I have a ESS1868 in my Laptop + Stationary Compaq Deskpro. When I use SB Pro emulation mode it will only manage 22 kHz/Stereo/8bit. It works but not with full quality. So I tried the pcm0 driver but it will not work, it only plays the first buffer-2-dma transfer size. I have checked that the driver really get it's irq when the dma is complete. And the dma channel is also checked with help of the laptop's manual. But if I change the function 'dsp_wrintr()' in /usr/src/sys/i386/isa/snd/dmabuf.c (fbsd ver=2.2.7-R) And let it set 'b->dl = 0;' it will at least not just stop. But play some very noisy(tm) sound. But I can still recognise the sound. Maybe someone have fixed this ..? (I can't easily just plug in another card in this case.. unfortunly) Btw, I have the PDF file documentation for the ESS 1868 chipset. /Peter Email: pb@NOSPAMwave.campus.luth.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
