发明名称 Techniques for audio transducer switching under programmatic and off hook interrupt control
摘要 Techniques for configuring multiple audio transducers, including telephony devices, are provided. Audio configurations for the multiple audio input and output transducers can be selected by the user. When it is determined that a telephony device has gone off hook, the audio configuration is changed to utilize the off hook telephony device. When the telephony device goes on hook, the audio configuration can be returned to its original state. The present invention allows multiple audio input and output transducers to be used, for example, in a computer telephony client by efficiently switching between these transducers via configuration changes. According to specific embodiments, the present invention may be provided in an audio transducer switch between the multiple audio transducers and a sound card of a computer, or within a sound card itself.
