Having trouble with audio and video playing too speedy in Ubuntu after an upgrade? Here’s a very easy solution I finally found after much of needless deleting, reinstalling and replacing software packages.

rm -r ~/.pulseaudio
Thank you very much! The only difference with me is that I did rm -r ~/.pulse
