| Information | GetCaps |
| GetFormat | |
| GetStatus | |
| SetFormat | |
| Memory management | Initialize |
| Restore | |
| Play management | GetCurrentPosition |
| Lock | |

| Sound management | GetFrequency |
| GetPan | |
| GetVolume | |
| SetFrequency | |

All COM interfaces inherit the IUnknowninterface methods. This interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPDIRECTSOUNDBUFFERtype is defined as a pointer to the IDirectSoundBufferinterface:
typedef struct IDirectSoundBuffer *LPDIRECTSOUNDBUFFER;
