Ubuntu 18 没有声卡

Ubuntu 18 没有声卡

同事,

我不确定,但我认为更新导致了这个问题。我有“假声音输出”(PC 中基本上没有音频),并在帖子上尝试了几个命令,但没有成功。这是我的系统(Ubuntu 18.04.1 LTS)

  • 处理器:Intel core i5-8400 CPU @ 2.8 GHz x 6
  • 显卡:英特尔高清显卡(Coffeelake 3x8 GT2)
  • GNOME:3.28.2
  • 操作系统:64位

以下是一些命令

lshw-C 多媒体

我有一台华擎主板 H310M-HDV,它显示 7.1CH 高清音频(Realtek ALC887 音频编解码器),顺便说一句,在 realtek 中找不到此编解码器

谁能帮我?
