1. A computer system, comprising:

  • a memory; and

    a processor in communication with the memory, the memory comprising computer instructions executable by the processor, the computer instructions comprising;

    an isochronous audio application executable to format audio data received from a source of audio data; and

    an isochronous audio driver in communication with the isochronous audio application, the isochronous audio driver executable to convert the formatted audio data to isochronous audio data and buffer the isochronous audio data, where the isochronous audio driver and the isochronous audio application are executable within a multi-tasking operating system;

    where the isochronous audio driver is further executable to generate an isochronous audio packet that includes the buffered isochronous audio data, and the isochronous audio packet is for transmission over the switched network; and

    where, in response to only one interrupt request generated by the multi-tasking operating system, the isochronous audio application and the isochronous audio driver execute sequentially as a group without interruption to process the audio data and generate the isochronous audio packet for transmission over the switched network.
