I don't know if it is related or not but you set the timeout to 2 seconds. Change to -1 to disable the timeout.

Where is aplay? perhaps you need the fullpath of aplay as cmd, it looks like :

sh.Initialize("sh", "/...fullpath.../aplay", Array As String(path))

Search Google for this error. Looks like a common error.

Maybe related to a file permission problem.

Could you play it in terminal cmdline

aplay /home/admins/tempja

if yes , you should use path instead of URI

sh.Initialize("sh", "aplay", Array As String("/home/admins/tempjars/Record/11012023094449.wav"))

This code I have tested on my ubuntu. it works.

Sub AppStart (Args() As String)
    Dim shl As Shell
    shl.Initialize("shl", "aplay", Array As String("/tmp/01.wav"))
    shl.WorkingDirectory = "."
    shl.Run(10000) 'set a timeout of 10 seconds
    StartMessageLoop 'need to call this as this is a console app.
End Sub


Sub shl_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
    If Success And ExitCode = 0 Then
        Log("Success")
        Log(StdOut)
        Log("Result: " & StdErr)
    Else
        Log("Error: " & StdErr)
    End If
    ExitApplication
End Sub

If it does not work , try run it as root

Open terminal and write the following then check if it works. Write this:

sudo chmod -R o=rwx /home/admins/tempjars/Record
