[Question] Supported kernels for sound control

[d8f6]

So, I have been using the elementalx kernel for a long time (since 2021) because it works with the setting ( Sound -> Sound Control -> Headphone Gain ). What I wanted to ask is if there are other kernels that now support this feature (assuming phone is rooted) as I need it for the volume increase and not all new phones are supported by the elementalx kernel. I was hoping maybe someone using a stock lineageos (21.xx version) kernel and this app could check this for me? Also, does it only work with certain android/lineageos versions? It is literally the only feature I need. Okay, thanks in advance for any help from the community here.
