This Pulseaudio function is called by the Alsa functions snd_pcm_ioplug_writei()->snd1_pcm_write_areas()->ioplug_priv_transfer_areas(). Agreed? Also Wikipedia writes: " In a typical installation scenario under Linux, the user configures ALSA to use a virtual device provided by PulseAudio. Thus, applications using ALSA will output sound to PulseAudio, which then uses ALSA itself to access the real sound card. PulseAudio also provides its own native interface to applications that want to support PulseAudio directly, as well as a legacy interface for ESD applications, making it suitable as a drop-in replacement for ESD. " https://en.wikipedia.org/wiki/PulseAudio Agreed?
