Hm... I found this somewhere near line 920 in opl3sa2.c. I am not a kernel
hacker and this is first time I took a look into a kernel source code but
this first "if" statement is not looking right to me. The initialization of
the cfg[card] struct is what I need to be executed, but it is never executed
because the variable "io" is never -1. I have removed the io == -1 condition
from the first if-statement and now the driver is working. But it's still not
the same quality as the one in kernel 2.2.17: I have no access to the mixer
settings "bass" and "treble". But better than nothing and better than the
8Bit-Soundblaster emulation. I hope this is working better in the next
release.

if(!isapnp && io == -1 ) {
if(io == -1 || irq == -1 || dma == -1 ||
dma2 == -1 || mss_io == -1) {
printk(KERN_ERR
"opl3sa2: io, mss_io, irq, dma, [...]
return -EINVAL;
}

cfg[card].io_base = io;
cfg[card].irq = 0;
cfg[card].dma = -1;
cfg[card].dma2 = -1;
[....]
