在过去的几天里，我养成了让 alsaplayer 循环播放的习惯。一旦结冰，它就停止了；醒来后，它又恢复了……好几次。上次没恢复。 dmesg 显示 snd_hda_intel 连续页面错误。杀死 alsaplayer 没有帮助。新的 alsaplayer 实例无法启动，被阻止等待来自我的/tmp/alsaplayer_ale套接字的第一个响应。我无法删除内核模块。不得不重新启动。
我没有脉冲音频。
为了冻结，我先运行xscreensaver-command -lock，然后pm-hibernate。我学会了在冻结之前释放 dhcpclient 租约，在/etc/pm/sleep.d.我想我应该做一些类似的事情来刷新音频通道，但不知道如何实现这一点。有什么提示吗？
编辑 我添加了一些日志，尽管目的不是调试内核，而是确定一个干净地停止播放的过程。声音缓冲区也应该被刷新，以便在远程流的情况下获得更干净的终止和恢复。
