One or more techniques and/or systems are provided for communicating between two or more drivers respectively controlling and/or managing different channels through which data is transferred between a wireless communication device and a computer system and/or between a controller of the computer system and an application of the computer system. Typically, at least one of the channels is configured to transmit time sensitive data (e.g., such as audio data) while another channel is configured to transmit time insensitive data (e.g., such as call control data). A device driver interface may be configured to provide a medium through which the two or more drivers can communicate. The techniques and/or systems find particular application with respect to Bluetooth headsets used in combination with a computer system comprising a system on chip architecture, but other applications are also contemplated.

Transference of time sensitive data between a wireless communication device and a computer system

Embodiments described herein include devices and processes for concurrently processing different audio streams with different hardware-based audio processing modes. A computing device for such embodiments may have multiple hardware audio signal processing modes capable of parallel execution. An operating system or audio stack thereof may manage audio paths or streams for audio sources producing respective types of audio signals. Which of the audio paths or streams will be connected with which of the hardware audio signal processing modes may be determined according to the types of the audio signals. A first hardware audio signal processing mode may be processing a first type of audio signal of a first audio path or stream while concurrently a second hardware audio signal processing mode processes a second type of audio signal of a second audio path or stream.
