Power Saving - audio disable

    • Power Saving - audio disable


      I have a J4005 Gigabyte Mainboard with 2x 4 TB HDD NAS and 300 W Pure Power be quit!
      I have in a idle mode 30 Watt and in Stand by with /usr/sbin/rtcwake -m mem 15 Watt.
      I want to improve this values:
      I try to disable the internal sound card. I read that it is possible to use a blacklist of moduls.
      This command shows moduls which are related to sound.
      lsmod | grep '^snd' | column -t

      Which module I have to put to the blacklist?

      Every suggestion from powertop is enable.
      Do you have other ideas to improve the standby or idle power consumption?

      Thank you,
