Intel HD audio codec power management
Solution 1:
To set your time-out 10 seconds (Adjust as you like):
echo 10 > /sys/module/snd_hda_intel/parameters/power_save
You can verify if powersave is on by
cat /sys/module/snd_hda_intel/parameters/power_save_controller
Powertop will always show 100% cpu on those though, it's a known error.
