While playing a game under construction in the editor I have two issues with sound.
1. The first time playing a background-sound the sound quality is terrible. Loud, sounds like it playing over itself. Once the first sound file has played through, the rest of the sounds plays normal.
To me this only happens in the editor. Playing a built version in browser or as desktop version don't have the problem, for me.
I now have had a complaint from a user ('the music overlaps itself') that indicates that the problem may appear in a browser played version as well. [Possibly also a second complaint, but that one is a bit more vague and could be a dislike of the music as such. ]
I suspect this could be a browser (and possibly OS) related problem.
Is this a known problem? If it is, it could be nice to at least be able to give a warning to potential players when posting the game.
2. Video-clips with soundtrack will not play the sound in the editor, but will play sound in built version in browser and desk top. No indication of problem from other players, but that is also something that is less likely to generate a complaint.
I'm using mp4 files. Also have tested ogv and mkv, but I suspect mp4 can be played in more different browser types.
