It aims to offer capture and playback for both audio and video with minimal latency and support for PulseAudio-, JACK-, ALSA- and GStreamer-based applications. PipeWire has a great bluetooth support: because Pulseaudio was [https://github.com/NixOS/nixpkgs/issues/123784 reported to have troubles with bluetooth], PipeWire can be a good alternative.

If you are still using 23.11 or earlier, you can specify these files in <code>environment.etc</code>:
It is possible change a particular user instead of system-wide, with adding this to <code>~/.config/wireplumber/bluetooth.lua.d</code> instead, manually or using Home-Manager.
