Hi Martin,
It is possible-- it's just a matter of time and scarcity thereof (in
my case, anyway). If you'd like to file a bug report (doesn't have to be
elaborate), we could see how the community may be able to help:

Hi,
it is possible to toggle some settings like "Enable Audio codec power
management" from "Bad" to "Good" and back again. However, when
exiting
powertop while it is set to "Good", and then re-running powertop, the value is
stuck at "Good", i.e. it is not possible to toggle it to "Bad". When
trying to
do so, the status line only shows ">> (null)" instead of something like
"echo
'' > '/sys/module/snd_hda_intel/parameters/power_save';".
This is probably because sysfs_tunable::bad_value is initialized with "\0" and
does not change its value if it is already set to "Good" when starting up
powertop. When now calling sysfs_tunable::toggle(void), strlen(bad_value) is 0
and the write_sysfs line is not executed.
Is it possible to fix this?
Regards,
Martin Walch
