我安装了标准的 Ubuntu 12.10 64 位。使用 X.Org X 服务器 - 来自 xserver-xorg-video-ati（开源测试）的 AMD/ATI 显示驱动程序包装器，我可以通过 hdmi 将视频图像传输到电视上，但当我将声音切换到 HDMI 硬件时，音频无法通过。我尝试过“fglrx-legacy”修复，但这是“ATI 6620G”，该修复主要针对 4000 系列及更早的版本，因此没有成功。 顺便说一句，这不是 Ubuntu 12.04 和 Catalyst 控制中心的问题
答案1
sudo apt-get remove --purge xorg-driver-fglrx fglrx fglrx-update
sudo apt-get install fglrx
sudo aticonfig --initial
sudo shutdown now -rf
现在它运行得非常好
