Automotive Linux Summit Fall

From audio management perspective the In-Vehicle-Infotainment (IVI) platforms are complex featuring multiple simultaneous users in different entertainment zones with a possible large number of connected audio outputs. The new generation of IVI platforms often choose PulseAudio as their audio server. On the other hand the legacy IVI systems audio model is usually some form of audio switching matrix where sources can be freely routed to any number of sinks. This model does not map naturally to the Pulseaudio model. In this presentation Jaska Uimonen will explain how these issues are tackled in Tizen IVI stack. The solution will consist of new logical model for audio inputs and outputs in Pulseaudio and example algorithms for routing and volume control.
