Package: pulseaudio
Version: 2.0-6
Severity: normal
Dear Maintainer,
* What led up to the situation?
My fan is very noisy and my running time is highly reduced because my sound
device is using 100% of power (shown using powertop)
* What exactly did you do (or not do) that was effective (or
ineffective)?
When
echo 1 > /sys/module/snd_hda_intel/parameters/power_save
and
echo Y > /sys/module/snd_hda_intel/parameters/power_save_controller
and pulseaudio restarted, the problem is resolved.
Unfortunately, it is impossible to make it automatic. The value is always set
to default values 0 and N.
If the power supply is unplugged, it also disappears.
Many relative problems have been discussed here:

* What was the outcome of this action?
We must repeat the same action after each start of the computer.
* What outcome did you expect instead?
To get rid of this bug :)
