Stop VBA to block Excel sheet when executing a function - excel

Question

I’ve got following Excel scenario:
A1 has the value of "A", B2 = "B", C3 = "C"
but they are interchangeable.
Within the workbook path there are two subfolders containing wav files named A.wav, B.wav and C.wav
The code at the bottom allows me to playback the wav files with a button click firing the macro PlayIt().
My Problem is, while the function is executing I’m unable to edit cells in Excel which I really need to! It kinda looks like this

Thank you for any help!
Code for Audioplayback:
Option Explicit
#If VBA7 Then
Public Declare PtrSafe Function PlaySound Lib "winmm.dll" _
Alias "sndPlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long
#Else
Public Declare Function PlaySound Lib "winmm.dll" _
Alias "sndPlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long
#End If
Const SND_SYNC = &H0
Const SND_ASYNC = &H1
Const SND_FILENAME = &H20000
Sub PlayTheSound(ByVal WhatSound As String)
If Dir(WhatSound, vbNormal) = "" Then
' WhatSound is not a file. Get the file named by
' WhatSound from the Windows\Media directory.
WhatSound = ThisWorkbook.Path & "\stimuli\" & "\1second\" & WhatSound
If InStr(1, WhatSound, ".") = 0 Then
' if WhatSound does not have a .wav extension,
' add one.
WhatSound = WhatSound & ".wav"
End If
If Dir(WhatSound, vbNormal) = vbNullString Then
Beep ' Can't find the file. Do a simple Beep.
MsgBox "Could not find the file in the Path: " & WhatSound
Exit Sub
End If
Else
' WhatSound is a file. Use it.
End If
PlaySound WhatSound, 0&, SND_ASYNC Or SND_FILENAME ' Finally, play the sound.
End Sub
Sub PlayIt()
PlayTheSound (Range("A1").Value)
PlayTheSound (Range("B1").Value)
PlayTheSound (Range("C1").Value & "e")
End Sub

Answer 1

You have your declaration wrong in two ways: hModule should be LongPtr, and you are using parameters from PlaySound while actually calling sndPlaySound.
Fix your declaration:
#If VBA7 Then
Public Declare PtrSafe Function PlaySound Lib "winmm.dll" _
Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As LongPtr, ByVal dwFlags As Long) As Long
#Else
Public Declare Function PlaySound Lib "winmm.dll" _
Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long
#End If
