As mentioned by a few others, there seems to be an issue with music consistently playing in the Edge web browser (Note: I am running Windows 10 Pro x64 with the November Threshold 2 update). The Space Blaster demo was mentioned in another thread, so I used it for my testing (see below for how to replicate the problem).

Steps to Reproduce Bug
This bug seems to be intermittent, so the easiest way that I found to replicate it is to start Construct 2 and run the Space Blaster demo. If the music plays, then press "F5" (which will reload the game). I have found that after a few times of pressing "F5" the game will start with the music not playing.
The music will intermittently play. As an additional observation, I have noticed that if you move the music files to the sound folder, then the problem seems to go away.
