[N6OJ]

Hi Guys
I think I asked this eons ago without any answers but here goes again.
I have 5 different audio cards in the computer,
I use 2of them Signal links, usb audio codec
and usb audio codec 2
in the receive settings they are numbers 5 and 5
in the transmit pane they are nos 3 and 4
the number 3 codec sticks
when I set the number 1 or 2 decode screen the number 5 and 5 codec 2 
will not stick
it works ok on MMTTY
any help out there ???? ??
