Yes, I agree. I'm debugging this issue on Ubuntu, not sure it happens on other distribution too.
If it's related to Ubuntu, maybe need check Ubuntu power policy. Does anyone know the Ubuntu power-policy on laptop?
i.e. when charger connected, will Ubuntu make decision to disable power-save feature for audio subsystem?
I'm not a power management expert, but I got a pointer from my team mate
to pm-utils:
http://cgit.freedesktop.org/pm-utils/tree/pm/power.d/intel-audio-powersave
If I understand correctly, The scripts in power.d are executed when
battery / AC-power is changed.
Takashi, does SUSE also use pm-utils?
