我正在使用华硕全系列/X99-A，BIOS 4101 07/10/2019。
有问题的声卡是主板内置的。
这个问题乍一看像是重复这个问题适用于 16.04但公认的答案是内核 4.10 可以修复此问题。但是我使用的是内核 5.4.0，问题仍然存在。
我已经安装并重新安装了 pulseaudio 和所有 alsa 配置文件。我已经遵循了许多方法并将所有这些选项（每个选项一次）添加到/etc/modprobe.d/alsa-base.conf：
options snd-hda-intel enable_msi=1 bdl_pos_adj=0,-1
options snd-hda-intel enable_msi=1 model=auto
options snd-hda-intel model=dell-headset-multi
options snd-hda-intel enable_msi=1 model=auto
在所有可能的组合中。有一种组合（忘记是哪种了）实际上有效了几个月，但后来突然就失效了。
我可以在 alsa 混音器中看到该卡
但它没有出现在 pulseaudio 音量控制中。
我做错了什么？我能尝试什么？我现在应该放弃吗？
谢谢你！

答案1
由于某种原因，只有在启动后完全重新加载 alsa 后 alsa+pulseaudio 才会起作用。
$ sudo alsa force-reload
Terminating processes: 1368.

之后内置音频出现在 pavucontrol 中
然而，每次计算机重新加载时我都必须这样做。
一些其他在线用户建议消除胆怯，以防有读者想尝试，但这对我来说不起作用。
$ sudo apt purge timidity-daemon
令人惊奇的是，现在已经 2023 年了，我仍然必须在 Linux 桌面上执行此操作。
