[LAU] rtirq questions

Hi list,

https://www.rncbc.org/drupal/user/register did not load, so I hope it's
okay to ask here.

Performance of my audio system somehow degraded so I tried to find the
culprit.

/etc/default/rtirq looks liks this:

# IRQ thread service names
# (space separated list, from higher to lower priority).
RTIRQ_NAME_LIST="snd usb i8042"

# Highest priority.
RTIRQ_PRIO_HIGH=90

# Priority decrease step.
RTIRQ_PRIO_DECR=5

# Lowest priority.
RTIRQ_PRIO_LOW=51

# Whether to reset all IRQ threads to SCHED_OTHER.
RTIRQ_RESET_ALL=0

# On kernel configurations that support it,
# which services should be NOT threaded
# (space separated list).
RTIRQ_NON_THREADED="rtc snd"

but even so,

$ /etc/init.d/rtirq status

   PID CLS RTPRIO NI PRI %CPU STAT COMMAND
   595 FF 50 - 90 0.0 S irq/34-mei_me
   634 FF 50 - 90 0.0 S irq/36-iwlwifi
   730 FF 50 - 90 0.0 S irq/39-rmi4_smb
  1619 FF 50 - 90 2.9 S irq/35-nvidia

    48 TS - 0 19 0.0 S ksoftirqd/6
    54 TS - 0 19 0.0 S ksoftirqd/7

I was expecting to see snd and usb on this list or am I mistaken?
