function Set-SpeakerVolume { <# .SYNOPSIS Sets the speaker volume. .DESCRIPTION Sets the speaker volume. .PARAMETER Volume An integer value from 0 to 100 that will set the volume level of the speaker. .EXAMPLE Set-SpeakerVolume -Volume 80 Will display nothing and set the speaker to 80% .EXAMPLE Set-SpeakerVolume -Volume 97 -Verbose Will diplay the following while setting the speaker to 96% VERBOSE: You specified the speaker volume should be 97% VERBOSE: Rounding down to 96% VERBOSE: Turning volume down to 0% VERBOSE: Turning volume up to 96% .NOTES Renamed function from Set-Speaker to Set-SpeakerVolume to be clearer as to the purpose. Set an alias for the function to 'Set-Speaker' for backward compatibility. The interface to setting the speaker volume really accepts values 0-50, and displays as 0-100. Given this oddity, the function will round DOWN to an even number. So if you run Set-SpeakerVolume -Volume 99 The icon for the speaker will display 98% if you hover over it. #> [CmdletBinding(DefaultParameterSetName = 'Volume', ConfirmImpact = 'Low')] [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseShouldProcessForStateChangingFunctions', '')] [alias('Set-Speaker')] Param( [Parameter(ParameterSetName = 'Volume', ValueFromPipeline, HelpMessage = 'Enter the speaker volume from 0-100')] [ValidateRange(0, 100)] [int] $Volume = 50, [Parameter(ParameterSetName = 'Adjust')] [ValidateRange(-100, 100)] [int] $Adjust ) begin { Write-Verbose -Message "Starting [$($MyInvocation.Mycommand)]" Write-Verbose -Message "ParameterSetName [$($PsCmdlet.ParameterSetName)]" } process { switch ($PsCmdlet.ParameterSetName) { 'Volume' { Write-Verbose -Message "You specified the speaker volume should be $Volume%" if (($Volume % 2) -ne 0) { $Volume = $Volume - 1 Write-Verbose -Message "Rounding down to $Volume%" } [int] $workingVolume = [math]::floor($Volume / 2) $wshShell = New-Object -ComObject wscript.shell Write-Verbose -Message 'Turning volume down to 0%' 1..50 | ForEach-Object -Process { $wshShell.SendKeys([char]174) } if ($workingVolume -gt 0) { Write-Verbose -Message "Turning volume up to $Volume%" 1..$workingVolume | ForEach-Object -Process { $wshShell.SendKeys([char]175) } } } 'Adjust' { Write-Verbose -Message "You specified the speaker volume should be adjusted $Adjust%" [int] $workingVolume = [math]::floor($Adjust / 2) $wshShell = New-Object -ComObject wscript.shell if ($workingVolume -lt 0) { $workingVolume = $workingVolume * -1 1..$workingVolume | ForEach-Object -Process { $wshShell.SendKeys([char]174) } } elseif ($workingVolume -gt 0) { 1..$workingVolume | ForEach-Object -Process { $wshShell.SendKeys([char]175) } } } } } end { Write-Verbose -Message "Ending [$($MyInvocation.Mycommand)]" } } |
