所以我的 Ubuntu 出现了这个奇怪的声音问题。播放 YouTube 或 Spotify 上的歌曲时，我可以听到音乐和环境声音，但最终我听不到任何声音。
当我重新启动计算机时，一开始它工作正常。但过了一段时间，声音变得越来越小，最后我根本听不到声音。
这真的很烦人。有人知道如何解决这个问题吗？

答案1
硬件问题
事实证明这是由于耳机损坏而导致的硬件问题。但是，对于其他用户，可以考虑使用软件解决方案。
软件问题
有一些卡拉 OK 声音处理程序，可以将声音从音乐中去除。请检查您是否安装了以下任何程序，并且这些程序在未经请求的情况下正在运行：
答案2
您有 5.1 系统吗？声音通常通过“中央”声道进行编码。我不排除该扬声器存在硬件问题。（我自己也遇到过这种情况。）
答案3
也许您的 ALSA 尚未被 Intel ICH7 声卡检测到。
尝试添加blacklist i82975x_edac到/etc/modprobe.d/modprobe.conf并制作modprobe -r i82975x_edac，然后使用重新启动alsa force-reload。
或者，在你的音频设置上说：
state: SUSPENDED
suspend cause: IDLE
我认为您尚未禁用空闲时挂起模块。请尝试添加#文件/etc/pulse/default.pa。从load-module module-suspend-on-idle到#load-module module-suspend-on-idle。
然后使用 终止脉冲守护进程pulseaudio -k并重新启动sudo init 6。
希望这可以帮助。
