+# - PipeWire as the audio server
+# - PulseAudio compatibility via pipewire-pulse
+# - ALSA compatibility (+ 32-bit ALSA for games/legacy)
+# - WirePlumber session manager
+# - RTKit for better realtime scheduling (often reduces crackling under load)
+#
+# IMPORTANT (NixOS option churn):
+# - On some nixpkgs revisions the old `hardware.pulseaudio` option was renamed to
+#   `services.pulseaudio`. We set the *services* one explicitly.
+# - Avoid `lib.mkForce` on pulseaudio enable/disable here because certain revisions
+#   have had type/override weirdness; use plain booleans instead.
