Hi
I run xubuntu on a IBM T41 laptop with Pentium M 1.6 and 1G ram.
Reading this (http://tapas.affenbande.org/?page_id=40) suggests that I
should have change the priority of my sound card. Here's my
/proc/interrupts:
atte@ajstrup:~$ cat /proc/interrupts

So I have two soundcards, the onboard (82801DBDBL/DBM, from looking at
lspci) and an Edirol USB UA1A. It seems that alot of stuff is sharing
IRQ 11 (soundcard, usb, graphics card, ethernet, wlan and pcmcia). So my
questions is:
Would the way to go be to reassign usb and soundcard to their own
(shared?) IRQ?. How is this done and which IRQ should I go for?
