snd_uaudio.ko (USB audio driver) doesn't work on FreeBSD 8.0-BETA2 amd64

[Peter Ulrich Kruppa]

Hi,

since I upgraded to FreeBSD 8.0-BETA2 amd64 my sound device doesn't work
anymore. 
In my /boot/loader.conf I have got 
	snd_uaudio_load="YES"

# kldstat shows 
	Id Refs Address            Size     Name
 	1   35 0xffffffff80100000 ce46e0   kernel
 	2    1 0xffffffff80de5000 13dc0    snd_uaudio.ko
	[...]
# 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.


What's going on there?

Thanks for your replies and hints

Uli.
