Hello Joep,
The cards you mention are fairly old, their modern counterparts are more

affordable and cheaper in shops like Feedback (or Thomann if you prefer

buying on the internet).

The onboard card should work properly with those JACK settings. Maybe it

helps to disable CPU frequency scaling (the ondemand service) or to set

it to 'Performance" with the help of the CPU Frequency Scaling panel

applet for Gnome (assuming you're using Gnome).
Groet,
Jeremy
