sox分段错误

我尝试在 Raspberry PI 上使用 sox 录制声音失败：

pi@raspberrypi ~/tmp $ rec new.wav
Segmentation fault

玩也是如此：

pi@raspberrypi ~/tmp $ play test.wav
Segmentation fault

但它会为我转换文件：

pi@raspberrypi ~/tmp $ sox message.wav message.flac rate 16k
pi@raspberrypi /tmp $ mplayer message.flac
==========================================================================

调试信息似乎没有提供大量信息：

以下是一些可能有用的版本数据：

pi@raspberrypi ~/tmp $ sox --version
sox:      SoX v14.4.0

pi@raspberrypi ~/tmp $ cat ~/.asoundrc
pcm.!default {
    type asym
    playback.pcm {
        type plug
        slave.pcm "hw:2,0"
        }
    capture.pcm {
        type plug
        slave.pcm "hw:1,0"
        }
}

pi@raspberrypi ~/tmp $ uname -a
Linux raspberrypi 3.2.27+ #250 PREEMPT Thu Oct 18 19:03:02 BST 2012 armv6l GNU/Linux

这个 SoX 是基于 Debian 软件包的吗？因为问题看起来很像Debian 错误 #676167这是在版本 14.4.0-3 中引入并在 14.4.0-5 中修复的。

它还显示（从格式插件列表中）您没有libsox-fmt-alsa安装该软件包，但您需要它来进行 ALSA 播放。

因此，您应该安装软件包libsox-fmt-alsa并将其升级sox到至少 14.4.0-5，或者设置环境变量AUDIODRIVER=alsa作为解决方法。
