 +**Technical Decisions**
 +   * Audio policy requires much context. Policy will be kept as (shared library) module (at least initially).
 +      * End goal will be to further isolate it further with JSON interface so that it can be relocated within a dedicated audio policy binding implementation
 +   * High-level audio binding will keep application specific context (through session) in order to enforce that applications cannot control other applications stream characteristics
 +   * We should limit the number of permissions linked to audio. Proposed initial working list could look something like: stream playback access, stream record access, priority signal (policy can affect other stream volume), audio routing changes
 +   * High-level API will need to consider format information when reporting list of potential source/​sinks for both explicit and automatic routing
 +   * HAL API will need to be extended to report device format capabilities to support the above
 +   * High-level API will provide list of standard properties to application and be extendable easily to new ones (e.g. echo cancellation). Initial working examples of that will provide access to master EQ controls on M3 DSP though Fiberdyne lower-level service for example.
 +   * Currently keeping AAAA development on DD until Master stabilizes, expected that everyone will migrate to EE for CES (likely shortly after Dresden AMM)
 +   * HAL capability to connect to vehicle signaling might be required
 +   * HAL should have provision to report URIs for additional capabilities (e.g. specific meta-data interface for VU meter display)
 +   * Specific HAL implementations will need be provided for generic dynamic device classes such as USB and Bluetooth
 +   * Discussion on handling and support for legacy applications.
 +   * Audiokinetic will show high-level binding implementation with policy application examples at Dresden AMM BoF session (HTML5 demo). Example scenarios could be: volume control based on speed, prevent phone ringing in reverse gear, audio ducking cases, hands free call interruption,​ and others from https://​​eg-ui-graphics-req-audiorouting
 +   * Desire to upgrade the audio quality of embedded demonstrations for CES. Detailed planning to occur in Dresden during audio working session
 +   * Embedded demonstrator should be connected directly to AGL signals (e.g. simulated CAN events). Different simulators/​applications can be used to simulate those signals.
 +   * Consider migrating media player back-end from QT to AGL service to MPDC or else (e.g. GStreamer based)
 +   * Advanced audio dashboard application needed. A merge of capabilities existing in Audiokinetic and Fiberdyne demonstrator is likely a good basis
 +   * Common hardware platform for demonstrator should be Kingfisher, although early availability may be a problem, we can get started with just the Renesas platform for the time being.
 +   * HALs will need to be available for different hardware (e.g. Renesas / Intel / Microchip / Fiberdyne)
 +   * Shared understanding and technical alignment between various components: high-level audio binding and policy, Fiberdyne DSP capabilities,​ Microchip Unicens, HAL and afb-controller,​ etc.
 +   * Setup MOST hardware to work in AGL environment with the help of Microchip
 +   * Collective agreement that scope of audio work necessary for secure and complete audio services is currently significantly under estimated
 +   * Definition of shared roadmap responsibilities between companies to have most components and functionality demoable at AMM Dresden in order to be able to build solid embedded demonstrator for CES 2018
