Public bug reported:
I frequently find that audio streams in pulseaudio are playing at the
wrong speed. They are either a bit slow or a bit fast. To my ears I
would say that the difference in pitch is probably around one tone, or
somewhere around the ratio of 44100Hz to 48000Hz. Killing pulseaudio and
letting it get respawned usually fixes the problem.
My main audio hardware is a Focusrite Scarlett 2i2.
Example: I have just tried to play a 44100Hz MP3 in Audacious. It came
out a bit slower and flatter than it should. I ran "pulseaudio -k" and
then tried again. This time it played at the right speed.
