It works when manually removing and reloading the module - but still on rebooting it does not. The manual case: merkaba:~> modprobe -r snd_hda_intel merkaba:~> lsmod | grep snd_hda_intel merkaba:~#1> modprobe snd_hda_intel merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save 1 merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save_controller Y Another test for the manual case: merkaba:~> echo "0" > /sys/module/snd_hda_intel/parameters/power_save merkaba:~> echo "N" > /sys/module/snd_hda_intel/parameters/power_save_controller merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save 0 merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save_controller N (I don´t think these above are necessary, but anyway.) merkaba:~> modprobe -r snd_hda_intel merkaba:~> modprobe snd_hda_intel merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save 1 merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save_controller Y Now for the reboot case I disabled the sysfs.conf entry for setting it: merkaba:/etc> vim sysfs.conf merkaba:/etc> grep snd sysfs.conf # Macht modprobe/kmod anhand von /etc/modprobe.d/snd-hda-intel.conf derzeit nicht. #module/snd_hda_intel/parameters/power_save = 1 Then I build a new initramfs with this configuration: merkaba:/etc> cat modprobe.d/snd-hda-intel.conf # c`t kompakt Linux 1/2012 # Thorsten Leemhuis, Notebooks unter Linux, S. 38ff # S. 42, Kasten Handoptimiert options snd_hda_intel power_save_controller=Y power_save=1 merkaba:/etc> update-initramfs -k all -u update-initramfs: Generating /boot/initrd.img-3.2.0-2-amd64 W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
