent solution as this problem has continued for a week. It occured a couple of days after replacing the hard drive and battery at the genius bar. Any help?

It is better to take it back to the genius bar.
Your MBP is under warranty and let them fix it for you.

Imac G5 20" makes startup sound, and fan kicks in, but screen stays black

Hello. I have read the many similar postings and tried alot of ideas with no luck. Here are the specs on the model:
G5 20"/2.0/512mb/250gb/Super/56k/BT/AP EMC2056 Model A1076
When you push the power button, you get the bootup sound, and the fan turns on. Then 30 seconds later, the fan goes into hyperdrive. The whole time the screen stays black. I have tried resetting the pram, get no sound then. I have tried the internal startup button below the fan housing, and it does NOT have the 2nd button there as it is an ambient light model. So I held the power button and plugged in the power cord, still nothing. When plugged in, the 1st green light lights up on logic board. When I hit the power, the 2nd green light lights up. I have tried an external monitor with the adapter plug and still no picture. I do not even hear the hardrive try to read. Could it be a power supply? What are the other 2 lights on the logic board for, as there are a total of 4? I have not tried to boot from a cd or change the battery yet. I don't know if there is a point in doing that, as the screen remains black. I cannot use a conventional pc power supply tester either. Any other ideas on this situation?

"Could it be a power supply?"
More than likely if everything else possible has been ruled out. Your model G5 had an extension repair program which has long expired for your exact issue. Shame you missed it.
"I have not tried to boot from a cd or change the battery yet. I don't know if there is a point in doing that, as the screen remains black."
You won't know if it will do any good until you at least give it try. You should also run Apple's Hardware Test from the Install DVD #1. The DVD label will tell you which key to boot up from to run the AHT.

Delayed system sounds and no audio in web browser or itunes

HP Envy 14 B4B15UA#ABA Windows 7
No changes to the system recently (that I'm aware of). Suddenly I have no sound in iTunes or Chrome. The volume equalizer doesn't show anything when sounds should be playing, and iTunes doesn't even try to play. Also, system sounds are on about a seven second delay. When I try to configure my speakers, I get an error that says "failed to play test tone", but then it plays several seconds later. System "clicks" and error tones are also delayed.
I have tried searching for audio driver updates (IDT High Definition Audio CODEC), but it is current. I have tried plugging headphones in, no dice. I have restarted several times, and installed windows updates. I have restored system defaults in case I accidentally changed something. I even went into the godforsaken Beats controller to see if something was wonky there. Nothing. I have no idea why this is happening. Please help.

Hey thatpurpleone,
I see that you're not getting any sound from the speakers.
Follow this Document even though you mention there wasn't nothing that changed with the system.

The harddrive makes weird sound and is dead!

Hi
I bought this fancy car stereo with a aux input so I could listen to my iPod in the car. Whoever had the car before me had a magnet attached to the dashboard, for holding onto her cellphone. Well I looked at my iPod, I saw a metal cover and figured it would be perfect to have it on that magnet. Well, 2-3 trips later my iPod won't play anymore and when I try to turn it on it makes this weird sound as if something is scratcing in it, internally. Then that white screen comes up with a sad iPod-smilie. When I plug it to the computer it just keeps trying to start up, repeatedly.
Have I destroyed my baby?
This *****.

yup. its dead. this just happened to mine, oh, a couple weeks ago. its probably not due to the magnet, though. when i took mine in they said it was most likely because of some kind of physical trauma the ipod had been through, sudden or over time, such as dropping or just being moved around a lot. if your ipod is under warranty, though, you shouldnt have any trouble getting a good-as-new replacement at the store. when i went there was a pretty long wait, but once i got there it proceeded very quickly. i must say, i expected some kind of long ordeal, but all that happened was i showed him the noise it was making and the sad ipod icon, he said "ok", did something on his computer real quick, and went into the back and got me a replacement. if your ipod isnt under warranty anymore i suggest reading whatever information you have on ipod support(i dont know if you saved the little booklets in the box or not, i did). i read it all before i went in, and most of it is just protecting themselves in case they treat you like crap(which may have been the reason i expected them to), so i wouldnt get your hopes up too much if your ipod is no longer in warranty.
good luck

PXIE-1065 Chassis makes clicking sound and will not power up.

Came in from the weekend to my few week old PXIe-1065 chassis making a clicking sound near the ac power cord and it will not power on. I removed all the cards from the chassis and it stops clicking, but as soon as I replace the controller (PXIe-8133) it starts clicking again. Is this an ac power supply failure in the chassis. I also noticed there was no filter elements over the fans in the rear of the chassis like my smaller (PXIe-1082) chassis. Could this have led to the failure?
-Jeremy

Hi uyt,
There are a few troubleshooting steps to take here that might show where the problem lies. Have you tried any other embedded controllers in the control slot of this chassis? Do they show the same behavior? Have you tried that controller in your other chassis? Depending on which one the issue follows, I would be inclined to guess that part is damaged in some way and needs to be RMAed.
In response to your suspicion: I would be extremely surprised if you were delivered a part without a physical component and many of our newer chassis do not have the fan filter you are referring to, so that is likely not the issue.
Feel free to call in to our support line at 866-275-6964 to troubleshoot the system with one of our engineers before RMAing the device.

I get random buzz, skips and or audio dropouts M-Audio issue??

I'm trying to record my live DJ sets through my M-Audio box into Logic 8. Randomly i would get a buzz noise for a split second randomly through out the mix.
Things I've done to help eliminate this:
1. Reinstall New Mac 10.4.11 Pro Update.
2. Reinstall M-Audio Update
3. Removed all my external Hard Drives (this helped to remove 90% of the noises,
but they are still there.
Anything else I can do to help my recording go smoothly?

You're probabely running with a very small audio buffer. Removing you're external disks has sped up things a little but it seems your mac just can't keep up with the data. Try enlarging the audio buffer in the audio settings dialogue.

When I put my 4th gen iPod Touch in my iPod dock it makes the sound and charges but when I play music it is silent. Help?

The volume slider at the bottom disappears, so it is connected and my iPod dock will play music on my old 4th Gen iPod Touch. My new iPod will play fine through headphones, the internal speaker and one other iPod dock I have tried. I have restarted it (home and lock keys), reset and backed it up and this problem existed when it was on iOS6 (have updated it to iOS6.1 - problem still exists). Any help or suggestions welcome!!

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
However, sometimes an iOS update will break conpatibility and you will have to wair for an update to either the iOS or the dock firmware.

IChat audio dropout

I have never experienced any issues with iChat untill recently updating to 10.5.8. I am running on a Macbook Pro 2.2ghz with 4gb ram and the issue is basically when video chatting when the conversation initially starts I can hear everybody fine and they can hear me. Then about 2-3 minutes into the chat there is a high pitched sound and my audio drops out? I can still hear everybody else but mine is gone untill I reboot iChat and then it happens all over again. Anyone come across this? I tried restarting the Mac but it still was a problem. I am not sure what to do here...should I trash the ichat prefs?
Let me know your thoughts

Hi,
What else is your Mac doing particularly at the interval you list ?

Sound and Vibration Spectral map not working in LabVIEW 2011

I recently installed the latest development suite with LabVIEW 2011 and sound and vibration toolkit.
Previously I have successfully used the express function "spectral map" without a speed profile for plot type "frequency-time". With the installation of LV2011 I get an error saying "OA Speed Profile attribute not found" when using the function.
The setup is pretty straight forward with express functions "Simulate Signals", "Spectral Map" and "Color Map" in series.
Is there a bug fix or workaround for this problem?

No, I haven't been able to make the Sound and Vibration Spectral Map express node work in LabVIEW 2011.
A workaround is to not use the express function for a spectral map. You can find the spectral map node under "Sound and Vibration"-"Order Analysis"-"Spectral Map".
I guess the speed profile should be the same for both the express and ordinary function. If so you need to input a cluster of 2 1D arrays, not a waveform. Array1 contains the time in seconds and Array2 the associated speed.

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. any soln ?

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing wireless network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. I am using a set of speakers from kenwood connected to the airport express. The operating system on my macbook is mac os X 10.5.8. i am sure it is not a problem of streaming music online because i have even tried playing music which are stored in my macbook.
Is there any problem with the setting in itunes or quicktime ? Kindly reply...... I am waiting for your valuable suggestion.
Thank you a lot in advance.

I am shocked to have found this same AX audio dropout problem starting TODAY, every few seconds the audio just drops for a couple seconds and then resumes: Latest software versions of everything. No iPad, iPhone or Touch. Internet hardwired to D-Link DES1105 (1000baseT Switch) hardwired to new 80211N AX, AX optical to stereo, AX Wi-Fi internet to basic 1st-gen MacBook operating at 80211G, and an older 'G' AX extender at the far end of the house, away from all this. The MacBook streaming iTunes is usually 12 feet from AX. I've used this setup for years of trouble-free AirTunes / Airplay until today. Today I also found 2 very reliable fixes and 1 way to force a dropout, but first, I read some posts and tried ALL following settings one-at-a-time and restored them ALL because NONE of them helped: Turned off IPV6. Streamed to multiple speakers 'Computer' and 'AX' (restored to just AX). Turned off 'Ask to Join new (WiFi) Networks'. Turned off Bluetooth (can't live without Magic Trackpad, so glad that wasn't it). Here's my discoveries: Lo and behold, each time I click the Airport icon in the Menu (you know it shows you've got 4 bars from AX) when the status switches to 'Looking for Networks' for a second it CAUSES the AX audio to drop out for a couple seconds (it never did that before today.) iTunes still playing, streaming, AX laser still lit, but the 'PCM' light on stereo and the sound GOES OUT EVERY time I click the Airport icon in the menubar, just like the regular, annoying dropouts. So, to reduce traffic I quit Safari (3 tabs, no streaming, just Gmail, Google, and Netflix browsing). Lo and behold, the dropouts stopped altogether. No other Web apps going (not iTunes Store, Genius, Ping, nothing), so I launched Chrome to the same 3 tabs and the dropouts HAVE NOT RETURNED. That's right, not only did simply QUITTING SAFARI cure it, and Chrome doesn't contribute to it, but I can demonstrate it just by forcing my Airport to re-scan. Works for me, written using Chrome. The other reliable fix is to hardwire MacBook to the Switch. This is obviously not ideal, but Airplay audio doesn't drop out over Ethernet. Also, in all my tests, it made no difference whether iTunes did the streaming, or Airfoil did.
