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?

have you tried edit
/system/vendor/etc/mixer_paths.xmlfile ? it may include volume and gain configYeah, 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 Probably just run outdated software instead for now.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
