/etc/init.d/rtirq status

If you think it is a problem with systemd, try
sudo /etc/init.d/rtirq restart
/etc/init.d/rtirq status

and see if that changes anything. If it does, systemd is running rtirq too 
soon before the card driver is running. Maybe get rc.local to run it again 
with a delay in front (sleep 10 or something).

Also check (with cat /proc/interrupts) if your Audio card still shows up 
as snd-something. If not change the "RTIRQ_NAME_LIST=" in 
/etc/default/rtirq to use whatever does show up... or if not it is 
possible to use irq/17 in that line if you know which irq it uses and it 
has it's own irq (it should, change the slot it is in if not) In any case, 
I have found using just snd in "RTIRQ_NAME_LIST=" generally puts the 
internal audio ahead of the card. I always use the full driver name or at 
least enough to be unique. ("snd_ice snd_ens enp3s0" is my line)
