Abstract
A method of adapting an automotive audio system to support surround sound comprises: configuring an application program for creation of an audio track object that specifies passthrough mode as a playback mode, wherein the application program is installed to operate under an operating system that is not configured for surround sound; configuring a framework of the operating system with a bypass past a mixer of the operating system, wherein the bypass allows surround-sound data of the audio track object to bypass the mixer; and configuring a hardware abstraction layer with a separate channel for the surround-sound data received from the operating system, wherein the hardware abstraction layer processes the surround-sound data before providing the processed surround-sound data to a decoder.

A method of adapting an automotive audio system to support surround sound, the method comprising:
- configuring an application program for creation of an audio track object that specifies passthrough mode as a playback mode, wherein the application program is installed to operate under an operating system that is not configured for surround sound;
- configuring a framework of the operating system with a bypass past a mixer of the operating system, wherein the bypass allows surround-sound data of the audio track object to bypass the mixer;
- and
- configuring a hardware abstraction layer with a separate channel for the surround-sound data received from the operating system, wherein the hardware abstraction layer processes the surround-sound data before providing the processed surround-sound data to a decoder.
A method of playing surround sound on an automotive audio system of a vehicle, the method comprising:
- creating, using an application program of the automotive audio system, an audio track object that specifies passthrough mode as a playback mode, wherein the application program is installed to operate under an operating system that is not configured for surround sound;
- bypassing, in a framework of the operating system, a mixer of the operating system by surround-sound data of the audio track object;
- processing the surround-sound data at a hardware abstraction layer of the automotive audio system;
- providing the processed surround-sound data to a decoder to generate a decoded surround sound signal;
- and
- providing the decoded surround sound signal to at least one of multiple speakers of the vehicle.
