creative sb live 24 bit ext no audio in conjunction with internal intel audio card

[fabienne s]

hello,

i'm having issues with running multiple audio cards in freebsd5.4 
stable: (running on a fujitsu p7010d)

internal intel audio card works perfectly with snd_ich, external is 
creative sb live 24 ext with device sound, device "snd_emu10k1", and 
device "snd_uaudio" in the kernel.

cat /dev/sndstat gives:
pcm0: <Intel ICH4 (82801DB)> at io 0x1800, 0x2080 irq 11 bufsz 16384 kld 
snd_ich (1p/1r/0v channels duplex default)
pcm1: <USB Audio> at addr ? (mixer only)

dmesg | grep pcm gives:
pcm0: <Intel ICH4 (82801DB)> port 0x2080-0x20bf, 0x1800-0x18ff mem 
0xd0100800-0x01008ff, 0xd0100c00-0xd0100dff irq 11 at device 31.5 on pci0
pcm0: <Unknown AC97 Codec (id = 0x414c4770)>
pcm1: <USB Audio> on uaudio0
pcm1: chn_init (pcm1:play:0) failed: err = 19
pcm1: pcm_chn_create(ua_chan, 1, 0xc48f3080) failed

dmesg | grep uaudio gives:
uaudio0: Creative Technology SB Live! 24-bit External, rev 1.10/1.00, addr 2
uaudio0: audio rev 1.00
pcm1: <USB Audio> on uaudio0

ls /dev/ | grep dsp gives:
dsp0.0
dsp0.1
dspW0.0
dspW0.1
dspr0.1

does it look like i'm missing dsp1.0 or something similar in /dev?  for 
what it's worth, the internal audio card works with mixer ogain and 
mplayer.  when i try:
mplayer -ao oss:/dev/dsp0.0 /usr/music/testfile.mp3
and
mplayer -ao oss:/dev/dsp0.1 /usr/music/testfile.mp3
i get audio out the internal audio card both times and no audio out the 
external device.

the creative external usb device powers up with it's blue led and when i 
plug the outputs into an amplifier, the ports are hot (gets a nice pop 
when hot plugging audio in the mini jack outports on the back and the 
headphone out on the front).  if i need a patch for uaudio or mixer how 
do i implement it?  how do i tell mixer which card to act upon?  i've 
been digging on this list and haven't seen the same non /dev/dsp 
creation problem as mine.

thanks for any and all help,
fabienne
