I recently got an external sound card, and after i installed it, some strange things started to happen, ubuntu dapper, and xp wouldnt load for me, and after a whole format and re-install and a bios flash i narrowed it down to IRQ problems, i think!.
After i re-installed i got the same problems, xp took about 15 minutes to load and gnome wouldnt load at all, until a "killall -9 esd" command, so then i looked into it and i noticed the onboard sound card (SiS SI7012) has 'IRQ 177' this cant be right can it? If i look into dmesg aswell i get errors about IRQ 177, with sound device errors and it says its ignoring them.
Heres a copy.

So is there anyway to change the IRQ of this in ubuntu, from the looks of it when the external sound card was found the on board sound card was given a low level IRQ number.
Any ideas?! Im lost at this stage!
