I thought yours works flawlessly?

I can't tell. The origin of the problem is probably somewhere else :(
. Perhaps output of the crashdump and backtrace would help us to
investigate the issue.

Please update to the latest -current since snd_hda is already part of
the -current build process. Besides, read /usr/src/UPDATING for latest
breaking news.

By the way, please fetch http://people.freebsd.org/~ariff/test/hdac.c
and put it into sys/dev/sound/pci/hda/ , rebuild, etc. Stay in plain
console (no X) while try to play something, perhaps using
mpg123/mplayer etc. Few people reported simmilar issue which cannot
be reproduced after staying out of X/KDE while abusing sound playback
through plain console.
