VLC Media Player is a popular media player tool that supports a broad variety of file formats and codecs. The MP4A codec contains audio data and has been popularised by Apple, as it is used for iTunes song downloads.

File Won't Play

If the file refuses to play, it's possible that the required codecs are not installed on your system. Reinstall VLC Player, or install iTunes or QuickTime from the Apple website to resolve this. The file may have been incorrectly encoded or saved in the wrong format; try opening it in another media program to test this. Alternatively, there might be some Digital Rights Management, or DRM, built into the file that prevents it being played outside of an authorised application, such as iTunes.

Distorted Audio

If the audio is distorted or patchy, the problem could be the result of the way th file has been encoded or recorded. Again, test this in another program. There might also be an issue with your soundcard -- downloading the latest drivers via Windows Update is the most common fix for this.


Assuming the issue does lie with VLC Player and the specific file type M4A, you should update to the latest version of the software via the VideoLAN website and the latest codecs via the Apple website. If the file is protected with DRM, it will need to be converted into an open format before it can be played.
