aplay -Dhw:0,0 -fS32_LE -c 2 -r 48000 -vv -i sine_48_2_32.wav - Stop and release playback pipeline several times by "space" key.
- Check rec.wav wave.

Does the wrong data fit well at the end of the previous stream?

@bkokoszx @slawblauciak @lgirdwood this also looks like an old issue without any update? isn't this fixed already?
