Digital Audio Cuts In and Out
I have an earily 2009 Mac Pro hooked up to my Onkyo TX-NR3007 via digital audio (optical TOSlink). When I play a movie or music it cuts in and out. Maybe 30 sec of sound than nothing for a few seconds then sond again. I have tried 2 different cables. It is not the media because it does not happen in the same spot twice. I have also tried a differnet opt in on the receiver with the same results. I'm running up to date OS 10.7.5,
Please help I've tried everything I can think of...
Even after switching DD to "On" switching cables and ensuring that I was playing back audio content with DD encoded audio, I still receive no DD audio and continue to get audio drop outs.

Optical digital audio cuts in and out
I am connecting my new Apple TV 2010 to our Bose Lifestyle 28 (Apple TV HDMI to VS-2 and Apple TV Optical Digital to the Bose Lifestyle). After power cycling the Apple TV the audio works but cuts in and out every few seconds.
All thoughts appreciated.
Thanks in advance, JayEven after switching DD to "On" switching cables and ensuring that I was playing back audio content with DD encoded audio, I still receive no DD audio and continue to get audio drop outs.

Mac Mini 10.7 external hdmi audio cuts in and out
I have the newer mac mini, have had this one and another one previously setup on my samsung TV through hdmi then fiber to polk audio soundbar has been working fine on 10.6. I upgraded to 10.7 and now the audio cuts in and out. When i go to audio and set it to internal speaker it works fine. I didn't have any issues before the upgrade. I did swap the hdmi cable with the one from my ps3 since it isn't cutting out, and it still cuts out on the mac running 10.7. Ideas?
Same issue here, and same fix. PRAM reset... twice! I actually held it down TOO long and it tried to prompt me to reinstall my OS which scared the crap out of me, but I just clicked the "reboot" button on the setup screen and it booted fine. Audio problem gone. Thanks!

Audio cuts in and out on iPhone 4S
I have an iPhone 4S (16 GB) that is on version 6.0.1. My problem has to do with sound cutting in and out when listening to music, using apps or watching videos (audio never cuts out on actual phone calls). The issue happens both when I'm streaming online and using local programs (like apps or iTunes). The music plays anywhere from 15 to 45 seconds, then the audio cuts. The volume bar disappears and the iPhone pauses the muted music 3 to 5 seconds after. If you hit Play again, it works for about 3 to 5 seconds before cutting again and automatically pausing.
Is anyone else experiencing this issue or have heard of it reported? I noticed this issue on my device four days ago.Hey Fitz,
I was just in to the Apple Store to have the same issue looked at for my iPhone 4. Audio cutting in and out across programs, headphones or not, with the volume bar dissapearing when the problem occurred. Turns out its damage to the audio processor (evidently located near the speakers). Can be from water damage, wear and tear or as simple as dust. I had to replace mine outright, but the employee was saying sometimes they just need a cleaning. Worthwhile having it looked at.
Sorry there isn't an easier fix! -
Logic Pro X Audio cutting in and out
When I am trying to record in Logic Pro X the audio seems to cut in and out at random points.
I have a MP3 track that I am recording to and it just randomly cuts out. Even when just playing that track by itself the same thing happens though never at the same spots. If I open the MP3 in Itunes or Quicktime there is no problem with the track.
As this seriously messes with the time of the piece and makes the recording long and painful I need help.
Is there some type of connection I am missing? I am using an old Presonus Firebox as an Interface, it unfortunately has adaptors to take it from firewire to thunderbolt. Recording into a 27" Imac that is very souped up and shouldn't have any problems until I hit a hundred tracks or so and I am only trying two.It's most likely the Fusion drive, one of the symptoms is audio cutting out.
There are several related threads in this forum regarding audio problems with the Fusion drive.
This thread alone would take a couple of days to read.

What are the iTunes digital audio levels in and out
I am having a lot of trouble with finding out and setting the audio levels in and out of iTunes.
Digital audio has 16bits at '1' with an analog signal level of +12dB, 24bit has all'1's at +18dB. Making the overhead capability for CD 16bit 12dB and that for HD 24bit 18dB.
I would like to record (using SoundStudio) a set of standard audio tones from 20-20kHz with digital levels of "all 1's" 16bit, or +12 dB analog level, "all 1's" 24bit ditto, and the same for levels of analog 0dB (-12dB digital) for 16bit and 0dB(-18dB digital) for 24bit.
What I am finding is that if I get Sound Studio to inert a tone at what it calls 0dB, save it as AIFF, then the output it from iTunes I get a much higher level, around +8dB or so!
Any ideas?As an addition to my first question. I asked the makers of Sound Studio about levels. They tell me that the Mac standard is to have all '1's in the digital stream defined as 0dB.
Which helps as I can now record a tone at the CD level of -12dB and the HD audio level of -18dB. And if I make recordings I know to keep the input levels well into the green, not yellow and definitely not up to the red.
As you say the output of iTunes is boosted, and from my measurements this boost is in the analog circuitry and is about +8dB.
I woul dnot recommend turing down the iTunes volume control as this brings in the digital volume reduction, which depends on the algorithm they have implemented. This is not so bad for iTunes as the Audio Core software works at 32bit and can handle 16bit volume changes fairly well. But on the iPad it is different as iOS is only 16bit audio so the volume algorithm is poor. So always leave the volume at maximum and turn down your HiFi volume control!
Or use a digital output to an external DAC as the iTunes volume control is then disabled. Set Audio MIDI for 24bit output and you are ready to go with HD Audio. -
I have had major issues in the past six months with the audio from my AirPlay where there used to be none. For a long while I used an elaborate setup from my 2nd gen AppleTV, to a optical audio out to a quarter inch converter to an AudioEngine wireless dongle to my receiver with flawless results between 2013 and late 2014. When problems started occuring I naturally figured it was the wi-fi network, I did some serious reconfiguring to get as strong and clean of a wi-fi signal as possible, still had the issues. I finally decided to simplify the whole setup to an AirPlay compatible Denon AVR-x1000 stereo that hardwires to my wireless router. All was good for a week, now its worse than ever, even resetting the internet and the router will not seem to get the AirPlay from cutting in and out. I have an iPad, an iPhone 5 and a Macbook Pro, and an AppleTV all connecting to the receiver. All have the same cut in and out problem that existed before the receiver and after. It seems every update makes things less stable not more. Is there someone who can help walk me through a fix or just tell me AirPlay no longer works so I can stop trying?
Please help!!!
Here is my setup -
Macbook Pro 15-inch, Mid 2012 - 2.6 GHz Intel Core i7, 8GB RAM Running OS X Yosemite 10.10.3 connected by Wi-Fi
Denon AVR-X1000 AirPlay enable receiver connected directly to router via ethernet
Netgear Dualband Wireless-N Router WNDR3700 - 2.4GHZ Channel has a 92% Signal and the 5Ghz has 85%
Internet Connection is fast and consistent 72MBps Down 10 Up
2nd Gen AppleTV connected via Wi-Fi
iPhone 5 iOS 8.3
2nd Gen iPad running iOS 8.2
I have shut off bluetooth on anything that has it to avoid interference. The video of the appleTV works just fine and the Airplay Icon is consistently available, this is an AUDIO issue.
***There is another 2nd Gen Apple TV in a separate room (weaker signals all around) connected to the same network that works flawlessly streaming audio and video from any device.***Hello Mikeh42,

Audio cuts in and out on burnt DVDs
Hello here is my problem, I hope someone can help me because I'm already behind my deadline for this project.
I exported a Quicktime movie (version 7) from Final Cut Xpress and imported it into iDVD 4. When I preview the movie everything is fine. When I burn the DVD most of the movie is good except at near the end the audio cuts out completely and then returns several minutes later.
The audio is fine when I watch the QT movie. When I burn a DVD then it cuts out.
I've tried a few times with different settings and the same thing happens at the same moment in the movie. I tried burning just the troubled section of the video to DVD and it had no audio either.
Why would this happen? Why is it all good when I preview the DVD in iDVD but then goes to **** after I burn it? If the source file seems intact when I view it in QT then where is the problem?
I have a stack of coasters from burned dvds all with the same problem at the same place.
What am I doing wrong?What was the source of the content you assembled in FCX?
The audio is fine when I watch the QT movie.
Is it a self-contained movie or a reference movie? (a self-contained movie will be many MB in size while a reference movie is just a few KB.)
Why is it all good when I preview the DVD in iDVD but then goes to ** after I burn it?
It's because the preview function of iDVD just runs your source material so you can see if things are linked in the way you want. If the original files played in QT, they should play in preview.
I tried burning just the troubled section of the video to DVD and it had no audio either.
Open the movie clip of the troublesome video in QT player and do: Window>Show Movie Info

ITunes 9.0 audio cuts in and out sporadically
Installed iTunes 9.0 recently and haven't noticed this problem before but when browsing on the web, navigating directories within the hard drive, etc., the audio cuts out briefly intermittently.
I thought this might have to do with running too many programs at once with 4GB of RAM but even if I scale back on programs running, I do not notice any difference. I recently installed Norton 360 and thought that might have something to do with it but not sure.
I don't notice the audio cut out like that anywhere else.
Anybody else notice this?I don't have my iPod docked when I have this problem. Downloaded 9.1 today, thought it might help. No. It's as bad as before.
My system is good, no defrag needed. Though I like to run that every so often. Like spring cleaning for the computer, even if it doesn't need it, heh.
Looking for something else to use to manage my music, since iTunes won't cut it anymore. -
Audio Is Randomly Cutting In And Out In Playback
I have encountered this problem on all recent Premiere projects I've worked on with a variety of audio types. My audio is cutting in and out in a seemlingly random way while the video keeps running fine. Sometimes the audio will play fine for 15 seconds then stop, sometimes it stops and starts after about 2 seconds. I have tried adjusting all of my preferences, settings, audio types, and even video types but the problem always comes back. Spoke to a friend who's new to Premiere and he's having the same problem. Considering moving back to FCP despite the weak interface.
Currently I am editing Canon 5d Mkii footage at 1080p, 29.97 fps. I am using none of the audio attached to the video clips - only editing to a separate m4a music track. My audio is at 44100 Hz. I am playing back video at 1/4 quality. I am running a fully updated Mac Powerbook with a 2.6GHz Intel Core i5 and 8gb of RAM.
Please help, almostly completely unable to edit. Thanks.I am still having the same issue in Premiere CC 8.0.1 (21)
Exact same issue as the original poster on this thread, as well as the original poster on this other thread:
Premiere Pro CC Audio Cuts Out
So this audio issue persists from version 7 now in version 8.0.1!
For me, audio is cutting in and out randomly and never in the same place. If I have multiple audio tracks on the timeline, then one or more tracks might drop-out at the same time. Sometimes all tracks drop out at the same time. It seems completely random.
I am editing with a combination of P2 footage and DNxHD 290 footage. (I originally had some AVCHD footage, but then I transcoded all of it to DNxHD 290 -- but this did not improve the audio issue at all.)
Two of my audio tracks contain the native camera audio (stereo); 1 track has the music bed (stereo .wav files) and 1 track has sound effects (stereo .wav files)
In one of my projects, I had a very strong reverb effect applied to the track (not to the clip). When the audio dropped out, I could still hear the tail of the reverb. This leads me to conclude that it's not the entire audio track that is muting -- it's definitely the source audio clip that's dropping out. The reverb tail continued after the audio dropped out.
Playing the same part of the timeline again produces randomly different results -- audio might drop out on a different track, or at a different time, or not drop out at all.
This bug is making it nearly impossible to edit! I have filed a bug report at http://www.adobe.com/go/wish_fr
During timeline playback, my CPU utilization never goes above 15% and at least 12 GB of RAM is staying free, so I am pretty confident these drop-outs are NOT caused by lack of computer resources. Also, my hard drives seem to be fast enough to play back 4 streams of HD simultaneously, but I am getting these audio drop-outs when playing back 1 stream of HD plus 4 channels of audio. Therefore, I don't believe this can be a hard drive bandwidth issue.

Windows 7 64 bit, SP1
RAM: 24 GB
CPU: Intel Xeon X5680 @ 3.33Ghz (12 threads)

I tried facetiming for the first time and my audio kept cutting in and out.. WHY!? It was so annoying. Does anyone know what might be the problem? Connection? Thanks!
Do you have a Corp. Exchange account on your phone? I ask, because the requirement to encrypt an iPhone backup can be enforced by a profile installed on your phone when setting up the Exchange account.

Sound cutting in and out on Macbook Pro 15 (original) when waking display
When I wake the display from sleep, any audio that was playing when the system went to sleep - or rather, the display went to sleep (ie: pandora, QT movie, etc), immediately starts to cut in and out and gets glitchy. This happens as soon as I move my mouse and get the dialogue box to enter my un/pw to wake from sleep. The only way to resolve it is to quit the application putting out the audio, and then open it up again. Once I do that, the problem goes away.
Currently running 10.6.2, but have had this problem since upgrading to Snow Leopard. I've searched the forums and can't seem to find any answers. There are a lot of vague sound issues with MBP and this is a hard one to "sum up" in the subject line. Any help would be appreciated. Thanks.I've searched the forums and can't seem to find any answers.
Not even quitting out the audio application prior to letting your computer sleep?
Not sure what you have already tried from searching the forums. If you have Applecare, give them a call or take your computer to an Apple store. Let the Geniuses there check it out.

Digital Audio In to Line Out Not working.
How do you route digital Audio in to Line out? I have a 2010 Mac Pro, running digital in and have validated it's a good signal. No sound through the line out.
In the interim, i've used Audio Hijack to route it through the line out with no issue. I'm confused as to why i must use this 3rd party product to route the audio. Any ideas, this can't possibly be a new problem.
Thanks!I've had problems connecting my computer to my cable box as well. Comcast apparently disables some of the functions on its boxes. Call your cable company. It's most likely a problem with your box, not your computer.
Good luck and if you find the problem let me know. -
I am running Mainstage 3.0.3 on my MacBook Pro - 13" (early 2011), OS X 10.9.1, 2.3 GHz Intel Core i5 processor, 8GB RAM and running on a Samsung 500GB SSD drive. I am plugging in a bass through an M-Audio USB Fast Track.
Using this right now simply to play along with tracks on iTunes (for practice). Used to use Garageband for this, but then I got Mainstage. Mainstage 3 was running fine when I first bought and downloaded it. Not sure what the problem is now, but when I open it and create a new concert (bass-rig) then turn the master volume up, the slider movement is choppy and the sound/signal cuts in and out (more out than in). The only time I can get sound to consistantly come out is if I click on a menu option, like File or Edit or Action, etc... if I click off the menu, the sound cuts back out and I get nothing.
Sound works perfectly fine through Garageband with the same setup.That's the model of your processor in your HP P6350z. Do you have a discrete (separate) audio card in your PC? When you purchased your PC did you add a separate audio card? If not, then go to www.realtek.com and download and install the latest audio drive for the Realtek ALC888S.
