For the record,  using Gnome Bluetooth applet solves  my problem (like I
said in  another mail). It seems  that bonding correctly  to a bluetooth
device is  far more  complex than I  though using command  line. Despite
having used hcitool {cc,con,auth,link,key}, I did not get the files that
I get  when using  Gnome Bluetooth applet:  linkkeys, profiles,  sdp and
trusts.

Also  note that  the  error 'BT_GET_CAPABILITIES  failed :  Input/output
error(5)'  is really  misleading.  When getting  capabilities, it  first
tries to find a device and if it does not find one, it outputs the above
error. There is  nothing sent. I have not looked the  whole logic, but I
suspect that if  your remote device is not in  linkkeys and in profiles,
it will just be ignored.

I encourage  all reporters  (except Mark because  I think that  it tries
with a remote device that does not support A2DP) to check the content of
/var/lib/bluetooth and  to try  to do the  pairing with  Gnome Bluetooth
applet.

But maybe there was a but which is fixed in 4.60.

Moreover, I tried  to test my headset with  alsaplayer. alsaplayer seems
to try  to open the  device twice which  is rejected with an  error like
this:

bluetoothd[7968]: open a2dp - object=ANY source=ANY destination=00:0F:59:11:XX:XX lock=write
bluetoothd[7968]: Client already has an opened session

I have used mpg321 which does not have this problem.

I use this asoundrc:

pcm.bluetooth {
  type bluetooth
  device 00:0F:59:11:XX:XX
}

pcm.!default {
 type plug
 slave {
   pcm bluetooth
 }
}
