Probably not related to your problem, but I am doing something similar
(using one card for midi and the other for sound) and found that for
stable sound I had to move the cards around in the MB slots till the card
I was using for audio had a higher interrupt than the card I was using for
midi. That is my D66 is irq 21 and my ensoniq irq 20. (irq 23 -first
service- is hard wired to usb 2, and the slot that would get irq 22 still
has the case knockout in frount of it)

/etc/modprobe.d/alsa-base.conf can be changed to force your TerraTec
driver to load after your RME driver. I put a line like:
options snd-ens1370 index=-2
in mine so my D66 is always card 0

Next, I have made sure that PA has the ensoniq turned off.
Next, best to unload PA-jack bridging. This can be done on the fly like this:
pactl unloadmodule `pactl list short modules |grep jackdbus |sed
The easiest way to reload the modules is: pulseaudio --kill.

The _only_ Use I can think of to use PA-jack bridging is to record a phone
conversation where the phone software requires PA (Skype?). So if you
never expect to do that, maybe unistall the jacksink package. The package
name is actually: pulseaudio-module-jack

Can't think of anything else right now.
