A part of the problem may in fact be caused by the fact that the 'settings' (parameters) are modified by one thread, but they affect another thread (= the 'worker thread' which processes the audio samples). I didn't want to stop and restart the audio process after changing most parameters, unless really unavoidable (for example the sampling rate requires closing and re-opening the soundcard, etc). Sometimes it helps to stop and restart the 'sound thread' through the main menu ("Start/Stop"). This doesn't erase the FFT-feeding buffer, but may kick the process alive again. 73, Wolf DL4YHF .
