Jan 20 15:50:47 vvortex.ttv pulseaudio[1964]: [pulseaudio] bluez5-util.c: Information about device /org/bluez/hci0/dev_E3_28_E9_20_58_08 is invalid Jan 20 15:50:47 vvortex.ttv bluetoothd[3136]: Endpoint replied with an error: org.bluez.Error.InvalidArguments So this is really PulseAudio rejecting the connection, it probably loose track of the objects when resuming or we did not send the objects but in that case bluetoothctl would not be able to list them as well. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
