Hi. I noticed that powertop 2.4 does not correctly checks if the audio codec power management is already enabled. The module responsible for audio in my sistem is "snd_hda_intel", and powertop requires that "/sys/module/snd_hda_intel/parameters/power_save" is set to 1 to consider that power save is enabled. Since that parameter is the power save timeout in seconds (0 disables power save), it should check if it is greater than 0. In my setup, "power_save" is set to 10 seconds and "power_save_controller" is set to "Y", but powertop still thinks that power save is not enabled for my audio codec. Thank you.
