Imac 20inch Aluminum Audio Problem

Hi, not sure if this has been answered, Didn't know what to search for. Ive had my Imac for almost a year now. Since I've gotten it I have been using a set of Logitech speakers. Recently they started to skip... or stutter. Ive found that if I wiggle the plug in the jack on the back of the Imac, I can get audio back, or make it go away. The internal speakers do not switch on when this happens, but when I try to adjust volume it is just grayed out, same thing in audio settings. Im not sure if maybe there is a way to clean the port, perhaps its dirty? The red light is not stuck on btw. Any help would be greatly appreciated. Thanks in advance.

Welcome to Apple Discussions
Are you using the correct adapter for the iMac's headphone jack? The plugin should be a 3.5mm stereo jack, does your's look like the one in the link below?
Right click then open link -> Twin Phono to 3.5mm Stereo Jack Lead

2013 iMac 27" facetime audio problem

Just setup my new iMac 27" and tried a Facetime call to a friend. He can see me, I can see and hear him, but he cannot hear me. I checked to make sure that my Sound settings are using the Internal Mic input and I am seeing a mic signal register. I also used a recording program to record some audio frorm the internal mic and it works fine. Any ideas why my iMac mic signal is not being transmitted over Facetime? Thanks for any help.
Randy

I know the camera can only be used by one thing at one time (e.g facetime/skype) so maybe the microphone on the new model is similar? So when you are using it on another program it blocks it over facetime.
Not fully sure, but it could be why.

IMac 2007 with audio problems after mavericks installation

Hi all,
I'm having some troubles since I updated my iMac (mid 2007) to Mavericks.
After the successfull installation of Mavericks I don't get any audio from my iMac. Regardless if I try to hear some music or system sounds.
Everytime you would expect a system sound (for example incoming mail) the speakers will start to buzz instead of the expected system sound.
This also happens during the system boot. I tried to reset the PRAM but without success. I also tried to check MIDI settings but this also didn't help.
Before Mavericks everything worked fine...
Does anyone have an idea or do I have to go to an Apple Store?
Many thanks and kind regards.

Have you tried a PRAM reset - might help: http://support.apple.com/kb/ht1379

Audio problem with one episode of iTunes tv show on two apple tvs but audio works fine on same show on iMac

I have a season pass to Dr Who and all 30+ other shows purchased on iTunes work great. Last night's episode (Hide) has a hissing sound so loud it drowns out all the audio in the show when i try to watch it on my Apple TV. I then downloaded the episode to my iMac and my iPad and no audio issues there. However when I tried playing it shared from my iMac to the Apple TV and the audio problem was there again. Same thing happened when I tried to AirPlay from my iPad to Apple TV.
I have two Apple TVs. One is latest model w latest upgrade, the other is generation before without latest upgrade. Same audio issue on both. I have tons of iTunes TV shows and movies and this is the only episode with an issue. Something is wrong with this file that causes it to screws up the audio on Apple TV.
Has anyone else seen this kind of audio issue specific to just one TV episode or movie? Anyone know support path for iTunes problems?

If other episodes play Dolby Digital fine this could be a file encoding problem - they sometimes get it wrong.
I suggest you all contact Apple about the problem via itunes store support here:

USB audio problems with 2013 iMac

I'm having a strange audio problem with USB microphones and headsets. The issue with my Logitech H650e is shown in this screencast I recorded. In the first part of the screencast, I am not speaking into the mic—yet you can see the levels fluctuating as if there is static playing (not in a natural pattern that you'd see when someone is speaking). In the next part of the video I demonstrate that selecting the built-in iMac mic for input, and then re-selecting the Logitech headset temporarily solves the problem. You can see the input start to fluctuate normally as it should when I am speaking. But at 0:31 in the screencast, you can see the input levels freeze and stop registering anything. I continued to speak until the end of the screencast, but no input was detected. For this screencast, I was on a Go To Webinar call, but the problem occurs regardless of whether I'm using Skype, Go To Webinar, GarageBand or any other software.
The problem with my Blue Yeti USB microphone is also different. In that case, the input does not freeze as it does with the Logitech headset. The levels appear as you would expect, and it seems to work. However, the person on the other end can hear static in the background, even though I don't hear it in my own headphones. I learned this because I just tried to do a Skype interview with the Blue Yeti, and the interviewer told me they could hear static. We closed Skype and called each other back twice, but the problem persisted. Then, suspecting the problem was related to what I described above with the Logitech, I unplugged the Yeti and then plugged it into my Macbook Air 2013 (also running Mavericks). Lo and behold the static completely disappeared.
My Griffin iMic and Audio Technica lavalier mic (attached to the iMic) behaves similarly to the Yeti, except in this case I can hear the static when I speak with my monitoring headphones. The input works but I get a lot of cracking and static in the background. This was confirmed by calling the Skype Test Call number and recording a message, which is then played back.
Here are the facts:
All 3 of my USB audio microphones/headsets do not work with my 2013 iMac running Mavericks
All 3 of these microphones/headsets worked fine with my 2008 Mac Pro running Mountain Lion
All 3 of these microphones/headsets work fine with my 2013 Macbook Air running Mavericks
In this other thread, several people are reporting similar issues with the iMac 2013 and Mavericks. At least two people did not have the issue when the iMac 2013 was running Mountain Lion. This of course suggests the issue is the combination of the iMac 2013 and Mavericks.

Audio Problem since upgrading to Mountain Lion

Has anyone encountered audio problems with their iMac? I just upgraded to Mountain Lion on my i7 27" with 16GB of Ram and found that the Audio starts to get distorted and eventually cuts out after about an hour! It starts cutting in and out when I move the mouse and eventually there will be no sound at all!
Sometimes it can take over an hour of steady use, my last time was watching a movie on Netflix. I initially noticed this using a USB DAC Headphone Amp.
I never had any Audio problems before, my machine is over 1 year old.
I enjoy watching movies in iTunes and DVDs, but this is making it difficult! A full restart usually fixes the problem for a time but it will eventually come back
I'm seriously thinking of going back to Lion for the time being and seeing if it is a Hardware problem.

i don't know if mine is the same issue, but i had no sound through any of my applications after upgrading to mountain lion. here is what i had to do to fix it:
-- applications > utilities > audio midi setup > UNmute all options under "built-in output" (they were mysteriously muted)
Also, I noticed that the options for "use this device for sound output" and "play alerts & sound effects through this device" were no longer assigned to my Built-in Output device. They were assigned to some other random sound driver. To fix, i right-clicked on Built-in Output and reassigned those items to my built in speakers. All fixed now!
very weird problem, though.

It's an audio problem, how can i fixed it?

hey, why my imac 10.7.4 suddenly don't give a sound. the volume icon cannot be click, it's an audio problem, how can i fixed it?

this should only happen if you have a digital toslink connected to your audio jack. is there a red light coming out of it?
have you tried restarting the computer?
does your system see your audio device in about this mac more info audio?

Audio problems when exporting

Hi there.
I'm having trouble exporting my video file. The resulting .mp4 has audio that is screeching. See video below, password 'audio55'.
Private Video on Vimeo
The problem arose when I updated from Leopard to Yosemite on my imac. The audio was messed up upon export whether I used CS5 or CC. So I used Time Machine to jump back to a date before I upgraded to Yosemite and now I'm exporting from CS5 again, using OS X 10.6.8 (Leopard) and the same issue still happens, as shown in the video.
I have been using this footage (AVCHD) with the same sequence settings for years. There is one error that pops up before I open the project, that the Scratch disks are write protected or unavailable and that they need to be set to my documents folder, which I 'ok'.
Please help!
Thanks,
David

Hi there
I've seen others report that it's helpful to adjust the audio so that each slide doesn't begin playing audio until .2 or .3 seconds into the slide.
Perhaps try that and see how you fare.
Cheers... Rick

Audio problems and can't open project to another computer.

I'd like some help with moving a project from my G4 powerbook (10.4.3 1Gb RAM) to my G5 iMac (10.4.4 1.5Gb RAM) both with ilfe 06 installed. I copied the project file across and it won't start up on my iMac. The reason I'm trying to move the project over is that the audio quality on the entire (powerbook) project is absolutely u.s. (created on my brand new powerbook with factory settings intact). I have already used iMovie on my iMac with the same camera and it worked just fine and was kinda hoping that 'porting it over might cure the problem, although I'm not at all sure it will. I think the fault is probably embedded in the original. (incidentally, I CAN open the moved project when I connect my powerbook to my iMac)
Audio problem:
I noticed, while importing the clips, that my powerbook started sporadically cutting out the audio (unusual I thought!) but I was under a bit of pressure to complete and thought it was just a temporary glitch.
I'd appreciate some help with that also, if anyone has a suggestion.
Anyway, as I said, the project simply won't open on my iMac (I've checked permissions they seem OK) iMovie starts up when I click the project, but stalls until I click iMovie's icon in the dock, where upon the previous project I worked on loads up fine.
Most frustration overall, I thought if I had 2 machines I would have ultimate flexibility - It's not woking out like that at all.
I'm apprehensive about upgrading my powerbook to 10.4.4 at the moment - frightened I'll loose the whole thing!!
I've used iMovie 2, 3 and 5, never had any issues like this before.
iMac G5 + Powerbook G4 (10.4.3) Mac OS X (10.4.4)

Same here. I don't have a solution, but I understand exactly your problem. This is what I did.
Imported movies into iPhoto from stills camera.
Opened iMovie, new project bla bla, dragged from event library (iphoto videos).
Made/edited movie etc.
All gone well. Exported to iTunes/iDVD etc no problem.
Now, I don't need to keep all the original video clips in iPhoto so can I delete them?
Yeah sure, I'll just drag the iMovie project to my ext HD as per the iMovie help files.(in iMovie)
Opened project that is now on ext HD.
File/Consolidate/Copy clips & Move events.
But.... it doesn't. The 'Copy clips' box even says '2.2gb' which is the right amount for the movie clips. But they never go to the iMovie project file on my ext HD.???

Serious Motion 5 audio problem

I add a clip with clean (waveform examined) audio into Motion 5, process it through "Analyze Motion". On playback, there is an unholy audio blast through the speakers when the playhead passes each of the first two keyframes. If I export the clip, the sound artifacts are quieter but still there. Examining the audio in the output clip, the waveform becomes a solid bar that goes off the top of the scale where the problems are.
That was on my Mac Pro. I replicated the procedure on my iMac with exactly the same results.
Both machines are on separate UPSs on separate electrical circuits and both run OS X 10.6.8.
Mac Pro 6-core 3.33-12Gb, iMac 24" 3.06 Core Duo 8Gb, MacBook Pro 13" 2.7 Core i7 8Gb

The clip is a DV clip of an an egret flying. I had applied Analyze Motion from the Motion Tracker folder and manually entered a number of keyframes. I can't recall what other actions I took, if any, because I was just playing around trying to learn the program. I thought that if I went back to the autosave versions of the motn file, I might be able to figure it out, so I reloaded one and it reproduced the problem as before.
I then moved the motn file from the Autosave folder into a "Motion Problem" folder while assembling all the relevant elements for submission (to?). When I reload this file back into Motion from there, the problem is gone. Nor does it reappear when I put the motn file back into autosave and run it from there.Very bizarre!
I have made a jpeg of a comparison of the audio waveforms of the original clip and the problem output clearly showing the nasty artifacts but don't know where to send it.
Until I reproduced the situation from scratch (short term memory okay) on my iMac, I thought the problem might be related to the random audio popping I'm getting on my Mac Pro. I suppose I had best just keep my speaker volume low and hope that it doesn't happen again.

Lion Optical Audio Problem

It's an outrage truly. Can't believe the hours I've wasted troubleshooting this problem...and it goes back at least 3 upgrades ago that my optical audio started to fail / stop working once sending DTS 5.1 via toslink. Going back to play audio in iTunes, or anywhere, would fail / no audio. Somehow the audio driver would lock and corrupt the system. No amount of audiomidi setup configuration would do a thing. Reboot was the only fix. 120 of them later....I tried a soundblaster x-fi usb bypassing the imac sound completely. The box worked perfectly! Except, for the exact same problem switching between the 2. It became apparent that the os was screwed...absolutely no doubt.
I gave up and was ready to build my own dang system...sell the beautiful but broken imac to someone.
Low-and-behold, I see this small line item in the list of 10.7.1 fixes tonight - mix of rage, insult, disbelief - how on earth did perfectly working audio get broken and downgraded?
How do we learn more about this product we've purchased that is getting broken by someone, no "sorry 'bout that?", or, "by the way, to our loyal customers going through **** trying to fix their broken audio, we know, we're working on it..in the meantime, here's $25 worth of stupid app store junk, including the sickingly popular birds game for free!"
Certainly this is likely answered in the incredibly boring license agreement I never read. "We are not responsible for hours wasted with broken software."
Done.
Frank

Yes, 10.7.1 appears to work (knock on particle board). I am now able to play a video file with DTS audio, the receiver automatically switches to DTS..Then, I can quit Movist, open iTunes and play 2 channel audio..The receiver automatically switches. Before, I would try to play regular audio and no sound. It seems I am able to switch back and forth without corrupting the system for a reboot.
To be even more clear about my experience; Snow Leopard worked fine for this 'normal' functionality of switching audio from 5.1 to 2ch. It was only during a subsequent update of Snow Leopard that audio broke. It is now, nearly weeks after Lion release, that this has been addressed (a second time - the first osx update to attempt to fix optical audio problems did NOT work).
Were you able to get 5.1 before and now cannot? What app are you using? Do you have a 5.1 receiver?

Thanks for the reply. What I mean is in 10.5, leopard, the page set up and print settings would not keep after printing the first file. Like say I'm in Preview with a .jpg open and I set the print setup to 4x6 borderless, which is a setting my wife uses a lot. If I print the file, which isn't a problem, save the settings for both page set up and printing preferences, close the file and open a different one, the preferences reset to whatever the default is.
I've tried going into System Preferences and tooling with the Printer set up there, but there's no setting for 4x6 borderless that I can select for a default, not in 10.5.x at least.
There were numerous threads in the 10.5 Leopard printing forum concerning this and it was an issue I hope is fixed in 10.6.

Outgoing Audio Problems

I have an intell iMac 2.4 GHz, with 4 GB ram. About six months ago I started to have outgoing audio problems. It's an old computer but works pretty well. Well, except for this. It doesn't matter if I use FaceTime, Google Hangout, Skype (video or just audio), the is static and screetchy noises on the receiving end. I can't hear it on my end. There is no problem with incomming audio, either through voice or video chat, or other steaming services. Can anyone help me out. What do you think this is? A simple mic problem?

Had the same problem, no audio on incoming or outgoing calls and only could hear the conversation of the call if I put on speaker. It seemed to start after I did a recent IOS update this past month. I tried restart, reset and restore of my iPhone but nothing changed. It appears not to be a software issue but a hardware problem. I got my phone this past summer so it was still under warranty and got it replaced.

Logic X audio problems (pop, click, stutter)

Has anyone else experienced audio problems in Logic X? This happens with just a single EXS instrument loaded. When I add notes or playback the audio signal clicks. It seems to be a buffer issue but I'm running 128 samples which doesn't seem that aggressive (especially with only a single instrument loaded). Switching to 256 samples seemed to make things better but it still hitches. I'm running on the latest generation macbook air (core i5 1.3ghz haswell, 4gb ddr3 ram, 128gb ssd) which seems like it should be plenty. Logic is 10.0.0.3 and OSX is 10.8.5 and I'm using on-board sound card. I tried on a core 2 duo macbook air with the same software versions and settings and it works flawlessly. Anyone have any ideas?

I had the same problem with my new 27-in. iMac (Late 2013) and so far it seems to have gone away after talking with Apple support today. I was getting clicks and pops about every 10 minutes and I had to either unplug and replug my Apogee Duet 2, or change the buffer size in Logic, which only provided a temporary solution.
Apple support today had me do the following:
#1 Shut down my computer and unplug everything (all USB's, external hard drives etc.)
#2 Unplug the power cord, wait 15 seconds, and plug it back in.
#3 Turn the computer back on, but as soon as you press the power button to turn it on, you have to hold Option+Command+P+R
#4 You will hear the boot-up chime (or whatever) twice, and after the second chime, let go of the keys.
#5 If you get a Mac Utility screen or something other than your normal login, shut down the computer once more and restart.
#6 Login as usual, and the problem should be fixed.
Apparently resetting the "NVRAM or PRAM" is what this does, although I don't know what it means. He also provided me with two articles to use in the case that it happens again, although he said it shouldn't:
Intel-based Macs: Resetting the System Management Controller (SMC)
About NVRAM and PRAM
Hopefully this will help.

Audio problems frustrating newbie!

As a newbie to Apple products I find myself frustrated with audio problems on my new iMac. In the project browser the video is fine, audio in sync, no video hesitation, but when I view the finished product in full screen mode I get audio out of sync, periods of no audio at all and freezing frames. I burned the project onto a dvd and again, although the project is perfect the dvd download is the same as the full screen preview, scenes freeze,and hesitates and there are lengthy periods of no sound. I've rechecked all aspects of voice overs, music etc, nothing seems out of whack and the movie runs perfectly in project mode. Any ideas? I've read on other forums that this is a problem with imovie11. This is not a happy introduction to Apple!

All I can say is this is by no means a bug free product. But the price is right. I've used imovie for a couple of years. When stuff happens, you can definitely post on this site because the help is very good. But at the end of the day, you have to burn cycles, step back and really analyze what the heck happened and could have cause this issue.
Video can be ******* complicated. The more complicated it gets, the more you should bite the bullet and hit the learning curve and get yourself a copy of final cut. It's a steep learning curve, but it's a serious app. I have no idea what's going on with your problem. Hope you solved it..?
Anyhow, good luck.
BTW, Mac's are not perfect, but light years more enjoyable the Winblows and bloated operating systems of that variant. Don't throw it out the window yet.
