这很有趣，因为之前我的设置完全相同，但我必须将我的主板和处理器发送给保修。之后，我的声音消失了。特别是试图让耳机输出工作。 我的预感说NVIDIA的HDMI与这个问题有关，但我还没能找到问题所在。我使用默认的DVI电缆。
我已经重新安装了我的Arch Linux几次，但问题仍然存在。
我检查过以下内容：
speaker-test -c2＆lt; - 由于某种原因播放和工作。这是唯一有效的方法。
aplay test-wav-file.wav＆lt; - 播放但听不到任何声音。
alsamixer（unmuted，fiddled，everything

尝试安装PulseAudio
sudo pacman -Sy pulseaudio
SystemD应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。
