Are you sure about your assumptions? I also have a SB Live, and it never gets assigned IRQ 5 and it nevertheless works.

Usually the BIOS assigns IRQ 3, 10 or 11 to my SB Live. What's important however, is that the "emulated" IRQ ( 5 or 7 ) is "free" and not used by another device.

Here's my current setting in ctsyn.ini:

MPUPort=330
SBPort=220
SBIRQ=7
SBDMALO=1
SBDMAHI=5
OPLPort=388
SBEnable=true
JOYEnable=FALSE
JOYPort=200
Waveset=C:\SBLIVE\default.ecw
PCIPort=EF00
PCIIRQ=3

As you can see, the card currently gets IRQ 3, and it emulates a SB at IRQ 7.
