Also here is output from /dev/sndstat:

FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <HDA Analog Devices AD1986A PCM #0 Analog> at cad 0 nid 1 on hdac0 
kld snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex default)
pcm1: <HDA Analog Devices AD1986A PCM #1 Digital> at cad 0 nid 1 on 
hdac0 kld snd_hda [MPSAFE] (1p:1v/0r:0v channels)
