How are you measuring latency?
I don't think there's anything we can do anyway, since the delay must be in Chrome or possibly the Android OS. There is no delay on C2's side, it says to play audio right away, and it does play right away on all other platforms.
Ashley , i'm recording the device(see the video in the first post), and each frame of delay between the collision/sprite turns visible and the sound, represents 33ms if the video is 30 FPS(1/30*1000), but i shot the videos at 60FPS for more accuracy.
It seems that is a Chome problem(crosswalk does the same), but it's weird that very few people noticed this.
