Please tell us some basic information before asking for help:
Model Name: zenfone max m2
Firmware Version: WW-17.2018.2004.31
========================================
After building the kernel source provided after stock ten beta, and importing caf sound(techpack) and wifi(prima) drivers, wifi works but sound doesn't work. I'd like to ask if there are any sound driver specific changes done by asus.
Note :- Reason was that, I found a new driver module(audio_tfa9874) which is not in the caf import, implies it confirms there are some more changes done to the kernel source.
I request you to look into this and update the kernel source as soon as possible
Thanking you
