Bug#461735: twinkle: freezes when using a bluetooth headset both ways

[Stuart Pook]

are you using the Bluez audio service? If so please read 
http://www.mail-archive.com/ekiga-list@gnome.org/msg03135.html which 
explains that you should rather use the old plugz interface.  I 
installed bluetooth-alsa and run headsetd with the code at the end of 
this message in ~/.asoundrc.  I can then use twinkle 1.1 with my Jabra 
bluetooth headset. The sound is ok.  About every 5 or 6 connections the 
person at the other end only hears white noise and after about 30 odd 
connections everything blocks and I have to unplug and replug my USB 
Cambridge Silicon Radio, Ltd Bluetooth Dongle (0a12:0001) to make things 
work again. Please let me know how you get on.

most of the
