i am going to be of mild help(or no help) on this subject due to i can remember with rom i had installed.but i had the sound problem and it only happened on a particular rom,i could flash to stock or any number of other roms without that problem returning.but then come back with that rom only.
so i recommend a slighlty different version of that rom and its not your phone(however isnt it odd that one person can have a problem with a rom that no one else has,i get problems that i never see addressed by anyone else.)
