Audio problem: jerky playback (stutter like) but not echo or looping

Hello everyone, this just started happening on my g4 powerbook 15 inch.
The audio, even system sounds, stutter-- more like there are brief pauses in the audio, like it is started and stopped rapidly, thus no audio is lost or overplayed just silences inserted to chop up the audio flow.
I have tried the fixes for the echo problem but no luck.
What I have noticed is audio works through the headphone jack and only the speakers are giving me the odd chopped up audio.
I also noted that when this is happening if I open the system preferences it is freaking out.
What I mean is If SOUND is open and I am looking at the SOUND EFFECTS screen (where system alerts are) I see in the PLAY SOUND EFFECTS THROUGH: button (unclickable) a rapid switching between internal speakers, headphone and speakers (ispk).
If I open the OUTPUT window I see this rapid switching again, it will end on internal speakers and this chunky, jerky sound continues.
So does anybody else have this rapid start stop problem? I haven't had any echo or looping, just this jerky playback.
I didn't look at every single post here so I may have missed something related to this.
Any tips would be great.
Thanks everybody.

I don't know what causing the problem, but if you play the files with VLC you can adjust the audio synchronization in its "Audio" preferences if you check the "Advanced" box at the bottom-left.

Various audio problems with the onboard speakers but not the headphones.

The little volume wheel is connected to a variable resistor, which is soldered to the motherboard via 7 pins. when the wheel loosens up, or the pins loosen up, the onboard speakers get flaky or just don't work. We've been seeing this type of problem for a while now, and just thought that the general public should know. Either replace the motherboard, or the volume controller, or wiggle and jiggle the wheel when it gives problems. good luck all, and i hope this little tid-bit helps out.

Hi,
Try the following.
First, download and reinstall the Chipset driver on the following link.
Chipset Driver - Windows 8
When the reinstallation has completed, restart the notebook.
When windows has reloaded, download the IDT Audio installer on the link below and save it to your Downloads folder.
IDT Audio Installer - Windows 8.
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio through headphones.

Can I strem audio to my airport express? but not only iTunes

Can I stream audio to my airport express? but not only iTunes. where can I suggest to Apple make some about it?

Hello keer. Welcome to the Apple Discussions!
Can I stream audio to my airport express? but not only iTunes.
Yes. To stream audio, other than from an iTunes source, to an AirPort Express Base Station (AX) you will need a third-party product, like Rogue Amoeba's Airfoil.
where can I suggest to Apple make some about it?
You can submit suggestions to Apple at the following link: Apple Product Feedback

I am trying to set up iTunes match on my apple tv, but it just keeps showing that it is loading, it has been running for over an hour, what can be done here, it has gone with no problem on my iPhone, iPad but not the tv

Same here and this is driving me crazy. I can buy, but can't upgrade. Grrr.

MPEG-2 playback audio syncing issue (works in Vista but not in OS X)

My setup:
- Mac Mini CoreDuo 1.83GHz, 1 GB RAM
- Elgato EyeTV 410 DVB-T
- Sony KDL-46W2000 FullHD LCD-TV (1920x1080p)
I have a rather complicated problem with audio-video synchronization at MPEG-2 playback. I've spent a lot of hours on troubleshooting in the last weeks without coming up with a solution.
I've installed Vista using Bootcamp on my Mac Mini, and in Vista everything works fine, so it's definitely a problem in OS X and not a hardware issue.
I have a Mac Mini CoreDuo 1.83GHz 1GB RAM. I have done a reinstall of OS X and updated it in Software Update until Software update says my "computer is up to date". So it's completely fresh without any third party software.
As display I'm using my brand new Sony KDL-46W2000 FullHD LCD-TV connected via a DVI-HDMI cable. I don't have to do any custom settings for this display. OS X outputs 1920x1080 progressive without me having to do any additional settings.
The issue is that when I watch DVDs the picture is delayed on the screen about 200 millisec compared to the audio. This isn't the case on all DVDs, but on several DVDs that I've tested. I don't know the differences between the DVDs. It's the same problem if I use VLC to playback so it's not just Apple DVD Player. And it doesn't matter if I use the S/PDIF output to let my receiver decode the audio or if I use the internal speaker in my Mac Mini.
Now to the most interesting part...
In addition to DVD playback problem, I experience the exact same problem with Elgato's EyeTV. But ONLY when using their deinterlace method "Progressive scan". If I use "Always" or "Motion-adaptive" the audio and video syncs just fine.
If I playback other media-files (in Quicktime or VLC) like mov, H264/x264 or XviD everything works just fine and as expected.
As far as I can see the problem only seems to affect MPEG-2 playback. And judging on the troubleshooting with EyeTV deinterlacing and/or progressive scan seems to be involved in some way.
I also tested EyeTV on a PowerBook G4 connected to my TV, and it shows the exakt same problem.

I don't know what causing the problem, but if you play the files with VLC you can adjust the audio synchronization in its "Audio" preferences if you check the "Advanced" box at the bottom-left.

Logic X audio problems (pop, click, stutter)

Has anyone else experienced audio problems in Logic X? This happens with just a single EXS instrument loaded. When I add notes or playback the audio signal clicks. It seems to be a buffer issue but I'm running 128 samples which doesn't seem that aggressive (especially with only a single instrument loaded). Switching to 256 samples seemed to make things better but it still hitches. I'm running on the latest generation macbook air (core i5 1.3ghz haswell, 4gb ddr3 ram, 128gb ssd) which seems like it should be plenty. Logic is 10.0.0.3 and OSX is 10.8.5 and I'm using on-board sound card. I tried on a core 2 duo macbook air with the same software versions and settings and it works flawlessly. Anyone have any ideas?

I had the same problem with my new 27-in. iMac (Late 2013) and so far it seems to have gone away after talking with Apple support today. I was getting clicks and pops about every 10 minutes and I had to either unplug and replug my Apogee Duet 2, or change the buffer size in Logic, which only provided a temporary solution.
Apple support today had me do the following:
#1 Shut down my computer and unplug everything (all USB's, external hard drives etc.)
#2 Unplug the power cord, wait 15 seconds, and plug it back in.
#3 Turn the computer back on, but as soon as you press the power button to turn it on, you have to hold Option+Command+P+R
#4 You will hear the boot-up chime (or whatever) twice, and after the second chime, let go of the keys.
#5 If you get a Mac Utility screen or something other than your normal login, shut down the computer once more and restart.
#6 Login as usual, and the problem should be fixed.
Apparently resetting the "NVRAM or PRAM" is what this does, although I don't know what it means. He also provided me with two articles to use in the case that it happens again, although he said it shouldn't:

Hopefully this will help.

Audio Problems - One Channel Slow and Sometimes Not At All

Hello,
I'm having a terrible problem, since yesterday - but not in the weeks before. The audio tracks are acting very strange. Sometimes one channel plays normal while the other plays at a reduced speed. Sometimes no audio comes out at all. And when this problem starts happening I continually get the 'Warning - Dropped Frames' box every few seconds.
Strange thing is that last night I was having this problem, and although repairing permissions, and trashing preferences didn't seem to have an effect, after moving all the media to a single location it seemed to be working fine. So, somehow, everything was working great last night when I finished working.
I come in this morning, open the same project that was fine upon closing down last night, hit play and one channel's slow, then it doesn't sound at all, then I don't even get sound in the viewer when I open clips there. And now it's constantly stopping with a 'Warning - Dropped Frames' box.
The system is new as of a month ago, everything was working fine on the first project I did.
The Sequence settings and media settings are all correct - that doesn't seem to be the problem. And There was no problem working on the last project with all the media coming off the 500GB internal hard drive, so I can't imagine I'd need to get an external just for it to work.
My intuition thinks it may have something to do with some of the video clips using time remapping, but the main audio that's causing the problem is a music track, not associated with any of the video (so it shouldn't be linked in any way).
I'm using Final Cut Studio 2, with full updates, etc. on a 24" iMac 2.4GHz Intel Core 2 Duo, with 4GB RAM, 500 GB internal hard drive (100GB still available), running OS X 10.4.10.
Please help,
the system is basically useless until this is fixed,
Thanks,

Matt,
I just read your post... I am having the same issue. You have explained the issue better than I did in my post. You can read my comments under the subject Final Cut Pro 6 Drop Frame Issue... As you will read, my issue started last weekend when I upgraded to Leopard. Yesterday, I spoke with Apple Tech (Final Cut Pro Support)... They had me do a clean install of Leopard and re-install final cut studio. Once that was complete, do the software upate. Problem still existed. I then called them back and they had me do a clean install of the origianal OS software from the disk that came with my Mac Pro. I than re-installed Final Cut Studio and did the software updates... I still have the same issue.. And like your post stated, I can be in a project and the sound is perfect and then hit the play bar again and the sound is either distorted or it is like an echo where the track is playing and sounds like a second track is right behind it. (Almost like listening to a radio talk show and the person has the radio on and you can hear the time delay of their conversation.
The Apple support team told me to go into the user preference inside final cut and uncheck the following boxes...
Report dropped frames during palayback
abort ett/ptv on dropped frames
abort capture on dropped frames
They said by removing the checks on the three items above, I would stop receiving the Dropped Frame Error Message (until i unchecked the boxes), I would get the error message every 29 frames when trying to play the clip in the timeline. However, by remiving the checks, I still have the issue with the audio...
Question, Have you updated your software, and if so is that when the problems started occurring?
I agree with your comment "the system is basically useless until this is fixed", Please keep me posted,
Thanks

Problem with .sitx files (Safari but not Firefox???)

Hi All,
I have a website online (with help from iWeb and BBEdit) but am having a problem I cant figure out (this IS my first website!)
I am hoping that someone much more knowledgeable than me can help me with it.
I basically have a download section. Icons and desktops.
Now, when I (or anyone else) tries to download- everything seems to be fine in FireFox (even IE!) but not in Safari.
My desktops are compressed as .zip files. No problems there, everyone can download and open (including Safari users!)
My icons are compressed as .sitx files. This is where the problems come in. Firefox and IE download them no problem ('save to disk?' etc) However when one attempts to download the icons (.sitx files) with Safari it simply displays pages of gibberish (starting with the word 'Stuffit') which I am presuming is Safari trying to 'display' the contents of the actual stuffit file.
Why is this? Why wont safari simply download the .sitx files as it does .zip files?
Does Safari have some sort of inherent problem with .sitx files? Is it some sort of configuration within Safari preferences? or (and probably most likely!) is it something I have done wrong?
Oh, my website (page in question!) can be found here:

Thanks in advance for all your valuable help
Kind regards

Hi,
It sounds like the server the website/file is hosted on is not identifying the type correctly. As you've seen, different browsers will handle this situation differently.

How to get audio clips to play at site but not actually download?

Would like person to be able to listen only to audio clips but not to be able to download clip to add to their iTunes library. In other words, am selling an audio product, and while I'd like people to be able to hear samples at my site (built with iweb), I don't want them to retain clip. Any suggestions on how to accomplish this would be much appreciated!

Stopping people from downloading anything that's published to the internet is virtually impossible.
I would recommend that you first edit your files so that you only have about a one minute clip online....
http://www.iwebformusicians.com/AudioFiles/Import.html
Dragging you files onto the iWeb page is not the best way to present them as a large percentage of PC users won't be able to play them. The Wordpress standalone flash player is still about the best way to play audio and you have to know how to get into the source code to be able to download the files....
http://www.iwebformusicians.com/MusicPlayers/FlashPlayers.html
Or use a flash jukebox....
http://www.iwebformusicians.com/Website-Music-Movies/Flash-Audio-Jukebox.html
For the increasing number of people using iPhone/iPad you can use this dual player....
http://www.iwebformusicians.com/Website-Music-Movies/Wordpress-Flash-HTML5-Audio .html
or have an alternative page using HTML5 players.....

Audio input volume in System Preferences, but not Mainstage

Hi,
I am trying to get Mainstage 2 to work with an audio interface (TASCAM US-122 MKII). I've installed the drivers for the interface, and it shows up on my system both in System Preferences under Audio and in Mainstage. When I go to system preferences -> Audio and play an instrument through the interface, volume registers on the level meter. But if I go to Mainstage and select this interface as my input, I get no volume levels registering at the input.
I've been trying to get this to work for going on six hours now, googling and installing and restarting to no avail. I have the same problem with Garageband too. Has anyone had this happen to them, that an audio interface seems to be recognized by the operating system but not by Mainstage/Garageband?
Thanks,
- Nick

I can't help, other than to say this happened to me today with the same hardware, only with GarageBand.
I recorded bass tracks this morning -- no problem. This afternoon, though, every time I plugged in the Tascam GarageBand went silent, even though the system input shows sound coming in.

IPhone 3Gs audio drift in Final cut Pro (but not qt player or imovie)

Is anyone else having audio drift issues with video from the 3gs when imported into FCP? We find that a 30 minute clip plays just fine in Quicktime player with perfectly synced audio, but when brought into final cut pro the clip has several seconds of drift over thirty minutes. This is before it's ever placed into a timeline, and the issue persists even if we transcode to prores 4:4:4 or any other codec. Issue duplicated in FCP 6 and 7.
Also, the movies are often brought in upside-down, even though they are displayed perfectly by quicktime player.
If, however, I bring the same clip into imovie and export it, the resulting clip has perfectly synced audio which works fine in FCP.
Essentially, apple's free tools seem to have no problem with iphone-captured video, but Final Cut, which is the pro tool, seems to have issues. Unless I'm missing some obvious (or abstruse) configuration step which is causing the problem.
Any insight greatly appreciated; everyone in our shop is stumped.

Shane,
Thanks for your response, though I don't really see the need for the condescending tone while offering no useful information. I'm aware that H.264 is not an editing format -- If you had taken the time to read my post more carefully, you would note that I have already transcoded the footage ("and the issue persists even if we transcode to prores 4:4:4 or any other codec. Issue duplicated in FCP 6 and 7"), so your suggestion "Use Compressor to convert it to DV." really doesn't help much. We've done so and the problem persists. Hence the post.
Incidentally, I have transcoded with quicktime player, compressor, and FCP. All preserve the audio drift. Interestingly, Imovie deals with it well, kicking out a file with perfect sync. My instinct is that it's a metadata issue (i.e. FCP is misinterpreting the actual framerate of the video) but I'm looking for any similar experiences out there.
As for "professional" vs. non pro hardware and software, I certainly don't expect the iphone to shoot footage or offer features that are comparable to those of a pro camera. I do expect it to properly encode quicktime files for use with any bug-free quicktime-based tool, of which FCP is the flagship example. Should aperture not be required to handle photos from point and click digitals because they are not "professional?"
It's a somewhat ridiculous position to take that Apple's video tool would not support their only video-capable device. There are many consumer devices supported by FCP (you've heard of DV, yes?) and the 3Gs (and, I would assume, the coming video-capable ipod touch) are no exception.
In short, this is clearly a bug, and I'm trying to run it to the ground in order to use the 3Gs within a production environment for a project requiring many mobile devices uploading video from wifi connections around the world. If you have any useful information to offer, I'm all ears.

Audio ok when playing on computer, but not there when playing on DVD player

I've made two DVDs on my MacBook: one where I dragged a variety of short films into iDVD (imported via iMovie but NOT edited on iMovie!) and burned it - this one plays fine on everyone's computers and DVD players. The second DVD I created with material edited in iMovie and then burned via Share -> iDVD and while that plays fine on my computer, the audio is "missing" when I play it on a regular DVD player.
I burned the DVDs the exact same way, used the exact same DVD stock, and played on the exact same DVD player, so what's going on? I don't think it's an iDVD problem, I think there's something (not) happening in iMovie...

Audio audible in one Encore timline, but not the other?

Hello,
I'm trying to troubleshoot an issue in an Encore timeline for Blu-ray with an MPEG-2 and AC3 file. It's odd because with the exact same file specs for both video and audio, I'm able to hear the audio from test project timeline (shorter in duration), but not the full length project timeline (roughly an hour and half in duration).
I'm in the process of burning a disk to verfiy that the audio is simply not there, rather than a playback issue with the longer project, but can anyone suggest what might be failing here? Again, the two projects appear to be identical in settings and file specs for video and audio, only the duration of one (working) is shorter than the other (not working).
The audio file has been validated outside of Encore as playing back audio.
Thanks for anything thoughts anyone might have here. Btw, the project has no menu screens. It is for a "play only" Blu-ray disk.
Mtbakerstu

Stan, thanks for the questions / feedback.
As it turns out the file specs were not identical ! No fault of Adobe- an ingest / encode application from another company mysteriously swapped out channels 1/2 of audio to 5/6, and were not readable in Encore. This information was not readiliy accessible within Encore, but was discovered in bringing the audio into Final Cut Pro (where it could be heard).
Thanks again for your thoughts, as always.

Start Up disk problem following kernel panic-mounts but not as a boot drive

I have a problem that I can't solve.
Dual processor G4 with 3 hard drive, all of which are bootable drives with 10.4.7 installed:
A- my primary boot drive - internal SCSI drive (Adaptec PowerDomain 2930U PCI card);
B - internal hard drive that came with the G4; and
C - external Firewire hard drive
Recently, I booted into my B drive and it locked up after it went into sleep mode. On reboot, I experienced a number of kernel panic messages, prompting me to restart my computer.
PROBLEM: Since that time, I have not been able to get my A drive to once again be the Startup Disk.
Diagnostic steps that I have performed:
i. I have run and re-run Disk Warrior from a bootable CD and the A drive as well as the other 2 hard drives mount and are "repaired" by DiskWarrior.
ii. TechTools Pro shows no hardware problems and whatever glitches it has found were repaired.
iii. Disk Utilities consistently returns "Volume passed verification."
iv. Zapped the PRAM
The A drive does mount and is accessible whenever either the B drive or the C drive is the bootable drive.
System Preferences/Startup Disk lists the A drive as a candidate whenever either the B drive or the C drive is the bootable drive. However, when the A drive is selected in System Preferences, on reboot, it doesn't become the boot drive.
I have tried to restart and hold the "C" key down so that I might possibly be able to select the boot drive from A, B or C. But the C key method doesn't produce the intended result, only reverting back to the boot drive in power prior to the reboot. That occurs whether the boot drive is B or C.
At that stage, rightfully or wrongfully, since the problem persisted whether the B or C drives were the startup disk I concluded that the problem could be hardware related and not software related.
On one of the reboots following the kernel panics, a Crash Report was produced - the verbiage
which is code related and so far above my knowledge and experience that it is incomprehensible to me. I can post it separately if helpful but it won't fit in this email message due to restrictions on length of messages.
I haven't had a kernel panic following any of the last 50+ restarts that have accompanied my attempted diagnostics.
Finally, I ran the Apple Hardware Test, version 1.2.6, that came with my G4. First, I removed all peripherals except the monitor, keyboard and mouse (plugged into the keyboard), the Adaptec SCSI card, and a 3rd party FW/USB2 PCI card (OrangeLink+). I ran the Extended Test and an error code was generated during the logic board test: Error Code fire/5/2
That gave me some hope. I next removed the 3rd party FW/USB2 PCI card (OrangeLink+) and re-ran the Apple Hardware Test and no error were reported. Both the logic board and memory passed. I ran the extended test twice, each time no error.
Ah, did that solve my problem? I rebooted and I still cannot get my A drive to be the Startup Disk.
Next, I ran the Rember software (a GUI app for Memtest) and the RAM checked out as fine.
At this stage I don't have a clue. The white towel is about to be waved.
If the problem is the Adaptec SCSI card, I don't know how to test it since it obviously has to be installed to enable drive A to mount.
Does anyone have any suggestions?

I am the original poster on this thread.
Turns out that the culprit behind all my boot problems was the battery on my 5 year old Quicksilver G4. Replaced the battery and all is back to normal.
FWIW, for any Quicksilver owners with SCSI cards, be aware that you can create boot problems for your SCSI drive by zapping your PRAM. As part of my diagnostics I did zap the PRAM but that turned out not to be a problem.
Adaptec's site does include a workaround should you have problems after zapping the PRAM. This specifically covers the PowerDomain 29160 SCSI card/2930U card, which I have.

All you can do is hide them. On the Not On This iPhone page, swipe from left to right on the offensive App and Hide will appear - tap it.
