The driver supports on board cs4231 which is found on SBus/EBus Ultrasparcs. I'm still finding a way to workaround DMA address issues on some poorly-designed(for Sound Blaster compatibility?) PCI audio cards. In theory, all PCI audio cards should work on sparc64 but simple experimentation showed there are much more complicated things. For instance ESS Solo-1 works well if we use only playback due to its DMA address limitations.(capturing is not possible for the card on sparc64) Other PCI audio cards(e.g. Trident 4D-Wave) that have DMA address limitation may not work at all. At present I have no idea how to handle all these cases correctly. Cheers, Pyun YongHyeon -- Pyun YongHyeon <http://www.kr.freebsd.org/~yongari>;
