Help with pencil? (#2)

Disregard my other post sorry guys :)

I have pencil V0.5 beta and everything works fine :D But when i put the audio in and push play no sound appears

I am unable to download the other version for mac because they dont work for me, and only beta works for my computer.

SO my question is:

Is there a way to fix this?

I already downloaded a windows version with my mac using wine and the audio feature worked. Im confused can someone shed some light on my question.
