Comment 30 for bug 274950

Per the comments about audio, i've done an upload of bluez 4.9-0ubuntu1~ppa2 and alsa-lib-1.0.17a-0ubuntu4~ppa1. These will create an additional ALSA device that is usable when paired. Test it with aplay:

aplay -D headset $FILE

aplay will receive IO errors when not paired if you use this device. There are no side effects with regular usage (not headset device). When the device is paired but out of range, there will be delayed responses to the applications trying to use it as IO errors time out.
