It should be obvious that you are using some conflicting resouces (not just
interrupts).
So, make sure the sound card is not automatically configured. and Reboot..
With out the
sound card configured, goto to the proc directory, and print out the files:
    interrupts
    ioports
    dma
These files report resources that are currently in use.  Then adjust your
sound card isapnp configuration around existing resource.   Make a test run,
(which may fail still on dma). If it
fails adjust one parameter at a time (usually the flaky ones first {dma,
ioports, interrupts}.

Once you have it working, write it down! in a hardcopy log file, dated.  A
simple paper
date/problem/solution logbook can solve many problems after an upgrade.  The
procedures
(failed and suscessful) that you used to find a solution should also be
logged. It may
help you analysis similar problems.

Now for the last bit of news.  My SB16 clone never worked correctly with my
NE2000
clone (the ioport conflicts couldn't be resloved).  I finally bought a PCI
ethernet card.  The
PCI card had much large resources range then the ISA card did.

Good luck,
