hello, I've identified some key apps relating to audio that I'm using of which I want to keep the configuration of after the migration to 20.04

Please correct me if I'm wrong about their configurations:
* `alsamixer` - ???
* `qjackctl` - `~/.config/rncbc.org/QjackCtl.conf` / `~/.config/autojack/autojackrc` / `~/.config/jack/conf.xml` (though this conf file says that it will be overwritten when `jackdbus` saves)
* `pulsemixer` / PulseAudio - `/etc/pulse/`
* `ubuntustudio-controls` - ???
