%description
Model-specific PipeWire/WirePlumber DSP graphs and FIR filters for supported
Apple T2 Macs.

All speaker graphs are kept active with node.always-process=true so short
one-shot sounds are not lost while the DSP graph wakes up. Microphone graphs
retain their upstream idle behavior.

A udev hardware rule detects the T2 audio PCI function on the real machine and
generates the matching WirePlumber configuration. This is safe for live ISOs,
installed systems and non-systemd distributions.
