The free sound dilemma

Here I am to introduce you an interesting question made by Pierre Urban.

I think we all asked this question to ourselves, and did not answer for our convenience…

Here it is:

«I’m a french developer currently coding a game.
Your blog helped me a lot with some really specific stuff about AS!
Also about monetizing =)

I really appreciate your blog but I have a problem.
My game is almost finish and I have some difficulties to find some free sounds.
The fact is that I’ll add mochiAds ad system to my game and I would like to know how to get some fine sounds.
I found two websites: www.pdsounds.org and www.freesounds.org.
But I don’t know if I can use some sounds of these since the mochiAds will make me earn a little bit money… For freesounds, the CC licence is non-commercial use. Even if it was commercial use, I would have to add every owners of the sounds in the credit which will make a very long list. But usually I do not see a very long list of people in the credits of flash games, hence I thought there was another way to have sounds…

About the music: I found somebody who is OK to let me use a music he made on newgrounds.com.
I clearly told him I will put ads with mochiAds, but he responded that if it’s not commercial then it is OK… I guess he misunderstood the thing, no? Or maybe I misunderstood…
Does putting some ads on a flash games makes the thing commercial?

Maybe you can make a new post about how to find and use musics/sounds in a flash game which uses MochiAd?
Maybe about how to create our own music/sounds using some random software?
I’m almost sure that it will be really handy for many people! =)

I really must have miss something because I don’t get why I am getting so much trouble to put some random sounds (like gun reloading, explosions, etc.) in my game just because it uses mochiAds…»

If any music/effects composer is reading, I would like to know his answer.
