It indeed helped Alain. Thanks a lot. First I recompiled my kernel as I
had compiled it to load snd_via8233(Was that necessary?). I then copied
sound.ko and snd_hda.ko to /boot/kernel and edited /boot/loader.conf to
load snd_hda at boot-time.

cat /dev/sndstat now shows,
FreeBSD Audio Driver (newpcm: 64bit 2007100200/i386)
Installed devices:
pcm0: <VIA VT8251/8237A High Definition Audio Controller> at memory
0xfbefc000 irq 17 kld snd_hda [20070930_0048] [MPSAFE] (1p:1v/1r:1v
channels duplex default)

The problem has been solved. Thanks again Alain.

Thanks to Erik for pointing me to a silly but major mistake- the
chipset being VT8237A and not VT8233A. Thanks also for landing me at
Ch.23. But I guess I need sometime to digest the information given
there.

Thanks also to Dominique for interest shown in solving my problem. Hope
the solution benifits him too.
