Since I upgraded to FreeBSD 8.0-BETA2 amd64 my sound device doesn't work
In my /boot/loader.conf I have got 

# kldstat shows 
        Id Refs Address            Size     Name
        1   35 0xffffffff80100000 ce46e0   kernel

# cat /dev/sndstat
        FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
        Installed devices:
        pcm0: <USB audio> at ? kld snd_uaudio [MPSAFE] (1p:1v/1r:1v     
        channels duplex default)

A device /dev/dsp0.1 exists.

(Mailing lists couldn't help.)

Please tell me, if you need more information.
