Bug Description
Project partner pointed out the following:
Playback works as expected for the Presets, like Cascade Creek. But trying a different sensor setup on Wisp: When I hit play, the track does not play. If I make a second track, and hit play, then the second track will play but the first track still does not and the red scroll bar moves across for the second track but not the first. The sounds and selected sensor do not autoupdate when selected while play is enabled (but for the preset datasets it does autoupdate). I have to hit stop, then play again for changes in selections to take effect.
I seem to get the bug (the track not playing while the others do) on battery voltage when it is selected in the track. Not so much with the others. So maybe this is a good place to look for the solution!
