播放开始时声音延迟

我遇到了烦人的音频问题，非常感谢任何帮助！

问题：播放开始时声音延迟 2-3 秒。它仅在空闲后第一次启动时出现，如果我在其中一个正在播放或刚刚停止时在源之间切换，则工作正常。

Manjaro Linux，内核 5.10。英特尔声卡。自动静音已禁用。添加intel_iommu=igfx_off到 grub 参数中。尝试应用解决方案https://wiki.archlinux.org/title/PulseAudio/Troubleshooting，但没有任何帮助（或者我只是错过了一些东西）

提示：在以前的硬件上运行良好。从戴尔 XPS 9570 切换到 9500(i5-8300H -> i5-10300H)

请检查这是否有效：

  1. 注销
  2. Ctrl + Alt + F2 -> 登录
  3. mv ~/.config/pulse ~/.config/pulse.bak
  4. reboot

如果其他人将来发现这个并且它不能解决他们的问题（像我一样），我的黑猩猩大脑解决方法是制作一个静音音频文件并将其设置为循环作为我的第一个提示。这似乎让事物保持活力，因此其他线索会立即触发。
