Default in-call wired headset volume control

Hi im looking for rom based on android 2.2 or 2.3 with working in-call volume control via wired headset. I'm tested multiple rom's and in evry rom problem is the same, i can't adjust volume It's always on the same level although the indicator on the screen changes its position.
Another solution would be to edit the file responsible for the power of headphones during a call. And add some more db to be able to hear loud like in normal phone call.

P.S sorry for my poor english.
