Hello, I previously reported a problem loading the snd-interwave module from alsa-driver-1.0.0pre3 into linux-2.2.25.
I found a fix, but not the complete answer, because I'm not yet clear about the different roles of the support/isapnp and support/pnp code. The problem is that support/pnp/pnp.c refers to functions in the support/isapnp code so it #includes isapnp.h without CONFIG_ISAPNP being defined. The result is that dummy isapnp functions defined in isapnp.h to do nothing are used, instead of the working functions in the snd-isapnp module. See support/isapnp/isapnp.h around lines 308-376. As a temporary fix I simply defined CONFIG_ISAPNP at line 308, but this will not suit everyone else's configurations. I suspect that CONFIG_ISAPNP should be defined in the files under support/pnp when they need to link with support/isapnp code, before isapnp.h is include in them, rather the way I have hacked it.
