apologies: Wassim, Nadim
Agenda
- from last week's minutes
- Discuss the gathered topics, who can work on which topics and which strategy
- Status update on the "access raw streams"
- AOB
- abstract of the GENIVI virtual tech summit AASIG Audio HAL workshop
Minutes
list of gathered topics on multi-zone audio management
Philippe: asked whether the participants started to think about the gathering of detailed topics for multi zone audio management analysis
- Philippe: reminds about the project timeline until the GENIVI virtual tech summit workshop scheduled on Thursday 14 My 9:00-12:00am CET
Gunnar: I started thinking about the definition of what a raw stream is
Gunnar: I would like the team to write down the topics or questions or features first and then check whether those fit in one strategy or the other or both
Suhasini: there are some termonilogy questions and concepts to align on
Gunnar: agreed, raw stream is one of them, are there others ?
Gunnar the list of prioritized topics is too high level, raw stream is at a lower level of details
Gunnar: I will create new headings on investigation topics and definitions in the wiki page created by Wassim
investigation topics added: raw streams from Android, input streams to Android
definitions added : raw stream, raw stream metadata
- /TODO/ all participants to populate the above sections with their proposals
hint: reading through the List of prioritized topics for the Audio HAL again and copy/paste whatever seems to you relevant for the work on multizone management

AASIG AAL abstract
Audio management is one important aspect and constraint for the utilization of Android Automotive for the IVI unit. During Q1, 2020, the AASIG AUDIO HAL project team has finalized the list and priorities of audio management related topics. The team has decided to investigate the software architectural design for audio multi-zone management. The following design options are investigated, (a) all audio management is inside Android Automotive, and AA manages all sinks & sources and (b) all audio management is outside Android Automotive. The team is implementing proof-of-concepts to experiment the design options. The AASIG AUDIO HAL project team will present a status report of the proof-of-concept implementation and explain the design choices made. The following next steps will be then comprehensively debated:
definition of proof-of-concept roadmap, versioning of proof-of-concept content w.r.t. roadmap milestones
early assessment of implementation TRL (Technical Readiness Level) and discussion on when and how to reaching out Google
identification of other proof-of-concepts implementation based of the list of prioritarized topics for audio management |

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.
