Maybe my question is stupid, I think the pipeline's start point is over here in dai_dma_cb() function:

 if (dev->state == COMP_STATE_ACTIVE) {

point */ pipeline_schedule_copy(dev->pipeline, 0); }

Where is the finish point of the pipeline? :-

Your pipeline is scheduled by the DMA callback and will run immediately atm.

Please look at pipeline_task() for start and finish trace messages.
