Stopping sound on other layers

Hello! I'm struggling with this issue as well. I want all layers to stay visible as learners click through each layer. But each layer on my slide has audio, and the audio tracks are playing over each other. I can stop the audio on the base layer, but the audio for the other layers plays simultaneously. Checking the "Hide other slide layers" box works to only play audio for one layer at a time, but then only one layer shows at a time. If Layer 1 opens and then users click on the trigger for Layer 2, I want only the Layer 2 audio playing while the contents of Layer 1 to stay visible.

I've tried creating layers with only sound in them and setting audio to play when the button state is "Selected" and nothing works. The twolayeraudio_mh.story file uploaded earlier in this thread seems to work, but I don't understand how to apply the settings to my own project. I cannot share my project due to client confidentiality, but any suggestions are appreciated.
