Return Values
Errors are represented by negative values and cannot be combined. This table lists the values that can be returned by all IDirectSound and IDirectSoundBuffer methods. For a list of the error codes each method can return, see the individual method descriptions.
| DS_OK | The request completed successfully. |
| DSERR_ALLOCATED | The request failed because resources, such as a priority level, were already in use by another caller. |
| DSERR_ALREADYINITIALIZED | The object is already initialized. |
| DSERR_BADFORMAT | The specified wave format is not supported. |
| DSERR_BUFFERLOST | The buffer memory has been lost and must be restored. |
| DSERR_CONTROLUNAVAIL | The buffer control (volume, pan, and so on) requested by the caller is not available. |
| DSERR_GENERIC | An undetermined error occurred inside the DirectSound subsystem. |
| DSERR_INVALIDCALL | This function is not valid for the current state of this object. |
| DSERR_INVALIDPARAM | An invalid parameter was passed to the returning function. |
| DSERR_NOAGGREGATION | The object does not support aggregation. |
| DSERR_NODRIVER | No sound driver is available for use. |
| DSERR_NOINTERFACE | The requested COM interface is not available. |
| DSERR_OTHERAPPHASPRIO | Another application has a higher priority level, preventing this call from succeeding |
| DSERR_OUTOFMEMORY | The DirectSound subsystem could not allocate sufficient memory to complete the caller's request. |
| DSERR_PRIOLEVELNEEDED | The caller does not have the priority level required for the function to succeed. |
| DSERR_UNINITIALIZED | The IDirectSound::Initialize method has not been called or has not been called successfully before other methods were called. |
| DSERR_UNSUPPORTED | The function called is not supported at this time. |
