ASoC: SOF: pcm: harden PCM STOP sequence The old STOP sequence is: 1. stop DMA 2. send STOP ipc If delay happen before the steps 1 and 2, the DMA buffer will be empty in short time and cause pipeline xrun then stop the pipeline. Then the step 2 ipc stop will return error as pipeline is already stopped. Suggested change to avoid the issue is to switch the order of steps 1 and 2 for the stop sequence.
