Going through the list of prioritized topics:
- Gunnar maybe We can also check if there are some conflicting priorities, like High from one party and low from another, and we try to clear any misunderstanding about the subject or see it in a different way.
- Wassim: Maybe each one of us can fill the table offline (those who haven't filled it yet) and then we can check if there is a priority conflict.
- Wassim: for now I suggest that participants take one or two subjects that they find interesting a sort of a brain storming session
Brain storming session (recorded in PoC Milestones and Work Breakdown - in "Brainstorming about breakdown rework")
- Wassim: everyone can pick 1-2 topics that we can work on that we think it's important
- Piotr: Networked audio devices and Audio effects
- Gunnar: To clear this up, I don't really have an opinion in this area, my role here is more of a facilitator. It would be interesting however to check how we can handle the audio streams differently than from within Android Automotive (Raw Stream topic)
- Nadim: Networked audio devices and Multizones
- Wassim: Mainly keeping up with the mentioned topic but with particular stress on interfaces:
- Interfaces definition and standardization of the networked audio devices
- Audio effects related to DSP offloading however from a point of view of interfaces not only the different audio effects
Conversation about the interfaces
- Wassim: the point is that after discussing with the VHAL team, I thought to bring the same concept of interface building to AUDIO_HAL. What interfaces can we build in AUDIO_HAL that can be used by everyone. What interfaces can we standardize in AUDIO_HAL. This is why I emphasized the interfaces topics in my points.
- Wassim: @Gunnar Can you please give some example from VHAL
- Gunnar: I think this is always a target of GENIVI and it might that in VHAL we have reached this point after many discussions and contributions from different OEM and parties.
- In AUDIO_HAL, firstly there isn't a lot of interest, secondly we first have to define what we need, test it with a prototype, adjust and build interfaces and then think of standardization
- Philippe: there is for example a renewed interest in multimedia streaming standardization, this could be a nice start
- Gunnar: yes this is a nice point of course, but this is a very comlex question or topic to handle.
- Gunnar: we already had once such a topic but it the conclusion is that even if a standardaztion was to be developed, it would not have been used because most of the multimedia sources have already their applications on Android. They asked to just use the applications and the API there.
- Gunnar: in general I recommend that we : start locally (in each of our companies) and check "what do we need that AA doesn't provide", then we start developing it. If it works, we check if this should be made as a standard, then we make interfaces for it.
- Wassim: For example, since we talked about the networked audio devices, what are the main use cases:
- External amplifier controlled by Android only (for example to set priority of what to play etc)
- Audio system controlled from other ECU in the car (for example remote control)
- Audio system controlled from a server
- Wassim: Android has a solution for let's say point 1. But what about point 2 and 3? Android did not plan to contro lthe volume for example from outside Android. So why don't we have a GENIVI Standard way of doing this?
- Gunnar: yes all of this makes sense, but we need to check the different solutions before we standardize the interfaces. We could also ask for point 2 and 3 above, are these for Android only? or are they for Linux?
- and if it's for Linux, then the target audience is very large and not restricted to attendees of GENIVI AUDIO_HAL.
- Wassim: yes this is correct, we need to start first with the work and then we can go on with the next steps. i think GENIVI AUDIO_HAL is a nice platform to do this in order not to have fragmanted solutions in our industry.
- Wassim: maybe we can reduce the ambitions a bit and not target for now ISO standards.
- Wassim: rephrasing the topics of interest to not include "standardization"
Last few mentions
- The webex meeting is now a reccurent meeting and this means that the link can be used several time.

Agenda
- Slides from Wassim about the two models inside and outside of AA
- discussion of the cases/features that we are trying to solve
- checking the Audio Manager to decide whether or not it needs an update
Minutes
- 2 strategies or options:
- android provides sources and sinks
- Android controls the complete systems
- We will not discuss the need to have such options
- Basically some functions cannot be integrated to AA
- Audio sources coming from android or from external (android not aware of them)
- Each strategy has limitations and can be criticized
- Idea is to get each model and apply to it questions/cases
- Questions like safety sources, raw streams, etc.
