Thanks, 'Nando!!!  You've provided great help as always

Looks like I've found the culprit (me!!)

(Gulp!!) I guess that's what I get for keeping my mail in Outlook.  It is the only practical way I can 'cut n paste' an X display.  I'll check this out further by logging into the graphics console.

Great info.  Thanks!!

More good stuff

Excellent suggestion.   Since this is currently viewed by Jack as a single 8 channel interface per card, is it practical to get multiple instances of Jack running (one per card) or is re-working the driver such that it looks like one big card a better solution? (it would only need one Jack instance, but you'd be bound by only having one set of interrupts available).   We've having to work some 'black magic' because there is no direct DMA on the card.  Best 'guestimate' would be to do what is normally done with multiple Delta 1010s that are clocked together.  Unfortunately, none of us have multiple Delta 1010s to look at.
