Things to check. First, are there OSS modules present trying to
grab the device resources first? If so, disable them. (ESS18xx support is
provided by OSS's 'sb' module.)

These are redundant. Remove one of them.

Next thing to check: Does the chip show up in the list output by the
command 'pnpdump'? If not, change the 'isapnp' option above to read
"isapnp=0".
The snd-es18xx driver performs a PnP scan even if you supply all the
parameters yourself. If the chip doesn't show up on the PnP bus, the driver
will fail to initialize. Supplying the option "isapnp=0" will suppress the
PnP scan, and the driver will trust your supplied values. (Note: This was
true as of ALSA 0.9.0rc6. I don't know if this has changed for rc7.)
