linux - 音频在 Arch Linux 中不工作，我的声音消失了

Question

这很有趣，因为我之前有完全相同的设置，但我必须寄回我的主板和处理器以保证更换。之后我的声音就消失了。特别是试图让耳机输出正常工作。我的直觉是 NVIDIA 的 HDMI 与这个问题有关，但我还不能确定问题所在。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。

我检查了以下内容:

• speaker-test -c2 <- 出于某种原因播放和工作。这是唯一有效的方法。

• aplay test-wav-file.wav <- 播放但听不到任何声音。

• alsamixer(取消静音，摆弄，一切

• asoundconf set-default-card SB(主板芯片)。

尝试安装 PulseAudio

sudo pacman -Sy pulseaudio

SystemD 应该检测到它已安装并在您下次重新启动时启动它。然后你应该有声音。
