[alsa-devel] snd-hda-intel: Power management not enabled until audio is played

Dear ALSA folks,
playing with PowerTOP 1.97 I notice that it lists 100 % usage for the
Audio device on several systems [1].
I made sure that power management is enabled.
$ grep snd /etc/modprobe.d/*
…: options snd_hda_intel power_save=1
$ more /sys/module/snd_hda_intel/parameters/power_save_controller
Y
$ more /sys/module/snd_hda_intel/parameters/power_save
0
Since I was on AC power pm-utils seems to reset that parameter to not
save power. :/
$ sudo su
# echo "1" > /sys/module/snd_hda_intel/parameters/power_save
# exit
But enabling that does not change anything right away. Only after using
the device by playing some audio – `speaker-test` in this case, the
power management seems to kick in.

Is that an error in the driver? I have seen that with Realtek and
Conexant devices. Please also find the output of `alsa-info.sh` [2]
attached. There is no difference before and after playing some audio.
