My line from pciconf is pcm0@pci0:2:7: class=0x040100 card=0x030013f6 chip=0x70121039 rev=0xa0 hdr=0x00 It knows mine is pcm0 and we have a different card number.

You have to go through the kernel modules and find which sound module handles the SiS7012. That is where the maintainer comes in and I don't have any idea who that is right now. I have never looked at the sound stuff. It has been a sort of black magic that worked. I also have a -current machine that won't do the installworld and it has my attention right now :(. If you do a find from /usr/src. For the lack of a better idea, I just used sound. You will see something like # find . -name sound -print ./sys/compile/TOPAZ/modules/usr/src/sys/modules/sound ./sys/dev/sound ./sys/gnu/dev/sound ./sys/gnu/i386/isa/sound ./sys/i386/isa/sound ./sys/modules/sound Your problem is buried in there somewhere. I think you can ignore the ../gun and ../isa. TOPAZ is the name of my kernel and the kernel config moved the code that handled SiS7012 in there. TOPAZ/.../sound has 3 directories, driver, pcm, and snd. I assume that your 7012 handling code that doesn't recognize your module will probably show up in one of them. You can use http://www.freebsd.org/cgi/cvsweb.cgi/ to track who did the last work on the module with the SiS7012 in it. They will be your best bet on getting sound. I don't what sound cards run where you live but I can buy really cheap pci ones "that work" for under $20 USD. They are usually as good as the integrated ones if not better. It all depends on the import duty and how long you can deal with a computer and no sound :). Kent -- Kent Stewart Richland, WA http://users.owt.com/kstewart/index.html
