The 7.6.1 Streaming Audio Update extension alleviates one cause of poor performance when using internet streaming media applications on
certain Macintosh computers. Internet streaming media can also be adversely affected by poor connections or poor latency to a server.
The 7.6.1 Streaming Audio Update extension can be installed on Mac OS 7.6.1, Mac OS 7.6, or System 7.5.5. The extension will not load on earlier system releases. The streaming audio improvement delivered in this extension will be included in future releases of Mac OS, and the extension will not load on releases after 7.6.1.
This extension addresses one problem specific to the following Apple products:

Technical Details
Poor streaming audio performance can occur from slow internet connections, slow servers, or while the computer is engaged in other work concurrently. On some specific revisions of the listed computer models, an additional cause of poor streaming audio performance was an interaction with the serial driver software, sound driver software, and serial hardware.
The 7.6.1 Streaming Audio Update extension changes the behavior of the serial and sound driver software to better support the demanding, real time nature of streaming audio. At times when the sound driver is busy servicing the sound hardware, extra checks are made to ensure that the serial driver can properly service the serial hardware. For some computers this results in a significant improvement in streaming audio performance.
