mkv shrinks but no audio

[mysts]

I just used handbrake to shrink a mkv file. The process went just fine except there is no audio. How do I get the audio back?

Authoring? Nope. Conversion. Moving you.

WHat is the audio source in the mkv?
To what format are you converting the audio to?
Tried used copy/passthrough?

The specs on this file are as below. I would like to keep the audio if possible. How do I tell handbrake to do this.

Check under the audio tab and change the audio codec setting to pass-through.

Or shrink your mkv using uncropmkv. It wont touch the audio.
