From 46b60827568ca4aad15eeacbc9dcf8597986ca8e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 29 Apr 2015 18:01:58 +0200 Subject: [PATCH] aplay: Fix uninterruptible aplay When aplay is invoked to play from stdin, it can't be terminated by normal signals like SIGTERM or SIGINT. It's because our signal handler tries to trap as much as possible while the stalling point is not in the PCM loop but rather the file I/O. For fixing this, leave our signal handler once when a signal is received and snd_pcm_abort() is called. At the next hit, it shall be handled normally.
