Adjusted default choice of audio driver. If a driver can definitely see available devices, it is chosen. Otherwise, we'll take the first driver that initializes but saw no devices...this might be because it can't enumerate them, or there really aren't any available. This prevents the dsp driver from hogging control when there are no /dev/dsp* nodes (for example, on a Linux box with ALSA and no OSS emulation).

.PP
\fBSDL_JoyHatEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used when an event of type \fBSDL_JOYHATMOTION\fP is reported\&.
.PP
A \fBSDL_JOYHATMOTION\fP event occurs when ever a user moves a hat on the joystick\&. The field \fBwhich\fR is the index of the joystick that reported the event and \fBhat\fR is the index of the hat (for a more detailed exlaination see the \fIJoystick section\fR)\&. \fBvalue\fR is the current position of the hat\&. It is a logically OR\&'d combination of the following values (whose meanings should be pretty obvious:) :
.IP "" 10
\fBSDL_HAT_CENTERED\fP
.IP "" 10
\fBSDL_HAT_UP\fP
.IP "" 10
\fBSDL_HAT_RIGHT\fP

\fBSDL_HAT_DOWN\fP
