Kernel related data:
Kernel 6.12.12+bpo-rt-amd64

Cpu idle driver: intel_idle
================================================================================
Kernel modules data:
Check if pcspkr is loaded: Yes, may cause bigger latency.
  can be eliminated using:
  sudo echo "install pcspkr /bin/true" >/etc/modprobe.d/pcspkr.conf
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.
