Ubuntu 20.04 上没有声音（Dell XPS 7390 / Realtek ALC3271 / Intel Corporation Device 02c8）

772

我这个周末在我的戴尔 XPS 7390 上安装了 Ubuntu 20.04，但似乎无法让声卡工作，根据 BIOS，它带有 Realtek ALC3271 控制器。pavucontrol除了虚拟输出之外，不显示任何接收器或源。以下是我已经尝试过并且到目前为止能够找到的内容：

$ pacmd list-cards
0 card(s) available.

$ aplay -l

（这里没有内部声卡的迹象。）

输出hwinfo：

的音频相关输出lspci：

$ sudo lspci -v

        Kernel modules: snd_hda_intel, snd_sof_pci

奇怪的是，当我写这篇文章时，输出$ sudo lspci -v正在改变。当我在一分钟前再次执行它时，与音频相关的输出突然变成了

$ sudo lspci -v

...skipping...
        Kernel driver in use: sof-audio-pci
        Kernel modules: snd_hda_intel, snd_sof_pci

并且从上方看不到 02c8 设备的迹象。但截至目前，它又回到了“正常”状态（即之前的输出，见上文）。

同时，输出dmesg根本没有改变，据我所知，它报告一切都很好：

到目前为止我已经尝试过：

添加options snd-hda-intel model=generic到/etc/modprobe.d/alsa-base.conf
添加options snd-hda-intel model=auto到/etc/modprobe.d/alsa-base.conf
在 BIOS 中禁用声卡，启动 Ubuntu，重新启动并再次在 BIOS 中启用声卡，再次启动 Ubuntu（如此处推荐）

可能相关（或类似）的问题：

通过添加. snd_hda_intel.dmic_detect=0_GRUB_CMDLINE_LINUX_DEFAULT/etc/default/grub

示例条目/etc/default/grub：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep snd_hda_intel.dmic_detect=0"

编辑文件后，只需运行sudo update-grub并重新启动。

注意：只有snd_hda_intel.dmic_detect参数与声卡问题有关。您可以在这篇 Debian wiki 文章中找到这台机器的其他有用的调整（例如那个mem_sleep_default）。

Ubuntu 20.04 上没有声音（Dell XPS 7390 / Realtek ALC3271 / Intel Corporation Device 02c8）

如何运行 .sh 脚本？

如何安装 .tar.gz（或 .tar.bz2）文件？

如何列出所有已安装的软件包

无法锁定管理目录 (/var/lib/dpkg/) 是另一个进程在使用它吗？
