Hi all,
I have been using FBSD since mid 2005 without any problems.
Recently, I installed 8.2R from DVD on my new machine.
(HP Pavilion p6276l Home PC)
FBSD 8.2R does not probe my sound card.

I check sound card properties with Win7 (on another partition/slice).
It says ``High Definition Audio Device'' and nothing else.
So I try again.

Both cases the speakers are still quiet.
Anyone who has a clue or experieces this problem, please point me out.
It looks like your card is getting probed in both cases, unless you have
an additional device that is not being listed. The pcm0 device above
looks to be from onboard sound on your nvidia motherboard, while the
pcm1 device is the HDMI audio output on your graphics card. My only
suggestion here is to play with the sysctl hw.snd.default_unit:
$ sysctl -d hw.snd.default_unit
hw.snd.default_unit: default sound device
It defaults to 0, try 1-5 and see if there is any improvement, as you
have multiple sound output devices.
What programs are you using to test the sound output?
