PulseAudio can operate using two different sample-rates by configuring default-sample-rate = 44100 alternate-sample-rate = 48000. Some documentation indicate that this is supposedly good if you play some CD audio with a 44.1kHz sample-rate and some movies/musicvideos with a 48kHz sample-rate. It is not. Sound cards and HIFI equipment (when using HDMI) can only be …
