I'm not able to run 03/04 build on aosp 10 roms on gts4lvwifi and enchilada in combination with viper4androidfx 27xx and AML.
for me 03/04 works on my enchilada with crDroid v6.3 (Android 10)
I'm using this with v4a, jdsp and aml
on Android 10 I have noticed, that you need to install v4a a second time. after the first driver installation and restart, it always ask you to install driver. after second install and restart it works. maybe that's your problem?
try remove all soundmods, install v4a how I described, then narsil and aml as the last one
