I recently installed FreeBSD 8.0 (amd64) on my laptop (HP 8510w) and most
things are working. However, a minor annoyance is that I only get sound if I
manually load snd_hda via:
# kldload snd_hda
i.e., after booting. If I place the following in /boot/loader.conf
snd_hda_load="YES"
I get no sound, even though the driver seems to load and cat /dev/sndstat
gives

Googling, I found this page:
http://lists.freebsd.org/pipermail/freebsd-bugs/2009-June/035677.html
Which reports precisely the behaviour I am experiencing. No fix or workaround
is suggested.
Has anyone with similar hardware managed to get this driver working? Any
workarounds to my problem? My audio hardware is...
$pciconf -lv
<stuff omitted>
hd...@pci0:0:27:0: class=0x040300 card=0x30c5103c chip=0x284b8086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel audio controller embedded with the 82801H chipset (
ICH8 chipset ) (82801H)'
class = multimedia
subclass = HDA
And I am using
$ uname -a

Many thanks

I had the same problem. Unfortunately, I am not at home to look at the
exact solution but I know it involves setting the sound channel in
sysctl.conf I think if you look in some of the relevant man apges, it
might give you a hint. something like snd.channel = 1 or something
similar. When I get home I will try and post the solution.
