我会尽量简短但详细地介绍。在大约三个月的停顿之前，我通过终端运行更新并关闭我的双启动、外部驱动器 Ubuntu 安装，当我最近启动 Ubuntu 时，我看到一个黑色的登录屏幕。我启动恢复并使用“amdgpu.dc=0”更新 grub。这个修复让我没有音频 - 这本来是一个快速修复，只是为了登录，因为我不确定 amdgpu.dc 标志实际上完成了什么。
经过此调整后，设置中识别了 Radeon RX 580 和 HDMI 音频输出，但仍然没有音频，登录屏幕只是视频伪影，而不是标准屏幕。我能够进入桌面环境。
我尝试了全新安装，但“live cd”USB 驱动器无法完成全新安装，并且在安装过程中没有音频。USB Live CD 驱动器/密钥在我的另一台 AMD 笔记本电脑上可以正常工作，因此问题不是坏位或坏的 USB 密钥。这让我相信内核或当前的 AMD 驱动程序是问题所在，因为我的 PC 几个月前运行正常，我最初使用 live cd 安装 20.04.1 时没有问题。
我有最新的内核，但安装/启动了原始发布内核进行测试，没有任何改进。确认一下，大约六个月前，图形和音频通过 HDMI 工作正常。我找不到任何完全解决这个问题的帖子，并且认为开源驱动程序可能无法与我的主板或使用 HDMI 的 Radeon RX 580 配合使用。
任何帮助解决此问题的帮助都将不胜感激。此问题诊断初始阶段的启动修复 Pastebin 可在下面找到：

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda1,
using the following options: sdc1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Blockers in case of suggested repair: __________________________________________
Please use this software in a live-session (live-CD or live-USB). This will enable this feature.
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 20.04.4 LTS CurrentSession entry (sdc1/efi/****/grub****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi (**** will be updated in the final message)
