我在 Kubuntu 18 中修复音频时遇到了一些问题（Kubuntu 16 也是如此）。托盘中唯一的声音设备是“虚拟输出”
kosyakov@kosyakov-XPS13:~$ sudo lspci -v | grep -A 10 -i audio
00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21) (prog-if 80)
Subsystem: Dell Sunrise Point-LP HD Audio

然而，
kosyakov@kosyakov-XPS13:~$ aplay -l
aplay: device_list:270: no soundcards found...
到目前为止，我尝试的是重新加载 alsa 服务、重新加载 pulseaudio 以及所有其他流行的建议和教程。

我拥有的设备有：
kosyakov@kosyakov-XPS13:~$ sudo find /dev/ | grep snd
/dev/snd
/dev/snd/seq
/dev/snd/timer
到目前为止，我还不知道如何让 ALSA 检测我的卡。我很感激您的想法。
