AFAIK the only documentation for EMU10K1 is driver source code for Linux. And the code is full of magic constant and its microcode. It's really hard to understand internal architectures and DMA etc. Without more information from Creative it would be hard to fix/enhance current emu10k1 driver, IMHO. Of couse, Creative says they released all necessary PCM programming information for their EMU10K1 products. :-( -- Regards, Pyun YongHyeon http://www.kr.freebsd.org/~yongari | yongari@freebsd.org
