Ubuntu 似乎无法识别我电脑上的任何音频输出端口。我有常用的内置后面板（彩色）和前面板（麦克风和耳机）插孔，以及通过 NVIDIA 显卡的 HDMI 端口进行音频输出。以下是我在其他相关线程上找到的一些命令的输出，我曾使用这些命令尝试调试我的问题：
~$ sudo lspci -v | grep -A7 -i "audio"

这里alsa-info.sh是alsa-project 提供的脚本的输出。
从设置菜单的“声音”部分，除了“虚拟输出”之外没有显示任何音频设备，我猜这与 pulseaudio 守护进程有关。
我尝试过卸载并重新安装alsa-base，pulseaudio以及indicator-sound，删除~/.config/pulse，删除alsa-base.conf然后重新安装，但似乎没有任何帮助。
提前感谢任何帮助！
