这可能不止一个问题；在 VLC 中启动 YouTube 视频或视频文件时，音频在播放前会静音约 2 秒。在 Spotify 和其他程序中播放音频时也会出现同样的延迟问题。

然后，在播放视频时，它将正常播放 5 到 10 分钟，有时会更长，但不可避免地音频会中断约一秒钟，并反复中断几次，然后才恢复正常。

我读过一个解决方案，建议将 pulseaudio 配置文件从

## Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle

到

## Automatically suspend sinks/sources that become idle for too long
 load-module module-suspend-on-idle

但是，我似乎无法在 pulseaudio 配置文件中找到这些行

我没有遇到视频播放方面的其他问题。无论显示器刷新率为 60hz 还是 59.94hz，都会出现此问题。我很难诊断此问题。

以下答案解决了音频启动延迟的问题，但未能解决播放过程中偶尔出现的音频丢失问题。感谢用户 h​​ananamar：https://askubuntu.com/a/1438571/721075

音频软件现在是 pipewire，不再是 pulseaudio。因此，@user1115995 的解决方案是禁用 pulseaudio 上的暂停功能，可以使用以下命令为 pipewire 执行此操作：（来源）

sudo sed -i 's/--\["session.suspend-timeout-seconds"\] = 5/\["session.suspend-timeout-seconds"\] = 0/'/usr/share/wireplumber/main.lua.d/50-alsa-config.lua
systemctl restart --user pipewire.service
