内置扬声器无声音，只有“虚拟输出”作为输出设备

我试过了

$ echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
$ echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf
$ echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf

and

$ sudo apt-get install --reinstall alsa-base pulseaudio
$ sudo alsa force-reload

and

$ sudo apt purge timidity-daemon

和

在 /etc/default/grub 中添加了 snd_hda_intel.dmic_detect=0，但没有成功

Xubuntu 检测 HDMI 声音硬件和麦克风。

这是有关系统、硬件和模块的一些命令的输出。
