Optical audio drops out intermittently

Hi
Weird problem has been occurring for the past couple of weeks. Optical audio drops out intermittently, for about 1.5 seconds. Playback isn't affected. Analogue audio is fine. MBP is connected to a Bose V20 sound system.
Any thoughts?

IMac Audio dropping out intermittently

I have a 3.4 ghz intel core i7 iMac running Mac OS X version 10.7.5
I currently have a bose companion 5 system as my external audio device. The audio works fine when the computer is started, but stops working anywhere from 2 minutes to half an hour after starting. To make the audio work again, the computer must be restarted.
I have looked all all my physical connections, checked the audio panel in system preferences and the audiomidi setup in utilities. All of those things appear to be normal.
Any feedback or suggestions would be appreciated!
Thank you.
DA.

I got this from "GearSlutz".com
Well, since the USB 2.0 hub still was messing up here and there, I decided to walk down to the Apple store to buy a Belkin Thunderbolt express. Yeah, this solved the problem 100%. Audio interface is finally working as it should. No dropouts at all. Not even once after a whole days work! NICE. So, yeah, if you have $300 to burn, this is a perfect fix.
It seem to be a problem with USB and Thunderbolt. I hope this gets fixed soon, after spending 3k I dont have another 300 for a dock.

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 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.

ITunes scratchy he||...with audio drop outs

I use iTunes v7.4.2 all the time to play music. Only lately my iTunes has been sounding very intermittently scratchy (static-y) and the audio drops out (without the diamond moving) at unexpected intervals (anywhere from 10 sec to several minutes). When I try to hit the volume buttons, I don't get any feedback sounds like usual. Waiting it out seems to be the only remedy...then it comes back again, and again...
I use MenuMeters to monitor my CPU and bandwidth speed and so I notice that this happens most when I am downloading torrents. Very frustrating! Curiously, I tried running a bootable clone of my system on a separate drive and I found that the problem went away (I'd have to run it for longer to be sure though). Could this be a sign of imminent hard drive failure?
Has anyone else experienced these issues? Does it sound like a hardware or software issue?
Thanks for any replies,
-Bill

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.

Audio drops out for about 2 seconds after about 2 hours

Hey folks....I've been renting HD movies, and I've noticed a bit of a pattern. Three times now, at some point just after about two hours the audio drops out for about two seconds. It's not exactly the same time - on one movie it was at 2:02:26 and another it was at 2:04:18. It's only two seconds, so it's really of no consequence. Just now it was during the closing credits (the music). Before, it was that scene in Batman where the two ferries are stalled on the river.
Of course, I would rewind to make sure. I use the optical out.
Anyone else notice this?

Do a hard reset. Hold the power and home buttons simultaneously until the Apple logo appears.

HELP! Audio Drops Out When Trying to Capture Canon XL2 Footage

Please help me out here. I'm a freelance camera operator w/ a Canon XL2 and several times now I've gotten calls from the editors saying they're having problems logging my footage, mainly the audio drops out quite a bit, and I'm not talking bout one second for every 2 or 3 minutes. No. It's like every 10 seconds the audio drops in and out.
What's the deal? Two times the guy was using a Panasonic DVX-100A to capture, another time it was a SONY DSR mini-DV deck. With each incident I had to go over with my XL2 and use it as the capture device, which is a pain.
The program they're using is FCP HD or 5. But I think even when they just play the tape in their Sony or Pany cameras, the audio may still suck.
Help me out here, I can't be the only one with this problem.
Thanks.

Well Robert Swanson, I hope my post wasn't taken offensively, it certainly wasn't meant as such. The only Canon camcorder I owned was the GL1. After switching to Sony's I can honestly say it would take something significant to go back. And, I was merely relating my experiences in trying to capture from other Canon camcorders so that I know where you are coming from. However, I am interested in the HVX being the "noisest" camera on the market. I am seriously considering this camera and would be interested in a review that points this out. I would be using the hard drive recorder instead of P2 cards.

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)?

Audio drops out when following video to external monitor

When I play a sequence to an external monitor, the audio drops out for 2 to 3 seconds after changes on the video track, and then pops back in with no interuption in video output. It doesn't happen at every cut, but it's consistent in the places it does. I thought it might be caused by the size the project has become. So I exported the sequence as a quicktime file, closed the lage project, opened a new one and exported the new file and played it and it happened again, even though there were no edits. It doesn't occur at all when I turn off external video, and play it on the computer. I connected a new firewire from the computer to my DV deck, restarted the computer, but it keeps happening.
Is it that the dramatic change in color, light and compostion crowding out the audios ability to follow the video through the wire?
I'm completely stumped. The next step will be to open the computer and try to blow any excess dust out. I do this periodically anyway, and my last time was two months ago, so I'd be surprised if it works.
Maybe the G4 with 2G processing power can no longer handle the program, but it shows no sign of stuggle in any other way.
My clients are starting to grow restless.

Thank you so much X & Paul, for your suggestions. Although they didn't solve the problem, they kept me hopeful enough to continue my quest for an answer. After exhausting all effort to find the problem in the audio, I decided to focus on the video. So, I tried correcting the excess luma on the consolidated QT movie, and suddenly the problem was fixed. Because of the different levels of correction I'd need for each and every cut in the original sequence, and the precious time it would take, I'd planned to save it for the color correction stage, a mere 2 weeks away. I remembered how illegal white would often cause the image on some monitors, specifically consumer TVs, to waver for a second. But this was happening all the way back to the DV deck's audio meter, so I never expected it to be a luma issue.
I assume that the outdating capacity of my G4 played a part, but I wanted to write back with my thanks, and to impart my illuminated wisdom to the next perplexed soul.
Thanks again,
jesterhead

Video & Audio Drop Outs on Macbook Pro

I have a MacBook Pro with Version 10.7.3, 6 months old. Just recently when I play video, regardless of whether it's in iTunes, iMovie, or embedded in Keynote the video sticks, audio drops out for 1 -2 seconds or the shot freezes. What causes this and how is it fixed.

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.

Is itunes 8 fixed (audio drop out)?

itunes plays fine for a number of tracks and then the audio drops out completely at the beginning of a new song despite the interface appearing to be playing as normal.
This was the major pain - even though it only took a pause and restart to get the audio back - it happened so frequently. I should point out that this may be related to my airport Express network, but it went silent on both my external speakers and my computer.
I found a number of posts outlining the same problem but no solutions that worked apart from one great one (sorry, can't find it now) which confirmed it was a problem with itunes 8. True enough, after exhausting every other avenue, i have reverted to itunes 7 and the problem has disappeared.
The problem is that I have lost many other upgraded features so can anyone advise me as soon as this issue is resolved in a more up-to-date version of itunes so I can upgrade without the problem returning.

Unfortunately, this is a known problem which Apple seems to be brushing under the carpet. Communication problems using Airtunes has been affecting a lot of users here. Try following the procedure outlines in the sticky of this forum entitled ' Solutions for AirTunes Issues in iTunes 8', and hope for the best. If that doesn't work, I guess you're in the same boat as the rest of us, and will have to wait till Apple sorts out this problem.

IDVD '08 Slideshow Audio Drop Out

Hi
I've recently upgraded to IDVD '08 & produced a slideshow of 301 pictures with music. I get a moments audio drop out at each 100th picture. I know this to be a problem when the disc is played on a DVD player, but not on a computer. I had hoped that by upgrading to IDVD '08 the problem would have been eliminated. Can anyone advise if there is a way of solving this issue, other than producing separate slideshows of 99 picture & less.
Any help would be much appreciated.

The behavior you described above is actually normal for iDvd for anything over 99 images per slideshow. Not much you can do about it short of creating multiple slideshows as you mentioned above. That or making your slideshow as one long QT movie but you may notice a quality loss.
Or you can try a few other apps like:
http://www.boinx.com/fotomagico/overview/
http://www.lqgraphics.com/software/phototomovie.php
Roxio Toast has a slideshow option as well. You might want to look into this.
DVDSP might give you slightly better results but then again it's much more money and takes weeks/months to learn as opposed to a few hours / days.

Audio Drop Out

No matter how many minutes of audio or photos (believe me I tried from 2 minutes to 25 minutes of audio and 10-150 photos) that I use in DVD 6, the audio drops out for 3 seconds, always about 1 minute before the finale. Is anyone having the same problem.
I tried magic slideshow, all combinations and still...audio drops out.
When I used the 99 photo limit with the fit to audio minutes, nothing like this happened.
If there is a fix, please let me know.
Thank You all

Welcome to discussions, Bob:)
What is the source of the audio where the drop-out occurs? Purchased iTunes?
If so, burn the audio to an audio CD and import from that.
Also, how much free space do you have on the iBook?

Audio Drop out @ every 2 seconds

Having issue with the Audio dropping out every @ 2 seconds, indepentant of source (local, sync'd computer and web trailers). Have done factory reset, still doing the same thing. AppleTV is connected to the TV through HDMI connection.

Try turning your tv (not tv) off and on.
