At the risk of complicating things further, here is why -- there are only 2 reasons to change the audio buffer size: 1. Performance (smaller buffers = more interrupts = more overhead/CPU usage) and 2. Latency (larger buffers, longer latency in general). If you are moving the audio buffer size up, you are trying to reduce the overhead and improve stability. It makes no sense to keep running the driver buffers lower as you achieve no latency gain since the audio buffers are larger. Conversely, if you are moving the audio buffer size down, you are likely trying to minimize the latency. To minimize the latency, you would want both the driver and audio buffer sizes as low as your system can handle (while still being matched, of course). [raised hoof falls to ground....beaten horse dies] I would recommend reviewing the well written article in the appendix of the operating manual for more information.
