Hi,

Seems the test bot failed to send mail, but all tests for this patch did passed though, see https://github.com/BluezTestBot/bluez/pull/824/checks?check_run_id=2628653346.

Should I resend the patch to make test bot re-run the tests and resend result mail?

Regards,
Bao

'notify_addressed_player_changed()' expected to be called with
'player->changed_id' set to a non-zero value.

     player->changed_id = g_idle_add(notify_addressed_player_changed,
                                     player);

And 'avrcp_player_event()' relies on 'player->changed_id' to perform
Addressed Player Changed notification. However,
'avrcp_unregister_player()' calls 'notify_addressed_player_changed()'
without adding it to the main loop and set 'player->changed_id'. To
indicate addreddsed player changed for both scenarios, we set
'player->changed_id' to 1 at the head of
'notify_addressed_player_changed()'.

Fixes https://github.com/bluez/bluez/issues/142
