This fixes the VoLTE and No Audio in Calls bug in all older than 19-05-2018 GSI(Treble based) Roms.
Note: New GSI builds doesn't need call audio patch and will not work properly if you have flashed it, if you are going to flash new GSI builds then restore you vendor to stock state and flash only volte patch

Requirements:

You must be on AospExtended vendor, stock vendor won't work

Instructions:
1. Backup system and vendor (or not, depends on you)
2. Flash any GSI/Treble based rom you want
3. Flash the volte patch
4. Flash the call audio patch
5. Hit Thanx and enjoy

I have a serious issue, there's no sound in calls for me, no matter how I format my device or what ROM I install. (It's definitely not a hardware issue.)

I want to use the phone with LineageOS. Is there any way I can make use of the call sound patch that you uploaded? @Sudeep Duhoon, please help, and thank you sir.
