 I am in doubt as to how the rtirq configuration

particular the entries:
RTIRQ_NAME_LIST=
RTIRQ_NON_THREADED=

 Hi,
 it depends, just "usb" might not be enough, you might make the used usb
 port head of the list. Those are the settings I'm using:
 $ grep -eNAME_LIST -eNON_THREADED -eHIGH_LIST /etc/rtirq.conf | grep -v
 \# RTIRQ_NAME_LIST="usb snd_hdsp snd_ice1"
 RTIRQ_NON_THREADED="rtc snd" 
Hi Ralf
Thank you for the advices, and sorry for the delay in replying.
Having:
~~~
$ cat /proc/asound/modules
 0 snd_usb_audio
~~~
~~~
$ cat /proc/interrupts
           CPU0       CPU1       CPU2       CPU3

 23:      15168      19473     344933      10188   IO-APIC  23-fasteoi
ehci_hcd:usb1
...
~~~
(where is my external USB2 DAC attached)
I am using:
RTIRQ_NAME_LIST="rtc ehci_hcd snd_usb i8042"
which seems to be working.
