When you run aplay subsequently as below by changing the stream format: aplay -Dhw:2,0 -c2 -fS16_LE -r48000 /dev/zero -vv -d 5;aplay -Dhw:2,0 -c2 -fS24_LE -r48000 /dev/zero -vv as a single command, the format gets corrupted and audio does not play. So clear the ACP_(I2S/BT)TDM_ITER/IRER register when dma stops.
