I was playing with ExTweaks and this info comes in handy. Thanks!.

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.

I'm not sure about how can a headset button wake the device from deep sleep.
While phone's is charging - whether it's wall charger or usb charger, enough interrupts are fired from time to time that prevents phone from going into deep sleep, so it will respond to headset buttons.

Great thread! +1 =)

Hi,
once again you amaze us with an extraordinary topic, informative and so easy to read. Thanks a lot. I'll translate in french :). I have a question: is it normal to lose dualboot when flashing a new. Primary rom? The second is still present at/ sdcard/.secondr and I flashed back the Siyah kernel 3.1RC6. THanks in advance.

If the new rom has a kernel other than Siyah, then you lose dual boot only temporarily. Once you flash Siyah, dual boot should be back as long as you haven't done anything to data.img and cache.img inside /sdcard/.secondrom

Second rom /system resides in a hidden partition - mmcblk0p9 and flashing a rom will not do anything to it.

thnks 4 ur answer.

will keep on hoping there is a solution

headset button controller has an option to keep phone awake when headset is plugged. but this is terrible for battery duration
