I've noticed this as well with the bluez 4.12 build that's currently 
included in Intrepid. My test is to output to the headset using mplayer 
and the alsa plugin. It doesn't always fail to start playing, but when 
it does fail I get the same endless delay. But with a few tries, 
sometimes requiring a restart of headsetd, it will eventually start 
working, and it usually continues to work.

My Bluetooth device is this:
Bus 003 Device 004: ID 0a5c:2101 Broadcom Corp. A-Link BlueUsbA2 Bluetooth

And my headset is the Jabra BT350.
