[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 10 TS - 0 19 0.0 S ksoftirqd/0 18 TS - 0 19 0.0 S ksoftirqd/1 24 TS - 0 19 0.0 S ksoftirqd/2 30 TS - 0 19 0.0 S ksoftirqd/3 36 TS - 0 19 0.0 S ksoftirqd/4 42 TS - 0 19 0.0 S ksoftirqd/5 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? m.
