#NixOS out-of-tree #kernel module for #Apple #CirrusLogic #CS8409 #codec + #TAS5764L amp. The mainline #driver only supports Dell. The file below packages davidjo/snd_hda_macbookpro as a #Nix #derivation. Now the #sound on my old #imac running #linux #nixos seem to work. It did not work before. Tested on #iMac2017 27" (iMac18,x), kernel 6.17, #RadeonRX580. https://codeberg.org/adingbatponder/reticulum_nixos_flake/src/branch/main/packages/snd-hda-codec-cs8409-apple/default.nix Disclaimer: the solution was taken from the references cited in the default.nix file & implemented using #ClaudeCode.
