That causes telephony-service-indicator to stop playing notifications for new messages, as it always reuse the same instance. In dbus we see it is still trying to use an invalid session: ----- method call sender=:1.132 -> dest=core.ubuntu.media.Service serial=77706 path=/core/ubuntu/media/Service/sessions/3; interface=org.mpris.MediaPlayer2.Player; member=OpenUri string "file:///usr/share/sounds/ubuntu/notifications/Xylo.ogg" error sender=:1.485 -> dest=:1.132 error_name=org.freedesktop.DBus.Error.UnknownMethod reply_serial=77706 string "Method "OpenUri" with signature "s" on interface "org.mpris.MediaPlayer2.Player" doesn't exist " --- And the logs are being flooded with the following message: ----- Failed to get current playback position: org.freedesktop.DBus.Error.UnknownMeth od: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properti es" doesn't exist ------ AalMediaPlayerService creates both the media session and the media hub control instance in its constructor, but it does not seem to manage media-hub appearing/disappearing on dbus.
