Default Skype + AOSP KK ROM + Bluetooth Headset = No Sound :(

I'm trying to use Bluetooth headset with Skype on a non-Samsung KitKat rom, however without any success. When I connect a call, I can hear the phone ring on other side on my Bluetooth headset however as soon as it connects, the headset goes silent. If i switch output to speaker, I can hear them

I've tried many AOSP / CM roms and kernels (including ones based on samsung sources) but all of them have same issue. On stock Samsung Touchwiz 4.3 ROM, it works fine without any issues.

Are there any fixes for it ?
