# 将系统尽量恢复到某次 capture-ubuntu-audio-baseline 采集时的「安装 deb 前」文件状态。
|
||
# 典型：purge kaisa-hdmi-pipewire-fix → reinstall alsa-ucm-conf → 可选解压备份 tar。
|
||
# 用法：./scripts/restore-ubuntu-audio-baseline.sh [基线目录]
|
||
# 若不传参数，使用 audio_topology/baseline-stash/ 下最近修改的子目录。
|
||
# 需要：sudo（apt、解压到 /）；建议在桌面会话下执行以便重启 PipeWire。
