[Q] My ported lewa has no sound during call

I choose LeWa_AMOI_N828_JB2 as port ROM and my ZTE U956's rom as base rom.They all have a mt6589 chip.
I replace these files:
/etc/firmware
/system/lib/libcameracustom.so
/system/lib/modules
/system/build.prop
/usr/keychars
/usr/keylayout
boot.img
It boots successfully and has almost no bug except this sound problem.

[PORTING] Stuck on a boot logo when porting roms

Hello guys, i have a Samsung Galaxy A3 2016 (SM-A310F) and my stock rom is Advanced three (Ported from advanced seven for a7 2016 that is ported from note7) and i want to port this rom:
https://forum.xda-developers.com/samsung-a-series/development/rom-a5-2017-grace-ux-t3531719 from A500G 2015.
I ported this and got bootloop.
I tried the fix with replacing the lib files.
But unfortunately this method didn't work too. Can you please help me? I don't have any ideas how to fix this.
