The "currentTime" property stays at 0 for a brief period in the webkit implementation. This is most prominent on iOS6 where it can take up to 6 seconds for currentTime to begin updating. The way I work around this is to wait using setTimeout until currentTime becomes > 0 before doing anything else. On PCs, this time is negligible in most cases, but shows up as multiple sounds getting triggered simultaneously on the rare occasion if the page starts playing sounds at or close to load time (it is difficult to get a reproducible case). 

I've just filed this - https://code.google.com/p/chromium/issues/detail?id=159359
