没有找到音频设备，没有正确的声音

我在Dell Vostro 15笔记本电脑上使用Ubuntu 18.04。在声音设置出人意料地没有发现任何音频设备。这是一个屏幕截图：

以下是输出：-

lspci -nnk | grep -A3 Audio

sudo pactl list short sinks

Failed to create secure directory (/run/user/0/snap.pulseaudio/pulse): No such file or directory

1   alsa_output.pci-0000_00_1b.0.analog-stereo  module-alsa-card.c  s16le 2ch 44100Hz   SUSPENDED

由于这个原因，我不能使用任何声音驱动程序。它总是静音。

该怎么办 ？？？
