You'll like this one...
So your fix/suggestion on PortAudio, to set the OutputParameters.SampleFormat to paFloat32 and SuggestedLatency = .2 worked to cure the dropout. Yea!
But after that, and what I thought was unrelated, was that my display cursor for my waveform picture all of a sudden got jumpy, like the resolution for the graphics got all weird. I checked lots of things regarding graphics but couldn't find the answer.
Finally I found that Stream.SamplePosition was giving me the same values over say 8512 samples worth, like the resolution went way down. That was causing the jumpy cursor. BUT...
So I went back to the stream and I commented out the SuggestedLatency = .2 line, and now the cursor is smooth again but the dropout is back. I thought the problem was related to the SampleFormat parameter, but no, it looks like the suggested latency is what cured it, but then the resolution of SamplePosition is unacceptable.
