Yes, run pavucontrol, select the last tab (configuration?) select the card
you want PA to leave alone and turn it's "profile" to OFF. Counter
intuitively, I turn off the cards Jack is not going to want to use as I
have found that the PA-jack bridge links the two cards. In other words, if
PA uses the internal HDA (mine does not do good low latency due to HW
problems) and Jack is using my USB IF, the problems I would have with the
HDA, show up on the USB. The PA-Jack bridge forces PA to try to do the
same latency as jack.
I am not sure if that is clear. The thing to remember is that they do
interact when bridged. This is not really a bug any more than the fact
that a trailer will affect the way your car drives.
