android kernel question lineageos

So, I'm wondering if there is any way to get headphone gain settings working in smartpack kernel manager on a vanilla lineageos install. I know it works with elementalx kernel. If I want this setting do I need to compile a lineageos kernel myself and enable a setting somewhere? Is this feature specific to a patch?

Haven't used custom kernels in ages, but why not just use Wavelet? It's made by the same guys who made Viper4Android.
- I see what you mean, but I don't need an equalizer. I am trying to increase the volume threshold itself. I used to use mixer_paths.xml for this years ago, but even doing that is getting complicated (magisk overlayfs is needed now I guess?). I prefer the smartpack way though as it can be changed on the fly.
  
  Wavelet is more than just an equalizer though, you can use it to raise just the gain, like you wanted - and it can be changed on the fly, and doesn't even need root.
have you tried edit /system/vendor/etc/mixer_paths.xml file ? it may include volume and gain config
- Yeah, that will have to be the way. I looking into lineageos stock kernel and the paths for smartpack kernel manager do not exist. Probably just run outdated software instead for now.
  
  afaik gain control sysfs is not a part of vanilla linux kernel. so you may need to port some patch from elementalx kernel, rather than just simply enable some kernel config
