ubuntu 17.10没声音
我刚刚将系统从17.04升级到17.10。 升级后，我的系统上没有任何声音输出（模拟输出或hdmi通过gpu）。
在设置下的声音选项卡中，未列出任何设备。

我也安装了脉冲音频，但它没有启动……
我在互联网上看到其他post，人们在ubuntu 17.10上没有声音，但是没有人发布解决方案……有谁知道如何解决这个问题？ 先感谢您
您需要更新Linux内核并安装当前的Mesa驱动程序，我在Ubuntu 17.10上遇到了与Radeon RX560相同的问题，它可以工作！ Mesa： https ： //launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa内核： https ： //github.com/M-Bab/linux-kernel-amdgpu-binaries
