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
