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.

Regards
