Pause and Stop sound don't work...or?

Hi Henrik, welcome to the community, rather than fiddling around with triggers, it may be easier to put  the audio files on layers and then show these layers as the various hotspots are clicked. This way, the sound from one layer is automatically stopped when another layer is called. Also, the baselayer audio can be paused when a layer is displayed. Here is an example of a slide with audio on the baselayer and audio on various layers. Hope that helps.
