Audio Stutter in 10.4.7.

After upgrading to 10.4.7 I cannot play audio through my Powermac's line-out.
The sound appears distorted and is interrupted every couple of seconds (sometimes for as long as up to a minute). This happens in any application (iTunes, QuickTime, etc.)
I reinstalled the 10.4.7 Combo Updater but w/o any success. Does anyone else have this problem??

Hi, Joepy.
Are you stating that you've also tried listening through the built-in speaker and that works without stutter, but the stutter occurs with external speakers?
Check Activity Monitor to see if some other process is consuming excessive CPU. See the "Troubleshooting performance problems" section of my "Tuning Mac OS X Performance" FAQ.
Good luck!

Constant Power Transition Causing Audio Stutter in Exports

I've now had this happen with two completely seperate projects today where I preview my edit, everything looks and sounds good, but then when I export there's a clear audio stutter wherever I used a constant power audio tansition. My solution thus far has just been to take out these transitions, but I'm wondering when this will be fixed.
NOTE: I experienced the Constant Power bug that happen last month that sounded like a super loud buzz. This is different.
Is anyone else experienceing this problem?

Slight audio stutter in IDVD 6 when played on TV

I am new to IDVD, but the program seems pretty good. The only issue I am having is slight audio stutter throughout the slideshow on the burned DVD when played on a TV. I tried multiple TVs and they all had the same hiccup occur and at the same spot. The slideshow plays great in IDVD without any hiccups or hesitation. Also, the audio file is being imported from itunes and I have listened to it several times to rule out a bad song file. Any suggestions?
Thanks.

Aparently, I am just going to create my own thread documenting my frustration on this journey
You learn more that way.
According to their documentation, this is actually a DVD player issue and not an encoding issue. Ok??? Then, how come other programs are able to seemlessly play over 99 slides without the hiccup?
Slideshow audio playback drops out after 99 images at http://docs.info.apple.com/article.html?artnum=302962 explains things.
DVD slideshows with more than 99 images are a recent 'hack' created by Apple. Images in such a slideshow are treated as Chapters and DVDs are limited to 99 Chapters per Track. When you use more than 99 images, your DVD player must jump to a new track for the 100th image. Some players can do this with no problem, others have a hiccup in the audio, and still others reset eveything.
The ONLY sure way of creating a slideshow with audio and more than 99 slides is to create one as a movie in iPhoto or iMove.
Sorry, but that's the way things work.

Problem type starts audio stutter with virtual dj 7.4 denon dn hd2500

I am modifying the correct httpd.conf file on the server, it just doesn't seem to work. - If I put the rewrite rules in the <Directory /> the rewrite works but it adds /Library/WebServer/Documents to the URL.
I also tried putting the rewrite rules in <IfModule mod_rewrite.c> but that did not work either.
mod_rewrite is enabled and running on the server.
I will post the rewrite rules again in the code brackets. Sorry for the long post. - If some one can try them out on their Leopard Server to see if they can get them to work, it would be much appreciated. Again, these work on my Leopard Client but I can't get them to work on Server.

Leopard and Audio Stutter Requiring Restart

Ever since installing Leopard, there will be some random event that causes audio to start stuttering and the only way to stop it is to restart the computer. I use Guitar Rig 2 very heavily but it isn't just the tracks with GR2 active that stutter. Once it goes, it's all the way gone and affects all audio. I normally use headphones and can sometimes go two hours before it fails but it doesn't seem to survive more than five or ten minutes when I'm using the monitors hanging from the audio interface. That kind of points to Presonus incompatibility but the best course of action is not at all clear. Any help would be appreciated as a back-out would be next to impossible.

I finally have a chance to get back and check Q&As/Posts. I actually solved my stuttering, indirectly thru another issue. During the 10.4 OS update, my dock (in Leopard screen) dissappeared. In the attempts to recover it, I fell back on my PC way of thinking and decided to re-install the 10.4 update, and wa-lah, the dock was back, and the stutter stopped and has not returned to this day. It appears the updates could have something to do with it, in addition to, things like a cell phone near by, frequency interference from other electronics, etc. However, I still think it's often an update related matter.
Here's a discussion on the issue, and also do a search in support with "Macbook audio stutter" and do the search for the last 90 days. The search will yield some good discussions, even more relevant ones the last 30 days, one person noting stuttering started after their upgrade to 10.5
Hope this helps.

Mouse and Audio stutter/freezes with Intel ICH9R AHCI drivers

edit: Initially (in original post) I suspected the random mouse and audio stutter/freezes were from a driver update. However between a reboot during these updates I had disconnected an eSATA cable from a drive that was not powered. It turns out the ICH9R when running in AHCI or RAID mode with appropriate drivers installed has problems with some HDDs when the drive isn't powered but the SATA data cable is connected. This is quite normal in SATA enclosures which I have plenty.
What makes this more puzzling is that the stutter/freezes are very tiny and hard to notice IF you don't have any PCI cards connected. With a Intel 100 Mbit PCI NIC connected these stutters became real blocking issue that would have prompted me to return this Gigabyte G33 motherboard (Also affects P35) to the shop had I noticed this issue sooner. I'm not yet sure whether this stutter w/ AHCI/RAID issue affects only the Gigabyte boards but what is certain is that it does affect these in quantity based on how there's others reporting the exact same issue if googling around.

This issue has been confirmed not to be limited to just my system.

Same problem here, it's not limited to Vista, also happens on XP/2003 both 32/64 bit. I'm 99% sure it's to do with the Intel AHCI/Matrix storage driver. It'd be interesting to know what your motherboard brand/model is. Mine is Gigabyte DS2R and I've seen reports of this issue on other forums as well. I'm using the integrated Intel graphics and every component is Intel except Audio Realtek and Network Broadcom. The issue goes away by disabling AHCI/RAID but you lose hot-swap of SATA drives and NCQ.
The primary indicator for this issue is that if any of the SATA ports has a drive that is plugged in but not powered up (and not powered down by the AHCI driver programmatically) then you get this global stutter/studder/hickups/choppy. In audio it sounds like tiny repeats. How bad it is seems to depend on what drive brand is plugged in etc so on some combinations it's very tiny and doesn't happen that often, on other drives it's more constant and easy to detect.
I'd suggest you report at:

btw. My AHCI BIOS/OROM version that is shown on boot with AHCI/RAID enabled is iSRC 1.07 08042006, what's yours?

Though most posts in this thread involve laptops and many of them attempt to isolate the problem in wireless network adapters, let me assure you the same problem can show up in a desktop with wired-ethernet-only. (Admittedly, it's a Realtek onboard gigabit LAN, and Realtek has been fingered by a number of you for its drivers, at least its audio drivers.)
On a brand new core2-quad P35 chipset machine with 4GB ddrII, with a completely clean install of Vista 32 business, I have been suffering intermittent global stuttering. It affects not only audio (of any sort, through any player, whether or not dsp-enhanced) but also video (you can see it in screen saver motion, for instance) and even cursor or mouse movement (hit and hold the spacebar in a text editor and watch the stuttering fun begin!). It's intermittent but not random; that is, it can disappear for a while after I apply one of my stab-in-the-dark fixes (read on) but can come back and then generally remains until I re-apply a fix. It's been like this since about day 1. Well, maybe day 2 or 3.
I've seen so many variants of this problem posted in so many forums, with so many theories, that I could spend the next three months doing nothing but troubleshooting it, assuming I had the budget and time to try endless substitute components or re-builds from scratch, but there's no assurance any or all of that would actually fix it. I do have the Intel Storage Matrix AHCI drivers pre-installed, and Intel itself vaguely alludes to possible 'degraded performance in Vista' with regard to those drivers--is this what they're talking about? They don't say. I do have an Nvidia 8800gts, and Nvidia forums are full of complaints about unacceptable issues with their video drivers, but again it's vague, no smoking gun for global stuttering. I have tried THREE different audio configurations--the onboard realtek hi-def; an x-fi elite; and a c-media based Omega Claro card. I have the problem with all of them. Discovering how musical the c-media card is was a happy accidental side effect of this miserable odyssey, but it really just makes it more frustrating, since I now want to listen to music more than ever but can't find a permanent solution to this vexing problem.
One of the weirdest symptoms is that the stuttering can re-appear (if it has been gone for a few days) just by connecting an external SATA drive, even if the drive is not turned on! Equally weird: simply going into the BIOS and just looking, changing nothing, exiting without saving, can cause it to reappear upon re-boot!
And to ice this cake of weirdness, here are some things that can make it go away (sometimes, at least for a while): removing the external SATA drive and rebooting; removing and re-seating the cards on the motherboard; and clearing the BIOS (jumper or pull out the battery) and then re-entering all the same settings as were there already.
The symptoms are driving me nuts, as audio is one of my main uses for a computer, but it's the HUH? quality of these various actions that can seem to make the problem disappear or re-appear that are really threatening my sanity. If anybody can sift a better clue out of these ashes of frustration than I can, I wish you would post it.

PE13 Audio Stutter on Export to AVCHD

PE13 users, I need a bit of advice on troubleshooting an export of some HD video to AVCHD. Coming from PowerDirector 12, I just purchased PE13 and am experimenting with the software. Several video clips shot via Sony camcorder 1920x1080 60i 30 FPS, none more than about 2 minutes each, for a total of about 7 minutes. I've imported these clips into a new PD13 project, added a few transitions, and exported as M2T - H264 1920x1080i 30 (audio setting: Dolby Digital, 192 kbps, 48 kHz, Stereo). Video looks great, however, audio stutters a bit in some places, a lot in others, and plays fine for stretches. It should be noted that I exported even longer video of similar settings via PowerDirector and have not experienced any audio stutter ever.
When I export this same project as MP4 - H264 1920x1080p 30 (audio setting: AAC, 160 kbps, 48 kHz, Stereo) the audio plays flawlessly.
Are there any settings that may eliminate this stuttering when exporting as M2T - H264? It looks like I may be able to reduce the kbps of the M2T file to 160, but would rather not if it wouldn't make any difference anyway. I'll experiment when I get home to see if lowering kbps helps, but in the meantime, any other advice would be much appreciated.
Thank you.

Thanks for bringing your thread to attention.
When hitting the Reply button to reply, I found a post that I started to send you and apparently did not. The content that I found was
I would say go with the AVCHD.mp4
But consider you can take your Timeline to Blu-ray disc format on Blu-ray disc using
Publish+Share

and have a choice of Presets
Presets

H.264 1920 x 1080p NTSC Dolby NEW
The 1080p ones have frame rate of 23.97 progressive frames per second. The 1080i have are either
25 interlaced frames per second or 29.97 interlaced frames per second depending on NTSC or PAL.
If you want to export to file saved to the computer hard drive, a good choice in your case for a later burn to Blu-ray disc format on Blu-ray disc
would be
Publish+Share
Computer
AVCHD
with Presets = MP4 H.264 1920 x 1080p30
You cannot customize the burn to presets. But, you can customize the preset for the export to file saved to the computer hard drive.
But, those settings will be overwritten in the encoding process in the burn to process to give you the format cited above.
Please let us know if that targets your question.

Cannot deselect 'safe mode' in Quicktime, audio stutter + other errors

So everyone's got a problem with itunes 7 in one way or another. Most popular is the error about audio stutter whilst playing back in itunes. For those of you who havent tried deselecting 'safe mode' in Quicktime, do it now, coz it should work.
But it doesn't for me. I deselect, then apply, then run itunes, still getting the stutter. I then check the setting again in quicktime to find that the safe mode option has magically selected itself again. aarrgh!
To add to this i regulalry get the error message; 'an error occured while updating the defualt player for audio file types, you do not have enough access priviledges for this operation.'
i have made sure i am logged in as administrator, i have slected the options under 'set program access and defaults,' i have reinstalled itunes and quicktime several times. I have disabled my firewall and followed just about every piece of advice available on these pages. Does anyone have any fresh ideas?
SORT IT OUT APPLE!!!!

Same here guys:>) The interesting thing is that iTunes 7 works flawlessly in my other machines running Windows 2000 professional and Windows XP professional. The computer I'm having no luck with is a Windows XP Home addition with Service Pack 2. Of course everything worked fine with the previous versions of iTunes. Another difference may be that the computer in question also has a PCI audio card, an RME DIGI96PAD. I have upgraded the driver, upgraded direct X but with no avail. Apple, WHERE ARE YOU? I can't listen to my music! This will reflect on your stock price you know?

S20 Audio Stutter / DPC Latency...can't fix it. Need help!

Hi everyone,
I recently (last week) bought a Lenovo S20 (Xeon W3520 with memory upgrade to 6GB). I mainly
use this workstation as a DAW for audio recording / editing. Instead of the preinstalled Windows XP (32bit)
and the Vista Business that comes with the DAW, I installed Windows 7. Everything went fine,
system is stable, ThinkVantage drivers are up to date. A NVIDIA GeForce 260 is used as graphic card.
But for audio applications my S20 as it is right now, is simply unusable. I get drop outs/stutter even with the on board sound, if I play back a mp3 or wav file. I deactived unnessary devices / background programs, tested it with HT on/off, tested it without Speedstepping and without Turbo Mode. No difference. I get a regular DPC spike every 15 seconds. And the spikes are really high (16ms). No difference if I plug in an EMU 1820 PCI card instead of the on board sound. Disabling the on board LAN didn't make a difference either.
Take a look: DPC Latency Screenshot
Any idea how to solve this?
Best,
dynamitec
Solved!
Go to Solution.

Hi erik,
thanks for your reply!
It's not that only Pro-Audio doesn't work on my machine. If I simply recover the Vista Business DVDs and try to play a Wav-File or Mp3 with Windows MediaPlayer I get dropouts every 15-16s - without anything else installed. Also websites for example hang if this spike occour. In my opinion this is a serious fault in my system (not to mention that I bought the workstation for Pro-Audio usage, which I simply can't do as it is right now).
I first thought that it's maybe related to the hardware I build in (Graphic Card, SoundCard), but since it happens without any graphic card / additional soundcard installed it has to be a problem with the basis configuration.
I'm calling Lenovo support tomorrow. I really need a replacement, since the workstation is outperformed by my old Q6600 system without any problems. And I'm really feeling like I wasted a lot of money for nothing
Best,
Benjamin

Audio Stutter during playback, ONLY in Soundtrack Pro

Just today when I opened an aiff file exported from a Final Cut project, I noticed that playing back this file in Soundtrack produced a stutter for almost every second, like a metronome. Scrubbing the playhead along the audio waveform would give me about a 1/2 second of audio but then go silent until I let go of the mouse button and grabbed the arrow again to scrub.
The more effects I put into the project, the worse the stutter becomes, but still in the same time (like I said before, like a metronome). It just becomes more pronounced. If I export from soundtrack, the audio is fine. Playing the AIFF file before and after in quicktime, the audio sounds fine.
I've since tried different file types, from MOV to MP3 and each file has the same outcome, so it's definitely something wrong with Soundtrack.
I've tried trashing the preferences, but that didn't help either. I've never run into this problem before and couldn't find any related issues in a google search. If anyone has ever experienced this before, please help. I've used this computer for over a year with no problems and it was used for a couple years before I started using it, also with no problems.

Woo Hoo!!!
Thanks, Tim for the post. I have a G5 Quad 2.5 GHz and I got the same STP stuttering when I upgraded to Leopard. Playback was stuttery. If I exported to AIFF, the output file played back smooth, which was fine until I tried to export a non-aiff file. AAC and MP3 files ALL have the same stuttery audio as the STP source - I discovered this yesterday creating my first podcast.
So, now if becomes an issues. Searching for "Stutter" found your post. Reading the kenstone article cleared things up. Since I import audio from MiniDisc via optical, I already had a cable attached to the input. So, I attached the other end to the output and... like magic, perfect playback.
Heavy sigh of relief!!
Thank you immensely!!

Core audio stutter after user migration (with system settings)

my girlfriends mbp recently fried its logicboard. Shes got a new 13" now, but migrated her user to my mbp in the while waiting. She also imported the system settings (machine name was changed) and since then my core audio is messed up. I use a Tascam US-122, Motu 828MK2 and Digi 003 and at the moment only the Motu and built-in audio drivers work normally. The other two stutter. Re-installing drivers for the devices did not help.
Any advice on what to trash or should i try to install 10.6 on top of this again?
This is a 3 month old install and i'm not keen on doing it again.

anybody?

IPhone 6 bluetooth audio stutter/dropout issue

I have a 64GB iPhone 6 (Verizon) and am having an issue where when I stream music/audio through my 2013 Toyota Sequoia's audio system via Bluetooth, the music will have a stutter/dropout of about a 1-2 seconds every 20-40 seconds while the audio continues to play. If I connect the phone directly through the USB port, the audio is fine and there is no stutter/dropout. There are no pairing issues - it pairs to the Toyota Sequoia's Bluetooth system just fine.
I'm a bit suspicious that this may be something to do with the Bluetooth on my iPhone 6 as I also use the Bluetooth function frequently for phone calls and those on the other line have noted that I temporarily cut out from time to time.
Could this be a bad Bluetooth hardware issue with my iPhone 6? I tried Resetting Network Settings and still have the same issue.
I'm thinking of taking my iPhone to an Apple Genius for help but thought I'd check here first. Any thoughts or insight would be greatly appreciated.

Hello gdungy,
Thanks for the question. After reviewing your post, it sounds like there is trouble keeping a steady connection over bluetooth. I would recommend that you try the troubleshooting steps in this article, it may be able to help you isolate or resolve the issue.

Video/audio stutter

Have latest flash player. Experiencing audio/video stutter. Using firefox and it does smae thing on IE. Running windows 7

All issues are seemed to be caused due to over-load on System.
Uninstall, Disable, Exit any un-necessary programs/tools/utilities running in background.
Update drivers if there are any. Check CPU and RAM usage from Gadget/Task manager. If CPU usage is 25%+ then there are many programs running.
While playing HD audio and Video switch to balanced or HP Recommended power plan.
Use VLC Media player, it's best Video and Audio player out there.
Above steps will solve your problem.

Encoding makes audio stutter

I have a .mov movie that I'm trying to convert to .flv and have a reoccuring audio issue. When I play back the converted video the audio stutters and skips in the exact same places. The audio is fine in the .mov. I've tried all kinds of different settings and get the same result. Is there something I may be missing for a setting?
Maybe the encoder doesn't like the Pixies?

New Powerbook Audio Stutter / Looping / Echo problem

I though people would like to hear the problem that some of the 15" and 17" powerbooks have been having.
I tried recording the sound from iTunes using Audio Hijack, but when the weird audio issue happened and I played back the recording, you couldn't hear it in the recording (i.e. it played normally), so it seems to me that it's related to some basic audio issue (because Audio Hijack couldn't hear it when it was recording iTunes) rather than a specific application.
I was able to record the sound using a cable from my powerbook to another computer (which then recorded the line-in using Audio Hijack).
Here's a short quicktime capture of the sound:
http://s89317810.onlinehome.us/AudioStuttering.mov
Has anyone heard anything about a fix? It doesn't seem to be related to Airport use for me since I don't often use Airport at home.

Hey guys (first post
I own the PowerBook G4 high res model and I've noticed this 'echo' effect when listening to my iTunes. I remember creating another account for my sister and from what I've heard so far, her sound did not stutter.
Although unrelated, my system sounds did not work after some time (emptying bin, copy paste sounds etc.) even though in System preferences the option for such sounds was checked.
I've come from the Windows world and with the normallity of formatting that computer, I decided to format my Mac for other reasons aside (with the included discs) and to my suprise the stutter/echoing problem has seemed to dissapear on my primary account. It's been 3 days since the install and I've been listening to garageband files, midi, iTunes, internet streaming, DVD viewing all of which the sound did not stall/loop.
In terms of a corrupted file, it seems plausable that this may be the case.
Cheers
Anthony
