[alsa-devel] [PATCH 2/2] aplay: Escape from pcm_write() when in_aborting state

[Sergey]

This patch fixes aplay freezing and not responding to Ctrl+C
when playback pcm is stuck and returns 0 to write attempts:
Example:
  # aplay -vvv /dev/zero
  pcm.!default {
    type plug
    slave.pcm { type null }
    slave.format S32_LE
  }
