# Framework Laptop 13 (AMD Ryzen AI 300 Series): the ACP PDM digital-mic driver
# returns saturated full-scale garbage, a known and still-open kernel bug on
# Strix Point and Krackan Point. Framework community threads:
#   https://community.frame.work/t/81866  (Krackan Point, SOF/ACP timeline)

# With UCM on, PipeWire exposes only that broken DMIC as the internal mic. Turning
# UCM off makes the ALC285 codec fall back to its analog-stereo profile, whose
# Internal Microphone pin works. Remove this file and restart wireplumber to revert.

# The standalone ACP PDM card (the broken digital mic) still appears without UCM;
# disable it so no app or default-selection can pick it. The ~ prefix makes the
# match a regex over the card name rather than one PCI path (pci-0000_c1_00.5 on
# velox), so the same board with a renumbered bus is still caught.
