Hi Peter, If I convert all four files, which sent you, to 48K then they all play fine via PulseAudio 4.0 (no motor boating). The frequency spectrum of the 300Hz tone at 44.1K looked a lot different from the 300Hz tone generated by Audacity at 44.1K. I agree that the tone is not perfect. However, the other three files also play poorly on PulseAudio 4.0, but play fine on ALSA 1.0.25.
