I can't understand much of what you're saying, but just looking at your code you are using the stop function incorrectly.

The stop function is supposed to receive a stream id, not a sound id.

A stream id is the value returned from the play function, and identifies a particular instance of a playing track.
A sound id is the value returned from a load function, and identifies a loaded resource.
