For wake on voice use case, we need to copy data from DSP buffer to PCM stream when system wakes up by voice. However the edge triggered IRQ could be missed when system wakes up, in that case the irq function will not be called. If the substream was constructed beforce suspend, we will schedule data copy in resume function.
