is it true ?

It is true that the Vibra16X is NOT supported in full-duplex mode in Linux, *BSD, or OSS commercial. This is because the Vibra16X is a strange cookie and Creative Labs doesn't even appear to have documentation for this card (how the hell they wrote a windows driver I don't know - Alan had a contact in C.L. a few years ago and that guy couldn't find the needed docs). So we're SOL on that
front. I've recently recieved one of these cards from a fellow Linux user in Canada for the purpose of attempting to figure out full-duplex operation of the
card and implementing it in Linux. I am currently (with some success) reverse engineering the windows driver to figure out how it ticks. I'm keeping a journal of my progress and will post to this list when I have something worth talking about :)
