How to add background music?

I took my time testing the PlayWavLoop.dll, the problem is that most .wav files are not coded in pcm, only some very short ones(2 or 3 seconds)

The library could be a good contribution if it worked properly.

And with the Sound() function in B4P, it works with the WAV files who doesn't work with my lib?

With the Sound() function plays every second wav file(surprizingly) ...I was
expecting the function to work well.
Many wav files that won't play with the PlayWavLoop.dll play well with the
Sound() function.

Anybody else cares to share their experience on this issue???

Can you upload an wav file example who doesn't run with my Lib?
I'll try to fix this problem

Edit:
I found an other way for Play wav files... But there'll be 2 Lib (Desktop/Device).
I used the MediaPlayer API and apparently there's also this function on coredll so maybe it'll works...
I'll do it tonight or tomorow cause I've no time for the moment sorry...
