Thank you Jeremy,
I understand this and started writing a script, but first I'll get rid
of firewire, I don't need it and then of Envy24 too, I don't need the
"MIDI devices" at the moment.

I'll add sudo rmmod snd_ice1712 and than set the latency of the RME and
other cards. Strange, in the morning I couldn't remove snd_ice1712, now
it does work, perhaps a typo.
Testing it may take some time, I've to do "weekend things", but I'll
set up latency now.

With latency timer set to 0 nothing seems to be
different, I already
hear xruns while writing this mail. lspci does confirm that the RME
card is set to latency 0, but the other cards still have higher
values, so I set PCI Latency Timer (CLK) to the max [255]. No
soundcheck, regarding to lspci it's more worse than before, so I'll
reboot now and restore the default value [64] and then write a
script as explained by http://www.mythtv.org/wiki/PCI_Latency .

Your RME card should have a high latency value and the rest should be
lower. This allows your RME card to hold on to the PCI bus for a
longer period of time (higher latency value = device can hold on to
the bus for a longer period of time).
