This is a general, not necessaryly FreeBSD related question. A friend of mine and I had a hard night to get two ISA soundcards running in a PC (PII/400). One card was a Terratec the other an Adlib, which has a nicer wave table. We had severe problems, to get two cards running under Win95 and NT 4.0 SP4. Both cards are Plug & Pray cards and we ask ourselves, if we got perhaps out of DMA channels. When using 2 cards together, NT doesn't boot anymore. Both cards run in full duplex mode ... So, do they need 2 or 4 DMA channels ? Well, just need some technical background, how it would be possible to drive 2 ISA soundcards in one PeeCee.
