I'd expect this to work the same as unplugging a pair of USB

speakers...the system sound output device should just revert back to

the built-in speakers.

Actually, it doesn't quite behave the same as USB speakers. The headset will always show up in the sound prefs until the pairing is deleted. Turning off the phone or disconnecting the baseband link is not the same as unplugging a set of speakers. Deleting the pairing is a closer match. When the headset is in use and is powered off, there is a hardware timeout that must occur before we are informed that the link has been lost. At that point, the error panel described above is presented. In the above scenario, it sounds like the link wasn't up when the device was powered. It is likely caused by the fact that the sound prefs attempts to open the current audio device when it is displayed (for the input VU meter). The audio device open / start process is synchronous and must wait for an attempt to connect to the headset to fail (~5 seconds). The fact that the process is synchronous and can't be cancelled is what causes the spinning cursor. As soon as the connection failure occurs, control returns to the sound panel and further user input is processed. - Eric [demime 0.98b removed an attachment of type application/pkcs7-signature which had a name of smime.p7s] _______________________________________________ bluetooth-dev mailing list | bluetooth-dev@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.
