Airplay audio dropouts, stuttering with Mavericks

I have intermittent audio dropouts with Airplay to an Airport Express and/or a Pioneer speaker with Mavericks. Sometimes these are brief, sometimes the music quits for seconds, sometimes it just sounds like crap. And sometimes it works perfectly. Apple closed a bug report I submitted on this, claiming it was my network. I don't buy that, since my wifi network always tests at above 20 mbps upload, and Airplay only needs 1 mbps for one device, 2 mbps for two.
Are others experiencing these sorts of problems?
Note that this is **not** Airplay video streaming, just audio. And I'm not using Mountain Lion like my profile says LOL.

Use Apple's Wireless Diagnostics as a tool to examine your wireless environment.
You can determine for yourself whether wireless interference is likely to be a causal factor preventing reliable music streaming. To do that, hold an option key while you click your Mac's Wi-Fi icon, and choose Open Wireless Diagnostics...
The following authentication dialog will appear:
Authenticate with your Admin password, then click the Continue button in the following:
The network analysis and diagnostic tests will take several minutes to complete:

Audio interface issues with Maverick

I just got a new IMac and have found that four different audio interfaces won't work with it. Most of these work with my old IMac. I've tried the Apoge Duet, Saffire Pro 24, Presonus Audiobox USB and a new Mackie mixer with USB output. The two of these that have software had lots of crashing issues. Garage band and Itunes are crashing. All of them work intermittently, but then fail with digital distortion or even Mac bluescreen (the little spinning rainbow thing).
I imagine this means I just need to return the computer, but wondered if maybe I just picked four audio interfaces that all just happen not to work with the new IMac and new OS 10.9.1

Scott, I have a 2009 Macpro runing cubase 5.0 with a Mackie Onyx firewire audio interface that has run without major flaw for almost 5 years. I upgraded to Cubase 7.5 which required that I upgrade my OS, so I upgraded to Mavericks. I am now experiencing an unlimited number of dropouts, studders, clicks, and pops That make my$25,000+ studio virtually useless. I called Mackie, because my version does not have a driver as it is the older (non 1640i) version. They said that this version runs through Apple's core audio driver and there was really nothing they could do to resolve the issue (probably why the new 1640i has its own independant drivers). While with troubleshooting, the problem could still be a Cubase based problem, the forums I have read have shown problems like this occouring across a wide swath of different DAWS and audio interfaces. I believe the problem to be on apple's end, and specifically in some failure in Mavericks itself. I tried to call Apple about this problem, but apparently because my macpro is out of warranty they wanted to charge me $20 for my phone call (my Mackie is older than my studio computer, and though they couldn't solver my problem, they took the time to field my call free of charge). I believe what is going on is that they are using the free version of Mavericks to BETA test their OS, and will correct the issues as the complaints roll out. I am going to try and Install Mountain Lion on my computer and see if that solves the problem. It's only $20, and that is the cost of the support phonecall anyways. I'll tell you how it works out.
To the moderators,
I have been loyal to apple for over a decade. I currently own a 2009 Macpro, a 2011 macbook pro 17", a 2013 macbook pro 15", and a plethora of your gadgets. I have spent over $30,000 on apple products, and to charge me $20 for a phonecall for a issue that is most likely internal, and probably has a relatively simple solution is infuriating... Needless to say, the next time I spend $5-$10K on a studio computer, it will most likely not be an apple unless you resolve these issues. Thank you.

How do you get core audio to work with maverick. I'm using logic pro X

i'm having problem with core audio and maverick

It sounds as if you have altered the Tempo after recording the Audio ( but before selecting +Follow Tempo+ ).
This would make your Regions adapt from the old tempo to the new one, therefore changing their timing.
Here's a bit more info:
Audio files recorded in Logic Pro can follow the project tempo—inclusive of tempo changes—set in the global tracks.
+Note: These audio files can also follow the first key signature set in the global tracks.+
As an example: If you record a bass solo at 100 bpm, you can change the project tempo to 120 bpm and the bass solo will automatically be played back at the new tempo.
The function works with all audio files that were recorded in, or bounced/exported from, Logic Pro.
The function only works in the parent project (the project the audio files were created in). If you drag a file recorded in a given project to another project with the Finder, the file can not follow the project tempo.
Bounced or exported files can only follow the project tempo if the “Add resulting files to Audio Bin” option was enabled in the Export or Bounce window—prior to the bounce or export.
Files copied between two projects retain the ability to follow the project tempo.
The project’s tempo information is used to tag the beats in the recording. The function works best if your audio files match the project tempo as precisely as possible. The longer your audio files are, the more RAM is required for this functionality to work properly.

External display at 1920x1200 causing audio dropouts

I've got my Macbook hooked up to a Samsung Syncmaster 245B+ 24" monitor running at 1920x1200 with the Macbook in clamshell mode, I bought the monitor a couple of weeks ago and ever since I've been having problems with audio dropouts, both with the onboard soundcard and my external Presonus Firefox Firewire audio interface.
It seems the CPU is being overloaded at random, usually when there is some kind of graphical happening in a web browser for example. If I load up a page with a lot of graphical elements on it, sometimes the audio cuts out for a few seconds and then comes back, even then it can come back distorted. I can usually force these dropouts by briskly resizing the browser window, which makes the CPU usage level increase somewhat and thus the audio cuts out.
I first of all put this down to the Macbook not being able to display at this resolution sufficiently, but I have seen no other complaints from people running a 24" external. What's even more concerning is that I can switch the external down to lower resolutions (ie 1024x640) and still get the audio dropouts, which should not be happening as the Macbooks own display runs higher than this and I never get a problem when using it that way.
I've tried creating a new user account and the problem persists. Tried repairing disk permissions (although I knew it would make no difference) to no avail. I suppose the next step would be a complete reinstall of Leopard, but obviously would like to avoid this.
Does anyone have any suggestions as to what the problem could be? Do you think it's just the Macbook in general not being able to handle this monitor or a specific problem with mine?
I hope I can get this sorted, it's really off putting having music dropouts while I am working...
TIA,
Alex

Next time is happens, try unplugging the external monitor, but only the external monitor. Leave everything else plugged in, including any peripherals, like the Personus and also any attached USB devices. If the problem persists, then start unplugging the peripherals one-by-one.
Generally a display should have no bearing on sound since the GPU (X3100) is completely separate from the CPU where sound is managed.
You haven't said anything about your MacBook's configuration but maybe there is an insufficient amount of RAM for the number of processes running. That's another possibility.

Airplay audio stutters from Yosemite, video remains unusable.

I've come across numerous other threads describing this issue but none seems to have a resolution other than "wait until Apple fixes it via update", so I decided to make a post and see if I could find some newer answers since it's been a while.
Upon updating my macbook pro to Yosemite back in when it was released, Airplay audio from my MacBook to my Apple TV 3rd Gen stutters for about 30 seconds after beginning Airplay and intermittently thereafter. With Mavericks, everything worked perfectly and nothing has changed hardware-wise since then, which handily implies that Yosemite is to blame. Still, I have wiped and restored both my macbook and the Apple TV (via usb), and even my router (Airport Extreme ac) in my efforts to troubleshoot with no luck. Wifi conditions are maybe 8 feet with direct line of sight and I've tried both 2.4 and 5 GHz spectra. Video airplay functions after a fashion but has a continuous stutter that makes it practically unusable. Note that this issue also affects my partner's MBP but both of our iPhone 6's continue to function perfectly. The Apple TV is connected to the Airport via ethernet cable.
Other solutions I have come across include disabling bluetooth on the mac, but this solution is untenable as it breaks the functionality of Continuity features which I have come to depend on and also doesn't seem to work for everyone, and several terminal commands which alter the behavior of bluetooth on my system which ultimately have the same adverse side effects as simply disabling it.
I am seriously lamenting this broken airplay functionality and, since it was a key motivator in my use of the Apple TV product, am strongly considering something different. Am I pretty much just out of luck here?

All software current.
Edited to note that the Apple TV was connected via ethernet.

Completely random fix that worked for me - was driving me nuts and like you tried every other suggestion.
I was certain issue was post iMac Beta upgrade to 10.10.3 - reverted back to 10.10.2 and still there - did all the Blue Tooth, router suggestions blah blah blah
Changed to wired network, still there.
I then factory reset Apple TV - while not connected to the network - problem was not present - just playing around in Apple TV basics no issues - happily confirmed not the Apple TV.
Removed wired network, re-added wifi network, de-authorised my computer and then re-authorised and everything has since worked - just watched an hour long show and no issue.
Doing a little jig of joy - off work today sick so wanted the bloody Apple TV working Fingers crossed it works for you.

I forgot to mention that the Apple TV is connected to the Airport via ethernet cable.

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. any soln ?

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing wireless network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. I am using a set of speakers from kenwood connected to the airport express. The operating system on my macbook is mac os X 10.5.8. i am sure it is not a problem of streaming music online because i have even tried playing music which are stored in my macbook.
Is there any problem with the setting in itunes or quicktime ? Kindly reply...... I am waiting for your valuable suggestion.
Thank you a lot in advance.

I am shocked to have found this same AX audio dropout problem starting TODAY, every few seconds the audio just drops for a couple seconds and then resumes: Latest software versions of everything. No iPad, iPhone or Touch. Internet hardwired to D-Link DES1105 (1000baseT Switch) hardwired to new 80211N AX, AX optical to stereo, AX Wi-Fi internet to basic 1st-gen MacBook operating at 80211G, and an older 'G' AX extender at the far end of the house, away from all this. The MacBook streaming iTunes is usually 12 feet from AX. I've used this setup for years of trouble-free AirTunes / Airplay until today. Today I also found 2 very reliable fixes and 1 way to force a dropout, but first, I read some posts and tried ALL following settings one-at-a-time and restored them ALL because NONE of them helped: Turned off IPV6. Streamed to multiple speakers 'Computer' and 'AX' (restored to just AX). Turned off 'Ask to Join new (WiFi) Networks'. Turned off Bluetooth (can't live without Magic Trackpad, so glad that wasn't it). Here's my discoveries: Lo and behold, each time I click the Airport icon in the Menu (you know it shows you've got 4 bars from AX) when the status switches to 'Looking for Networks' for a second it CAUSES the AX audio to drop out for a couple seconds (it never did that before today.) iTunes still playing, streaming, AX laser still lit, but the 'PCM' light on stereo and the sound GOES OUT EVERY time I click the Airport icon in the menubar, just like the regular, annoying dropouts. So, to reduce traffic I quit Safari (3 tabs, no streaming, just Gmail, Google, and Netflix browsing). Lo and behold, the dropouts stopped altogether. No other Web apps going (not iTunes Store, Genius, Ping, nothing), so I launched Chrome to the same 3 tabs and the dropouts HAVE NOT RETURNED. That's right, not only did simply QUITTING SAFARI cure it, and Chrome doesn't contribute to it, but I can demonstrate it just by forcing my Airport to re-scan. Works for me, written using Chrome. The other reliable fix is to hardwire MacBook to the Switch. This is obviously not ideal, but Airplay audio doesn't drop out over Ethernet. Also, in all my tests, it made no difference whether iTunes did the streaming, or Airfoil did.

Logic X - Mavericks - Audio dropout every 20 seconds

Logic Pro X output drops out for about 1 second, about every 18-20 seconds consistently. Brand new iMac, NO fusion drive.
I have tried with multiple output devices including the built-in output. Result is the same.
Audio and instrument tracks behave the same. The tracks themselves still show that they are producing a signal, however the actual output track in Logic shows the dropout.
Updated all software, restarted... no difference.
All instruments, be it Kontakt, Omnisphere, Sculpture... no difference.
Increased buffer size to maximum... no difference. Decreased to minimum, no difference.
Uninstalled Kontakt 5 and reinstalled since I heard it had issues with Mavericks... no difference.
Played other music while hitting playback in Logic - Only Logic audio drops out.
Until a couple days ago I've been working on a 2011 27inch imac with Mountain Lion, everything else exactly the same, no issues at all. Please help. I'm all out of ideas.
System:
Late 2013 27-inch iMac
3.5Ghz quad i7
32 Gb RAM
500BG SSD
OSX 10.9.2

One other thing... I just bounced a WAV file of a session and the dropouts are present in the WAV file too. Very frustrating.

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.

160 Gb Classic - Audio dropouts, gaps on gapless albums with apple lossless

Dear All,
Since getting my new iPod Classic 160 Gb iPod Classic, I am experiencing audio dropouts that last between one and two seconds. They aren't frequent, occurring maybe one every hour or two of audio playback. They appear to be very random. If I play back the same track after having a dropout, it plays fine and doesn't happen again in the same place. This doesn't appear to be connected to my moving or shaking the iPod around, as it will happen when I am sitting down and perfectly stationary. Also, I don't think it is related to a bad earphone connection, as I a have played the iPod with several pairs of new and/or high quality earphones. More info: Most of my files are Apple Lossless and content is primarily regular music albums. Of note, this is the second 160 Gb iPod I've had with the same problems! The first one I brought down to the Apple Store in Ginza, Tokyo and they replaced it in the blink of an eye after I explained the same as above.
Prior to the 160 Gb Classic, I have owned 1st, 3rd and 5th generation iPods (plus a 2nd gen. Nano and shuffle). The 5th gen. 60 Gb was playing the exact same audio files and never had any dropouts.
I have reset the Classic and reinstalled all my music files (with the most recent ipod software 1.0.2 and running iTunes 7.5) twice now, but the problem remains. I am now thinking of taking one of two possible routes of action. a) go back down to the Apple Store and try to get another iPod replacement (and hope and pray that it doesn't experience this problem) or, b) change all my music files to something like 192 kbps and hope (and pray!) the iPod can handle the smaller file size without the dropouts. At the moment, I am leaning towards going down to the Apple Store as it would actually be the less time consuming of the two for me.
What do you wise people out there think? Exchange iPod or downsize my audio files? Or, does anyone have another suggestion or recommendation on how to resolve this issue? Thanks for any assistance.
To add to this, I have also noticed that several of my gapless albums (DJ mix CD's like those by Global Underground), no longer play consistently "gapless". Sometimes it will pass smoothly between tracks and other times there will be a small pause/gap. No doubt, I have checked the gapless album box and selected yes, in the album get info section for all of these albums, but still problems remain. Any suggestions would be greatly appreciated.
Again, my previous iPod, 5th gen. 60 Gb had none of these problems with the same files. I am really happy with the 160 Gb capacity of my new classic but feel a bit let down with these problems I'm having.
Regards,
Peter B.

Thank heaven! I thought I might be the only one.
My situation almost exactly mirrors your own. My first 160GB classic suffered from sudden dropouts, apparently random and almost impossible to replicate in any predictable fashion. For example, I'd start playing an album and would hear a one or two second dropout in the second track, but in attempting to replicate the situation exactly (as in, powering down the iPod, powering it back up and starting over from the first track of the album) I'd find that the fault didn't recur. Restoring and reloading made no difference at all.
So I took it in to the Apple Store and had it replaced, loaded the replacement up with music and was dismayed to discover myself facing the same problem. I too have had several iPods which were loaded off this same library, and none of them ever gave trouble in this fashion.
I think the issue might just be the size of the files in our libraries. The bulk of my files are at 320kbps, and you mentioned yours were mostly Lossless - could it be that the classic has problems dealing with large files? It's a very frustrating issue, since the audio quality of my classic is so much better to my ears than that of my previous iPod 5G.
I recommend that you take the iPod in and take them to task about it. That's certainly what I'm going to do - I really don't want to re-encode all my music, especially considering that I bought this iPod due to the burgeoning size of my library, and re-encoding would defeat the point. Plus, since it has better sound it sort of deserves to be loaded with larger files. I just hope this isn't an irremediable issue, which I'm starting to suspect it might be, since your iPods were obtained in Japan and mine in the UK. I'll continue posting as this unfolds, and I hope you'll do the same.

Why am I getting distortion from my audio interface while using Logic 9 on my new iMac with Maverick?

I have been recording using a line 6 UX2 interface and also, a Focusrite iTrack Solo interface, successfully with Logic 9 on my 2007 MBP for a few years now. I recently bought a new iMac and migrated my time machinre back up to the iMac. Since then I have had to maunually replace missing sound and room evironment files, and now I cannot get a clean mic recording using either interface or either of my two mics.
Any suggestions?
Perplexed in NYC

I assume you have an iMac with a fusion drive? If so, contact Apple. Audio dropouts on these machines even occur in iTunes.

I am not able to see the airplay icon with Maverick. Can anyone help on how to go about this?
