I've installed Ubuntu Studio 16.04.1 LTS on my pc (ASRock X99 Taichi, i7 6800k, GTX 970, DisplayPort to iMac as monitor), my first experience with Ubuntu/Linux. I haven't installed any third party software during installation.
Whenever I play videos on youtube, the first 3-5 seconds are mute. If I pause and start playing the video from the beginning a second time, then the audio starts playing at the start. This happens every time I open a new video. Everything is in sync, but the audio always takes time to start playing. How can I fix this annoying glitch/delay? I am using the default Ubuntu Studio xfce desktop environment.
