Forget it. I figured out a work around for the sound effects problem. Tag every sound effect that lasts a whole panel "ambient" and set it to "looping". In my pause HUD, I tell audio to mute "ambient" when paused and unmute "ambient when unpaused. This works just fine. The only problem I still have for sfx is when it is a non-looping sound, but that doesn't happen as often.
For the music playback problem when going between my title screen and the first layout, it seems to be limited to only Chrome. Playback of Layout 1 starts when it should with all other browsers. However, not every browser pauses and unpauses the music correctly. I think this is a browser problem, not a Construct 2 problem.
So there it is. Maybe once I get comfortable with the audio plugin more I'll do a tutorial since this is a common problem people are having and there is no tutorial or info in the manual on how to resolve it.
