Hi friends , i want to use DirectSound for a project of mine and i want to mix few of the Wave files, there is one backgroud sound and rest are different small sounds, if i mix the sounds without streaming than there is no problem in mixing, as directsound is doing the mixing for me but when i use streaming as my background sound file is big than while mixing i dont get the desired result when the other sounds are also played simultaneously , the new sound is there but is suppresed and the background sound file misses out on some data ....these kind of irregularities i am facing, i think that the problem occurs while loading the buffer with the streaming data ,again and again.... So please tell me if it is possible to mix streaming sounds with ordinary sounds and how to do it using directSound , do i need to change the Primary buffer parameters...if yes than what , is there some sample available in net doing this ...
