我刚刚将系统从 17.04 升级到 17.10。升级后，系统上的任何输出（模拟输出或通过 gpu 的 hdmi）都没有声音。
在设置下的声音选项卡中没有列出设备。

我也安装了脉冲音频但它没有启动......
我在网上看到其他帖子说 ubuntu 17.10 没有声音，但没有人发布解决方案...有人知道如何解决这个问题吗？提前谢谢

您需要更新 Linux 内核并安装当前的 Mesa 驱动程序，我在 Ubuntu 17.10 上使用 Radeon RX560 时也遇到了同样的问题，它可以正常工作！Mesa： https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa 核心： https://github.com/M-Bab/linux-kernel-amdgpu-binaries
