AOSP ROMs and VOIP (e.g. skype) topic

Hello all I was wondering if anyone had any conclusive advice on whether, and if they do, how, AOSP ROMS have working voip?

Got my G2 recently and have tried blisspop, ressurectionremix and cm12. I have settled on cm12 but a recurring theme a month these LP CM AOSP based roms is that my mic doesnt work in skype. I can see and hear the other person and they can see me but can't hear me. I know this is has been discussed in threads but there are conflicting reports on whether it is working or not.

D802 bought on 4.4.2
ioRoot and Autorec
Flashed a JB bootloader, stayed on the KK baseband as cm12 can take either KK or JB
Flashed CM12

Have tried the audio policy fix found on resurrection remix rom thread (2nd post) and didnt work, neither has flashing a JB baseband. Was wondering if anyone had got skype working on a lollipop AOSP rom and how?

nb/ some people report distorted mic and some report mic not working. to clarify, my problem is the latter
