If the speech is an mp3 file, try converting it to a wav file.
Is the track that the speech is on muted?
Have you tried increasing the volume level of that track?
Can you post a screenshot of your timeline?
I have played around with the mixer, nothing is on mute, volume levels are good, I have played with the levels.
I have watched videos with people having this problem in the pro version to see if I could get ideas, but of course those options are not available in this version, does noone else have this problem?
It's okay, I figured it all out, it seems like this program is touchy on audio codecs and doesn't like certain file types even though they are supported, all I did was simply convert my files; converting both video and audio parts of the file to something better and more "stable". My clips were in TS format and I wasn't too sure of the audio format of the file but this program doesn't like it.
Thanks for the interest anyways
