安装了 Ubuntu 20.04 的 Chromebook 没有声音。声音选项显示为“虚拟输出”

这似乎是一个非常常见的问题。我尝试了网上讨论的所有方法，但都没有奏效。

我有一台 HP Chromebook 13 G1，正在运行 Ubuntu 20.04，我的输出uname -srm是Linux 5.13.0-39-generic x86_64。

我使用 MrChromebox 在 Chromebook 上安装了 Ubuntu，我不确定这是否会有什么不同。我确信安装 ChromeOS 时声音最初是可以正常工作的。

以下是一些音频相关的输出：

$ lspci -nnk | grep -A2 Audio

00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d70] (rev 21)
    DeviceName: Multimedia audio controller
    Kernel driver in use: snd_soc_skl

$ aplay -l
aplay: device_list:276: no soundcards found...

$ pacmd list cars |egrep -i "output|active"

    argument: <sink_name=auto_null sink_properties='device.description="Dummy Output"'>
        device.description = "Dummy Output"
        device.description = "Monitor of Dummy Output"
0 source output(s) available.

$ lspci -v | grep -i audio
00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-LP HD Audio (rev 21)
    DeviceName: Multimedia audio controller

我已按照人们建议的步骤操作，但我不确定我是否正确执行了。例如，当人们建议添加options snd-hda-intel dmic_detect=0到时/etc/modprobe.d/alsa-base.conf，我应该用 替换，snd-hda-intel对snd_soc_skl吗？

如果有人能就此给我一些指导，那就太好了。

编辑：

我上面列出的输出适用于全新安装的 Ubuntu。在我更改/etc/modprobe.d/alsa-base.conf以添加以下行之后

options snd-hda-intel model=auto
options snd-hda-intel dmic_detect=0

我还补充blacklist snd_soc_skl道/etc/modprobe.d/blacklist.conf

现在我的输出是这样的：

$ lspci -nnk | grep -A2 Audio

00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d70] (rev 21)

显然这是一个已知问题，即现代 Chromebook（大约 2015 年）在安装其他版本的 Linux 时无法保持声音功能。

我知道的唯一例外是GalliumOS。需要安装哪个版本的 GalliumOS 取决于你的 Chromebook 型号，但我发现 Skylake 可以让声音与 HP Chromebook 13 G1 配合使用。

值得注意的是，蓝牙音频可以与其他 Linux 发行版兼容，因此根据您的情况，将 Ubuntu 与蓝牙扬声器或耳机一起使用可能会更合适。
