Scratch

I have a game called supa slime adventure.
I am currently adding sounds.
i have Three sounds so far.
On the floor, jetpack and music.
On the floor squidge is working fine.

The jet pack sound is atually the car passing sound repeated without finishing.
It is fine until the sound ends when the rest of the sound plays. I have found the stop all sounds block, but as i said i have other sounds. Any idea's?

The music, is ok but you cannot hear the other sounds. I have found the sound volume block but that changes all the sound volume. Any idea's?
