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

- 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.
