![休眠后外部显示器声源无音频](https://linux22.com/image/954549/%E4%BC%91%E7%9C%A0%E5%90%8E%E5%A4%96%E9%83%A8%E6%98%BE%E7%A4%BA%E5%99%A8%E5%A3%B0%E6%BA%90%E6%97%A0%E9%9F%B3%E9%A2%91.png)
我有一台显示器,并通过 HDMI 将笔记本电脑连接到它。我已通过分区启用了休眠模式。每当系统在休眠后启动时,显示器的音频源都不起作用。如果我切换到笔记本电脑的音频,它就可以正常工作。每次我都必须重新启动才能启用外部显示器扬声器。我在另一个不同品牌的显示器上进行了测试,问题仍然存在。有时 Chrome 会出现视频播放错误。
以下是 DMESG 输出
