Latest pulseaudio update (1:1.1-0ubuntu15.4) increased mplayer's CPU usage to unacceptable levels - from 30-40% to 100% and dropping frames on the same video. Forcing mplayer to use alsa brings CPU usage back to normal but mplayer doesn't work with alsa directly very well... What should I do to roll back pulseaudio to the previous version - 15.3 I presume?
