You probably have a plug and pray sound card.
When you build a new kernel you need to reactivate the PnP configuration
by booting with "-c" and setting the pnp options for your card.
You'll need the following in your kernel for this to work:
options USERCONFIG # Boot -c editor
controller pnp0 # Enable PnP support in the kernel
These changes are then stored in the kernel (after successfull boot [as
this is done in /etc/rc with "dset -q"]) so that you dont need to redo it
on subsequent boots.
I got annoyed by this and created a /kernel.config file to do it on every
boot so I didn't have to bother when I built a new kernel.
You will also need the following option in your kernel for this to work:
options USERCONFIG_BOOT # Imply -c and parse info area
Note that if /kernel.config doesn't exist it wont boot without you
choosing an option from the menu that comes up... so you probably want
to copy /kernel.config to /kernel.old.config so you can boot /kernel.old
too without seeing this menu.
Also note that your kernel will be written to on every boot!!
This may not be what you want as there may be a greater chance of loosing
your kernel.
Here's my /kernel.config (for a Creative Labs PnP Sound Blaster 16 with a
Vibra16C chip):
localhost: {17} cat /kernel.config
USERCONFIG
pnp 1 0 os enable irq0 5 drq0 1 drq1 5 port0 0x220 port1 0x330 port2 0x388
quit
localhost: {18}
I'm guess that you were able to boot the other time as you may have just
booted another OS (Win95 ?) which has activated the card ?? - does your
machine have FreeBSD and another OS on it ?

"If it is true that our Universe has a zero net value for all conserved
quantities, then it may simply be a fluctuation of the vacuum of some
larger space in which our Universe is imbedded. In answer to the
question of why it happened, I offer the modest proposal that our
Universe is simply one of those things which happen from time to time."
E. P. Tryon from "Nature" Vol.246 Dec.14, 1973
