Hi I have reimplemented bthset to use pad instead of the btsco(4) audio driver 
(stll not ready for submission). However it is impractical with the current pad 
as I need it to support recording (full duplex) poll and to be able to be set 
non blocking.  So I have patched pad and padvol to support these.
Try to record with pad:
audiorecord -d /dev/'pad audio device' test.snd
I will post the patches in a subsequent email as I'm using the web based sendpr.
