Please split the patch, if possible first introduce the handling on avrcp.c and make it check if cb->set_volume != NULL then in a separate patch you can add the changes to media.c. When sending patches to userspace BlueZ please use the subject prefix e.g. PATCH BlueZ, you can also make it permanent by editing .git/config in your local tree. IMO the volume handling should be in MediaTransport not in MediaPlayer, otherwise it is quite possible that the player will change the stream volume and not just indicate which is what is recommended, in that case you would have to find what transport(s) matches the device and emit PropertyChanged on them. Our architecture is a bit different than what AVRCP suggests, because the A2DP stream may not be directly controlled by the player, it is controlled by the MediaTransport, so in case of PulseAudio multiple processes may be streaming and naturally the volume gain applies to everyone of them not just the MediaPlayer owner. -- Luiz Augusto von Dentz -- 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
