Audio drop outs and continuing problems- Apple Support informed again.

Hi All,
Have had various audio problems with iMovie transfer to iDVD 6. iMovie had the problems initially but a weird trick seems to be helping me.
Copy a random new audio track into my film, paste it, then cut it out then empty trash..... all of a sudden my audio is clean again and perfectly in time with the video. I have informed the iMovies people in Ireland and they are at a loss to explain why this is now ok.
BACK to the plot and iDVD 6.
When I try to export this project from iMovie in iDVD 6 it either becomes an audio garbled nightmare or if I try and import into iDVD 6 I get audio that gradually becomes out of sync with the video visual. I know that this project was recorded in 16 bit audio so no joy there.
I've told Apple in Ireland that there are major audio issues with iDVD 6's audio set up + something they were apparently unaware of. I was assured that the tech dept's would investigate and solve. I am really surprised that they hadn't seen this problem in this forum!!
In the meantime any advice is very gratefully received. I'm on an Intel G5 Imac with 1.83ghz 1Gb sdram and 250 GB HD. So Software is currently limited!! I desperately need to get this project to DVD!!!!
Many thanks,
GUY

SAME EXACT THING HERE. This is what I posted in a diff thread:
2013 iMac 1TB Flash Drive
OS 10.8.5
Constant audio drop outs using Apogee Duet. I have to unplug and replug several times to get the system to recognize it. Sometimes when it is connected, Audio Prefs doesn't even recognize it and it shows up as "Unknown". When I click Audio Prefs before I get in, I get the spinning beachball and it takes a while for it to open. I have been in touch with Apogee but to no avail. It seems to work on my 2013 Macbook Pro, but I haven't tested extensively. It seems to get tripped up if I'm working in Ableton and get a Facetime call or if I try to use Youtube / Soundcloud. The system gets noticebly slower. When I switch back to Ableton, Duet is recognized (sometimes not recognized at all) but I cannot play anything inside the project window.
Not sure what to do at this point

  • AE and Computer- Audio dropping out and stuttering issues

    Hi all,
    I recently bought an Airport Express 2 weeks ago. I hooked the unit up in my bedroom via ethernet(roaming) method.  I use Airplay and turn on Computer and Airport Express to play both in my living room and my bedroom at the same time. Problem is I'm noticing my iTunes in my living room exhibits some stuttering during songs or the audio will start to drop out intermittently and sometimes shuts off completely but the Airport Express is still playing in my bedroom without issue. I've tried turing off the wireless but it doesn't do anything. When I turn off AE in Airplay and just play using the Computer it works fine. I'm not sure what can be causing the interference but it seems its between my computer and AE when they are both turned on.  I would appreciate any suggestions forum members have to help me resolve this issue. I have the 2nd generation AE.  Thanks a lot.

    Hi Macthemini,
    Thanks for using the Apple Support Communities. It sounds like you are experiencing issues with AirPlay between iTunes on a Mac mini and your AirPort Express. The following resource outlines troubleshooting issues for AirPlay performance:
    iTunes: Troubleshooting AirPlay and AirPlay Mirroring - Apple Support
    http://support.apple.com/en-us/HT203822
    Troubleshooting performance issues
    Wi-Fi Connection
    If you are experiencing intermittent playback or significant network lag with AirPlay, it could be due to a weak Wi-Fi connection, interference, or the distance between the Wi-Fi router and your AirPlay-enabled device.
    Ensure that other devices aren't trying to stream to the same Apple TV at the same time.
    Ensure that your Wi-Fi router is set up with the recommended settings for the best performance.
    Certain external devices, such as microwave ovens and baby monitors, may interfere with a Wi-Fi network. Try moving or disabling these devices.
    If your wireless and wired networks are the same, try connecting your Apple TV to the router via Ethernet instead of Wi-Fi.
    Use the Wi-Fi network troubleshooting guide to resolve interference and other issues.

  • Audio Drop Out/Popping sound Problem

    Hi,
    For the last few weeks (since i installed snow leopard i think), i have been getting a lot of audio drop outs, where all of a sudden the sound goes dead and i get a popping sound coming from my speakers.
    I am using a pre sonus fire studio project audio interface, with its firmware updated to the latest (the latest update was a beta snow leopard update).
    I am running logic pro 8 with snow leopard 10.6.2.
    I think i have narrowed the problem down to my presonus fire studio because i totally disconnected it and used logics built in audio soundcard and i didn't get any audio drop out at all.
    I was just wondering if anyone had any similar experiences or ideas and suggestions on what is best to do?
    thanks in advance for any help.
    Tom

    It depends, are you running off battery when this happens? If so then morethan likely it is the audio hardware coming back online. In an effort to conserve power, what Mac OS X does is when you are on battery is that it turns off your audio hardware when it has not been used for a certian amount of time. This popping sound is typical of the audio hardware being powered up.

  • Usb audio drop-out and problems on 2010 Mac Mini

    Hello!  I recently purchased an Apogee Symphony USB audio interface for my Mac mini.  I have been trying for over a month to get it fully functional without having any dropouts.  The interface runs fine for about 15-20 minutes before I hear static (using my DAW, using iTunes, streaming movies on Netflix, etc).  Sometimes the DAW (reaper to be specific) can't play back because the computer lost the connection to the USB Audio interface.  I know this because I launch Audio Midi setup and it does not recognize the Apogee Symphony interface.  I restart the interface and it works fine.  There is intermittent loss at times, inconsistent latency, etc.  I have worked with Apogee support and we've tried everything - newest drivers, firmware update, etc.  I used to run Snow Leopard 10.6.8 and had the same issues; I upgraded to 10.7.5 but had major kernel panics due to the display (or something, couldn't quite figure it out) but I reverted to 10.7.4 and everything runs smoothly... except the audio interface.
    This led me to doing some research online and I think the problem is with USB audio dropouts.  I've tried disabling Bluetooth, Airport, not putting my HD to sleep, etc and still has the same issues.  I've tried two different USB ports:  the one closest to the display and the the one next-to-last. 
    My question is:  what causes the USB audio dropouts and is there a fix for it??

    This happened a bunch of times; I only copied the main gist of the error message:

  • Audio drop out and picture wobble during export to tape

    I use a camera to capture footage from DV tapes - it's its only job and is always connected to the Mac.
    But when playing back the footage from the FCP 4.5 timeline to make a back up DV copy of a finished job it all goes awry.
    The audio cuts in and out - from normal audio to silence and back again at no regular intervals but every few seconds.
    The picture wobbles just as though the camera isn't getting enough power (it is connected to the mains)I watch the playback with the camera's flip out screen.
    On the computer it all looks fine. Playing back the DV tape shows me what I saw on the flip out screen - a wobbly picture with intermittent sound.
    The cables are good. The camera works fine in all other respects, the external firewire drives work fine, the computer is good.
    I'm stumped! I can't export to tape any more...
    But exporting the files via compressor to make DVDs is fine - no problems.

    Playing back the DV tape shows me what I saw on the flip out screen - a wobbly picture with intermittent sound.
    The cables are good. The camera works fine in all other respects, the external firewire drives work fine, the computer is good.
    Not quite sure how you reach your conclusion in the second paragraph. If it displays fine on the computer and is TOTAL JUNK after it heads out the firewire cable - I'd start with every piece of equipment that connects to the computer. Time to do A/B testing. find another camera, A-DV converter, firewire cables, even the computer and test each element.
    good luck.

  • Static and audio drops out

    I am not sure if I am in the right Discussion area. If not, please advise where to post. After having work done (new mother board and power supply) on my iMac I heard a static or scratchy noise in the lower right side behind my screen while listening to iTunes the week after I got the machine back. Some songs(with more treble) were worse than others. My parents and I iChat every Sunday. The static now interferes with our iChats and the audio drops out and then will come back. They hear it more on their end than I do on mine. I tried turning the speakers way over to the left and that did help some when listening to iTunes, hulu but, not the iChat problem. My question is - do you suppose it is my speakers rather than another issue such as bandwidth or setting elsewhere? And if I were to buy external speakers would those then just amplify the existing issue? The computer on the other end is an iMac running snow leopard. Could it be that the microphone wasn't put back in correctly during my last repair?

    Hi paperchase
    That kind of sounds like the right internal speaker is bad or loose and the Internal Mic is picking up on the noise from it.
    One thing to try before committing to a 2.0 or 2.1 External Speaker System, is to test the iMac's external output sound with iPod buds or a set of headphones. That at least will give you a better idea if the problem is with the right internal speaker or something worse like the sound card.
    Likewise if the repair work was recent, then perhaps you should contact the service provider and report that it came back with an intermittent or rattling right speaker.

  • Problem : Audio drops out on multicast

    We are using Quicktime to view multicasted feeds. We read in the SDP file, Quicktime goes off, does the connect...all is well..until you try and fast forward to get rid of the latency (customer wants < 100 ms, which Quicktime can do fine). If you get to the end of the buffering, video still works fine, but audio drops out and does not come back. There is also some audio pops while the fastforward occurs. This behaviour is the same on both the standard player and the wrapped version.
    Have not seen anything in COM interface that can let me see how much buffering is left, otherwise I could simple keep poking fastforward until I have minimal buffer left.
    Here is the SDP file we are using
    v=0
    o=- 1 1 IN IP4 127.0.0.1
    s=RTP session

    There are only two possible causes I can think of:
    1. The fiel your'e using out of FCP is bad.
    2. The encode that DVDSP created is bad.
    > After exporting to DVD using compressor, the audio on the DVD completely goes away 49 seconds in.  It's there on the master in FCP, but not on the DVD.  It goes away in simulator too.  <
    How did you export out of FCP? I always use a self-contained movie. If the movie includes the audio, there's a problem in DVDSP.
    If you are exporting to MPEG2 out of FCP, you must figure out a way to check the audio portion of the file.
    If it goes away in Simulator there's an issue happening right at that point. Does it play in the DVDSP timeline? Does it play in the media viewer of DVDSP? Can you open the exported movie in QT Player?
    Is there anything significant about the 49 second location?

  • Audio drop-out in FCPX with 1920x1080 & 2048x1240p @ 24p (codec Apple ProRes 4444 (Linear PCM))24p

    Hi all...
    I'm new to this forum.
    Is there an audio issue (drop-outs) with FCPX (ver 10.1.2) for 1920x1080 24p, 1080p HD & 2048x1240 24p (2k) - note: films in FCPX are in codec Apple ProRes 4444, Linear PCM?
    Very recently I've been working on a show reel and I have imported a file (short film) to snip out a section to add to the show reel. 
    I set the project to the film's settings i.e.. "set based on first video clip"...(1920x1080 24p, 1080p HD).  When I play the film in FCPX the audio "hic-cups"..."dips to silence"..."drops-out" briefly (up to 0.5 secs in duration) and very frequently all the way through (approx 15 mins long film)...note: audio set is at stereo 48kHz. The audio monitors on the right hand side also show the dip taking place (if it's a long enough drop-out).
    I also have a version of the film in 2048x1240 24p at 2k, again Stereo 48kHz...and this does the same audio "drop-out" all the way through.  I'm unsure what other formats will create this problem i.e. higher or lower aspect ratios than those above.
    Is this a software and/or OS issue?  Or a hardware issue?  Or both!?
    About This iMac details:
    iMac 27 inch: OS X ver 10.9.4
    Processor: 3.5 GHz Intel Core i7
    Memory: 32 GB 1600 MHz DDR3
    Graphics: NVIDIA GeForce GTX 780M 4096 MB
    Fusion Drive 3.12 TB
    Final Cut Pro X was bought & installed with this iMac back in Feb 2014
    FCPX version: 10.1.2
    Note also:  I used Compressor (ver 4.1.2) to convert the files (movies) above to Apple ProRes 422 HQ, Linear PCM and the issue disappeared - the audio and visuals played with no problems.  All films play with no issue when opened in QT player.  They are also fine when exporting from FCPX.  The issue only occurs (as far as I can tell) within FCPX when editing or playing the audio there.
    Has anyone encountered this problem?
    Kind Regards,
    Hakan

    Hi Luis,
    Thank you for that.
    Seems like you have a point about the "hardware" issue.  I'm unsure (new to it all) at what data rate my (er...wonderful) fusion drive provides FCPX for smooth playback - or where I can find that info on the iMac.  Playing back movies in the 422 HQ codec seems to have no issues (when I converted the movie from 4444 HQ). 
    But playing the full 4444 HQ, the picture is smooth, but the audio has these drop-outs - even with "best performance" option ticked. Interesting that the audio suffers, not the picture in FCPX - so not sure what's going on there. I also read - perhaps - that to play a smooth ProRes 4444 HQ movie in FCPX the data rate should be min of 500 Mbs (based upon About Apple ProRes) for HD movies and up (i.e. 2k).  ProRes 422 HQ needs a data rate of 220 Mbs - so that is my upper-limit to smooth video&audio playback with the current system I have, I guess.
    Does anyone recommend a fast USB3 or Thunderbolt drive (500Mbs+) where I am able to run 4444HQ movies with no issues to picture or sound (away from the fusion drive)?

  • After recent upgrade to Yosemite on Macbook air bluetooth audio cuts out and associated video stops with audio. Likewise with airplay and Apple TV. I have deleted all my saved wifi connections and restarted numerous times. I do not expect a resolutio

    After recent upgrade to Yosemite on Macbook air bluetooth audio cuts out and associated video stops with audio. Likewise with airplay and Apple TV. I have deleted all my saved wifi connections and restarted numerous times. I do not expect a resolution from the community, but hope to get the attention of Apple engineers. If you are having same problems or have a miracle cure I am all ears.

    May start my own thread, but I'm having similar issues.
    I've been using an old iMac (running 10.7.5) and Apple TV for years with no issues. Last week I bought a new Macbook Pro running Yosemite and have had audio issues multiple times. The weird thing is that sometimes it works flawlessly, other times (like now) I spend half an hour just trying to get a song to play.
    My issues are: When I got to "computers" in Apple TV to stream my music, my music is sometimes chopper or intermittent, and I seen to know when it's going to happen based on the status wheel just before it plays. When I choose a song, the status wheel will spin for an unusually long time, usually an indicator that the audio is either not going to work, or stutter.
    When it does finally pull up a song, the playhead sits at the beginning of the song for a good 3-5 seconds before actually playing. Then, when it starts playing, it's all downhill. It will play a few seconds, drop out, play a few more seconds, drop out, and then ultimately the playhead will keep moving across the song as if it's playing, but there's no audio.
    Again, this is a new phenomenon never experienced by me. I've tried everything I could think of, some of them all at once:
    • restart Apple TV
    • restart Macbook Pro
    • quite iTunes/open
    • turn off Home Sharing on iTunes then reconnect it
    • unplugging and cycling both my modem and router
    None of these have alleviated the problem.
    The odd thing is, like this morning, the audio started up perfectly and never gave me any issues. It wasn't until later in the day that it started. Perhaps after the macbook pro had been put to sleep? Not sure.
    Regardless, this is an annoying trait, one that's new to me and my system (as stated, worked flawlessly until my new purchase), and is 100% limited to either a) the macbook pro b) Yosemite or c) both of them.

  • Help me!:audio keeps dropping out and coming back in while importing clips

    While importing from my camera (brand new Canon Xl-2) to imovie, the audio from the tape keeps dropping out and coming back in for some reason.This happens with all my tapes. I've tried using a head cleaner and that didn't help. I'm using a Maxtor external hard drive to save the project on. The project itself is kind of big (about 80 GB) Can imovie support projects that large? Could this be a problem with my processor?
    I'm just frustrated beyond belief right now. Any help you can give would be greatly appreciated. Thanks!
    these our my specs: Processor: 800 mhz. Memory: 1GB SDRam. The disk space icon at the bottom of imovie says i have 151 GB of disk space left.

    Hi e
    With a slow computer one has to minimize the hassle.
    I would
    - repair permissions
    - cheque that nothing else is taking resourses from the job (energy saver,
    screensaver, File Vault etc.)
    - I would move material to my ext hd so that I got > 80Gb free (for a 80Gb
    project)
    - nothing else connected than my Mac + Camera and import.

  • Audio drop outs on Apple TV

    Recently I have incurred an annoying problem.   Every now and then the audio drops out for a second or two; there is no lag in video.
    My set up:
    iMac conected by ethernet to router (supplied by ISP: PCCW), connected to Apple TV (1st gen).
    Apple TV is connected by HDMI to Panasonic Vierra.
    I stream from iMac to Apple TV.
    The problem is new.  Only change is new router; supplied after upgrade to optical fiber broadband.
    Any ideas?

    I apologize for the audio drop outs. I have sent you a private message to get account information from you so we can reprogram your boxes.

  • ITouch and Pandora app....audio drop outs

    Anybody having audio drop outs when using Pandora? It used to work flawlessly on my home network...nothing changed except maybe the update from Pandora in Aug? Anyway- tried the Pandora app on my Apple network at work...no problem. Is it my home network?...My network is secure...I have a cable modem and Time capsule wireless router. What is REALLY perplexing is that AOL radio app. streams fine to my iTouch.
    Please anybody have a solution or similar problem with a fix for this? This was/is the best app for the iTouch and a speaker dock! So frustrating.
    Tried reinstalling the app.....no luck
    ...all updates are current.
    any thoughts?
    Thanks-
    Steve

    I saw that post...but I'm not sure it applies to my situation. It doesn't seem to be connected to when my screen is locked or not. As I stated, It works without a hitch at my work but at home it has the dropouts. I would normally think...well it HAS to be my connection or speed or traffic at home BUT Pandora used to work flawlessly...it probably started having the drops after the update. Maybe the locked screen bug has something to do with my problem but I'm not sure. Why would it work at my work w/ an apple router and NOT at home with an apple router?...just plain weird...
    I get buffering with LastFM if that is any clue for you? I don't get any buffering with the AOl radio app.
    As a note I get no issues when I listen to my Pandora on my desktop both wirelessly and wired....so it HAS to be an iTouch/Pandora issue. I hope you are right that the update will fix my problem.
    Thanks

  • Eeek! Timeline audio keeps dropping out and I'm on a deadline!

    I'm REALLY hoping someone has experience with this issue. I search the forums, and was unable to find anything quite like what I've got.
    I've got a 25 minute project in a FCP X timeline. For the most part, it's a simple string-out of ProRes 422 video with AAC audio.
    While playing, the audio drops out at random times for random lengths of time (usually around 1 to 8 seconds).  The dropouts do not occur in the same place with any sort of consistency. It happens every few second, and it's making editing impossible.
    FCP X is the only running app, and I've killed all the obvious background processes. Rebooting doesn't help either.  I've watched Apple's activity monitor and seen no spikes in CPU or disk usage during the silences.  Based on other audio issues I've read about, I tried coping all the content into a new timeline. That didn't help.
    I'm running out of ideas, and more importantly, out of time.  Can anyone suggest a fix?
    Thank you in advance!

    Holy crap!  The media is AAC.  How did I miss that?!  I even typed it!!!  I think I must have confused it with AIC (which isn't even an audio codec).  Good lord.
    Ok... I'm recompressing some of the footage right now -- just to make sure that's the culprit, which it likely is. I'll report back shortly.
    Thank you, Tom!
