If you have access to archives of this list. That's a good place to start.
My son and I struggled through several systems, they were all different so
I do not think there is a set formula. In general:
1) If windows is also installed on your system see what it uses for irq,
memory ports etc. Our technique has been to match that in FreeBSD.
2) Check out the handbook and see if it addresses your card.
3) A lot of the comments in this list say *do not* use PNP. Note if you
take it our of the kernel you must (should?) also disable it for the
card in the BIOS.
4) make sure to run /dev/MAKEDEV
That said here is what we did:
a) Dell 7500 Inspiron: One line in the kernel config.
device pcm
b) Dell PE 300
This system had all sorts of problems, none coming from FreeBSD. The
PE 300 has video card on the motherboard and no sound card. In
configuring this for a workstation we added a better video card and a
Sound Blaster 16 that we cobbled from an older system. That involved
forcing the BIOS to use thesame irq for the video and sound cards
that win98 used. So in the kernel config there we added:
device sbc0 at isa? port 0x220 irq 5 drq 1 flags 0x15
device pcm
Again we choose the irq and port to match what windows assigned.
After reconfiguring the kernel and building the devices, you should have
things like audio, sndstat, mixer, .... On the 7500 they all have a
primary device number of 30 so:
mneme:/dev> ls -l | grep "30,"
crw-rw-rw- 1 root wheel 30, 4 Oct 13 02:32 audio0
crw-rw-rw- 1 root wheel 30, 3 Oct 13 20:19 dsp0
crw-rw-rw- 1 root wheel 30, 5 Oct 13 02:32 dspW0
crw-rw-rw- 1 root wheel 30, 2 Oct 13 02:32 midi0
crw-rw-rw- 1 root wheel 30, 0 Oct 13 02:32 mixer0
crw-rw-rw- 1 root wheel 30, 8 Oct 13 02:32 music0
crw-rw-rw- 1 root wheel 30, 9 Oct 13 02:32 pss0
crw-rw-rw- 1 root wheel 30, 1 Oct 13 02:32 sequencer0
crw-rw-rw- 1 root wheel 30, 6 Oct 13 02:32 sndstat
You can tell if the setup is okay (as opposed to any applications)
by
cat /kernel > /dev/dsp0
Make sure the sound is turned down first, or choose a smaller file. If all
that works you can then tackle which application you want to use. Chris
settled on xmms which works fine for us.
