The interface line does not go in .asound

Make sure you have read the info file for bluez as to how to start bluetooth on a rpi.  There is more info in this thread http://forum.tinycorelinux.net/index.php/topic,24427.0.html

Hi Paul.  I do connect bluetooth.  I am using your scripts from that link to connect. My problem seems to be able to have alsa recognize the interface.

The more I look at your asound.  Do not use the mac address of the raspberry pi bluetooth adapter, you need the mac address of your bluetooth device.

I am using the pi MAC address.  The asound file is a copy before any changes.

Perhaps explain what you are trying to do.  What are all of the devices involved, and what is the audio path?

Thank you for looking into this.  I have given up on it for now.  Think a complete restart by compiling the sources may be needed.
