添加到 /etc/modprobe.d/alsa-base.conf

Question

升级后我再也没有声音了

以下是我的系统的一些参数

uname -a Linux ap3 5.8.0-51-generic #57~20.04.1-Ubuntu SMP 星期五 4 月 16 日 12:34:52 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

lspci -v | grep 音频

00:1b.0 音频设备：Intel Corporation C600/X79 系列芯片组高保真音频控制器（修订版 06） 子系统：Dell C600/X79 系列芯片组高保真音频控制器 08:00.1 音频设备：NVIDIA Corporation GK107 HDMI 音频控制器（修订版 a1） 子系统：NVIDIA Corporation GK107 HDMI 音频控制器

aplay——列出设备

aplay：device_list：276：未找到声卡...

我关注了一些帖子，并尝试

添加到 /etc/modprobe.d/alsa-base.conf

选项 snd-hda-intel dmic_detect=0

并且还#添加到黑名单 snd_soc_skl /etc/modprobe.d/blacklist.conf

这一切都没有成功

当我启动音量控制时，我有一个虚拟输出，而不是通常的物理输出 - 扬声器或耳机

如果有人能帮助解决此问题，

HP Elitebook G6 遇到了完全相同的问题。我在 dmesg 中看到了以下内容：

这似乎对我有用：

sudo tee /etc/modprobe.d/alsa-fix.conf <<<'options snd-hda-intel dmic_detect=0'

和

sudo reboot

我可以在设置中看到我的声卡，而不再看到虚拟输出。
