SOLUTION TO CRACKLE AND POPS WITH NFORCE 4 SLI MOTHERBOA

someone else posted the solution in a thread, props to him/her.
i've tried everything.
different drivers.
Every concievable BIOS setting.
i've done it all.
THIS WORKED on my a8n32sli-deluxe motherboard.
i set my HTT to 800 (x4 with a 200 mhz bus)
ALL crackles and pops are gone and my system is just as fast as it was at 000 (or 5x 200 mhz HTT)
the HTT is the hypertransport bus from the cpu to the system, if you dont know what i'm talking about google it.
no bull**bleep**, nothing else worked, this did.
good luck!

<well after searching the net and on different forums like ASUS and Creative and EVGA i went to my fellow gaming clan m8's and i had one post to me a procedure to try out and see if it works. well so far it has and i have the onboard sound enable, and the augy2 zs install heres a pic of what my IRQ look like now<IMG src="http://img.photobucket.com/albums/v482/SCAVENGER/My%20Gaming%20PC/IRQ.jpg">i will post the procedure he had me do follow it step by step but make sure you have dri've cleaner pro install to make this work since it is used in this procedure<
This little app is a life saver with that crash error. It not only cleans specific registry entries per driver type and related files, but also cleans MS Win default drivers in the installation CABs which MS always installs when it doesn't know what to do.
* Download newest Chipset Drivers, but do not install yet * Download and install any BIOS updates * Reboot and enter BIOS * Set what you want, disabling any stuff you never use (whether it be firewire or midi or whatever) * Reboot to Windows * Uninstall all drivers related to sound and video (the bull**bleep** apps that go with it too) * Run Driver Cleaner Pro and multi-select all video and sound remotely related to your hardware (I select everything under manufacturer name) * Reboot TO SAFE MODE (keep pressing F8 during reboot until you get the menu choice) * Run Driver Cleaner Pro and clean the same things you just cleaned in normal mode * Select CAB cleaning and clean all CABs it has an option to clean * Reboot to normal Windows, cancelling out all the search for a driver gumps * Install the newest Chipset Drivers * Reboot, enter and recheck BIOS settings (chipset drivers can sometimes screw with this) * Reboot to Windows * Install latest OnBoard Sound Drivers if seperate from Chipset * Reboot * Set Windows sound applet stuff, test onboard sound. Any pops? Should be fine * Reboot * Install Sound Card DRIVERS (non of that extra crap) * Reboot * Set Windows sound applet stuff, test both sound sources * Reboot * Recheck sound applet settings, reboot again if you need to set stuff again (it can be difficult to get Win to set some of that in stone) * Now you can install your Video Drivers * Reboot and retest everything * Lastly, I would suggest the latest monthly version of DirectX to be installed
This /should/ either give you a clean and working as you want it system, or give you an indication of where the problem lies, depending on where in the process the trouble begins<i will post if it keeps working good or not. i know it tends to mess up a day later then give me all kind of greif.

  • Found a Solution to crackling and popping on XFI Sound ca

    I have tried many solution attempts found on this forum and nothing seemed to work. I have updated all of the drivers. I have reinstalled several times along with reboots and after all this I just decided to try on last thing and here it is and it worked for me.
    Well after testing this I have found that setting the sample format rate and bit depth to be use in shared mode to 24 bit, 96000Hz (Studio Quality) That the crackling and popping has gone away. I have tested this in a game called Jericho that did it all the time and the game runs smooth and the audio is crisp and clear. I also had problem playing any audio and moving the mouse over icons and the sound would have serious crackling. This has also gone away. The sound in general is a lot better then before. It is crisp and clear. I highly suggest that you check the settings. Go to Control Panel then Sound . Right click on speakers and select Properties . Click on Advanced and in the Default Format change this to 24 bit, 96000 Hz (Studio Quality). This should get rid of all of the crackling and popping. This has worked for me. I have hooked up my speakers direct not by fiber optic. I am guessing that if one used fiber optic then you might be able to use 24 bit, 92000 Hz (Studio Quality) . But I would definitely try adjusting the settings here to try and fix the problem. I have gone back and forth on these settings and it is only clear on 24 bit, 96000 Hz (Studio Quality) . Thanks to you all on this forum for you help in this matter I know this is only my third post but I have been reading this forum for solutions for a week now and have found a solution that worked for me that I have not read yet. I hope this helps everyone or at least some. Godspeed.

    Here are more of my findings after some more testing. I know that I have found the XFI card to work on my vista machine at 24 bit 96000 Hz, but here is something that tells me there is definitely something wrong with these new drivers for XFI cards. Today I wanted to try going back to the HD audio card that came with my Asus Crosshair motherboard. It has an HD Supreme FX PCI Express card. I am assuming this is equivalent to the Creative Audigy 2 ZS card that I also have. I would assume that the XFI card is a step above the HD Supreme FX card that comes with the motherboard. So here are my findings. After installing the card and the Vista drivers for the HD Supreme FX card I ran into zero problems. I switched the settings to 24 Bit 92000 Hz, this is the setting I wanted to use for the XFI card and it would crackle and pop. The funny thing is the Audigy 2 ZS card that I have had absolutely no problem in running 24 Bit 92000 Hz in Windows XP. So you can not tell me that the XFI Card is incapable of running 24 Bit 92000 Hz. There is no way that you would downgrade the better card of the two. I also know from other users that the XFI card has no problem running 24 Bit 92000 Hz in Windows XP. This is a Vista issue that is narrowed down to the drivers. Therefore the drivers need to be reprogrammed. How is it that, Asus can have a card designed or design an audio card along with drivers that work flawlessly in Vista and am audio component manufacturer like Creative just can not seem to get it right Any answers Creative I still had problems with the audio in the Game Jericho with the XFI card but no problems occurred with the HD Supreme FX card that came with the Crosshair board. So I know it is not a problem with the game. The problem lies in the drivers with the XFI card. The problem that I was having incase you all are curious is. In the game you get to a point where you are able to switch between characters. The crackle would occur when jumping into the character Delgado. The audio would crackle and pop. So I would jump out and into another character and the sound would still crackle and pop until you took the first step and then it would go away. It did not matter which character you would jump into from Delgado. The only sound issues where with Delgado. I thought it was in the game after I assumed I had found a fix. But I was wrong because I had absolutely no issues on any character or at any point in the game with the Supreme FX card. I only had these issues with the XFI Card. The funny thing is the game recommends the XFI card.

  • IPhone 4 with iOS6 crackling and popping with USB car stereo playback

    I have just recently upgraded the head unit in my car to an Alpine CDE-133BT. Ever since I bought t I've been using the USB (Made for iPhone) slot. For the first month I had no problems at all, perfect quality playback and functioned fine. The other day though, I noticed an intermittent crackling coming through the speakers. It can't be a defective head unit, or the speakers, as it plays CD's/Aux/Radio absolutely fine.
    Anyone else with similar problem?

    I can't help with an answer, but i have noticed the same thing whenever i hook my ipod up to my pioneer 510-ub through the usb...all other mp3s and flashdrives work fine. the pops only occur when the ipod is hooked up.

  • My iPhone 5 crackles and pops loudly during calls (with and without speaker phone.)  I'm experiencing this same same issue on my third iPhone.  Is this a common problem?  Short of getting the phone replaced (yet again!) is there a solution?

    My iPhone 5 frequently crackles and pops loudly during calls (while using speaker phone, as well as not using speaker phone.)  After being inspected by techs at the Genius Bar, my phone has been replaced twice; thus, I am currently on my third iPhone 5.  Incredibly, I am, yet again, experiencing the exact same issue. Short of getting my fourth iPhone, is anyone aware of a solution?

    if it's the exact same issue, either it's a problem with your service or with your software if you're restoring from a backup each time. it's pretty darn near impossible for 3 phones to have the same exact hardware issue, so that's unlikely. is this an at&t iphone? if so, are you continuing to use the same sim card? if so, get a new one and try that out. if that's not the issue, restore the phone as new and make a few phone calls. if the issue's gone away, there's something wrong with your backup

  • PlayStation 3 (ps3) audio crackle and popping bug

    I'm curious if anyone else out there has experienced this problem.
    For a couple years now, I regularly render my projects to mp4 (h.264) files at 1080p for playback on my PS3. In Premiere Pro CS3, I had made a couple customized presets with all the right settings for smooth playback on the ps3, which took quite a bit of research and experimentation to get just right.
    Now in Premiere Pro CS5, the few h.264 default presets I've used work really well out of the box, with one small caveat. On a particular music video I've been working on, the audio has quite a few crackles and popping sounds in it. I've researched the heck out of this, initially thinking it was a problem with my render... deleted my audio peak files over and over, changed projects to 44.1kHz and/or 48kHz, use the original WAV file, etc etc ad nauseum. What was most confusing is that I couldn't hear any of these popping sounds when I played the exact same mp4 on my computer. In fact, it sounded perfect on my computer no matter what I did. In diagnosing the problem, I connected my computer directly to my stereo (bypassing the PS3) and sure enough the audio was perfect... so...
    My thinking now is it's some sort of a bug or perhaps a very nuanced incompatibility betweeen the ps3 and the mp4 file. I've re-rendered the mp4 in countless ways, tweaking nearly every encoding setting possible. So far, I've found two things that work and cause the audio to play without any clicks or pops on the PS (again, they all sound fine on the computer)-
    1. Rerendered at 720p instead of 1080. Audio plays perfectly.
    2. Replaced my video track with a single white color matte, rendered at my original 1080p. Audio plays perfectly.
    Anyway, that's where I'm at. Given it plays so well on my computer, I'm half thinking the PS3 is on it's way out as my HTPC solution.
    Curious if anyone else in the community has experienced anything like this?

    Just some thoughts here. Many users have had issues (some Audio on Export) with Apple's H.264 CODEC (probably the most common one?), and have had much better luck with the H.264 from either Lead, or from MainConcept. Not sure if either have a trial, but might be worth a try.
    Otherwise, I am at a loss to explain why your H.264's are producing bad Audio on the PS3 (have never used one). It is also odd that by dropping the Video resolution down, or replacing it with synthetic Video, would have the affects that you describe - odd indeed, at least to me.
    Good luck,

  • Iphone 4s usb audio crackling and popping

    hi my iphone 4s crackles and pops when listening to music using usb audio playback in my car
    my ipod is fine just the phone that does it
    anyone know of a fix ??

    The system in your car is probably not designed for use with an iPhone. The radios in the iPhone can put out quite a bit of interference. If the system is not designed for it, this can result in very poor audio quality. Try putting the phone in airplane mode and see if the problem persists. If it goes away, then it's a compatibility issue with your head unit.

  • Static, Crackles, and Pop Sounds

    I have a Sound Blaster PCI Express X-Fi Xtreme Audio sound card?(.04.0000 Drivers) and it makes crackles and pop sounds when:
    - I'm watching a video online in fullscreen (for example: Youtube, Gamespot, IGN)
    - When I'm watching any video in fullscreen on Windows Media Player
    - When playing a certain DVD or CD rom (for example, a movie or a music cd) the sound will go all static
    - The sound will also crackle and pop in other programs when a movie or music DVD/CD is in my dri've, but not in use
    - Certain games are unplayable because of all the static sound (for example: Starcraft)
    - When I play?Street Fighter IV and Battlefield Heroes, I don't experience crackling or popping, but rather?poor sound quality (it's like sound coming from very bad?speakers with no bass).
    My specs are:
    Windows XP Professional SP3
    Intel Core i7 @ 2.67Ghz
    3 GB DDR3 Ram
    HIS Radeon HD 4870 52 MB
    Asus P6T Delxue Motherboard
    I have disabled EAX Effects, X-Fi CMSS-3D, and X-Fi Crystalizer in the Creative Console. The sound card is currently in my PCIe x6 slot. I have tried putting it in my PCIe x4 Slot, but I get the same problems. Also, when I plug in my mic, it does not work! Why is that? and how can I get rid of these crackles, pops, and static noises?

    Turns out I'm not very familiar with the Xtreme Audio cards which I'm pretty sure don't have an X-Fi chip, just some X-Fi algorithms in software. I'm not sure how much help I can provide. Have you tried CL Support?
    What are you using for speakers?
    If you get complete static, that could be attempting to send an encoded track like Dolby Digital, DTS, DTS CD Audio, to analog speakers. That would be a matter of making sure the player software settings are correct.

  • Audio Clicks, Crackles and Pops

    I'm new to final cut express (but not to video editing). Everytime I export a project (no matter if it's mpeg, quicktime etc...) the audio has random crackles and pops. It's not in the source footage, and doesn't show up in audio programs. The only thing I find that is consistent is that it happens when using MP3s. Does anyone know how to eliminate this??? The source audio files are clean but upon export a lot of annoying snaps crackle and pops! Thanks for the help.

    FCE is happiest with AIFF audio at either 32kHz or 48kHz, depending on your sequence settings. You'll have the least trouble if you convert audio files before bringing them into your project. Also, you should do an audio mixdown before export: Sequence>Render Only>Mixdown.

  • Snap, Crackle and Pop!

    So I am pretty sure the answer is yes, but I unplugged my Time Capsule today in the hopes of resetting it, and when I went to replug it into the power supply all I heard was a snap, crackle and pop. Then, about 2-5 mins later I smelled burnt rubber...I am guessing this means my Time Capsule is pretty much dead?

    Would wireless transfer of data be slower than a USB connection? and ....I believe that there is a built in router withe Time Capsule?....how would this go down with my present BT router?...BT being my current ISP.
    Not John but can assist.
    Wireless is slower than USB. Are you currently using wireless to connect to the modem/router?
    If you want to use TC you can certainly turn off its router... it is there but optional..
    For iMac though an external drive is nothing bad.. and TM is faster and less issues than remote network drive. Definitely go for drive you plug directly into the iMac. And although USB is much easier to get and more readily available Firewire is the port of choice. You occasional see them for sale as FW is dropping out of popularity.

  • Laptop M500 - ST6422 - Crackling and popping sound. How to resolve it?

    Hello
    I own a toshiba M500 - ST6422 and from the beginning a had sound issues when i listened to music or watched movies.
    I saw that a new bios version (2.50) was released to resolve this issue and I installed it but my problem is still there. I still have crackling and popping sound when i listed to music and watch music. It appears at random. I trie dto catch if the CPU reached 100% but it didn't.
    How can this be resolved?
    I  still have warrancy until december, if i take it to there, can they resolve something?
    What is the problem? Driver/ sound card/ other?
    I really need ansers on how to resolve this issue, untill my warrancy ends.
    Thank you in advance

    so, i went with it at a service who handle toshiba warrancies too. They tested the hardware and said everything is ok, must be a software problem.
    So i did what you asked, installed it out of the box, and it doesn't give me the same bad problems, but they still occure but seldom than before.
    So it must be a software problem indeed, which toshiba didnt resolve with the new bios version 2.50.
    Anyway, the problem is another one. I used to install windows in a custom way on 50 GB so I could use the best of the rest of GB for other partitiions. Now, with out of the box installationg, i cannot shrink too much of C partition (the one with windows), it doesn;t let me , so i am stuck with 119GB on C. Isn't there anything to be able to take like 60GB from C to another partition. I tried to defragment with it was 0 result.
    Thanks
    I am also waititng for other advices to be able to resolve the software problem with audio.

  • Crackling and popping sound when playing music and watching youtube videos

    there is a crackling and popping sound when i watch videos on youtube or play music/videos  using vlc media player  and windows media player. recently it has gotten to a point where it happens when windows is starting up or even when the laptop is required to play a sound for example when i plug in a removeable hardware such as thumbdrives

    Hi @donnabail ,
    Thank you for visiting the HP Support Forums and Welcome. I have read about your HP 2000 Notebook and getting a buzzing or popping sound while playing music and watching Youtube videos. Try performing a hard reset.

  • Crackling and popping after updat

    I have an X-Fi Platinum card and after the newest update i got bad crackling and popping. Now i was told in another thread to install the older ones. So my question to all is what?is the best way to uninstall the new drivers so i can install the old ones ---will an in-place reinstall using old drivers cause any problems? I really dont want to use 3rd party programs like driver cleaner.

    Is is "static" (popping and cracking link an FM/AM radio might due) that your hearing or is the audio garbled?
    have you tried using headphones in the same audio jack to see if you hear the same thing?
    if it's static, than it could be a number of things:
    • has your computer ever over heated since you've installed 10.5?
    • Do you house your computer in an extremely humid room?
    • it could be bad wiring or jack

  • 790i SLI crackling and popping sound issue solv

    No, not by a Creative product but by a competitors PCI?sound card.
    I am no longer experiencing any crackling or popping sound during movie playback and durring games on my eVGA?790i system in SLI mode on Vista Ultimate 64.
    The sound quaility and performance are excellent.
    I will be returning my Fatalty Pro this weekend.
    I strongly suggest you do whatever it takes to fix your sound cards Creative. At least one of your competitors was able to design a very good sound card that has none of the issues that the X-Fi does with the 790i.
    Your continuing to sell a clearly defecti've product has cost you my business, a customer that has been using your sound cards for 0 years.
    Gamers dont want excuses, we want results.
    If you cant provide them, we will buy from a company that can as I have already done.

    so, i went with it at a service who handle toshiba warrancies too. They tested the hardware and said everything is ok, must be a software problem.

  • Crackling and popping audio

    Hi, I have a weird audio issue with Premiere Pro CS4. I create the project and timeline with the settings I need to use:
    AVCHD
    1080i
    30 FPS
    48 kHz Audio
    I import my clips (.m2ts files) with no problem except "The file was busy, and couldn't be updated" in the error panel. When I play the file in either the preview or source monitor, the audio has some weird popping/crackling going on. I have played the video files in other programs other than Premiere and have had no such issue. I've tried exporting the clips using Adobe Media Encoder CS4 as different file types, but the popping is there also. Any ideas?
    Thanks!

    I have found a workaround that is annoying as all-get-out but WORKS to eliminate the clicking and popping.
    The Sony camera comes with software Picture Motion Browser (PMB). Right click on the clip in PMB and choose Convert to MPEG. The .mpg result will NOT feature the clicks and pops in the audio. Open the file in Soundbooth and save the .wav file as a separate file; I actually prefer to convert the 5.1 file to stereo (in SB, "save as" brings up a dialog box in which 5.1 is the default. Change this to stereo and the soundtrack will not likely lose a whole lot (the typical camera uses a built-in pair of microphones - just HOW are you getting effective rear-surround, etc.?) but if placed on the Audio 1 track (which is not possible with the standard .m2ts associated audio file) it will display an optical image of the track and be much more malleable than the original, inscrutable version.
    This conversion also allows me to use Soundbooth to normalize the audio (I do a lot of video of small theater and opera companies). Simply unlink (right click the video/audio combination on the timeline BEFORE doing any editing, choose "unlink" click in white space and then click on and remove the original garbage that masquerades as an audio track, then drop in the new one.)
    I have a very strong sense that Adobe tech support knows full well that there is a problem and stonewalls tremendously when asked for a solution. They would much rather make us jump through repeated hoops (such as ftp-ing huge files and then having the complaint ultimately ignored) than admit that this part of their software is not ready for prime time.
    In general, what happens to audio from AVCHD sources is very unsatisfactory. I have had numerous instances where the software has "given up the ghost" and simply not finished laying down a sound track, leaving the end of the file silent. Again there are workarounds (usually putting the clip into a brand new project works but WHY should we have to do that?)
    I hope the next iteration of PP has a lot of thought put into this problematic but potentially extremely useful format.
    OH...I almost forgot...after you're done, and have spent hours of computer time making the MPG conversion...don't forget to delete the .mpg files. They are useless since you're using the .m2ts video file and you've extracted what you need, i.e. the audio. What a waste of time instead of Adobe just fixing whatever the mismatch (and it's likely a mismatch of something) that causes the crackling. I can't tell you how annoying it is to hear a click in the minute of, say an oboe or violin solo!!!

  • Clicks and popping with recording and USB interface-HELP!!!

    I've submitted this twice, got some responses, but has twice been ignored into oblivion. I apologize for the reposts, but this is VERY IMPORTANT, and I've been struggling with this issue for MONTHS now dealing with countless hours of lost time trying to fix it to no avail.
    I'll try to include as much detail as possible.
    I use:
    MacPro 2 x 2.66 Dual-Core Intel Xeon
    3 GB memory
    Logic Express 8.0.2
    245.13 GB empty space on Hard Drive
    THE PROBLEM:
    When I record, I get computerized clips/pops
    http://www.moogiex.com/clickpop.mp3
    http://www.moogiex.com/morecackling.mp3
    I record via a PreSonus Audiobox USB. This problem did NOT start when I got the AudioBox, but several months after.
    When I simply monitor the sound going through the box, the sound is fine.It's something between the Box, and the computer output. My guess is some incompatibility with Logic Express or Core Audio and the AudioBox.
    It is NOT the microphone or the cable (the pops occur with anything going in, 1/4", XLR, different inputs).
    The clicks START with Logic Express. If there are any recording program open when Logic Express is open, and I record, I get the SAME pops.
    It did this both under 10.5.6, 10.5.7, and now 10.5.8.
    It is NOT clipping.
    When I'm recording with LE:
    —There's 1.27 GB of FREE Memory while I'm recording.
    —Logic Express is only using 6.7% of CPU while recording (of only one of the four processors), and about 90-95% of CPU space is free on all four processors.
    —This happens on ANY audio input, and it doesn't matter how many other tracks, how long it is. I just started a brand new file and it does it.
    —This happens when I use ANY input into my computer, but is STARTED by LE.
    Here are my Logic Preferences
    Core Audio- ENABLED
    System Memory Requirement 66.0 MB
    Device: AudioBox USB
    I/O Buffer Size: 1024
    I/O Safety Buffer- UNchecked
    Recording Delay: 0 samples
    Universal Track Mode- CHECKED
    24 Bit Recording- CHECKED
    Software Monitoring- CHECKED
    Independent Monitoring Level- Checked
    Process Buffer Range: Large
    ReWire Behavior: Live Mode (Higher CPU Load)
    Maximum Scrub Speed: Normal
    Scrub Response: Normal
    There is *no* driver with PreSonus' AudioBox. It is simply "compatible." Here's what System Profiler says:
    AudioBox USB (plugged into my Mac Pro's front bottom port):
    Product ID: 0x0301
    Vendor ID: 0x194f
    Version: 1.08
    Speed: Up to 12 Mb/sec
    Manufacturer: PreSonus Audio
    Location ID: 0x00200000
    Current Available (mA): 500
    Current Required (mA): 500
    Here's what I've tried:
    —Disabling CoreAudio, shutting LE 8 off, restarting LE 8, enabling CoreAudio again. This worked ONCE. It hasn't worked since.
    —Disabling CoreAudio, shutting LE 8 off, SHUTTING DOWN, RESTARTING, opening LE 8, enabling CoreAudio again. This also worked ONCE. It hasn't worked since.
    —"CPU Saving Mode"
    —I/O Buffer to 256, 512, and 1024 (default) (IMPORTANT?—speed of popping actually INCREASES with larger buffer?)
    —I/O Safety Buffer checked and unchecked
    —Changing Recording Delay samples
    —Pretty much fiddling with any of the controls
    —Disabling Airport does nothing (was previously working fine with Airport running)
    —Quit all applications, open up QuickTime (pro) or Audacity, and record something. It records perfectly. I go back to LE and the clicks and pops are gone, but only until I use anything with effects, then the clicks and pops return. This works SOMETIMES.
    —Reset the preferences, and that has worked ONCE, and then the clicks and pops came back (albeit not as prominent, but they were still there).
    —I trashed all files related to Logic and reinstalled. Worked ONCE.
    —Restarting does help, but only temporarily, as soon as any pull is put on Logic, the problems return.
    —Using a different USB port. I thought this was the solution because the problem shortly went away with regular use of Logic, but problem came back.
    —Uninstalling Logic, Reinstalling Logic Express, same deal.
    PLEASE, PLEASE, PLEASE HELP. I have a lot of money sunk into all this equipment that's practically useless with this recording issue.

    Man, I feel for you on this.
    I would love to see what your pops and clicks look like in your waveform. If you can take a snapshot of it and post the pic here that might help the diagnosis.
    Your audio files certainly SOUNDS like you have a clocking problem. It really sounds like your CoreAudio driver/MacPro and your USB interface are not locked up in sync - as in: which is master and which is slave? I know some interfaces include a software control panel that allows you to set the status of the interface clock to slave to the computer or to be the master. It sounds like yours doesn't come with drivers but is there any control panel for this Presonus device?
    Another place to check is in Applications>Utilities>Audio Midi Setup
    On the left under "Properties for <your interface>" what does it say for the clock source?
    Also in this panel, to the right it should have a button for "configure device". What happens when you click it? For example in my case it automatically launches my Apogee Duet Maestro control panel. In your case it might launch something similar, although I think you mention that you never installed anything, which I find strange to begin with - that this thing should just work out of the box with no driver at all.
    I've struggle with w similar problem with my Apogee Duet, although nothing of this magnitude, maybe 4 or 5 clicks per 3 minutes of audio and these turn out to always be sample drops where 5-10 samples in a row are all the same in the waveform, as if my interface and computer stopped talking for a milli second. I did find that if my Apogee Duet was chosen as the default or system output in the Audio Midi Control Panel I mentioned above then the clicking was more frequent, as if choosing the audio interface for any system output caused a conflict with choosing it for Logic. I thought this was strange but you might want to investigate that further too.
    At any rate, it does sound like a digital clock syncing issue to me by the sound of your audio. What effect does changing the sample rate of the recording have on the problem?
    Let me know if any of this leads to anything.
