Sound not working

Hi all,

I’m running Audacity 2.0.6 on OS X Mavericks. I have made a screen cast but the volume changes drastically in the .mov file so apparently I need to compress the audio. I’ve imported the .mov file but when I select a section of the sound and then press play I get no sound. I’ve looked through plenty of FAQs and tutorials but cant seem to find a solution, what am I doing wrong?

This is the first time I’ve ever used a program such as audacity or tried editing sound.

Cheers

Okay I think I’ve figured it out, I was trying to change the output while the track was playing, I’ve just dicovered that if I pause I am able to change the output…
Doh! :unamused:

Anyway hope I havent wasted anyones time, Thanks!
