Abstract
A system includes a computer having a device driver. The device driver includes a detection module to detect an audio input. The device driver includes a selection module to send the audio input to audio hardware after detection of the audio input. The device driver also includes an emulation module to send hardware emulation information to an operating system audio application to replace feedback data received at the device driver from the audio hardware and sent from the device driver to the operating system audio application.
Claims20
A system comprising:
- a computer having a device driver, wherein the device driver includes:
- a detection module to detect an audio input;
- a selection module to send the audio input to audio hardware after detection of the audio input;
- and
- an emulation module to send hardware emulation information to an operating system audio application to replace feedback data received at the device driver from the audio hardware and sent from the device driver to the operating system audio application.
A non-transitory computer readable media comprising computer instructions, the computer instructions executable by a computer to:
- detect an audio input received from an application driver;
- send the audio input to an audio device after detection of the audio input;
- send hardware emulation information to an operating system audio application, wherein the hardware emulation information replaces feedback data from the audio device, the feedback data received in response to an audio stream sent to the audio device before the audio input is sent to the audio device.
A method comprising:
- sending feedback data received at a device driver of a computer to an operating system audio application, wherein the feedback data is received by the device driver in response to the device driver sending an audio stream to audio hardware;
- detecting an audio input at the device driver of the computer;
- sending the audio input to the audio hardware from the device driver after detection of the audio input to replace the audio stream;
- and
- sending hardware emulation information generated by the device driver to the operating system audio application to replace the feedback data after the audio input is sent to the audio hardware.
