Have the same problem on 3.2-RELEASE X86_64_GENERIC

Looks similar (pcm0 SB600 and pcm1 NVidia) on my system now, after my

My kernel.old is not much older, but there is also a kernel,
that starts with my 3.2 world without errors, also has pcm0 and pcm1
when I kldload snd_hda, and plays sound nicely (with mplayer in my case).
