Strange Audio Issue

I swear I'm not making this up.
When I listen to a track on my iPhone, (in iPod) using the built in speakers or plug in speakers or even plugged into my car stereo, the audio is fine.
But...
If I plug in headphones, (and yes I've tried 4 different brands, two were brand new) I get a rhythmic 'pop' in the right channel and I lose all midrange sound. Most songs sound like they're muffled and audiobooks either sound like their underwater or high pitched burbling brooks.
I have tried multiple tracks, even ripping songs from CDs at different kps rates.
I've restored and re-booted the iPhone three times and tried 3.1.2 and 3.1.3.
And the worst of it was that it was working fine Wednesday (today is Sun).

as another piece of info...when i have my output set to my Matrox MX02 and listen through the monitor, this issue goes away and all is on. also, when i turn the monitor off completely, so video output is set to none, it is also just fine. now, i never had this issue when i had a firewire set up. worked great on the timeline as i could play the video, see it play in the monitor and use my computer speakers for editing sound.

[solved] Strange Audio Issue

I am experiencing a strange audio issue with my Intel-HDA ICH7:
# lspci -v
00:1b.0 Class 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
Subsystem: Hewlett-Packard Company Unknown device 30a5
Flags: bus master, fast devsel, latency 0, IRQ 22
Memory at d2400000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access>
when I installed Arch linux the first time a mounth ago on this computer, I had a sound problem that was solved in a very strange way.
Everything worked fine until a week or so (I believe from Alsa 1.0.12). Now sometimes sound works and sometimes it doesn't. For example sometime I boot the computer and have no sound, then I reboot it without doing anything, and then sound works.
I have tried messing with the modprobe.conf:
# /etc/modprobe.conf (for v2.6 kernels)
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.11 ---
#alias snd-card-0 snd-hda-intel
#alias sound-slot-0 snd-hda-intel
# --- END: Generated by ALSACONF, do not edit. ---
#options snd-hda-intel model=F1734
options snd-hda-intel model=z71v
options snd-hda-intel position_fix=1
but it was useless. If I put back the modules in rc.conf everything is worse: sound doesn't work at all.
A diff between lsmod in a "working boot" and a "without sound boot" showed that the same modules where in kernel memory.
A diff between dmesg showed this difference:
< hda_intel: azx_get_response timeout, switching to single_cmd mode...
was present in the not working boot. This line is absent in a working boot dmesg.
The only way to make the sound card working everytime is to remove the snd* modules load from the boot sequence and load the modules "by hand" after the login.
Any ideas?
PS : If something is unclear due to my poor English please tell my and I'll try to explain it better.

phrakture wrote:snd-hda-intel is screwed up - on my thinkpad I had to go into the bios and enable the modem for sound to work. Oddly enough, the modem was off by default.
Also, mine has no PCM listed, I need to use "front" as my PCM level... not to mention the UI is way off with 'tpb' (if you have a thinkpad)
Yes it's not an Arch Linux related problem: I had problems with Debian (Etch and Sid based distros like ubuntu) too (but there I had no modprobe issue on the init sequence. Maybe is a problem of shared IRQs, but I have to study the existing documentation as I am a newbie). The difference is that Arch is simple enought for me to try something like modprobing "by hand" in the init sequence. PCM seems to work, however the volume is very low and I have found no way to make the mic work. Under Mepis I was able to make it work only if I plugged it in windows xp and then reboot into Linux. But I can't try it with Arch as I have erased the windows partition...
I will try the new kernel, study the documentation and then report. Hoping this will be usefull to others too.

Strange audio issue when running render queue via script.

The issue I'm having with AE is odd, and I'm hoping someone may be able to shed light on the matter. I have a very simple composition that, when I render out using the GUI, everything works as expected. The video renders fine, the audio renders fine, etc. However, when I invoke a script that runs the .aep file, sets the render queue for the composition in question, and then renders it, only the video comes through, but no audio. There is nothing in my script prior to the setting up of the render queue that alters any audio layers (i.e. no code shutting off audio, etc.) Has anybody ever encountered this? The audio file is a .wav in 44.1KHz, 16bit, stereo, and will try other formats to see if the problem might with the file itself? Although, I don't see how that would be the case if it is rendering just fine via the GUI.
Any help you can offer for troubleshooting would be great! Thanks for your help and time!

Thanks for your suggestion. It wasn't the output module. I created a custom template for it and ensured the audio was checked. It was an odd fix. I deleted the audio layer, then dragged it back to the timline. Then, it worked. Cost me like two hours of work for that, and I should have checked it earlier. But I still don't know why the original wasn't working.

Strange Audio issue on Satellite L650/0FN

I bought a L650/0FN almost twelve months ago and have had trouble with an intermittent audio "buzz" in all audio file types and sources. The problem is now worse in that the "buzz" now appears to blank the screen and freeze the computer with the only way of shutting down being to pull the battery.
I found the following in a forum thread [http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=235672&#235672] and thought it might provide a solution, but when i go to the intel download page the description for this driver is desktop chipsets and I dont find anything on my machine similar to Rapid Storage Technology Drivers so this may be a dead end. This driver seemed to fix a similar problem in the 0ED.
" Re: Satellite L650-10M - Audio/Video Lag
Posted: 06-Mar-2011 10:23 in response to: Bernz117
I investigated a litte bit and maybe you could solve this issue updating the iRST (Intel Rapid Storage Technology Driver) V10.1.0.1008.
But before you would do this, you should backup the data from the HDD.
I searched a little bit and the necessary driver V10.1.0.1008.or higher is available for download directly on the INTEL website under following link: http://downloadmirror.intel.com/19607/a08/iata_cd.exe "
Any thoughts or advice would be much appreciated. Thanks

Thanks As***,
By "Factory settings" do you mean the bios settings that came with the computer? To my knowledge those settings are all the same as when I bought the laptop. I haven't changed anything other than loading a few programs ie Word and Photoshop. (Im not sure how to check the bios settings on this machine (?)).
I Don't think i have experienced the "buzz" with headphones plugged in, but again, this is an intermittent problem.
I rang the toshiba service line but the fellow I spoke to wasn't much help unfortunately.
Sorry if my description wasnt very clear I'll try to expand on the problem:
The problem began with what can best be described as a slight audio delay or glitch, sounding like a loud "buzz" or "Brrrrrrr" that would last only a few seconds and replace the sound content. This would occur intermittently and unpredictably when playing various forms of audio (including movies and windows start up). At first I wasn't to bothered but the duration of the "buzz" has grown and then a few days ago it grew so bad the it seemed to kill the laptop screen, as it went blank and no command keys could stop it and thats when I had to pull the battery .
Im just getting a bit nervous as my warranty expires soon.

New MSI Z97 Gaming 3 - very strange audio issues

(sorry for the long post)
Hi, I recently bought some computer parts from Newegg and built my first gaming pc yesterday, but when everything was finished setting up I noticed a major issue with the audio. Both the headphone jack on the motherboard and the headphone jack from the front panel connector aren't working correctly.
If I plug in my headphones into the motherboard jack, the audio level is REALLY low. Like, even if I turn up the volume to 100% it sounds like it's only at 10%. I looked through the volume settings for the headphones and didn't notice anything wrong. Then I tried updating my drivers with the cd and ran the live update utility, but nothing changed. Also, the audio will sometimes make distorted/static sounds when the music itself is loud, yet I can still barely hear the music.
The front panel jack is even worse! The sound is much more distorted/static-y when I plug in my headphones there.
I know it's not my headphones fault because they work fine on my laptop. Even if I plug in a different pair, I still get the same low volume and static.
I know the front panel issue is not because of the case. If I put the motherboard in an old HP case and plug in my headphones into the front panel on this case, same issue. (I know the old case normally works fine).
I even tried running a linux live usb in case it was something wrong with Windows. It still had the same issues.
My specs:
MSI Z97 Gaming 3 ATX LGA1150
Intel Core i5-4590
MSI GeForce GTX 970
Corsair Vengeance Pro 8GB
WD Blue 1TB
XFX XTR Series 550W
Windows 8.1 Pro
I would really appreciate some help. It seems like I've tried everything.

Hi
What is the BIOS version your board currently has?
Try without graphics card and with single RAM stick.
You could also try out of the case on non conductive surface like wooden table or motherboard box, and see if it works then. Might be something in either cases shortening the board.

My iPhone 5 is suddenly having audio issues through the headphone jack.

So this is a strange situation, and I'll try to explain in depth so that someone might be able to suggest a solution. As reference, I have an iPhone 5 that I purchased in late-February. I've had every other model of iPhone except for the first iPhone, so I am pretty familiar with the device. I used to be on AT&T, and switched to Verizon when I upgraded to the iPhone 5.
Two days ago, I was on a six hour road-trip, and I'd been playing my music like normal through my car's auxillary cable. After stopping for lunch, I went to plug my music again, but once the music started to play, I realized that only the drums were playing at normal levels while the vocals were very, very soft. I switched through a few different songs, and realized that all the songs were being played at different levels; sometimes the backup vocals were normal levels while the instrumentation and lead vocals were quiet, or vice versa. I decided to plug my iPhone in to charge, and when I did this, the audio levels were all normal. However, the iPhone was NOT charging. I removed the charger, and the audio went back to being weak and distorted. I went back and forth at this for a bit, trying to figure out what was going on.
Since then and after some testing, I realize that my iPhone will now only charge anywhere EXCEPT in the car charger (I simply use my USB cable that came with my iPhone and plug it into the power adapter I have in the car). This morning, I tested the audio in my home speaker system, and I had the same audio issues. Only half the song's tracks would be at normal audio levels, while the other half would be at a very quiet, almost nonexistent level. I tried plugging my charger into the phone to see if that'd make a difference, but instead of the audio going back to normal like it does in the car, the music stopped and there was just crackling and very noisy distortion sounds.
I'm super confused and not sure what to do. This has never happened to me with any of my iPhones. I am updating my software right now, and am hoping that that may help somehow. Otherwise, I'm at a loss. Any suggestions as to what I should do would be greatly appreciated!

Video and Audio issue with cam

Lately my webcam video has not been able to be viewed on the software provided, it has just turned up as a green striped screen, the video show up perfectly when i play with windows media player and other video/music players, but the audio get screwed up, it will start out fine for the first two seconds then it will get very deep and distorted. And solutions?

It is not easy to help with this. I mean if you already had contact with service they should be able to test it and repair. I really don't know which kind of advice we can offer here.
Problem is that we don't know if this is hardware related issue or not.
I have NB520 with my own preinstalled Win7 Home premium and everything works perfectly.
Do you use original preinstalled Win7 starter version?
Have you noticed this strange sound issue when you just listen music (online radio) without watching video?

Outgoing call audio issue

I bought an iPhone 4s in India two days back. I am facing a strange problem when I make audio calls. Very often (not all the time) I do not hear any audio after making an outgoing call though the call go thru' and timer starts clicking. When I checked with the people whom I called, they said that they got the call but did not hear anything at their end. The workaround that I figured out is to press SPEAKER button twice (activate and deactivate) when I encouter this problem. It seems to be working as of now. Not sure if this is a hardware problem or a software problem or if I am missing anything with settings. Can someone help me?
Thanks !!!

Hi raj1434,
Thanks for visiting Apple Support Communities.
If you are not hearing callers, or being heard on calls, use these steps to guide your troubleshooting:
iPhone: Microphone issues
http://support.apple.com/kb/ts5183
Make sure nothing is plugged in to the jack connector.
Make sure nothing is blocking any of the microphones (see the pictures below to locate the microphones on your device)
Make sure none of the microphones is obstructed by dirt or debris.
Turn the iPhone off and then on.
Make sure that the latest version of iOS is installed.
iPhone: Receiver and call audio quality issues
http://support.apple.com/kb/ts5196
Increase the volume during the call.
Make sure nothing is blocking the receiver. If you're using a protective case or display film, remove it and try again.
Make sure nothing is plugged into the headphone jack or the dock connector.
Check the receiver opening to see if it is clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush.
Try another location with better signal. If the audio issue happens only when on a call, it could be due to the location.
If the iPhone is paired with a Bluetooth headset or a car kit, try turning off Bluetooth on your device. Learn more about troubleshooting Bluetooth connections.
If none of the steps above correct the behavior, back up your iPhone and restore the iOS software to factory settings:

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
An American profesor in Europe.
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!

SoftPhone over VPN audio issue

Having a "one-way" audio issue when IPC connects over VPN to any Main Office IP Phones (7960). Remote IPC (softphone) shows "0 Received" Packets, but the IP Phone shows them as being sent.
This does NOT happen if IPC contacts another IPC on a PC at Main Site, or any kind of phone at the other branch offices.
Have looked at all of the audio settings on the VPN IPC unit, they are correct.
Any ideas?

Try to sniff the Ethernet traffic during call setup at the CallManager. When Callmanager sends Call Control messages to remote party, it could send wrong IP address or UDP port as an RTP parameters.
Another components could block the traffic are firewalls. How do you have your VPN tunnel built? Do you use Cisco VPN Client? What terminates your VPN traffic at the central location? PIX, VPN3000 or Router? Traffic may go one way without a change, and some protocol FixUp may be triggered for this traffic on the way back. If you have access to firewall logs, check if you have any traffic dropped.
Good luck,
Mike

Logic 9.1.8 & Mainstage 2 - crashing frequently/audio issues

I have just uprgraded to this set up (though using the same sound card as I did on my Mac Book with Logic 8 & Snow Leopard prevously) - in order to avoid overloading which was happening on my previousl set up.. only to find that this new system seems very buggy - crashes frequently on Logic (Sudden Motion Sensor error - have disabled that now) and Main Stage freezes. Then a wierd echoey sound can happen - whereby any audio is echoed back from DAW, in Logic AND Mainstage.
I have down loaded two plug-ins/VST's since starting to use this new set up - an XILS Lab L.E. verision and a Crystal synth. I've downloaded the up to date Duet drivers from Apogee. (I have an Duet 1.5 that I used with my old set).
Have looked at the Console system log to try and understand what might be happening - it is FULL of text on occasions when Logic crashes - I am not tech savvy enough to unpick it though.
If anyone has any suggestions to help I would be grateful, thanks.
I do wonder if it is a Core audio issue though - given the echoiing that seems to occur...

Strange performance issue with 3510/3511 SAM-FS disk cache

Hi there!
I'm running a small SAM-QFS environment and have some strange performance issue on the disk storage part, which somebody here might be able to explain.
Configuration: one 3510, dual controller, RAID-5 9+1, one hot spare and one disk not configured for whatever reason. The R5 logical drive hosts a 150GB LUN for SAM-QFS metadata (mm in SAM-FS speak) and a 1TB LUN for data (mr in SAM-FS speak). Further, there are two small LUNs (2GB, 100GB) for some other purpose. Those two LUNs have nearly no I/O. All disks are SUN146G. Host connection is 2GBit, multipathing enabled and working.
Then the disk cache became too small, and the customer added a 3511 expansion unit with SUN300G disks. One logical drive is a RAID-1, 1+1, used for NetBackup catalog. The other is a RAID-5, 8+1, providing two LUNs: 260GB SAM-FS metadata (mm) and 1.999TB SAM-FS data (mr).
For SAM-FS, the LUNs form two file systems: one "residing" in the 3510, the other "residing" in the 3511 expansion. Cabling is according to the manual and checked several times by several independant people. Operating system is Solaris 10, hardware is a V880.
The problem we observe: SAM-FS I/O on LUNs on disks inside the 3510 is fine. With iostat, I see 100MB/s read and 50MB/s write at the same time. On the SAM-FS file system which is running on the two LUNs in the 3511, the limit seems to be at 40MB/s read/write. Both SAM-FS file systems are configured the same in regards of block size.
In case I have activity on both SAM-FS file systems, I see 100MB/s+ on the LUN running inside the controller shelf and another 40MB/s on the disk runnin in the 3511 expansion chassis. So, the controller is easily capable of handling 150MB/s.
Cache settings in the 3510 controller are default I think (wasn't installed by me), batteries are fine.
Is this 40MB/s we experience a limitation by the expansion shelf? Don't think so. Anybody has any ideas on this? What parameters to check or to change? Any hint appreciated. I can also provide further details if needed. Thank you.
wolfgang

SUN300G disks sound like 300GB FC disks.
Depending on how many files are in the SAMFS file system, sharing the mm and mr devices on the same RAID array can be a pretty horrible idea. In my opinion and experience, it's almost always better to NEVER put more than one LUN on a RAID array. Period. Putting more than one LUN on an array results in IO contention on that array. And large, unnaturally configured (9+1? Why?) RAID arrays will have problems from the start.
What are the block sizes used on the RAID arrays? It wouldn't surprise me to see that the RAID array on the expansion tray has a very large block size. Larger block sizes are, in general, not better. Especially for SAMFS metadata - which IIRC is something like 8k or 16k blocks.
I suspect what is happening is most of the metadata updates are going to the mm device on the new array, contending with the IO operations on the file data.
How much space is left on each mm device? What does "iostat -sndxz 2" show when you're having the IO problems?

My Ipad 2 external speakers does not work and headphones has popping sound. This all occured at the same time as my Iphone and Ipod headphones only played mono (no, the "mono" option is not on). How can there be audio issue for all these devices?

My IPad 2 external speaker does not work and the original headphones have popping sound when used. This all occurred at the same time as my IPhone and IPod headphones only plays mono (and no, the "mono" option is not on) with the original headphones, as well as, other headphones tested. How can there be audio issue for all these devices at the same time?
As you may have noted from the list of Apple devices I own, I believed in the Apple and the products it was producing; but it is hard to believe from my experience and the other voices within the Apple Community that we are all experiencing the same hardware issues. Especially since I recently, I upgraded to an IPhone 4g (no, my faith in IPhone 5 series is very little) and is experiencing the same audio problem as described above. So now, I am off to the Apple store again to be told that it’s a hardware problem on new IPhone. Really? Apple, what happen to the pride in the product you were producing?

Everyone does things a little differently. I love to "jam " along with iTunes ( or old Lp's) . Always have. That's where/how I've learned to play .
I'm sure leonieDF is giving a proper way to jam along on a keyboard with an iTune. He blows my mind all the time with what he knows. Nuff respects to him !
What I do is make a GB project I call "Jam With". I'll make several new tracks that are blank. Just has a few instruments named in the blank tracks. You can change those per song ...
Because I'm not concerned about changing the pitch / key.... of the iTune or the tempo ... I can simply play along with it.
Peace,
P. Dreadie

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!

Strange import issue .. no longer works in 2.6 or Beta 3

Strange import issue.
I use LR-2.6 everyday but have only played around with the LR-3 for a limited amount of time so the other day I decided check it out and tried to import a handful of RAW(canon) files on a SDxc-8g card via a USB card reader. I set it up to copy and convert to DNG, apply a few keywords and Metadata but when I tried it acted like it imported the first image and then froze. Card reader lights stopped blinking and just stayed on, program task bar doesn’t show any progress, not even for the first image. I then went to the folder that I was going to have the images copies to and it contained a file of the first image, but there is no indication that LR-3 even created it and it doesn’t show up in the catalog. When I tried to close out LR-3 is popped up the “in the middle of a task warning” so I just closed the program and tried it a couple more times to no avail.
So I though o well I will just open up LR-2.6 and import them from there, guess what now LR-2.6 does the exact same thing!!
I thought maybe my card reader was a POS but I was able to drag all the files to a new folder on my desktop and import them from there, nope. Tried rebooting a couple times, even opened a new catalog to test with, in both LR-2.6 and LR-3 and neither will work..
I am stumped any ideas?

Thank you for everyone's assistance
I actually figured out what the problem was, like most issues it comes back to operator error, it seem I had inadvertently chose a "rename file on import" template that I had set up to name the files based on a custom fill-in field in the Meta Data, I normally only used that template when I was exporting images that had been completely edited, so being these images were new imports that field was blank, hence it would import the first image and then do to " don't import subjected duplicates" being checked it would just stop the import process.
