I am a bit confused about the relation between AllJoyn Audio Service and AllPlay. Is AllPlay actually funding on the AllJoyn Audio Service or is it an entirely different service? Reading through the AllJoyn AudioService documentation the AudioService seems to implement all things that AllPlay offers, so I'd assume AllPlay is based on it, but I could find no information proving this... Basically I wonder if it is possible to build an AllPlay compatible device using AllJoyn Audio Service (ie integrate AllPlay Streaming support as a sink into PulseAudio). I did a quick test checking if the AllPlay Android Jukebox App discovers an AllJoyn Audio Service Sample Sink but it does not - at least not for me. This might be some network woes or whatever, though...

Maybe someone with a proper background can enlighten the details a little?

Hi Julian,

This topic has been discussed a few times. You can read up on almost the exact same question here discussing AllPlay and AllJoyn Audio Service.

Thanks, Brian

In the [current docuentation](https://allseenalliance.org/developers/learn/base-services/audiostreaming) audio streaming is now listed as a base service and is supposed to support *"synchronized audio playback on one or many Sinks"*. I'm the guy asking the questions in the thread you mention, where the answser was that the main difference between AllPlay and Alljoyn audio was synchronization. So I must confess, I'm still confued about the relation between AllJoyn Audio Service and AllPlay....

Bottom line is that AllPlay is a proprietary software that is both HW and SW that supports best in class synchronization and multiple audio formats. AllJoyn Audio is "OK" synchronization (only synchs at the start of playback) and can only support a limited number of devices and is just unencrypted audio. AllJoyn Audio is designed for a low end speaker that doesn't demand a high end experience and syntonization is not a priority. AllPlay is designed as a solution for whole home audio with best in class specs.

Hi Brian,

sorry for the late reply. Somehow overlooked yours. I read through that thread and understand that AllPlay does some things on top of AllJoyn Audio Services. Which immediately leads to the obvious follow-up questions: Is this part of AllPlay specified publicly anywhere? Or is this closed to customers of Quallcomm?

Thanks, Julian

Speakers built with the Hardware module for AllPlay support the AllJoyn Audio Service. The AllJoyn Audio Service software is not related to the AllPlay software solution. AllJoyn Audio Service is available for anyone to use to find devices that support the Sink side of the service and start sending audio.
