picture lag when playing sound via Displayport
Summary
I has monitor with internal speakers connected to displayport.
And when I play video in browser (Youtube) or Totem player I has picture lag from audio. And this lag get bigger with increasing computer uptime.
It means than video become playing with delay after audio begins play.
But it not happens when I switch output to headset which connected to Dual Shock controller.
A short time workaround this problem is obtained only by restarting the pulseaudio. $ pulseaudio -k
But this is very bad solution because all aplication will lose audio server and needs to be restarted for correct working.
Environment
Unless you are sure its not relevant please attach files for each command.
aplay -l

pactl list
pacmd ls
$ pulseaudio --version
