However, it is still above my understanding whether these settings can solve the infamous Android bug that audio playing cannot be resumed by means of the headset button after the phone has gone deep sleep (at least not with one pause/play click).
This might well be one of the top 5 most annoying android features (judging from non-expert users posts) as it happens on a wide range of android devices.
As a matter of fact, some people's phones work nicely, and this bug does not occur while the phone is charging (although battery stats show the phone is not awake, seems not deep sleeping neither).
Do you guys know whether kernel settings can overcome this issue? or any combination of rom-kernel that solves it?
It's been almost a year now. I have searched for detailed info on this issue but found nothing. Checked the /system/urs/keychars/ files. Tested different kernel-rom combos and now some Governor-CPU Idle Mode combos. No luck.
If after all this is not kernel related and therefore it should not be posted here, I am sorry, please feel free to delete.
