I don't know BT, but you can specify which usb soundcard should get
which card index using the module options vid and pid like:

options snd-usb-audio index=1,2 vid=0x0ccd,0x0763 pid=0x0028,0x0117

This will make the usb device with Vendor ID 0ccd and Product ID 0028
always be card index 1, and the device with vid 0763 and pid 0117 be
at card index 2. You get the numbers with lsusb.

In this example it would also be possible to omit either vid or pid,
but if you want to use USB soundcards by the same vendor that share
the same vid, this options line will circumvent possible name clashes.

Ciao
