Hello! I have some bluetooth headphones that I believe support aptX codec (Jabra Elite 45h). Any idea on how to enable that codec for pipewire? I use GNOME and NixOS 24.05.
On my PC i just have pipewire and pipewire.pulse enabled.
Connected headphones automatically have their codecs listed in sound options in Gnome. In my case LDAC is automatically configured.
aptx should be enabled by default, so your device likely does not support it (I assume you got the codec info from pavucontrol).
You can enable specific codecs like so: dotfiles/nixos-config/default.nix at a31d74856710936b398318062f0af6616d994eba · TLATER/dotfiles · GitHub
Configuration spec is here: Bluetooth configuration — WirePlumber 0.5.5 documentation
