This is FreeBSD 2.2.6. When I first built a kernel to support this card I enabled the PnP controller, but it could not find (or recognize) the card. After searching the documentation I found the chipset. :) I'm not knowledgeable about sound cards, so I'll just quote the docs: "Crystal Semiconductor CS4232, Yamaha OPL3 (YMF262), and Yamaha D/A converter (YAC512) compabible with Windows Sound System and Soundblaster Pro". OK then, I configured with the flags set at 0x11 and I got the same result faster than when the flags were set at 0x0. However, things were stable with the flags set at 0x13 for an hour or so but eventually this failed too with the same error message. I did not include an additional error message in my first note so here it is: /kernel :timeoute flushing dbuf_out.chan cnt 0xff00 flags 0x000002c1 Also, I cannot seem to transmit audio using vat with this card configuration and the input volume control doesn't affect anything. Is it the card or is it vat? One more thing - the volume level from this card is very low, I used xmix to up the dsp level to the max and turned the volume of my speakers way up to get an acceptable volume.
