I've split up the info for both 4.0 and 5.0 versions. I've tested both of these, and source references are in the text. I hope this helps owners of the SB Live! cards. I'm sending these to the webmasters of http://www.defcon1.org and http://defcon1.erudition.net for posting in case anyone needs them at a later date.

Sound Card on FreeBSD 4.0</u></b></center> <p> First, I'd like to thank Luigi Rizzo and Cameron Grant for cranking out a <br>working pcm sound driver that supports the SB LIVE!, as well as Seigo <br>Tanimura for documenting their work in the pcm man page. Thanks guys! <br> Second, thanks to Martin Miskin, Walter Brameld, and Frank for spanking <br>me on the mailing lists. My first HOWTO for the SB Live should not have had any <br>parts assumed. I was running 5.0-current and assumed that the pcm driver <br>would be about the same since the 5.0 branch from 4.0 was so recent. This <br>HOWTO is strictly for FreeBSD 4.0-RELEASE (if you run -stable, YMMV) and <br>most of it was documented by Walter. I've installed 4.0-R just to <br>test the sound card to verify it works here too. Walter, thanks for the <br>input! <p>Now, on to the good stuff... <p>1) Make sure you have source files on your hard drive. Then: <p><b>cd /usr/src/sys/dev/sound/pci</b> <p>Now add a few files to our present working directory that we just changed <br>to. Fetch the two files, emu10k1.c and emu10k1.h from: <p><b>ftp://ftp.freebsd.org/pub/FreeBSD/FreeBSD-current/src/sys/dev/sound/pci/</b>; <p>2) Edit emu10k1.c. Look for the following line (somewhere around line 1163): <p><b>codec = ac97_create(dev, sc, NULL, emu_rdcd, emu_wrcd);</b> <p>Remove the NULL entry. It should now say: <p><b>codec = ac97_create(dev, sc, emu_rdcd, emu_wrcd);</b> <p>3) Place these files in /usr/src/sys/dev/sound/pci. You may also wish <br>to keep a backup so your first CVSUP doesn't flush them down the <br>toilet. <p>4) Edit /usr/src/sys/conf/files and insert the following line in the <br>appropriate place (alphabetically, around line 980): <p><b>dev/sound/pci/emu10k1.c optional pcm pci</b> <p>5) Edit your kernel config file and make sure it has the following two <br>devices: <p><b>device pcm</b> <br><b>device pci</b> <p>6) Recompile your kernel and reboot. dmesg should show the following: <p><b>pcm0: <Creative EMU10K1> port 0xe400-0xe41f irq 10 at device 9.0 on pci0</b> <br><b>pci0: <unknown card> (vendor=0x1102, dev=0x7002) at 9.1</b> <p>Cat /dev/sndstat should show: <p><b>FreeBSD Audio Driver (newpcm) Apr 7 2000 13:12:21</b> <br><b>Installed devices:</b> <br><b>pcm0: <Creative EMU10K1> at io 0xe400 irq 10 (1p/0r channels duplex)</b><b></b> <p>or something similar, io and irq may vary. <p>7) Finally, make the sound device in your /dev directory: <p><b>/dev/MAKEDEV snd0</b> <p>8) Reboot. <p>9) Start your favorite audio application. It's time to rock and roll. <p>Some people have reported "DAC not ready" errors and/or problems with the <br>AC_97 references. This HOWTO was tested on a clean ftp install of 4.0-R on <br>todays date, April 8, 2000. Good Luck with your system(s)! <p>-Christopher D.

The SB Live! cards are PCI. Make sure you have this device option in the kernel. No, I'm no wiz on this topic. I just pulled that from the first line of "man pci" to state its purpose. Now that we've got support in the kernel, we can complete rebuilding the kernel as needed.
