I found the first half of my solution,
It's possible to play it with MediaPlayer
however the MCI extension was not registered in the registry.

So First register the m4a extension as MPEGVideo under

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI
Extensions

Second,
Use the following code in BCB

MediaPlayer1->FileName = OpenDialog1->FileName;
MediaPlayer1->DeviceType = dtAutoSelect;
MediaPlayer1->Open();
MediaPlayer1->Play();

Hope it can help someone around the corner.
