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.

Right, it's a known issue. You don't have to play actually but just
opening/closing a device should suffice.
The reason is that changing the sysfs parameter file would change only
the variable but doesn't trigger the event by itself. It's possible
to add some triggering action, but it'd become fairly messy. So I've
postponed the implementation, so far.

Should I submit a bug report to track that issue?

Is `touch /dev/dsp` enough? I am thinking about adding that command to
some start script.

Understood. I guess most users do not experience that since nowadays the
login manager plays some sound opening the device every start up. Mostly
advanced users will suffer from this not using such a login manager or
desktop environment like GNOME or KDE.
Thanks,
Paul

No need for that. It's a missing feature but no bug.

I'm not sure whether "touch" program actually works for a device
file. Playing a sound like "echo -n | aplay" would work.
