在装有 Ubuntu 19.04(与 Windows 10 双启动)的 HP 笔记本电脑上,内置扬声器和耳机可以正常工作。不幸的是,只有在启动或重启后才能正常工作,在将笔记本电脑从挂起状态唤醒后则无法正常工作。
Ubuntu 在挂起后识别音频设备(在 lspci 中列出),但扬声器和耳机均无法工作。音量可以修改,但不会改变任何内容。您知道如何在挂起后强制重新加载它们吗?
sudo lspci -v

重新启动和从挂起状态唤醒后立即给出相同的输出:

我尝试了建议的命令在步骤 1 下没有成功。
我的笔记本电脑是 14ma0307ng。

看起来像这个错误:https://bugs.freedesktop.org/show_bug.cgi?id=110916#c5
在补丁进入 Canonical 的存储库之前,还有一个解决方法。如果你不需要 HDMI 音频输出,只需删除
snd_hda_intel.probe_mask=0x01
到内核启动参数。对我有用。
