ok, this is odd but i narrowed down the issue to this situation:
sound object A linked to an ogg file, gain 0.6, speed 1, no loop
sound object B linked to the same file, gain 0.6, speed 3, no loop
the second object is used only in a particular game mode and if i activate that mode, after several sound plays, i get the sound buffer full error
if i don’t play that sound object, i don’t have the error
i’ll continue to investigate but this are the evidences right now and i’m puzzled
edit: if i set object B speed to 1, no error
