需求

防止我在梦中惊醒，一怒之下整了这个脚本

实现

  1. 实现锁屏静音🔇，解锁恢复
  2. 锁屏前就是静音状态，则解锁保持静音🔇
  3. 接住AudioDeviceCmdlets模块，运行几乎无压力

代码

把下面代码用自带记事本保存，文件名（包括扩展名）改成 SetupMuteOnLock.ps1 并使用管理员权限运行。

# 需要以管理员权限运行
if (-not ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
    Write-Host "请以管理员权限运行此脚本！" -ForegroundColor Red
    Start-Sleep -Seconds 3
    exit
}

Write-Host "正在设置锁屏自动静音功能..." -ForegroundColor Green

# 创建脚本目录
$scriptDir = "$env:USERPROFILE\LockScreenMuteScripts"
if (-not (Test-Path -Path $scriptDir)) {
    New-Item -Path $scriptDir -ItemType Directory | Out-Null
}

# 检查AudioDeviceCmdlets模块是否安装
$moduleInstalled = Get-Module -ListAvailable -Name AudioDeviceCmdlets
if (-not $moduleInstalled) {
    Write-Host "安装AudioDeviceCmdlets模块..." -ForegroundColor Yellow
    Install-Module -Name AudioDeviceCmdlets -Force -Scope CurrentUser
    Write-Host "AudioDeviceCmdlets模块安装成功！" -ForegroundColor Green
}

# 获取当前状态

# 保存状态到文件

    `$savedState = Get-Content -Path "$env:USERPROFILE\volume_state.txt"
    `$wasMuted = [System.Convert]::ToBoolean(`$savedState)
  
    # 如果之前没有静音，则恢复
    if (-not `$wasMuted) {
        Set-AudioDevice -PlaybackMute `$false
    }
}
