The sndPlaySound API expects to be passed a string telling it what file to play, not a byte array.

You could read your res file, write that data to a temp file, and then play the temp file.

    Dim data() As Byte
    data = LoadResData(101, "AA") ' or use
    Open "Temp.wav" For Binary Access Write As #1
    Put #1, , data
    Close #1
    sndPlaySound "Temp.wav", SND_ASYNC Or SND_NODEFAULT Or SND_MEMORY

Just delete the file when you are done with it.  I'm sure if there is a way to directly play a file stored in a byte array in memory.
