Yes, these are ISA sound cards, so they must have CONFIG_ISA and CONFIG_ISA_DMA. Although CONFIG_SND_SB8_DSP, CONFIG_SND_SB16_DSP and CONFIG_SND_WSS_LIB have no direct dependency, but the drivers selecting these are all in "if SND_ISA" in sound/isa/Kconfig. > or should only pieces of each driver depend on ISA_DMA_API ? I wonder which configuration makes it possible. Did you see a similar problem with randconfig? thanks, Takashi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
