* Save states: the audio frame length (samples per frame) and its fraction When the frame rate doesn't divide the sample rate, the frames alternate their number of samples; where they are in that was not in the save state, so after a load the mixer asked the streams for a different number of samples and the audio drifted from the run that never loaded (netplay CRC mismatches in the mixer state, RunAhead audio).

Everything is in the save states. Details in docs/cave-cv1000.md.
