With Direct3D9 I did the type library and module support functions for DirectSound. The archive contains a type library dsvb.tlb and module DS_Functions.bas. In the future, I add a class module to support asynchronous notification until you can use clsTrickWait.cls. The module DS_Functions contains the following functions:
DSCreateSoundBufferFromFile - creates an object with interface IDirectSoundBuffer8 from a file. Supported only WAVE and MP3 files is. MP3 files can contain only the ID3v1 and ID3v2 tags, any other may not be recognized/will not work. Too long (by time) files are not supported. For streaming you need to write streaming decoding based on the function code DSCreateSoundBufferFromMemory;
DSCreateSoundBufferFromMemory - the same, but instead of the file is passed a pointer to the data file in memory and size.
Also in the archive contains an example of a player that implements some methods IDirectSoundBuffer8 interface (volume, pan, frequency, effects). TLB especially did not well tested, so something may not work. If something is not working please write here.
