- * TODO(crbug.com/972928): convert this from unified_cb.
- * Args:
- *    client - The client to add the stream to (from cras_client_create).
- *    direction - playback(CRAS_STREAM_OUTPUT) or capture(CRAS_STREAM_INPUT) or
- *        loopback(CRAS_STREAM_POST_MIX_PRE_DSP).
- *    user_data - Pointer that will be passed to the callback.
- *    unified_cb - Called to request audio data or to notify the client when
- *                 captured audio is available. Though this is a unified_cb,
- *                 only one direction will be used for a stream, depending
- *                 on the 'direction' parameter.
- *    err_cb - Called when there is an error with the stream.
- *    format - The type of the samples, ex. S16_LE.
- *    frame_rate - Sample rate.
- *    num_channels - Number of channels in the stream, should be 1 or 2 when
- *        using this API, for > 2 channel streams see cras_client.h.
- *    dev_idx - Set this to a negative number to play to the default device, if
- *        positive it is the index of the device to pin the stream to.
- *    stream_id_out - On success will be filled with the new stream id.
- *        Guaranteed to be set before any callbacks are made.
- * Returns:
- *    0 on success, negative error code on failure (from errno.h).
