Audio problem in FreeBSD 6.2

Hi,
I'm not able to enable sound on my FreeBSD 6.2. The error message when I click on the speaker icon is:
[HTML]The volume control did not find any elements and/or devices to control. This means either that you don'thave the right GStreamer plugins installed, or that you don't have a sound card configured.[/HTML]
My motherboard is Asus K8V-VM with southbridge VT8233A. I tried,

kldload snd_via8233

When it didnot work I tried,

kldload snd_driver

cat /dev/sndstat yields just,
[HTML]
#cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices
[/HTML]
The motherboard uses Realtek ALC660 driver I believe...

Any idea how I can solve this problem?

Hi all,

The problem is solved.

The actual chipset was not VT8233A but VT8237A. Also, I was informed that VT8237 and VT8237A are not the same. Thats the reason why 'kldload snd_via8233' was not able to solve the issue.

The actual driver needed was 'snd_hda'. I got the precompiled module from http://people.freebsd.org/~ariff/lowlatency.

It was also said that this module was not currently available in FreeBSD -RELEASE and would be available if we upgrade to FreeBSD -STABLE.

Hope this thread may help somebody.

Regards,
SV
