Brad,

I've attached the unified diff to this message.

In regards to my new issue, it appears that the SEID is not released, and i=
s
reported as (InUse) in the hci dump (
http://hpc-external.jcu.edu.au/~nigel/uploads/Main/inuseHCIDump.txt). Even
though 'hcitool con' reports no connections. However, this problem goes awa=
y
if I reenable the code block at around a2play.c:1081 which is commened to b=
e
disabled because of problems it causes for the iTech headsets.

Many thanks

Nigel
