Ok hopefully this is helpful:
When the DMA buffer at 64 and buffer at 256 and Sample rate at 96 Khz the Input Latency is 3.875 ms and ouput Latency is 3.740
When the DMA buffer at 64 and buffer at 128 and Sample rate at 96 Khz the Input Latency is 2.542 ms and ouput Latency is 2.406
When the DMA buffer at 128 and buffer at 128 and Sample rate at 96 Khz the Input Latency is 3.208 ms and ouput Latency is 3.073
When the DMA buffer at 64 and buffer at 128 and Sample rate at 48 Khz the Input Latency is 5.083 ms and ouput Latency is 4.813
When the DMA buffer at 64 and buffer at 64 and Sample rate at 48 Khz the Input Latency is 3.750 ms and ouput Latency is 3.479
Thanks again, Todd Hoff.
