Field Documentation

◆ audio_set_ipc_params

int(* audio_buffer_ops::audio_set_ipc_params) (struct sof_audio_buffer *buffer, struct sof_ipc_stream_params *params, bool force_update)

OPTIONAL see sink_set_params comments.

◆ free

void(* audio_buffer_ops::free) (struct sof_audio_buffer *buffer)

this method must free all structures allocated by buffer implementation and the buffer itself OBLIGATORY

◆ on_audio_format_set

int(* audio_buffer_ops::on_audio_format_set) (struct sof_audio_buffer *buffer)

OPTIONAL: Notification to the sink implementation about changes in audio format.

Once any of *audio_stream_params elements changes, the implementation of sink may need to perform some extra operations. This callback will be called immediately after any change

Return values

0	if success, negative if new parameters are not supported

◆ reset

void(* audio_buffer_ops::reset) (struct sof_audio_buffer *buffer)

clean all buffer data, set buffer positions to initial, leaving config as is the procedure is to be called only when buffer is not in use OPTIONAL

◆ set_alignment_constants

int(* audio_buffer_ops::set_alignment_constants) (struct sof_audio_buffer *buffer, const uint32_t byte_align, const uint32_t frame_align_req)

OPTIONAL see comment for sink_set_alignment_constants.
