It is ok for configure to not find soundcard.h
That will result in that the C programs will include <sys/soundcard.h>
which should be fine if you did not install oss.

Because one wants 96kHz and 4 channels for input. If Delta44 is used
it is not suitable for output because it would run at 96kHz also and
load the CPU very much. It is better to use something else for the output,
something that runs at 6kHz or so.

The file conf.h which is generated by configure should have a line
#include <sys/soundcard.h> which should be surrounded by a valid if
statement. There should be no message about it. If soundcard.h is
not found, compile should exit immediately.

This is completely new to me. The text "OUT OF SCAN RANGE" does not originate
in Linrad. Maybe svgalib or somewhere else???

I suggest you wait with the moon initialization. Linrad should run
without it and if the problem is in svgalib or somewhere else it should
show up in normal operating mode. If you can make Linrad run properly,
reading A/D data from your soundcard, it will not be difficult to find
what the problem is with the moon initialization.
