Yep. Sound playing in pygame is crappy. I tried to use it, but cpu consumption is just enormous for that little thing. You can just use Code: hildon.hildon_play_system_sound(absolute_path_to_the_sound_file) I'm not sure if it can play files other than WAV (no time and too lazy). The other way, if you need to play other formats, could be using OSD, MPlayer, other player, but it seems to be a bit heavy.
