Quicktime won't play mp3

this is BEYOND annoying
I just upgraded to a brand new mac mini i7 that wont play mp3's or really another media in quicktime
i have an akai eie pro that may be effecting things, but still man c'mon. I'm tempted to just return this doorstop.
does anyone have any leads?

They just have the wrong creator.
Charlie Minow wrote a script to fix it and gives some background information:

I recently purchased QuickTime 7 Pro to convert avi files to mov files for editing on Imovie. However, QuickTime won't play the files. How can I get them to play and how can I convert them to mov files?

Both the AVI and the MOV file extensions refer to the file container and not the compressed data the file contains. Both are generic file containers in that each may contain any valid combination of audio and/or video data that is compatible with the codec component configuration of the system on which the file was created. On the other hand, whether a file is playback compatible, conversion compatible, and/or edit compatible depends on the data actually contained in the file container. So, you are basically dealing with two separate issues here—the container and what is inside it.
Basically, if you want to make your files ediit compatible with iMovie, you must change your file container to one that is acceptable to iMovie and convert the data to edit compatible audio and/or video compression formats as may be necessary. The best approach is to determine what codecs were actually used to create the original AVI files and add them to your system if possible. In most cases a codec package like Perian can be added to your system's codec component configuration to may the AVI file playable. Once they are playable, in the QT 7 app then they can be chnged or converted to file types and compression formats that can be edited in iMovie. (While Perian handles most codecs commonly used to create AVI files, it does not handle all possibilities and, while the Perian codec package still works under cureent Mac OS versions, its development group has decided to drop further development/support of the package.)
Background: AVI is a file container originally developed by Microsoft back in 1992 but for which official support was discontinued about 11 years. Despite its limitations, Windows users still tend to use this file based on its open source ease of use and generic nature, thus, making its use so popular that most users are unwilling to switch to more modern but less generic file types. Since some AVI legacy compression formats have never been transcoded for the Mac or use beyond OS 9 or OS X PPC platforms, it is often important to know what specific compression formats are contained in the AVI file to know which codecs to add to your system and which not to add in order to avoid possible codec conflicts.
You can use many different converters to convert AVI files to iMovie edit compatible files. Most third-party apps contain their own buit-in codecs which do not relay on the Mac codec component configuration. Free ones, like HandBrake, usually have limited conversion capabilities while those that have more varied outputs are usually commercial in nature and will cost you additional cash. QT 7 Pro or the free MPEG Streamclip app allow you to access you own system's component configuration and use any available codec component like DV, AIC, MPEG-4, H.264, Photo JPEG, etc.—all of which are iMovie compatible for editing purposes—but only after making the AVI file QT 7 player compatible.
In order to determine what compression formats wewre used in your AVI files you can
1) Try checking the Finder "Info" window,
2) Use the "Inspector", "Media Info", or "Properties" window of any player app that will open the file, or
3) Use a general media utility app like "MediaInfo" to read the file characteristics.

How do i change my quicktime player default back to quicktime 7 as my new quicktime won't play certain formats

how do i change my quicktime player default back to quicktime 7 as my new quicktime won't play certain formats

Select one of those files, CMD+I, select QT 7 from the Open With list, and then click the Change All button. Repeat for any in the format class you want to change.

Quicktime won't play my .mov files since I upgraded to Mavericks.

Quicktime won't play my .mov files, even those from an iPhone, since I installed Mavericks. "Tell Me More" doesn't tell me anything about a solution. Any suggestions?

What do I do?
Frankly, if you have deleted the original movie clips from your camera/camcorder and iPhoto, then it sounds as if you are up the proverbial creek without a paddle and there is nothing further that you can do.
Some facts:
For some reason, the movieclips are awful small (13-30 KB).
640 x 480
Codecs: H.264, AAC
While these facts are of little value without file duration information, as you yourself have already noted, the file sizes quoted are extremely small. A typical VGA H.264/AAC file of reasonable quality would normally have a combined total data rate in the 700 to 1,700 Kbps range depending on specific settings, profile, and level of the encoding software and could be even higher or lower depending on the quality levels required. Therefore, it is reasonable to assume that files in the 13 to 30 KB range only contain 104 to 240 Kbs and either have durations measured in fractions of seconds or do not actually contain enough data to be played. (E.g., the video data may be missing or the file is corrupted.) Thus, it is most likely that something was wrong with the workflow used to "export" your files to the external drive and when you ignored the fact that the files were not playing correctly, you closed the door on anything that you could do when you deleted the source files. (I.e., the normal workflow here is to copy the entire iPhoto library to the external drive, switch libraries, confirm the new library is working properly and only then delete the boot drive copy of the iPhoto library.)
OBS: When I try to convert the files into something else (AVI, MP4 whatever) either it comes with an error, nothing happens or the converted file wont open. This happens with various convert-programs.
If the data in the files is missing, then there is nothing to be converted by any application.

Banshee won't play MP3s [SOLVED]

Hi everyone,
Banshee won't play MP3s which are playable in
VLC, Amarok and the Firefox and Chomium when opened directly.
When i attempt to play an MP3 it skips next track until it reaches the bottom of the list.
I would love to simply use Banshee since it can download the content from the Amazon Cloud.
Thanks in advance for any help

Banshee won't play Mp3's

Hi everyone,
Banshee won't play MP3s which are playable in
Clementine, Audacious.
When i attempt to play an MP3 it plays as if it is muted. I have checked that the sound is turned up and is not muted.
my sound works fine so it can't be muted.
I have confirmed that the codecs are installed....gstreamer0.10-plugins

Banshee switched to gstreamer 1 and the output (the last message actually from banshee and not some generic glib error message) confirms this. Therefore the obvious question would be, have you also made sure to have the gst plugins? (gst-plugins-ugly for MP3 to be precise)

N95 won't play mp3

My N95 (Vodafone) won't play .mp3 files. I copied a gigabyte of tracks to my 2Gb memory card. The music player sees all the tracks fine but when I try to play one I get about a second of music & then silence. It appears to play (time counter moves forward) for about 20 seconds & then stops.
I tried copying a track to phone memory in case it was the card but the result was the same. These tracks play fine on my iPod & on my pc.
A .dcf file in my Digital Sounds folder plays fine.
Do I just have a broken phone that I have to send back?

scoobyman,
thanks. I had a look at that but my problem is not with transferring mp3 files. I copy them directly to the memory card. The problem is that the N95 will not PLAY them.

Safari won't play mp3 - only downloads the files

Very annoying, this: I am running Safari 5.1.4 on a Lion MacBook Pro (latest version of Lion), but for some reason it won't play mp3 files - it always ends up downloading them.
However, if I try the same web page with the same mp3 files on, say, Chrome, they play just fine.
How can I fix this?

Thanks for the reply, but that's not what I want at all - it's too inconvenient.
I want mp3 files etc. to play back from *within* Safari, like it used to. Not sure when this was broken, but it is broken. As I said in the first message, playing mp3s etc. from within Chrome works just fine (I don't have to open another app to play them back), so I know this should work in Safari, too.

ITunes 11.0.3 won't play mp3 I download online

I have itunes 11.0.3-when I download mp3 songs, it will not open up in itunes and play, which is my default music player. What is going on? I've googled this issue and nothing has come up. I've tried every solution I can possibly think of. All it does is open up iTunes, but it won't play or even save. What do I do?!?! I only use iTunes and sync everything with it. This is super frustrating!

Anfarr,
First of all, make sure that it downloads and saves to your computer. That is the job of the browser, not of iTunes.
After it saves, make sure it is a valid MP3 song file, since many downloads from the web are not valid. Did it play correctly in another player, such as Windows Media Player or Winamp?

.MOD files in Quicktime won't play

I'm trying to convert .mod files into MPEG files. I'm working on an
iMac 3.06 GHz Inteal Core Duo. I shot video on Canon FS100 camera and
when I uploaded the video and the files are ".MOD"s. I can't play them
on my computer. I changed the file extension to .MPG. but it won't
play on my quicktime (Version 7.5.5 (249.24). How can I get these to
play?

Checking the forums, I found threads that point to using Streamclip. I tried it and got this message:
"You will miss the two most important features of MPEG Streamclip:
- you won't be able to play MPEG-2 files and transport streams;
- you won't be able to convert MPEG-2 files and transport streams to QuickTime, DV, AVI.
However, all other features are always available, including playback and conversion of MPEG-1 to QuickTime, DV, AVI, demuxing of MPEG-1 and MPEG-2, AC3 decoding, and conversion from transport streams to MPEG files (useful if you have Toast 6).
MPEG Streamclip is free of charge but the MPEG-2 Playback Component has a small price (around $20/£15/€20 in most countries); you can buy it online from Apple:
http://www.apple.com/quicktime/mpeg2"
Is this really the only way?

QUICKTIME WON'T PLAY MOVIES???

Does anyone else have the problem with Quicktime 7.4.5 not playing any type of movies (mov/mp4/avi)? Until the latest update for itunes/quicktime I had no problem playing the movies. Now I keep getting "Error -50: An unknown error occurred (name of movie.extension)". Most of my movies were converted from .flv to .mp4 then saved with quicktime to .mov. I used "Replay Converter". Again until today, quicktime had NO problem playing any of these files...now it can't play any of them.
Any suggestions?

For a long time, there was a bug in the conversion of .flv's to .mp4 in the ffmpeg libraries. This caused any app that used ffmpeg to create non-standard .mp4 files. This bug has now been fixed and everything should work as normal. However, those older files that were not created according to the .mp4 standard won't play when they have an .mp4 extension.
On the Mac side, an app to fix these have been released, I don't know about the PC side. Others have noticed that if they change the extension to .3gp, they will play (and they're reported to play in iTunes as well).

Quicktime won't play videos online. ???

I just downloaded quicktime, and then restarted my computer. But it still won't play videos online. I'm not sure if it is like this for all sites, but i have one site in particular that won't play videos. Any ideas? I have Windows 7 by the way.

I come across this a lot, actually. I'm tired of having to switch to Firefox in order to view certain quicktimes. Here's a clip that won't play for me:
http://www.chartoonz.com/index.html
I can't figure it out because Safari will play quicktimes, even other h264 quicktimes, but then I'll run across an h264 on someone's site and I get the question mark.

Quicktime won't play in Mozilla Firefox

Hi,
I recently installed a newer version of Quicktime, 7 I think, and now Quicktime items won't play in my Firefox. They did before I installed the new version, and things load just fine in Internet Explorer, but I really would like it to also work in Firefox.
I've fiddled with different settings in the Quicktime and my Internet Options, but nothing seems to work. I am by no means good at that sort of thing, so I hope I didn't mess anything up further.
Any ideas how to get it to work again?
Thanks so much!

The settings on firefox were fine. It turns out that I had to change my code from object top embed. That worked and got the video to play in firefox. But ironically now the sound only sometimes works in firefox. If it is not one problem it is another. lol If you have any insight you can share it would be greatly appreciated.
Thanks man.

Are there iTunes Preferences that first need to be in place before playing an MP3 created in iTunes and received through the Internet?
I've created a song in GarageBand2 then exported it to iTunes, and finally converted it as an MP3 to email through the Internet.
Various friends tell me the song plays fine on PCs without iTunes, yet, one friend who is using an iMac/iTunes setup cannot play it! How can this be?
Any help would certainly be appreciated.

Choose a genre you like and download
any one file for testing. All the files on
Download.com are in the mp3 format. See if iTunes
will play that file.
Let me know if you can play the mp3 file you
downloaded. If you can, then the problem is not
iTunes ability to play mp3 files but with the discs
themselves.
Tom -
I did what you suggested and had no trouble with iTunes playing the mp3 file.
Because you cannot see the discs in Finder and need
to shut down the computer to eject the discs, I
suspect there is a problem with the discs themselves.
Couldn't the problem still be with the iBook? The reason I say this is because I was able to play one of the disks before on the iBook. Now it won't play.
On the other hand, all these disks come from the same source and may be defective in some way as you suggest.
Have you tried playing the discs in another computer
or mp3-enabled cd player?
As I don't have another mp3 player, I'll have to find someone who can test them and let you know. I won't bother you again until I find out.

QuickTIme won't play movie only on just one page!

Good morning all, My Brother has a iWeb site where he shares with me videos of my nephew's on only on just one page the quicktime logo with a question mark shows up and won't play, yet the same page will play on my iPhone. Could anyone guide me through I might be able to fix it? I really want this page to load so I can save the video of my nephew. I've reset the cache, reset safari, repaired permissions. Not sure what to do. I'm nervous about reinstalling quicktime from the Apple site because it doesn't say anything about Quicktime X, also I tried opening the URL in Quicktime Pro, but that didn't work either. It's just this one page that won't load right! Thanks so much for your help!

What is so frustrating to me is I am trying to view a website made and with iWeb09 and the videos in the site hosted by MobileMe are shot with an iPhone3GS! I just can't figure out why the only video's that won't play are from my brothers website. He has tried visiting his own site and they play fine, and it plays fine on my iPhone! Is there some setting somewhere I am missing?
Based on the fact that content plays on your brother's computer, as well as, your iPhone, the most likely source of the problem would be your platform configuration. While I can understand it may not be desireable for the general public to have access to your family's personal web site, knowing the specific compression formats and actual settings used in the uploads is often key to deteriming the specific problem and solution here. And, while the list of players and components provided by Baby Boomer normally handles 96-98% of the content you are likely to encouter, it does not help to identify your individual problem.
Basically it would appear that some component or plug-in on your computer is not functioning or installed properly. Many users who have upgraded to Snow Leopard have reported that some add-on codecs (e.g., the QT MPEG-2 Playback Componet, Perian, etc.) are not properly re-linked to the new OS and have to be re-installed. In a similar manner, if there was a problem during the Snow Leopard installation, the regular system components could be missing or corrupted. By knowing the specific compression formats involved, it might be possible check to ensure that they are/were installed in their proper location and/or test their current servicability within your system. In addition, you may want to download the source files to see if the play correctly locally to determine if the problem is in the codec, your browser, a plug-in that may be needed to support the browser, or some sort of conflict (e.g., common component conflict as described on the Perian site).
