I have an ISA sound blaster card here..
Not sure why, the Apple docs (
http://docs.info.apple.com/article.html?artnum=72406) specifically suggest that you should ENABLE plug-n-play on your ISA/EISA driver in Configure.app
The only way I could get my Sound Blaster card to be recognized and working was to disable plug-n-play:
