================================================================================
Kernel related data:
Kernel 4.9.0-13-rt-amd64
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Cpu idle driver: intel_idle
================================================================================
Kernel modules data:
Check if pcspkr is loaded: No, which is good!
Check if snd modules are loaded: Yes, may cause bigger latency.
  can probably be disabled in bios, alternatively, you can run
   "./block-snd-modules"
   which has just now been created for your convenience.
