How Can I Play a Sound in WinPE During Imaging?

Out of curiosity, what task are you trying to alert people about in WinPE? Is it to notify users when input is needed for a GUI? Maybe a bright background color could also signal when action is required, which might be visible enough for techs to notice.

If it's just to signal progress, consider using TTS to announce each step. Otherwise, you might want to set up notifications through Slack or Teams for a different approach. WinPE likely lacks audio support by default, so you'll need to add components to get it running.
Also, changing your background to a bright color during specific steps could grab attention instead of sound.

You really need .NET framework for PowerShell to work properly in WinPE, which isn’t included by default. Plus, you'll need to add some system files.

You can use the System.Console class and do something like this:

```powershell
[Console]::Beep(1000, 500)
```
Or to play WAV files, try using System.Media.SoundPlayer as an alternative.

You might need the full PowerShell script if you're looking to do more than just basic beeps. Here's a more comprehensive version:

```powershell
Add-Type -TypeDefinition @'
using System.Runtime.InteropServices;
[Guid("5CDF2C82-841E-4546-9722-0CF74078229A"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IAudioEndpointVolume {
// Other COM methods, etc.
}
'@
::Mute = $false
::Volume = 1
[console]::beep(500,300)
```
Give it a shot, and see if that works!

You can give this a shot in WinPE:

```powershell
::Mute = $false
::Volume = 1
[console]::beep(500,300)
[console]::beep(500,300)
```
Just test it out since the support might vary!
