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

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 } --- aplay/aplay.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
