Ok, then they must have a way to route audio through the hci connection.

I don't think it's like that. I think I've seen Marcel complain about 
silicon wave not working with him on specs/drivers.

Everything is cheap these days. I saw a CSR class 1 bt1.2 usb dongle for 
us$10 shipped the other day.

yeah, I traded email with the infineon tech guy who gumstix works 
through. He danced around this question but I think it's because they 
don't have a way to do it.
