Are you listening to the audio via headphones, the Mac's speakers or via something other method? Is this limited to your Mac only? What audio codec (window -> media information... -> codec details) is being used for the MKVs that have an issue?
Additionally, what VLC version, MacOS X version, Mac model?
Providing logs, messages, configuration info (VLC, OS, Hardware) and a clear explanation of the issue always helps the problem solvers help you, even if they don't end up solving the issue. Just think what you would need if you were solving someone else's problem. Additional: Always looking for eager and capable MacOS X developers to join the VLC team - for more information
