The MKV codec pack can handle video playback error on Mac and Windows. But codec pack usually comes with a bunch of stuff that you don't really need rather than the MKV only, making it heavyweight and CPU consumption. Worse still, codecs are notorious for bundling crapware or even malware that leads to instability of your computer. You are missing an audio codec or the audio is a format that is not supported. To check which audio codec your file is encoded with, see No audio or audio is distorted with DivX movie playback on a Mac for reference. Note: If your file is encoded with MPEG2 or AC3.
This appendix describes the audio data and file formats supported in Core Audio in OS X v10.5.

Each audio file type lists the data formats supported for that type. That is, a converter exists to convert data from the particular file format to any of the listed data formats. Some data formats (such as AC3) cannot be converted to a linear PCM format and therefore cannot be handled by standard audio units.
A Core Audio Format (CAF) file can contain audio data of any format. Any application that supports the CAF file format can write audio data to the file or extract the data it contains. However, the ability to encode or decode the audio data contained within it is dependent on the audio codecs available on the system.
