# ALSA Use Case Manager profiles. Without this package, PipeWire /
# wireplumber see a complex sound card (Intel SOF on Lunar/Meteor/
# Panther Lake laptops, Qualcomm Snapdragon X, AMD ACP DSP, …)
# but have no per-machine recipe for which PCM device is the speaker
# output, which controls to unmute, or how to route on jack-insert.
# Result: ALSA-level audio works (`speaker-test -D plughw:0,2`
# plays), but GNOME / KDE Sound shows "Dummy Output" only.
# Architecture: all package, ~1 MB on disk, inert on simpler audio
# chains (HDMI-only SBCs, USB DAC, etc.), so safe at minimal tier.
