[Bug] Playing stream audio from the editor almost always starts from beginning.

Jul 10, 2013 10:37 AM

Tags: #audio #bug #timeline #flash_cc

Whenever I am creating a movie clip with an audio layer set to "stream" I usually click certain points of the movie and hit enter to see and hear it. In Flash CC however, it seems about 95% of the time no matter what frame I am on when I hit enter the audio starts from the beginning and is not in sync. There have been a few cases in which the audio started at right frame but I haven't yet been able to isolate the process. Audio works great in the exported SWF, this issue is just just with the editor.

    What OS?

     

    Can you try leaving the timeline head at the desired position for a few seconds (or something extreme like 10 seconds) and then hit enter, see if you can reproduce getting the correct audio every time? I experienced that on Windows a few times. I've since added a sound blaster (for other reasons) and noticed it's a lot less if almost never. I chalked it up to being similar to video where the audio needs a few seconds to render the correct audio up to that position due to the way lossy compression works. I really don't know if it's uncompressed under the hood in Flash CC.

    Windows 7 x64. I waited a good 10-15 seconds and it still started from the beginning. Editor audio playback is flawless in CS6.

    I had the same problem on a hp desktop system equipped with Windows 7 64bit and a Beats Audio Experience Sound Card.

    I solved the problem by disabling the feature Beats Audio from the control panel of the driver.

    The problem is clearly linked to the sound card playback driver.

    Try to disable any advanced driver features (such as surround sound, improved bass, etc)

    I hope I was helpful.

    That would make sense, I just have a generic dell machine at work. I wonder why sound card support would differ from cs6.

    Having the same issue. Has there been any other solutions to this or is Adobe working on fixing the bug? Going to keep using 5.5 till it gets fixed.

    Hi.  Same issue here.  Windows 7 64 bit, "Realtek High Definition Audio Driver".

     

    It's making animating to audio very difficult.

     

    Also, why can Flash CC not export audio?  I time my audio stems in Flash and then export as a .wav for use in a separate editor.  So, the lack of this feature makes Flash CC useless to me, I'm really sorry.

    Audio is mostly overlooked because Realtek has made onboard so compelling. Back in the day nobody would be caught dead using crispy crackly onboard audio, everyone had a Sound Blaster. I'd consider a couple things first.

     

    Reaktek, as good as it may sound, is a CPU-sharing chipset that unfortunately steals a smidge of power from you to operate. Most of it goes unnoticed until you really care about audio fidelity and performance, such as a studio. Flash, being a multimedia engine, still has to perform code, the display list AND audio at the same time. This is CPU intensive. It's no wonder Realtek is falling a bit behind and it would really be nice to know if this problem stems simply from underpowered systems running onboard audio.

     

    If you're experiencing trouble and use a computer under at least 2GHz intel quad (any i-series) or 3GHz intel dual (again any i-series), speak up. AMD under a hex core with this product may also be in trouble.

     

    Second, Beats Audio is a software product that tunes your hardware. Just Dr. Dre's shot at an EQ. It's no wonder disabling it helps. It intercepts your audio stream and tries to EQ it, which requires system resources. If you have Beats Audio enabled and even have a sound card that offloads audio processing I would still recommend you disable Beats Audio while developing. It's not realistic to expect the same sound on a clients computer anyhow.

     

    The bottom line is Flash CC is the latest. If you load CS5.5, CS6, etc products on your machine and you notice they're starting to lag you a bit such as Photoshop then it's simply time to update hardware to match the updated software. Otherwise, use the generation of software designed for your hardware.

    Hi Sinious,

     

    My PC is a couple of months old, i7-3770k 3.5 ghz.  Never heard of beats audio.

     

    Also, no issues with previous trials of flash or any other application.

     

    Thanks.

    The beats audio comment was for reply #3.

     

    That CPU is fine, how's the rest of the system? Are you also using onboard audio or do you have a discreet audio card? Also you're using a 'k' processor so I assume you're aware that's an unlocked chip so you're most likely not using onboard Intel HD4000 graphics. Are you also using a discreet video card?

     

    The thought path is the same. While the CPU is fine, if you're using onboard audio and video (both of which use system RAM over the FSB and are very slow) it can quickly cripple even that processor.

    The rest of my system: 16 GB ddr3, nvidia gt 640, onboard realtek audio.

     

    Why would Flash CC, alone among programs, including older versions of flash, have audio issues?

    The scene rendering engine is brand new, 64bit. It's apples to oranges over the previous engines. Every previous version has been a 32bit rendering engine.

     

    Good to know you're on Realtek audio as well. Over next weekend when I get time I'm going to uninstall my sound card and see if my onboard realtek performs the same, then reinstall and see if it goes away again. At least it's shedding light.

    Hi Sinious,

     

    I do not think it is the onboard audio.  When I open older projects I find that the audio sounds fine and it plays correctly on the timeline.  Yet if I import a new wav, even into those old project files, the fidelity sounds poor, as if its playing it at 22000 khz.  And it sounds poor when exported in swf format too, even if the publish settings are set to 128 k quality.

     

    Perhaps it is something to do with the importing process.

    The debate can extend in any way, such as the format, libraries used to en/decode, realtime playback libs, etc. I'd love to narrow it down.

     

    I launched CS6 and CC with a mp3 file, set to stream over 8000 frames @24fps default (CC music factory, seemed appropriate ). The darker interface is CC for clarity. I took out my audio board and used onboard realtek with a 2010 driver (latest for my older SB Intel P67 board).

     

    I played the audio from around (random) frame 2114 on both CS6 and CC. I didn't bother showing CS6 play it perfectly over and over more than a few times, it never glitched. I did manage to get CC to start playing the wrong thing however. It played fine a few times, I scrubbed a bit, no real issues. I then typed in frame 2114 and it began playing the wrong thing at 1:25 in the video.

     

    I scrubbed and scrubbed back and forward and jumped around so you could hear the audio on scrub is correct but on playback it's incorrect. I then removed the audio from the layer and re-added and set to stream and it was fixed again. From then on I cut the video, I couldn't get it to screw up again.

     

    I definitely see the issue.

    Sounds about right, my work PC has Realtek onboard (SoundMax Integrated HD, Hardware ID:

    HDAUDIO\FUNC_01&VEN_11D4&DEV_194A&SUBSYS_10280293)

    and has this issue with CC. My home PC has onboard ASUSTek (VIA HD Audio, Hardware ID: HDAUDIO\FUNC_01&VEN_1106&DEV_0397&SUBSYS_1043836C) and works fine with as far as I can tell, though I've only used it sparingly at home.

    I'm getting exactly the same. Was fine in Flash CS6, but after getting Flash CC 64Bit, I can now no longer play the streamed audio at the right point in the editor. It's making animation/audio sync impossible. Luckily, I found that with Adobe Cloud, you can still download Flash CS6 as well as CC, so I just use CS6 for animation work now - not ideal, but at least I can get on with work. Adobe need to fix this in CC though!

    Someone this is important to should file a wishlist reportt. You can include this thread from several users about the same issue for plenty of evidence of the bug.

    Removing AS2 is a feature in my eyes . A reason to inform a client their 8 year old project actually needs to be updated..

    I think this is a serious bug. Stop.

    Adobe have to solve this!

    Flash is not a freeware tool and flash animation is the core of my business.

    No excuses!

    It is November 5th and the problem wasn't fixed. It is frustrating not being able to use CC because of this serious issue. Adobe, please fix it!

    Hi,

     

    While you're fixing this, please add the ability to export audio back into Flash CC.  Then I can use it.

     

    Thanks.

    I posted this answer in another similar topic, but it applies here as well-

     

    So, I've been dealing with this issue for far too long. I've researched and researched and it appeared that there really was no fix for this.

     

    Until now; possibly.

     

    We've tested this theory on multiple machines and it seems to have fixed our problem here at the office. Best of all, the fix was extremely easy.

     

    All we did was go to: C:\Program Files\Adobe\Adobe Flash CC

     

    Right-click Flash.exe

     

    Run as Administrator

     

    Done.

     

    Give it a shot; it appears to have fixed our issue. Hopefully it fixes your issues as well.

    Anyone figure this out yet?  Administrator seems to help but is certainly not fixing this.  This is driving me absolutely batty.  Such a big bug to persist this long in a software where this type of animation is daily ritual.

    I ran Flash.exe as adminisrator. To start with, I had the same problem as before, but after a few minutes it started to work! Now it plays at the frame I want it to.

    This bug still hasn't been fixed. I don't recommend Flash for any animator; the issue makes syncing to music and vocals extremely frustrating. This bug has been around for months without solution.

     

    • Running as administrator does not solve the problem.
    • You will have the audio bug even if you do not have a Beats Audio Soundcard.
    • The longer and more complicated your project, the more frequently the bug happens. When it first begins (around 15-30 seconds worth of frames and about 7 layers) you can make the audio stream as it should by clicking your audio track, setting it to "stop," saving your project, and setting the audio to "stream" again.
    • However, when you have about 60 seconds on your timeline, the bug happens a lot more, and you have to actually close the project to get the sound to work again if you do not have the patience to wait for it to fix itself. The wait ranges from 30 seconds to several minutes to never fixed until you close. It's highly unpredicatable. Sometimes it is not enough to close the project, in which case you must quit Flash and start it up again.
    • It happens with both mp3 and wav sounds.
    • After a month of this bug, I still can't pinpoint what causes it. It's completely random.
    • This post suggests it has something to do with scrubbing the timeline. I haven't been able to replicate the bug by doing this. It happens whether or not you use the slider or just click on frames to navigate.

     

    My system specs:

    Windows 7 Home Premium (Service Pack 1)

    64-bit operating system

    Processor: Intel i5-4670K CPU @3.40 GHz

    RAM: 8 GB

    NVIDIA GeForce GTX 660 Graphics Card

    Audio is also NVIDIA High Definition Audio

    The bug happens even if I plug in headphones to a regular audio port not on the graphics card.

    Other audio types I have are the Intel Display Audio and Realtek High Definition Audio. I've tried messing with audio settings to no avail.

    For what it's worth, Flash CS6 does not have this problem.  It has a different irritating problem that adobe can't be bothered fixing where the hotkeys stop working when you perform certain actions, but its not nearly as fatal as Flash CC's issues.

    Hello,

    Have the exact same problem, with flash cc... How is it possible to release such an expensive "professional" tool with that sort of a bug ?!

    It works normally in the older flash version (even cs6).

     

    Could you please clearly inform your customers about that feature : flash cc is not designed for animation, and it's impossible to manage sound correctly within the interface.

     

    To resume : sound set as "event" doesn't even play at all. Sounds set as "stream" always start at the beginning, whatever frame the cursor is...

    what a shame...

     

    Please could you inform us about a solution ?

    Thank you

    Hi All,

    While we agree that this a top most concern, unfortunately we do not have a consistent repro steps yet for this issue and that causes delay in our investigation. If you have a consistent repro steps and would like to spend some time with us, please let us know. We would be more than happy to hear from you.

     

    Thanks!
