Thanks for the info, I edited /etc/modules and /etc/modutils/sb along with
/etc/isapnp.conf and could not get my sound card initialized.

Here's a clip from dmesg:

Soundblaster audio driver Copyright (C) by Hannu Savolainen 1993-1996
SB 4.16 detected OK (220)
sb: Interrupt test on IRQ7 failed - Probable IRQ conflict

At first I thought that my sound card was fighting over my winmodems IRQ, so I
removed the winmodem from my computer. I later received the same error message at
boot time.

Here a clip from cat /proc/interrupts

As you can see the soundblaster card has attached itself to IRQ 7 (its a PnP
card). This should be no problem since I have mostly PCI hardware (besides the
soundcard) and I'm running PnP BIOS. Is there any way I can auto-detect my sound
card's hardware settings so that I can use those options for the sb module?
