症状
我听不到声音。
在设置应用程序的“声音”选项卡中，我可以选择以下设备：
HDMI/显示端口 - 内置音频
数字输出 (S/PDIF) - 内置音频
耳机 - 内置音频
虚拟输出
当我点击任何一个扬声器上的“测试”时，没有可以点击的扬声器。我期望会显示“左”和“右”按钮。
更新 1
当我从命令行以详细模式启动 pulseaudio 时，它会在几秒钟后快速终止，并显示：
I: [pulseaudio] core.c: We are idle, quitting...
I: [pulseaudio] main.c: Daemon shutdown initiated.
以较大的空闲超时启动 pulseaudio，给出相同的结果：没有音频输出，对话框中没有扬声器。
更新2
当此问题发生时，重新启动可以暂时解决问题。
我尝试在重启后通过挂起/唤醒循环触发此问题，但唤醒后声音仍然正常。因此，需要不止一次挂起才能触发此问题。
