This is asked and answered often.  Read the previous posts.  That's why they
are saved.

Here is a past post of mine on this subject.

You should be able to find something in here to help.

Follow this link to Allen Browne's site:

1. Create a new module and add in the code as instructed
2. Then just add code like this to whatever event you
want. Such as GotFocus or something.

=PlaySound("C:\StarWarsTheme.WAV")

Make sure you include the full path and extension.

There is also code here:

Example usage like so:

Let's assume you have a field in the table called PathToSoundFile and you
have a corresponding control on the form bound to that field called
txtPathToSoundFile. The code behind the command button would now
look like this:

' *******Code Start*********
Private Sub cmdPlaySound_Click()
On Error GoTo ErrorPoint

   Dim strPath As String

   If Len(Nz(Me.txtPathToSoundFile, "")) = 0 Then
       ' No sound file path present so just ignore
       ' You could also play a "No Sound" file
       ' or a Windows one if desired
   Else
       ' Sound file path present
       strPath = Me.txtPathToSoundFile
       fPlayStuff (strPath)
   End If

ExitPoint:
   Exit Sub

ErrorPoint:
   MsgBox "The following error has occurred:" _
   & vbNewLine & "Error Number: " & Err.Number _
   & vbNewLine & "Error Description: " & Err.Description _
   , vbExclamation, "Unexpected Error"
   Resume ExitPoint

End Sub
' *******Code End*********

This will work with forms in Single or Continuous layout.
You optionally could save the record first if you desire as well.
