-- Kaisa (sof-rt5682): enable UCM + ACP so HiFi profile / Jack-driven ports work.

-- WirePlumber 0.4.x: appended after stock alsa rules.

-- 若仅启用 use-ucm 而不固定 profile，栈常会默认选 stereo-fallback，界面只剩模拟/耳机，HDMI 消失。

-- 若某台机器在 PipeWire/ACP 枚举阶段暂未暴露 HiFi profile（pactl「配置文件」里看不到 HiFi:），
|

-- 这是安装/时序/内核问题，应修复根因，而不是回退到 pro-audio。
