'System' of 'Control Panel'. Select same I/O resource as I/O
port of MPU-401 General MIDI in DOS games or applications.

duplex functions, some applications will detect the sound card
not a full-duplex one. Please make sure that the playback
device is set to "Sound System Playback" and the record device
is set to "SB16 Record" in "Multimedia" of "Control Panel",
the item "Use preferred devices only" must also be marked.
In IPhone 5.0, even when you select the playback and record
devices to different ones, still the system will detects the
card as being not full-duplex. Even so, you have to set the
devices to different ones to enable the full-duplex functions.
In fact, the full-duplex functions still work in this way.

to "Sound System Playback" in "Multimedia" of "Control Panel".
