Audio won't play on specific videos.

I work on Amazon's Mechanical Turk. I transcribe the audio for videos for a requester called Crowdsurf. I have never had any problem with any of the videos/audio for any of the tasks, but since purchasing my new laptop I have not been able to get the audio to play for certain videos. I'm on an N580. My speakers work just fine, I am able to play songs from iTunes, Youtube, and pretty much any other source. I have tried to play the Crowdsurf videos on another computer and the audio works just fine for the videos. As the audio is the key component to completing the work, I am not sure what to do. I'm not sure what information I need to provide for help but I can do so upon request. Any suggestions? Please help!

hi Vertigo406,
Welcome to Lenovo Community Forums!
It might be codec issues, Your system might not have the appropriate Audio and video codecs that the Video file Needs.
a simple Google search about Codecs can lead you to downloading Codec packs. Install it and you should be fine.
Hope this helps,

Audio won't play on tumblr videos or music posts; vines, and it will sometimes work on pandora, but most of the times not.

Like it says up there, videos will play but the audio will be silent. If I close and reopen firefox it'll work, but before I'm able to play videos; firefox will freeze and be unresponsive; and even then it only works for maybe a video or two before it stops working again. I recently had to reinstall flash and quicktime and all that because of the add-ons being vulnerable or whatever was going on with that; after I did that my problem started.

You should be able to re download
it iTunes store click on the Purchased link under Quick Links on the right. Navigate to the song you want and click on the cloud to re download.
Maybe delete 1 faulty song and try that first. Remember to empty the trash before downloading the new copy

Audio won't play on MPEG files from camera?

I'm having issues with my new video camera. I want to use my final cut express to edit the videos, but the audio on the video files won't play. The videos play just fine, just no sound. I've turned the volume all the way up on my mac, but still nothing.
Any suggestions to make the audio work?
(I'm not the most familiar with computers, so simple/specific instructions would be best)

You have to separate out the audio and video tracks (referred to as "demuxing") of an MPEG-1 or MPEG-2 file before you import it into FCE. Try MPEG StreamClip to convert the MPEG files into an editing format (DV Stream, for instance). If your camera outputs MPEG-2, you'll also need the MPEG-2 Playback Component.
Hope this helps.

Premiere Elements 4 audio won't play on mp4 files, codecs missing/unavailable on .mov files

I dowlnloaded Premiere Elements 4, and when I import mp4 files, the video plays but the audio will not. I've also tried to import .mov files, and an error message pops up that says "Codec missing or unavailable." I downloaded the latest version of Quicktime, but that didn't change anything. The files will play back on the video camera, but I"m having trouble with them on my computer. The audio on the mp4 files plays in Quicktime, but not the video, and vice versa when I import them into Elements. Any suggestions?

Does Quicktime Pro also edit .mov files on a PC?

Premiere Elements 4 pretty much works with tape-based digital video. That would be video from a miniDV or HDV tape-based camcorder. It doesn't handle other formats very well.
If you plan to edit MP4s, you definitely want to upgrade to a more current version of the program. If you can't install a current version of the program, you may need to address issues on your computer (such as an outdated operating system or underpowered hardware configuration).
Short of that, you could buy Quicktime Pro from Apple for $29. It will edit MP4s, even on a PC platform.

Help!! AVI audio won't play - Premiere Pro v.7

Hi!
I captured footage from my DV camera into Windows Movie Maker in the form of a DV-avi. (I use WMM because Premiere crashes when I try to capture DV video). And when I import the AVI into Premiere Pro v.7 the audio won't play in the project window. However, when I scrub the slider back and forth the audio does play (kind of).
I have never had this problem before. I've captured video many times and this never happened.
I tried re-capturing it 6 times, but still the audio doesn't play (except when I scrub).
Is there an option I clicked accidentally?
Any help would be really great.
Thanks a lot!

I think WMM creates type 1 files and Premiere needs type 2
You might Google for a converter
You might also use the free http://www.headbands.com/gspot to find out the file details, and report back so someone may be able to help
I installed that program. Very helpful and interesting. Thanks for the link.
I assumed, like you, that I had simply captured the AVI files as Type 1. But I guess they are Type 2, after all.
I don't know if this helps, but the AVIs play just fine in Quicktime, Windows Media Player, WMM and Winamp.

Quicktime 7.6.4 won't play h264 encoded videos on my 10.4.11 MacMini

Hello:
This is my first post. I read through the forums and this seems to be the correct place to pose my question. If it's not, my apologizes.
I'm trying to find out why Quicktime 7.6.4 won't play h264-encoded video on my MacMini (G4 PPC). I'm running 10.4.11. I recently installed Perian 1.2.1 and it got some .avi files to play correctly, whereas before there was no sound. But the h264 files still get me a black screen, albeit with sound now. Some h264 files can be played in VLC Media Player (but that's a horrible player compared to Quicktime in my opinion, as it constantly drops frames and eats 100% of my processor time), but VLC even has the black screen problem on some h264 files as well.
I've also tried MPlayer OSX but that's really an alpha-type development and has a lot of bugs. Many movies it can't even open.
Sorry for the rambling, but again my question: Is there any way to play h264-encoded video in Quicktime 7.6.4 on my Mac?
Thanks in advance for your expertise and advice.

Mr Ram,
There is a group of Quicktime specialists in Apple.com ⇒ Support ⇒ Discussions ⇒ Quicktime .
The more data you give us, the easier it is to help us help you to diagnose your problem. Your disk space would be very useful. Contrary to some, I advocate iDefrag to assist VLC and MPlayer, which you were a little hard on.
GNU/Linux's free offerings
MPlayer was developed a decade ago, and I prefer it for viewing DVDs (for 'DVD Player') seems too dark. VLC (legally) copies many CRM-protected DVDs of yours, so you can play only the burned copy. When I'm having a problem playing a DVD, the VLC log tells me all: only perfect DVDs play well on VLC.
There are two ways of viewing everything.
Streaming MPEG-4
+H.264/MPEG-4 AVC+ is a fancy codec based upon MPEG-4: it requires a powerful processor to de-compress it. I watched an MPEG-4 movie from a G3 iBook in 2005. It played flawlessly.
Your Problem
Quicktime 7.X applications can not play +H.264/MPEG-4 AVC+ streams. It was a bug Apple never fixed. Frames are dropped because H.264 is so slow that it requires special hardware. You, I'm sad to say, don't have it.
To quote the Wikipedia on Quicktime: 'QuickTime 7 lacks support for H.264's Sample Aspect Ratio .[67] QuickTime X does not have this limitation; many Apple products (such as iTunes and Apple TV) still use the older QuickTime 7 engine.'
My Quicktime Pro on a PPC PowerBook is 7.6.4. You can either use a Linux transplant or upgrade to Quicktime X. Those more familiar with Macs may have better ideas for you.
My best,
Bruce

Hype widget; audio won't play when previewing on iPad

Hi,
I've come across a strange 'bug' in iBooks Author. Hope someone can help.
I made a widget using Tumult's Hype software. It has multiple scenes, audio and animated text. When previewing the widget in Hype everything works fine. But here comes the strange part;
When I insert the hype widget in an empty iBooksAuthor book the animation and audio works fine when previewing on my iPad2. But when i insert the widget in my iBook, wich has already ten pages filled with text, reviews, etc., the animation work, but the audio won't play when previewing on my iPad.
People from Tumult helped me, but were not able to fix this.
So in an empty book the widget from Hype works fine, but when inserting the widget in a book that has some pages the audio won't play! How can i fix this?
Thanks for the support!

Spotify Desktop on Windows freezes consistently after playing a specific video ad

Hi, I'd like to report the following issue: DescriptionSpotify Desktop on Windows freezes consistently after playing a specific video ad (screenshot attached). This still happens after a reinstall. Please note that the UI is usable just fine. I can close the ad, browse playlists etc. but since the ad "haven't finished" it's not possible to play anything.This is happening on two devices (workstation and laptop), both running Windows 8.1. A more detailed description, using numbered steps1. Play any tracks2. Video ad comes in and plays without issues3. After 15 seconds it freezes and it's not possible to re-play4.

Audio won't play after replacing the video clip with after effects composition?

I am using CS5. Still new to this stuff so let me know if you need extra info. None of the faq guides have been helpful.

The audio is still in the project, but won't play in the canvas... this was solved by Richardttt... see this thread: http://discussions.apple.com/thread.jspa?threadID=1491870&tstart=0
I tried this and it works but still don't know why it happened: Under Object Menu, select Unsolo>Video Only.

Some flash video/audio won't play

Hello, I'm using 10.6.7 and the lastest Flash plugin.
I've troubles with playback some flash video and audio in all browsers: Safari, Firefox 4, Chrome.
For example, Soundcloud.com works fine, but as a widget on other web-sites it doesn't work. Youtube and Vimeo — perfect, but BBC's videos won't play (ex., http://www.bbc.co.uk/news/world-us-canada-13054205).
Any ideas?

Your link works fine for me in Safari.
Check your "extensions" (browser add ons) for your browsers. Some may conflict.

Audio won't play on slides containing Flash video

I've wasted pretty much a whole day on this issue, and it's
driving me crazy. I have a presentation that includes 2 flash
videos (screen demos). When I publish the presentation to our
company's web server, the audio for those 2 slides won't play, the
rest of the presentation works fine. If I publish to my hard drive,
the audio plays fine.

The audio for the FLV and the slide should be playing at the
same time (unless you put a delay on the video). To verify, in
Presenter, go to the slide that you are having issues with, select
Edit Video. At the bottom you should see the effects options. Tell
the video to start after the audio. Republish and see if your auido
is there, but was some how drowned out by the FLV. If that was the
case you may just need to boost the volume of your audio to be
louder than the video, but that may cause it to sound like noise.
As a final option, try putting the FLV on a slide following
the problem slide. This will disassociate any relationship between
the audio on your slide and the FLV,

Audio won't play on top of video

I have shot a simple interview style video and edited it in FCP. I created a simple acoustic guitar loop to play in the background using Garage Band and made it into an .aif format.
I've dropped the file into FCP, but for some reason the audio won't come out for the loop. I still have audio from the video, but the loop doesn't come through. When I watch the audio meter as the video is playing, I can see it responding during silence as if the loop actually is actually playing, but it's not coming out. (I've even listened with headphones to ensure this.) I have turned off the audio from the movie, played the video, and I still SEE the audio for the loop playing, but it isn't coming out of the speakers. I've tried renduring, and still the loop doesn't come through. I have ensured that my Audio rate from my file matches the audio rate from my sequence presets. I've tried changing my audio outputs from all stereo to all mono, to 2 stereo and 2 mono, and I still can't get the audio to for my loop.
Could someone help me out with this?

I know, it's shocking that no one has responded to this.
Anyway, No, I haven't created a new project, but it wouldn't matter because it would have the same settings as my original project. It's interesting to note that only the top two audio tracks will come through, and it's like anything below that will just simply not come out, even though the audio meter still registers the sound from the loop. (I've muted the sound from my video to ensure that it wasn't just background or room noise I was picking up.)
The track I created doesn't show a need to render, but you are correct in that I already checked this. I did, however, take another look at all of my audio clips and the sound of my video is apparently in a mono format as well as my sound loop. (Not sure HOW those became mono, but nothing a simple remixing won't fix.) Anyway, seeing that all of my sound files were mono, I went into my settings and changed all of my audio outputs to mono. So I even have 8 -That's right, count 'em... 8 - mono channels for sound and the loop STILL wouldn't come through.
I swear, sometimes this program makes me want to cus.

Video and audio won't play in Itunes...just a gray screen

i put my digital copy of the hangover on itunes but it won't play. it says it is playing but it's a gray screen and no audio. whats wrong??? it plays on my ipod touch fine though.

There is an issue with the latest iTunes version that is causing downloaded movies/songs from not playing on your computer, but should work on your iPod. Until Apple releases an update that'll fix this, this problem will probably not go away.

.mp4 video's audio won't play on Firefox, even with Microsoft Windows Media Player Firefox Plugin 1.0.0.8

Title says it all: trying to play any .mp4 video files, or anything that utilizes .mp4 files period, will have the video play just fine, but with absolutely no audio at all. I run a Windows 7 Home Premium, and have tested several sites that utilize .mp4 video files, and have tested it on Internet Explorer, with Explorer showing better results at playing both the audio and video.
I have checked to see if media.windows-media-foundation.enabled is true in the about:config menu, and restarted Firefox, but to no avail. Any ideas as to what could be the root of this problem?

Hi Soundless_Cyborg,
Can you please specify an example url where this is happening, sometimes the video player does not support the codec.
Maybe you need to set it as default for this file type:
Open Control Panel > Programs > Default Programs > Set your default programs > Select Windows Media Player from the lists under Programs > Set this program as default > OK
