Asound 找到声卡,但 pavucontrol 没有找到

安装 nix 并重新启动后,我遇到了一个奇怪的错误:我的声卡被找到了(我认为),但我的系统只显示了一个虚拟输出。在此之前,声音工作正常。

$ cat /proc/asound/cards

pavucontrol只显示虚拟输出并且没有声音。

操作系统:Kubuntu 19.04

当我出现类似症状时(在 manjaro 中),这使它再次发挥作用:

mv ~/.pulse/client.conf ~/.pulse/client.conf.old
killall pulseaudio
pulseaudio --start --log-level=4  # or logging out and in should work as well

并等待几秒钟。

我曾经遇到过(现在仍然遇到)由于音频插孔而产生的问题,而不是因为 nix,所以这可能不适合您。
