I have imported many sounds to my game, and in my case the only thing that causes this problem u encountered.
Is that i needed to setup the correct format within a sound editor.
Now i have downloaded samples from the internet that did have these specs.
But when they did not work in construct 2 i only needed to open them in my sound editor, and then re-export the wav to 44.1 hrz & 16 bits.
My gues is that not all wav "sound" files are build correctly.
So in my case its not really a construct2 problem.
Its just faulty music files.
Resampling works everytime and the m4a does work as it is a fundamental extension for some browsers.
