Johnathan, Even without the call to set_format, I still get overruns. I also made some other changes: 1) Original code (overruns) 2) 1) minus set_format (overruns) 3) 2) with NumChannels==1 (no overruns) 4) 3) with DecimRate==32 vs 16 (no overruns) Test 3 not overrunning was no surprise since it's cuts the data in half. However, Test 4 note overrunning was a huge surprise because Test 4 pumps the same amount of data as Test 2 which does overrun. Question: Why would 2 channels at 4MHz overrun while 1 channel at 8MHz not overrun?
