snd_hda sound driver bug?

[eric baumbach]

Hello,

I was excited to see that with FreeBSD 7.0R my sound card should work
natively under FreeBSD.  My chipset was listed in the man pages to be
reported working ok.  (nVidia MCP51/Analog Devices AD1986A).

I added the sound driver to /boot/loader.conf; snd_hda_load="YES"

My sound card will still not work.  I have tried sending data files to
/dev/dsp, playing audio cds and playing some X games all with no sound.

The free OSS driver from ports does work, though not very good.

I found a potential
bug listed in the man pages as well for the snd_hda driver:

"A few Hardware/OEM vendors tend to screw up BIOS settings, thus rendering
the snd_hda driver useless, which usually results in a state where the
snd_hda driver seems to attach and work, but without any sound."

The BIOS I am using is AMI.

I am running FreeBSD 7.0R on an ASUS A8M laptop with a stock kernel.

Here is my current dmesg:

Is there any possible workarounds I can try to keep testing my card and get
the sound to work with this driver?

Many Thanks
