Audio issues under vista/bootcamp

I just got a 13" macbook aluminum and decided to put vista on it aswell with bootcamp. Any time I have audio playing under vista, I experience stuttering every minute or so. Is there anyway to fix it? or is vista just simply not very good to run on macbook?

I had the same issue (running Vista under Bootcamp), and indeed also turned off the 802.11a as described here --> http://forums.macrumors.com/showthread.php?t=468089 Issue immediately went away (suprisingly, didn't even require a Windows therapeutic reboot).

Help! Can't connect to wifi under Vista (bootcamp)

I have no problems connecting under OS X but not under Vista (bootcamp). I checked all the settings in my Belkin router and can't find anything that would cause this. I even tried turning off the security settings, disabling wep/wpa; and even added the mac addresses to the mac control.
However, I was able to connect to the neighbor's unsecured wifi.
Please help! Thanks

nvm, i found the fix...i searched the forum and found a thread in which the poster suggusted a driver download.
I downloaded this driver and it works perfectly....**** bootcamp!

X-fi under vista perfect n

A year ago there was so much problems with vista and x-fi that I sold mine. Since then I have been running 2 computers with Realtek HD under vista with no problems.
But my wife just got a cheap cambridge amplifter (2x40w) and a pair of speakers for her computer. I thought to myself that now she needs a little bit better soundcard to go with that amplifter. And I went and ordered her a x-fi xtrememusic since they are pretty cheap now.
I dont care about eax, cpu offloading or x-fi crystalizer.
She is just going to use it for stereo output to an external amplifter and sometimes swap to headset with microphone. Gonna be used for music, world of warcraft and linegae.
Hope its working fine now under vista? And audio quality under vista is on par with xp right?

It functions. There are a lot of crackling/popping sound issues under Vista, in particular during high-load stuff like gaming, and after resuming from standby/hiberation. However these are purely Vista-related issues. My computer dual boots with XP and Vista, and none of that happens on XP. It'll eventually be resolved between driver and Vista updates. But other than that, it works well and sounds great.
Don't be too quick to dismiss the crystalizer. If your wife plays MP3s, she's going to love it. I have an X-Fi XtremeGamer Fatalty Pro card, and the crystalizer is great for both music and gaming. It's hard to describe exactly what it does. You have to hear it.Message Edited by karl982 on 02-0-20080:20 AM

Bluetooth problems under Vista on MBP

I'm intermittently having bluetooth issues under Vista in Bootcamp on a new Macbook Pro. I'm using a Kensington bluetooth mouse. Sometimes it won't wake up and I have to disable and re-enable the bluetooth driver in order to get it detect the mouse again.
I've also now experience my second BSOD with the error STOP: 0x0000007E on bthport.sys.
Seems like this migth be a bad Bluetooth driver. Under device manager it's just listed as a "Generic Bluetooth Adapter".
Anyone else experiencing these issues or know of a better driver I could get?
Thanks.

I am having the same issue. Everything worked fine until the last week or so. I recently installed Vista SP1. Are you running Vista with SP1?

Audio issues mountain lion

I've hear of audio issues under 10.8 on iMac's with programs such as WOW, but my problem is with FCP X and .mov files in general. I can Quick Look them (spacebar) and they seem to play smoothly, but under Qucktime, Quicktime Pro and even VLC Player the audio does not play correctly. I have played the same file with each program and it skips, stutters, mutes and fails to play properly in different segments of the movie. Any similar experiences?

I've already tried the Midi Setup app by changing some of the defaults. However, like I've seen in other related posts, changing the bitrate and the type of encoding doesn't help much (but, see later).
I've spended yesterday's evening trying to understand what was happening. The DD receiver works fine, since I have no problem playing DVD media from a XBOX.
The surprise was when I've tried to eliminate the HDMI from the equation. I've disconnected the cable from the TV set controling it from remote screen sharing. It worked! I could play media encoded in DD with VLC and DVD media too with no hassle.
However, as I connected again the HDMI, the sound quality became erratic, and although sound can be heard, and DD passthrough was working, there was some "glitches" in the receiver, like micro-cuts of sound, some of them causing the receiver re-detect the type of coding it was receiving.
All this is very odd, as soon as I can I will try the cable in other receiver to discard it, but I fear it's ML fault combined with my setup... I will investigate if downgrading is an option.

Bootcamp 3.1 and imac windows 7 64bit update not installing. Audio issues!

After many days of work getting the windows 7 working in bootcamp in my imac 27 (still with audio issues) I eagerly awaited the bootcamp update and imac updates.
Neither will install.
Then I find that according to tech support as of now I have to reinstall Windows 7 again for the updates to work!
It took me 5 full 8 hours days to get all my scientific programs installed and working, now I find I can't even simply update the drivers I need. I don't want to reinstall.
My only issues are audio.
Here they are:
1) The headset jack works fine on the Mac side, but in Windows 7, it causes the i7 intel CPU to go crazy. There is no CPU spike on the mac side.
2) The headset jack in the imac is a trrs jack. The same as in the iphone, a tri-band jack that has three bands, two audio out channels and one mic in channel. A trrs headset works fine on the mac side with using the headset mic (as in iphone) rather than the built in mic. (this provides much better quality for sound recording). I don't want to use a usb mike.
In Windows 7 the mic part of the trrs headset does not work.
3) In Windows 7 when going into audio devices recording, no audio mixer shows up, so when I do video or audio screen capture the only way to capture the sound is through the speakers and then back through the imac built in mic, rather than directly through the unit. (terrible sound quality) On the mac side the mixer element works fine.
Now I find from other imac users that even the new updates for the imac on windows 7 don't address and fix the audio issues. I am sure not going to go through 5 more days work only to find the audio issues still don't work.
I need these audio aspects to work properly though!
I have tried to get drivers for the cirrus logic audio card, but guess what there are none available and cirrus logic doesn't even recognize the board or offer drivers.
I have many windows programs I must have for my scientific research!I bought the top of the line Imac with all the bells and whistles because Apple promised that the machine could run Windows 7 in bootcamp natively!
It doesn't. This has been a nightmare of problems.
Is Apple going to step up to the plate and make good on their promises?
Does any one have a fix for any of the audio issues, or know how to install the new drivers without a complete reinstall of Windows?
Installing a few sound drivers and software should not require a complete reinstall. Getting the proper drivers for the headset jack audio in and audio out jack should be the most basic of fixes. Making the audio mixer work should be elementary.
If you are an Apple tech person or an Apple user that can help on these issues, please do!
Thanks, Dr. Duke

PS I will post this under Imac windows 7 updates without a reinstall and under
imac Sound issues.

On another thread a few people have responded saying that their imac has the same situation, the cpu is going crazy and the imac gets hot with headphones or speakers plugged in. But this doesn't happen in the mac side.
If you have an late 2009 imac and don't have these audio issues, let us hear from you. If you don't, lay out the problem here.
Here is my last two cents in to the inquiry.
Not only does the cpu run crazy but the imac 27 gets very, very hot. Since I unplugged the headphones, it runs much, much cooler.
Certainly, some Mac engineers should take care of this problem, it seems it is universal on all the imac 27's and from what I gather, the smaller screened cousins too.
Also, we certainly want a stereo mix option for audio in or out, or what is called "what you hear" or wave out. Imac is supposed to be much geared to multimedia apps.
Finally, the mic jack part of the trrs set up MUST be fixed! A lot of manufacturers are going to headset combo jacks as they call them, mic in and stereo out on the same tribanded plug. But, the old single jack for mic in and single jack for stereo out are two tiny parts of the hardware and super inexpensive for the manufacturer. Why in the **** to go to the "advanced" triplug if the **** thing doesn't work.
Mac has a great reputation. I hope they remedy these problems right away.
Anyone whose imac 27 or 24 whose headset plug is working correctly. Let us know! I don't think anyone's is, but I think that few people understand that their cpu is running so much faster with the plug in, plus few even understand the combo jack and the triband, or trrs audio jack! Out of 4 audio technicians I talked to, not one of them knew what a trrs jack was or that you even have a mic in jack as part of the headset jack!
When I told one senior that it worked on the Mac side, he didn't believe for a while, thought my sound might be recorded from the onboard mic, but I proved it to him by tapping iaudibly on my iphone mic headset and and it showing up in garage band clearly and listening to big difference in audio.
As for a usb audio adapter, I am in a neon light environment and find that those adapters are more sensitive to electrical interference. Besides I want to use the headset jack as it was meant to be used!
Thats it.
Again, if anyone using an imac 27 and windows 7 64 or 32 doesnt have these problems, let us know! We are all anxious for a fix!
Best to all!

STILL have MBP audio issues after Bootcamp 3.1

I have a mid-2009 MBP 13" with Snow Leopard, running 32-bit XP Professional with SP3. I just updated to Bootcamp 3.1 after dealing with low audio, robo-voice from the internal microphone, and spooky red light/trackpad nonsense for months. While 3.1 fixed the red light and the trackpad, my audio issues still remain; I get very poor volume on the Windows side and my voice is still distorted, slow and generally crappy when I use the built-in microphone in the microphone test. The mic doesn't work at all in Steam, which is the whole reason I want it. Was 3.1 supposed to fix these audio issues? It doesn't explicitly say so on the download page, but it seems like it's been quite effective for other people, so if it is supposed to fix the audio I suppose I'm going down to the Apple Store.
If 3.1 wasn't a magic bullet, can anyone suggest a fix? I'm pretty fed up by now with this issue. I tried reinstalling the drivers after extracting them from the BC 2.2 update (found that process on these forums), and it did nothing. The link to the New Jersey school's site (another suggestion from the forums) no longer works for whatever reason.
Thanks!

Use Driver Sweeper and the tips on how to use and troubleshoot
http://www.guru3d.com/category/driversweeper/
You may also want to use Windows Installer Cleanup as I mentioned.
Also CCleaner can help.
MSCONFIG.exe can lead you to the services and startup items being loaded
Programs control panel of course to uninstall the program
Device Manager to rollback; or uninstall and manage device drivers
Apple installs a number of drivers, services, startupitems so you really have to get familiar with the OS and where/how to manage things.
Windows 7 supports RESTORE POINTS. Use 'em! and set one before just in case (any good installer or update should create a new one but good to have your own), and make sure there is 10-30GB of space for restore points.

Vista 64, Latest Driver & X-Fi Elite Pro: Audio issue with Pro Evolution Soccer 2008 (Pes 20

Hi,i have formatted XP S.P.2 and now i'm using Vista Ultimate 64.I have got an X-Fi Elite Pro and i have installed all the applications using the CD-Rom.I updated the driver, Alchemy and Mediasource to the latest version.The system is totally clean and updated (I used Windows Update when i finished to install Vista and nothing was installed). I would like to know why i cannot play Pro Evolution Soccer 2008 like in XP: when i enter in the game i have a noise (looks like the noise of the needle in old gramophones...) and i cannot use the speakers (Creative ProGamer G500).If i turn the volume to 0 i can hear it too... i have to switch off the speakers or exit the game to delete it.Is it another bug I tried to uninstall and doing a new installation of the game but... no way men... Thanks p.s.After year and 4 months (release date of Vista) is it possible to have a decent driver... The Audio Quality in Vista Ultimate 64 bit is lower than in XP and the same wave files have distortion with the low and middle-high volume (60-70).
Problems that i have never had in XP... i cannot reinstall XP another time. I bought Vista in 2006 and i cannot use it till you'll release a good sw.

Audio Issues in Captivate 4 on Vista

Hi,
Just wondering if there is a fix out yet to deal with the audio issues in Captivate 4 - I'm running on regular Vista - editing audio in Soundbooth, importing MP3 files into Captivate - clicks and pops abound. Really frustrating and annoying. Is anyone working on improving this and other Captivate 4 annoyances?
Thanks,
Marianne

Hi Chip
Glad it worked for you.
For what it's worth, you will likely find it has nothing to do with Acrobat. I've seen it happen with RoboHelp and with Captivate and other software. Likely something failed during a recent software install of a different package. Unfortunately the symptom appears with a legitimate and soundly installed package.
Good luck in getting it sorted... Rick

Audio crackle/pop with new MacBook Pro under Vista

I just got a brand new MacBook Pro (multi-touch, Penryn cpu) and have used Boot Camp to install Windows Vista on it. Vista installed fine, and then I used the Restore DVDs that came with my MBP to install the drivers. The Device Manager shows that everything is installed.
All is not well, however. Whenever sound is being output, there are random crackles or pops - sometimes there will only be one every 5 minutes or so, sometimes there are 10 of them right in a row. The only clue I can find is that the Problem Reports And Solutions application in Vista says that there is a "Compatibility issue between Intel 82801GBM (ICH7-M) LPC Interface Controller - 27B9 and Windows Vista." There is no solution offered. I don't know if this problem is directly related to the audio problems, but it seems likely.
Has anyone else encountered this? Any way to fix this and stop the audio crackles?

Well after a week and a half of testing and being unsatisfied with choppy audio on my MBP I believe I may have found the answer. The cause lies in the audio API within Vista; there is a specific service (Multimedia Class Scheduler) that adjusts the priority of multimedia applications according to resources available and one of the factors that affects the prioritization is network usage.
I tried pretty much every Broadcom driver available from HP and Dell to no avail; some reduced the frequency of the pops and crackles but none of them removed it completely.
I believe the solution lies within several registry keys that control the Multimedia Class Scheduler service. Open up regedit and modify the following keys:
HKEYLOCALMACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
Set NetworkThrottlingIndex and SystemResponsiveness to 10 each (decimal)
and
HKEYLOCALMACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Audio
Set SchedulingPriority to High.
After changing these 2 keys I couldn't here any audible stutter regardless of whichever driver I used. I am currently using v1.96 for the Realtek and 4.170.77.3 for the Broadcom.

Please FIX, Apple : Macbook Multi-Touch BSOD and Audio Problem in Vista

Readers: The below message is sent to www.apple.com/feedback and to mac-related sites. If you encounter the same problem as I did, please reply and acknowledge the problems highlighted in this thread.
Dear Apple,
First of all, I would like to compliment you on delivering the excellent new MacBook Aluminum series. As someone converted from the PC camp (no less by your expensive and convincing "PC vs Mac" marketing campaigns) , I was delighted how great life is on the Macbook and Mac OS.
However, life on Vista/XP is another story altogether. While I love to do EVERYTHING on Mac, you have to admit there are a lot of times I have no choice but to do my computing on Windows (eg. gaming and many sites still support only IE). Below are the Vista "show-stoppers" i encountered while using Bootcamp/Vista.
Note, I do understand where Apple's priority is in terms of OS support, but the very fact is that you spent so much money converting PC users to Mac (mainstream advertisement and such) so I think you are obliged to meet the expectations you set. Also, many users like me are paying a premium over similarly-spec Windows notebook. So I think it's only right that as customers, we request that you fix these "show-stoppers" which make Macbook unusable under Vista ( which contradicts your advertisement marketing claims...else sooner or later, someone else will be frustrated enough by the issue to raise a class action lawsuit. Won't be me though cause that's too troublesome but it probably will convince me not to do make my desktop switch to iMac ).
1) Multi-Touch BSOD under Vista
I've consolidated some forum complaints below to illustrate how widespread this problem is. Frequently, the dreaded BSOD pops in out-of-the blue while I am not doing anything particularly complex on Vista. The same message always appear that the problem is caused by "applemtp.sys". This is with latest MTP drivers and even disabling the "Apple Multi-Touchpad Mouse" under Device Drivers. I am at a loss what to do here cause it seems that the only way out is not to use the touchpad in Windows !

http://discussions.apple.com/thread.jspa?messageID=9273598&#9273598
2) Audio Crackling/Disappear
Again, I've consolidated some threads below.
Many users hear cracking noises under Vista, when playing MP3, streaming internet audio and gaming. My experience in gaming is that 80% of the time, the audio will be killed halfway in the game. I've got many titles(WoW, Battlefield 2, Last Remnant, COD 4..etc) so the problem is not confined to one title/publisher. Online research speculation believes that this is DPC-related issues due to Broadcom driver but I think the other part is also due to Keyboard Manager in Bootcamp. Even the audio driver itself may be an issue.

X-fi platinum gives out only static noise under Vista x64

hello. I need some help getting x-fi to work under Vista x64.
the card works great under XP. no problems at all.
under Vista x64 drivers install fine. but the card only outputs very loud static sound. sometimes all the time, sometimes only when I try to play music. when I try to play audio the program usually freezes or acts like it takes much longer to play the sound. for example Vista speaker test shows speaker animation for much longer than normally.
switching to Audio Creation mode usually helps some, but still only static.
switching in Vista Sound->Recording devices causes a lot of static to be generated as soon as I switch to it (and nothing is being played).
sometimes there's no sound at all (programs act normally then).
I've tried all X-Fi drivers I could find (newest and older, including from X-Fi Vista CD) to the same result.
tried 5. speakers and connect to front panel.
tried installing drivers in safe mode. tried clearing old driver after driver un-install to reinstall the driver fresh.
if it wouldn't work under XP I?would have sent it back, bet seeing that it works fine there I can only guess that it has something to do with drivers.
any help would be appreciated. thank you.

if anyone experiences the same issue, reformatting HDD and reinstalling Vista from scratch solved tho problem.
I guess there was some conflict with the previous sound driver.

Late 2008 MacBook Pro unibody - Hard Freezes under Vista 32bit

Hi folks,
I am a relatively new Mac fan (started a few years ago when I purchased a Mac Mini for home because I didn't want to suffer Windows at home as well as at work!)
Anyhoo, late last year I purchased a MacBook Pro Unibody jobbie so that I could have the best of both worlds for my work. I can run Visual Studio under Vista for C++ development under boot-camp and run the Mac and OSX for just about everything else.
However: I have a problem that is testing my patience to brand new levels. In summary:
About once every couple of hours or so (and it's not reliable: could be after 30 seconds, could last several hours) Vista freezes. And I mean freeze: it takes a "hold the power button down" routine to get out of it. This, of course, has made Vista and lots of my work pretty upset. There's nothing quite like writing to a file when this happens for maximum tears. I'm running through tissues like you'd never believe
I have done some research on this over the months and have tried many possible solutions including, but not limited to, ensuring that I'm fully patched up and that there is no suspicious software, updating all the drivers (paying particular attention to NVIDIA's ones - as a DirectX/OpenGL programmer for the past 10 years I'm acutely aware of how touchy they are). None of these have worked.
The closest I've come to something that looks like a solution is this thingie called Riva Tuner; but it does not recognise the April 2009 NVIDIA drivers.
I understand that it could be linked with something NVIDIA's drivers do to speed up/slow down the cards depending on load/heat/whatever.
I'm so far down my tether at this point I really do not know where to turn. I love my MacBook, but I need Bootcamp and Vista to do my job. It was my choice to get a Mac rather than a PC, so I guess it's my own fault. I have seen many other users on the Internet who have the same problem but none of them appears to have a fool-proof resolution to this issue.
Thus, I thought I'd come here, get my best begging trousers on and grovel to Apple and to the learned users here to see if there is something that I can do to get everything working again so that I can continue to bask in the MacBook Pro glory knowing that my Vista installation is reliable.
Grovelling over,
Mr Cuttle.

Do you have anything against running Windows in a VM (virtual machine) under OSX to do your work? On the unibody, this is much more stable than boot camp in my experience.
here are the steps I took
1) install smcfancontrol in OSX
http://www.eidac.de/
2) install virtualbox free virtualization software from Sun Microsystems
http://download.virtualbox.org/virtualbox/2.2.2/VirtualBox-2.2.2-46594-OSX.dmg
3) install Windows using virtualbox like normal; use smcfancontrol to bump fan speeds if it runs hot (normally not needed unless you watch video or game).
4) turn on seamless mode and run your windows apps side by side with OSX apps for free.
if you have issues setting it up, read here:
http://www.virtualbox.org/manual/UserManual.html
this video shows how it works, albeit with a weird Japanese game app instead of Visual C++
http://www.youtube.com/watch?v=Z47MKa9Jdwk

Quicktime 7.2 under Vista x64

I am using iTunes 7.3.1 under Vista x64 Ultimate with no issues. However, Quicktime 7.2 doesn't work very well.
When I open .mp4 vidoes which run fine under Windows Media Player, Quicktime Player seems to stubmle.
I get the following errors:
-The video screen turns green
-Video stutters
-Audio seems to play ok
I am running on an AMD 3800 x2 with nVidia 7900GTO video card (using latest WHQL video drivers from nVidia).
Are there known issues with Quicktime with Vista x64?

I have the same issue with QT running on Vista. The new version of QT that just came only made things worse!!! Now the tv shows I purchased from iTunes shuts iTunes down when I try to view them. At first, I was getting the green screen, video stuttering, etc.
I tried ALL the recommended fixes:
- Changing the settings in QT to take off Direct3D
- changing the settings in QT to "safe mode"
- Updating my Nvidia graphics card driver
- Going into my bios to ensure my hard drive was not using the RAID array
- Uninstalling QT and reinstalling
This is DEFINITELY a QT (Apple) issue. They simply do not support Vista. I have already stopped purchasing video media on iTunes until QT is updated to run smoothly with Vista.
All that to say... you can search discussion boards all you want, but there is no real fix for QT to run smooth video (audio is OK) in Vista.

IMovie audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !

iMovie 11 audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !
I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

I have a fix - or rather, a workaround.
WARNING: It is lengthy, but still far better than starting a new project from scratch.
I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
This will require:
A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too, as they will be extremely helpful later.
4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
6.) Once you are done with this, export your newly pieced together audio track.
7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
YOU'RE FINALLY DONE!!!
I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
DON'T USE IMOVIE EVER AGAIN.
I hope this helped!
