系统更新后音频停止工作

系统更新后音频停止工作

我正在使用 KDE Neon,在上次系统更新后,pkcon update我的音频完全停止工作。我的扬声器和耳机都没有发出声音,并且 Audacity 无法通过我的麦克风检测到声音,尽管所有其他测试似乎都表明我的音频硬件存在并且连接正确。我已重新启动到 Windows 10,以确认这不是一些奇怪的音频硬件故障;那里的声音效果很好。

它也影响我系统上的其他行为,这也有点奇怪。如果我尝试播放测试声音,例如系统设置中的声音,从视觉上看,它的挂起时间比应有的时间要长得多,如果某些东西只是静音或停用,这不是预期的结果。同样,YouTube 视频也拒绝播放和挂起,除非我关闭pulseaudio。

我一直在尝试过去两天内遇到的所有可能的解决方案,包括:

  • 检查 alsamixer 的静音通道
  • 重新启动
  • 重新启动pulsaudio
  • 强制重新加载alsa
  • 添加options snd-hda-intel model=generic到某些文件
  • 重新安装pulseaudio和alsa
  • 杀死脉冲音频
  • 尝试用 Pipewire 替换pulsaudio但失败,然后又退回到pulseaudio
  • 删除我的pulseaudio配置文件
  • 也许还有其他一些我现在不记得的事情。

此时我已经完全不知所措,无能为力了;我将不胜感激任何帮助。

以下是类似论坛帖子被要求提供的一些信息:

更新:我找到了一种能够使用 Linux 获得任何音频输出的方法:环回混合。如果我在 alsamixer 中打开它,我可以听到麦克风的输出。音量可以通过 alsamixer 中的耳机麦克风音量滑块控制,但不能通过主音量滑块或耳机音量滑块控制。

答案1

事实证明,这实际上是 Linux 内核驱动程序最近更新的问题。从内核 5.19.0-38 降级到内核 5.15.0-69 完全恢复了音频;没有必要降级 ALSA 库。感谢你的帮助!
