--- Comment #11 from Jörg Höhle hoehle@users.sourceforge.net 2010-08-13 09:33:42 --- To try and express myself clearer: open cdaudio<N> is strictly equivalent to open MCI_DEVTYPE_CDAUDIO|N<<16 Since the system.ini (undoubtfully IMHO) tells what .dll/drv is attached with CDAUDIO<N>, that's the driver to load. The driver does not care whether it was installed as CDAUDIO1 or CDAUDIO2 on a particular system, nor does it need or receive any extra parameters.
