That doesn't look right. I am not sure that changing this would fix your 
problem, but I prefer to have a different RTPRIO for anything above 50.
Mine looks like:

~$ /etc/init.d/rtirq status

   PID CLS RTPRIO  NI PRI %CPU STAT COMMAND
   524 FF      90   - 130  0.8 S    irq/17-snd_ice1
   515 FF      85   - 125  0.0 S    irq/19-snd_ens1
   525 FF      80   - 120  0.8 S    irq/46-snd_hda_
    47 FF      50   -  90  0.0 S    irq/9-acpi
    75 FF      50   -  90  0.0 S    irq/20-ehci_hcd
    76 FF      50   -  90  0.0 S    irq/23-ehci_hcd
    77 FF      50   -  90  0.0 S    irq/41-xhci_hcd
    79 FF      50   -  90  0.2 S    irq/12-i8042
    80 FF      50   -  90  0.0 S    irq/1-i8042
    82 FF      50   -  90  0.0 S    irq/8-rtc0

(Yes three sound cards for testing)
the line in /etc/default/rtirq looks like:
RTIRQ_NAME_LIST="snd_ice1712 snd_ens snd eth0"

eth0 does not show because it has not been loaded before this script has 
run on startup. It would be 75 if I rerun the script.

Note I am not saying mine is right, but it seems to me I was told rtc0 
does not have to right at the top. It hasn't caused me trouble, but I do 
very little MIDI work.
