[lubuntu] Output sound is playing too fast after update (High-pitched)

view story

http://ubuntuforums.org – So the strangest thing happened after installing the recent update (on 2.2MB) the other day. Now all the output audio is playing too fast and distorting the original sound. I tried to re-install Lubuntu and also got the pavucontrol to be able to stream sound through the coaxial-output (SPDIF) to my audio system, but again, the output audio is faster than the original! What can the error be? (Hardware)
