Audio drops, or playback pauses

Audio drops or the playback pauses after about 5-10 minutes for iTunes purchased/rented content only. Rewinding the show/movie a few seconds back and restarting it will give another 5-10 minutes of playback before problem recurs.
Streaming from Hulu or Netflix is not an issue.
The problem is regardless of time of day, or whether WiFi or ethernet wired connection. Am current on software updates, and this is an AppleTV gen 2. I have rebooted the AppleTV, but have not reset to factory settings.
The problem did start a week or so after applying the last software update.
Any thoughts on a solution?
Anyone else having this problem?
-thanks

Thanks Tom - I have a fairly new iMac 27 and beefed up the graphics with all the extra memory I could get and it seems to handle importing from tape and doing other tasks well - am only using a browser and skype for meetings.
I'm surprised you can't turn off the audio (or the video) during playback - this post seems to say it was possible in Final Cut Studio https://discussions.apple.com/thread/1963460?start=0&tstart=0
I get that it has to be playing back to capture but surely it doesn't have to show it to me or make me suffer listening to it an hour at a time. With 50 plus hours of tape to capture I might have to only do this of an evening as I need to work with audio available during the day.
Thanks for replying and letting me know it's not possible - it's really appreciated.

Audio dropping out during playback in timeline

Hey everyone,
I've dug through these forums and unless I just completely overlooked it I have not found a solution to this issue. I've listed my setup below and then have stated the issue I'm experiencing.
27-inch, Mid 2011 iMac
3.4 GHz Intel Core i7
16GB 1333 MHz DDR3
AMD Radeon HD 6970 1024MB
Running Mac OS X Lion 10.7.5 (11G63)
Currently working off of a portable 1TB G-Technology G-DRIVE via FW800.
Working in Premiere Pro CS6 Version 6.0.2
Editing in a sequence with settings:
1920 x 1080 23.976fps (also tried in a 29.97fps timeline with same issue)
Working with footage that is 23.98fps
Working with a combination of ProRes 422 (LT) and native H.264 Quicktime files strait from a 5D Mark 3.
The issue I'm having is during playback the audio will competely drop out. The video will continue playing on just fine but the audio drops completely out. All audio levels drop as well in the audio mixer meters so it truly is losing all communication with my audio layers in the timeline.
I read in other forums to go into Finder and delete out the .caf files, re open Premiere Pro, wait for them to be recreated then carry on. I tried this approach with no luck. Deleting the .caf did not change anything. Audio is still dropping out as I try to play through my timeline. The only way to get the audio back is to pause then press play again. I have 5 total channels of audio with only 2 of those channel active.
Any ideas on what is happening would be greatly appreciated. This is incredibly frustrating have to export out a video just to be able to watch it through.

Having this annoying problem also. Using the Space Bar to play timeline it takes pressing and holding to a count of three or trying press play three time in a row using the space bar to get ungarbled audio, or any audio at all in a normal uncomplicated sequence on the timeline.
Really annoying. Audio used to be so simple and untaxing to a sequence.

Playback Audio Drops in Adobe Premiere CC 2014

Hey, my playback audio drops in and out, as well as switches from left to right speaker, every few minutes. Does anyone have a solution to this? This is really harming my workflow,

I have had it happen in two separate projects now. If I go five or six autosaves back then I can open a project that works okay, but at that point there are time consuming edits that are missing.
I just tried importing the corrupt project into a brand new project and it seems to be working okay, but I'd like to prevent it from happening again.

Playback pauses and audio sync issues with live video stream

I'm seeing playback pauses about every three seconds and audio sync issues with our live demo stream when using the OSMF/Strobe player. It happens on both our 2Mbps 720p stream and our 480p 750Kbps stream so it does not seem to be related to higher resolution/bandwidth streams. It also happens if I point directly to a stream asset or if I point to a .f4v with both streams listed for dynamic so it does not seem to be related to dynamic streaming specifically.
The same live streams play back very well without pauses or audio sync issues in the Akamai's dynamic player and even slightly better with JW 5.2.
I have viewed the OSMF/Strobe playback on three different laptops of various age (3 months to 2 years) and two are Windows and one is Linux. I have also tried the various buffering options on the Flash Media Player Setup and Strobe setup and it has not made a noticeable difference.
To see the stream with the Akamai player, go to: http://live.kulabyte.com
To see the stream with the OSMF/Strobe player, go to: http://live.kulabyte.com/osmf
I do not have JW set up for public viewing yet, but the two above show the distinct difference.
We are really hoping to start pointing our customers towards the OSMF player because of the support provided by the community and Adobe, but we have to get the quality of the playback to be acceptable first.
If someone has ideas on debugging I can PM the actual video assets to you.
Thanks,
Tim

Hi Tim,
You need to add this setting:
dynamicStreamBufferTime=8
The actual value can be higher or lower. The best practice is to use a value that is twice the keyframe distance. Anyway, try different values and see which performs the best for your content.
I know that the setup page does not contain this option and it is not documented in the UserGuide. We simply missed it. Sorry.
Also note that the dynamic buffering algorithms are not being used for dynamic streaming content. I tried to explain this here:
https://sourceforge.net/adobe/smp/wiki/Dynamic%20Buffering/
Looking forward to your confirmation that this solved your issue.

Video playback slow and audio drop out after render

Hi
I have downloaded a trial version of After Effects from the cc,
Problem is everytime I render ou,t the video playback is slow and the audio drops out
This happens with AVI or Quicktime files.
Using a Intel i5 quad core, 8 gig of ram 250 gig ssd.laptop
Render/export in Premire pro is fine.
Can any one help.
Regards Phil Green
Blue Room Media.

It sounds like you might be hitting the space bar in hopes of getting real time playback. Sorry, but AE doesn't work like that, because it does totally different things from an editing application like Premiere.
And if you've downloaded the tryout version, you really ought to learn how AE works... and a short description is "it doesn't work intuitively". You can frustrate yourself in a hurry.
But this can really help;

Audio drops mid recording and/or playback

I recorded a video on my 3gs phone last night and it isn't that long, maybe 4 minutes in length. I was able to upload to my computer and when I went to play it back the audio drops halfway through. I checked on my iPhone and the audio drops out there as well. Anyone know why or how this happened that when I'm recording something the audio just stopped being recorded while the video was still recording?

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:

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)?

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.

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?

Bad cable?

One or more frames were dropped during playback???

I have finally complete my movie.... now when I play it back there are two clips which produce this error message:
"One or more frames were dropped during playback"
It tells me I can:
"Turn off unlimited RT" (which is off)
"lower compression data rate" (no idea what that is)
"Close open sequences" (but Im working with the only one open)
"lowering preference for real-time audio tracks" (??)
"increase speed of system..."
Any suggestions on an easy fix? The clips worked before... I think it was when I added a transition that they stopped working. I took out the transition but nothing changed. I even tried to delete the clips and recreate them from the original source saved on my comp. Thanks in advance!

Sounds like your drive is fast enough? Are you playing back rendered material or unrendered? Are you using Unlimited RT or Safe RT?

Video Freezing, Audio Drops and Numerous Reboots

Last night trying to watch the National geographic HD channel at 8:00pm I got that horrible video freeze (again) that would occur ever 5 secs or so plus audio drop outs and pixelation. I already had a tech out to check this out and he said all the levels at all my DVR's are just fine. I unplugged the DVR and rebooted it a few times within the hour show to be able watch the show but to no avail. Also, major "lip sync" audio lag on NBC HD until I rebooted. I have (3) 7216 DVR's and I am getting sick of having to unplug them and reboot several times a week not to mention the constant audio drops (2 of them) every time I come out of a fast forward, rewind or pause. They say IMG 1.6.1 or 1.7 will fix some of these problems but my family is really getting fed up with the problems.

Preview Files Suddenly Go Missing, Render Entire Work Area Crashes Premiere, Audio Drops Out

I opened a Premiere Pro project I was working on earlier today and it said it couldn't find the preview files, searching my system found that the files didn't exist.
Rendering my entire work area brings up the "render window" but nothing happens, if I press cancel Premiere freezes.
Started getting a strange situation error ( 26 ::139 ) in After Effects at the same time that Premiere lost the preview files and the crashes started happening. It disallows me from editing any dynamically linked projects. In Premiere the DL's just show up as "Media Pending" clips indefinitely. Importing the compositions in AE into a new project didn't fix the issue either.
The three problems above started happening all at the same time, was working through a color grade using Red Giant software when it started happening.
Also audio drops out on playback randomly in Premiere Pro, tried various audio drivers and hardware, none entirely eliminate this problem. Sometimes the audio will cut out and "burst in" distorted very loudly, which is disturbing, even when my work area is rendered. This problem has been around since I started using PP CC.
I can provide more info soon or if people want more info pls let me know, I'm very tired and I need to get this issue resolved for tomorrow, in the mean time hopefully someone can point out a general fix for these errors or knows a few workarounds. Tried reinstalling PP and AE, no luck.
Computer is a Windows 7, 64-bit. i7 950, 12gb RAM, GeForce GTX 650, programs installed on a separate internal HDD, media files on another internal HDD. But these same issues (minus the audio dropouts) was also cropping up on a core 2 duo 13'' macbook pro.
Regards,
Zach

Hi Arjun, thank you for your help.
Though that didn't work either. At least the timeline will playback but as soon as I try to render my work region or export any video Premiere freezes.
I removed all dynamic linked files as well, that didn't seem to change anything.
Something I noticed -- the render bar on the timeline that is usually yellow for edited clips that have no FX on them is all red, nothing is yellow (or green). This is a 4 minute long edit on a music video, nothing extraordinary.
I tried creating a new project and dragging a few clips in and editing them, everything went normally and I could render and export the clips. Just any rendering done on any version of this music video edit I'm working on crashes the program.
Also recently had a problem where I opened the music video project and the song that I imported (.mp3) all of a sudden has no waveform or sound coming from it. Dragging it back into the project doesn't fix it either. Workaround was using a .wav copy of the song.

FME audio drop down list issue

Currently FME only lists my recording devices (microphone, line in etc... I do not have stereo mix) and none of my playback devices (Default audio devices or any other), was it intentional that the only way to stream audio from my PC is via use of stereo mix or is my installation just messed up.
Also windows 7 makes stereo mix irrelavent (listen to device feature) so it would be nice to have playback devices listed in the audio drop down list if the guys at adobe intentionaly made it so only recording devices were usable with the program.
If this is just an issue with my install dont reply with "reinstall" I already have, so at this point to get it working if it is indeed just an issue on my end is to reformat and reinstall windows
Also running windows 7 ultimate 64bit, sound card is the default card rolled in with the Striker Extreme mobo.

You can use a line-in cable and provide the sound card output to the line-in input.

Preview in iDVD fine, audio drops off in data image or burned DVDs

Playback in Final Cut HD Express and iDVD preview works perfectly. I create a DVD image and the audio drops out the last minute of a 39 min program. The movie file source in iDVD is DV/DVC Pro. I did a Quicktime conversion from Final Cut using High Quality H.264 and the audio remained but the quality was awful. I did a program info in iDVD and the DV movie did not eat up too much space in iDVD so that's not an issue. I have 28 avail. GB in my external drive where the project is located so not an issue.
I have 23 GB left in my internal drive so that wouldn't be an issue either.
The Apple Store techs were stumped.
The audio that goes missing in the data image and a DVD I burned was a fade out done on Final Cut. There is a blue line on the timeline, but if that was an issue then it wouldn't play back in iDVD. It DOES play back perfectly in iDVD. Somewhere in the conversion from iDVD and a data image or DVD messes with that audio. Any hints?

No definite suggestions, except for things to try (might they count as hints?):
Before exporting from FCE, did you mix down the audio? (Sequence>Render Only>Mixdown).
Did you export a reference movie, or a self-contained movie? Whatever you did, you might try the other.
What versions of FCE, QuickTime, iDVD? Some recent QT updates have caused strange things to happen in older versions of FCE.

Audio drops and comes back out of sync but dvd preview ok

hi All,
i put some photos and videos together in idvd project. The used one of their standard sound tracks to give the background music. The preview looked great so i burned the dvd but to my surprise when a particular video played around 8 min into the dvd the audio dropped and came about a min later with other photos getting it totally out of sync. I have tried removing few photos before that video comes to shift the video's location, there is a minor effect, it playes the clips audio in sync for slightly a sec or two longer but then drops and come back out of sync when it is showing still photos.
thanks in advance.

We have heard nothing about any changes in Encore for CC. I would be very surprised if anything fundamental, like the preview engine, has changed. We really don't know what is still the old sonic authorcore, what may have changed but is still sonic, and what is Adobe created. I have always assumed the preview is sonic.
Is the audio sync issue Bluray only, H.264 bluray only, or any particular audio formats? I don't recall getting the issue in Encore DVD playback.
