+Package: kaisa-hdmi-pipewire-fix
+Version: 0.3.0
+Architecture: all
+Maintainer: chromebox_10th_audio_driver <maintainers@local>
+Installed-Size: 56
+Depends: wireplumber, alsa-utils, alsa-ucm-conf, init-system-helpers (>= 1.52)
+Recommends: pipewire-pulse | pipewire-pulseaudio
+Section: sound
+Priority: optional
+Description: Google Kaisa HDMI audio fix (PipeWire / sof-rt5682, UCM2)
+ Installs UCM2 overlay under /usr/share/alsa/ucm2/ (conf.d/sof-rt5682,
+ GoogleKaisa/sof-rt5682) for Jack-driven HDMI routes plus IEC958 sequences,
+ and a system-wide WirePlumber drop-in (pro-audio profile, HDMI sink
+ priorities). Does not ship helper binaries or user systemd units yet —
+ use manual pactl/amixer steps in OPERATION until automated restore is ready.
+ UCM-first and pro-audio WirePlumber are mutually exclusive — see
+ /usr/share/doc/kaisa-hdmi-pipewire-fix/README.md and OPERATION.
+ .
+ PCI path in the WirePlumber fragment targets BDF 0000:00:1f.3; edit under
+ /etc/wireplumber/ if needed. See OPERATION_PipeWire_Kaisa_HDMI.md.gz in
+ /usr/share/doc/.
