这很有趣，因为我以前有完全相同的设置，但我不得不发送我的主板和处理器，以取代担保。在那之后我的声音消失了。尤其是想让耳机输出正常工作。
我的预感是NVIDIA的HDMI与这个问题有关，但我还不能确定问题的确切位置。我使用默认的DVI电缆。
我已经重新安装了ArchLinux几次，但问题仍然存在。
我已经检查了以下内容：
扬声器测试-c2aplay test-wav-file.wavalsamixer（未静音，拨弄，一切
asoundconf设置默认卡SB（主板芯片）。

最佳答案
尝试安装PulseAudio
sudo pacman -Sy pulseaudio
SystemD应该检测到它已安装，并在下次重新启动时启动它。你应该有声音。
