Pulseオーディオもインストールしましたが、起動しません...

私はインターネット上の他の投稿に出くわしました。そこでは、ubuntu 17.10で音が出ませんが、誰も解決策を投稿しませんでした。前もって感謝します

Linuxカーネルを更新し、現在のMesaドライバーをインストールする必要があります。Ubuntu17.10のRadeon RX560でも同じ問題が発生しました。 Mesa： https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa カーネル： https://github.com/M-Bab/linux- kernel-amdgpu-binaries
