So my questions: > At present, on-board CS4231A audio controllers on SBus/EBus are supported. Other PCI audio controllers may work unless it has DMA address space limits. Due to the high location of DVMA address, sparc64 requires 32bit DMA capable H/W. And most cheap PCI audio cards does not support full 32bit DMA address space. :-( Quick looking the es137x source, it indicates it has no DMA address limitation. So I guess it will work if you build snd_es137x.ko module. #cd /usr/src/sys/modules/sound/driver/es137x #make #kldload ./snd_es137x.ko > Is there working support for pci audio cards under sparc64?

Live! and Trident 4D Wave PCI does not work due to the limit of DMA address space. -- Regards, Pyun YongHyeon http://www.kr.freebsd.org/~yongari | yongari@freebsd.org
