irq 7 and sound module

[Robin Gerard <robin.jag@free.fr>]

 Hello,
 I have installed the sound module with modconf.
 My CD works fine but during the installation
 of the module I get the message : IRQ conflict.
 When I launch "startx gnome-session" the sound
 is stange.
 I see that the IRQ of soundblaster is set at 7,
 but 7 is already assigned whereas the IRQ 5
 is free on my machine.
 My question is: is it possible to change the IRQ of
 soundblaster from 7 to 5 now and how to realize
 it, without breaking my system ?
 
 Thanks in advance for ideas.
