I have an old PC where I installed a Nvidia GeForce 710 and set it up like a mediacenter linked up via hdmi to my samsung TV. I'm running Ubuntu 16.04 and some times th audio get out of phase and the only way to fix it is tu run
killall pulseaudio && alsa force-reload
(or,of course, reboot the system). Can someone help me to fix this or is it just a problem of my out dated hardware?
