Patent ID: 8209441

Claim:
An audio transmit and receive system, comprising: an audio transmit and receive set configured to transmit audio data to and receive audio data from a processor-based host executing an application software utilizing the audio transmit and receive set, the audio transmit and receive set being further configured to communicate with the host via a port of the host; an on-line indicator associated with the audio transmit and receive set to selectively indicate an on-line status of the audio transmit and receive set when transmit audio data associated with the application software are requested by the host; and an on-line status detector in communication with the host via the port, the on-line status detector being configured to detect the on-line status based on detecting request for transmit data at the port, the detecting and the request being based on a signaling protocol associated with the port independent of the application software, the on-line status detector being further configured to activate the on-line indicator when the on-line status is detected and deactivate the on-line indicator when the on-line status is not detected.
