The `l4t-init` package contains a few important ALSA configuration files: - `share/alsa/init/*`: Configures initial Audio Processing Engine (APE) settings on boot - `share/alsa/cards/*`: Sets up APE and HDA audio cards for use with ALSA libraries It would be great if `jetpack-nixos` installed these in their appropriate locations. Unfortunately, the appropriate locations are [yet to be decided](https://github.com/NixOS/nixpkgs/issues/395660).
