macOS 环境

Shell 脚本

使用说明

Linux 使用：

# 保存脚本为 check_sound.sh
chmod +x check_sound.sh
./check_sound.sh

Windows 使用：

# PowerShell 脚本
.\check_sound.ps1
# VBScript 脚本（保存为 .vbs 文件）
check_sound.vbs

安装依赖（Linux）：

# Ubuntu/Debian
sudo apt-get install alsa-utils pulseaudio-utils
# CentOS/RHEL
sudo yum install alsa-utils pulseaudio-utils
# Python依赖
pip install pyalsaaudio  # 可选，用于更详细的ALSA控制

这些脚本会检测声卡的硬件信息、驱动状态、设备节点、音频服务状态等,你可以根据实际需求选择适合的脚本来检查声卡状态。
