Why can't I get audio on my video that I uploaded to youtube?

[Tarser]

I uploaded two videos to youtube without a problem. On the third one, there was no sound. I tried again...and again..and again.....then gave up....I tried the 'help' section on youtube - incomprehensible! I've got people on youtube asking me to make more videos. I'm really frustrated by this. Is it my camera? Is it my computer? Can someone help without technical jargon that I don't understand....Cheers!

Did you own the music? have YouTube muted it because of copyright?

What are you making the video with? What codecs are you using?

Are you sure that there's not a notice on the Youtube page, advising viewers that the audio has been removed because it's unlicensed? That's the most common reason for audio to disappear from Youtube videos.
