I’ve got a set of speakers with a particularly hot external amp. Putting a 0 in /sys/module/snd_hda_intel/parameters/power_save and an N in /sys/module/snd_hda_intel/parameters/power_save_controller makes this problem go away. It did on Mint, and it does on Fedora. This change isn’t permanent, you have to add a line to some config file, I’ve found instructions online to add the same options snd-hda-intel power_save=0 power_save_controller=N line to three different .conf files, none of them do anything. Weirdly I end up with a 1 and a 0 in the power_save file.
How do you fix this on Fedora?
