The reason for using a separate card for output when using the Delta44
for input is that the output speed would otherwise be 96kHz. Linrad is not
written for that..........
Most soundcards allow different speeds for input and output and then
you need only one card if you do not have a cross yagi. Using two
cards simultaneously for input is not supported by linrad. There are
difficult synchronization problems that should be handeled by a device
driver that drives both cards.

You can download from the Linrad home page:)
