does bluetooth audio gateway conflic with audio codec(sound card) on board?

hi, experts,

(WinCE 5.0, samsung arm920t cpu.)

There was already one audio codec chip on my board ,that had been driven
as *WAV0*.
i socket another BlueTooth USB Adapter,for communicate with my BlueTooth
HeadSet.this
BlueTooth Adapter been driven as *WAV1*,(bthscosnd.dll),and then i use below
command
to find & rounte audio stream & connect the HeadSet.as below,

btagconfig -audio on

i get,
"Opening Bluetooth audio..."
"Operation successful."
but, nothing happen.

----------------------------------------
after remove *WAV0*,then reset,of couse,this time, WAV1 -> WAV0.
i can hear all sound ,even system event sound,from HeadSet.

does they conflic?how to use them both?

waveOutOpen(&ho, 0,....) is ok,and i can hear all sound
from audio codec on board, but waveOutOpen(, 1, ...) always return
failed,and said no that device.

i found the answer after i reading the source code!

the answer is the Audio GateWay(btagsvc.dll) rounte the stream to device 0
always!

waveOutMessage(0, WODM_BT_SCO_AUDIO_CONTROL, 0, TRUE);

the first parameter is *0*. that means BT HeadSet MUST be waveform device 0
when using
this Audio Gateway.but default,the BT HeadSet always be device 1. Why?

the other importent thing

i used to think device0 map to WAV0,device 1 map to WAV1 ,as below
device 0 --- WAV0
device 1 --- WAV1
but it is wrong.device 0 means the first loaded device by device.exe.
(*order* in register decided the device index,not *Index* in register.)

so, i edit their order value,this time ,BT -- device0, audio chip --
device1.
everything is ok!thank gods!
