HDMI 无声音,Ubuntu 16.4.03,Radeon RX550

仅供参考,我是 Ubuntu 新手。我无法通过 HDMI 电缆连接到显卡的显示器获得声音。在我的笔记本电脑(Win10)上,它运行良好。我组装了一台 PC:

  • 主板:技嘉 A320 GA-A320-DS2
  • 中央处理器:AMD RYZEN 5 1600
  • 显示器:HP24es
  • Ubuntu:16.4.03 LTS
  • AMD 驱动程序:amdgpu-pro 17.30-465504

在系统设置/音频中,HDMI 不显示为输出选项,只有 S/PDIF。我试过 pulseaudio,但它显示所有 HDMI 输出选项都未插电。GNOME ALSA Mixer 在 Realtek ALC887-vd 选项卡下取消了所有内容的静音,而 ATI R6xx HDMI 选项卡则不显示任何选项。aplay -l 显示:

aplay -l

我试过了Ubuntu 拒绝通过 HDMI 输出音频, 这https://itsfoss.com/how-to-fix-no-sound-through-hdmi-in-external-monitor-in-ubuntu/和这个:

pacmd set-card-profile 0 output:hdmi-stereo

但到目前为止,什么都没起作用。有什么想法吗?
