我碰巧有一台便宜的 Thomson TH12-N2.32 上网本，在重新安装 Linux Mint 20 XFCE 后，内部扬声器的声音无法正常工作，这让我抓狂。
首先，首先是规格：

我使用 Linuxium（重新）安装了操作系统isorespin.sh我使用 Linuxium 的脚本http://www.linuxium.com.au/how-tos/creatingpersonalizedubuntumintanddebianisosforintelminipcs）与--atom选项（因此生成linuxium-atom-linuxmint-20-xfce-64bit.iso）
我拉黑名单snd_hdmi_lpe_audio了/etc/modprobe.d/blacklist_hdmi.conf，没用。
但是，我没有听到任何声音，尽管所有相应的指示器都pavucontrol表现得好像声音正确发出一样。我知道硬件很好，因为我之前（2019 年夏天，IIRC）设法使声音与以前的 Linux Mint 版本一起工作，尽管我不记得我使用了哪些调整/如何做到这一点。
无论如何，该设备在正确关闭/重新启动方面也存在问题。
我尝试过的：
- 使用几种不同的内核（hwe、edge、lowlatency 等）
- 重新安装以前的 Linux Mint 版本 (19.3)
- 插入耳机（感谢@terdon）：声音出来
