# Chromebox 10 代 - 原生 ChromeOS 音频硬件拓扑收集脚本（增强版）
|
||
# 用于 C1c 任务：在原生 ChromeOS 下收集硬件拓扑，供与 Coreboot+Linux/Windows 对比
|
||
#
|
||
# 用法（在 ChromeOS 上）:
|
||
# 1. 打开 crosh：浏览器按 Ctrl+Alt+T
|
||
# 2. 输入 shell 进入 bash（如果提示符是 crosh>，输入 shell 后回车）
|
||
# 3. 将本脚本保存到 Downloads 目录（通常路径为 /home/user/xxxxxxxx/MyFiles/Downloads/）
|
||
# 4. 在 shell 中执行：bash 脚本文件名.sh
|
||
# 5. 执行完成后，在同目录生成 audio_topology_chromeos_*.txt 文件
|
||
#
|
||
# 示例：
|
||
# Welcome to crosh, the ChromeOS developer shell.
|
||
|
||
# If you got here by mistake, don't panic! Just close this tab and carry on.
|
||
|
||
# Type 'help' for a list of commands.
|
||
|
||
# If you want to customize the look/behavior, you can use the options page.
|
||
# Load it by using the Ctrl-Shift-P keyboard shortcut.
|
||
|
||
# crosh> shell
|
||
# Sudo commands will not succeed by default.
|
||
# If you want to use sudo commands, use the VT-2 shell
|
||
# (Ctrl-Alt-{F2/Right arrow/Refresh}) or build the image with the
|
||
# login_enable_crosh_sudo USE flag:
|
||
|
||
# $ USE=login_enable_crosh_sudo emerge-$BOARD chromeos-login
|
||

# cat audio_topology_chromeos_*.txt # 直接查看
|
||
# 或用 ChromeOS 的文件应用打开 Downloads 目录找到该文件
|
||
#
|
||
# 注意：
|
||
# - ChromeOS 使用 CRAS 音频服务器，无 PulseAudio
|
||
# - 部分信息需在浏览器打开 chrome://system，找到「audio」一节点击 Expand
|

# - 将展开的内容复制粘贴到输出文件末尾的指定位置
|
