Modules are the way to go. Compiling in-kernel is really only needed if you 
need some option that isn't available as a sysctl or if you need a device for 
which there is no module.

An onboard chip, my guess would be snd_ich (Intel and others). 
Yours may be of the "some more audio controllers embedded in a chipset" 
category and may not be supported at all or half... You may want to ask

pciconf -lv
No port needed.

If you find out which snd_blah you need and it still panics if you kldload 
that one, you should send a PR about it.
