I am using kde:plasma version 4.13.3 in ubuntu 14.04 and it works great in most ways, but on my laptop I frequently use it as my "media center" pc. I hook it up to the TV through the HDMI port. When I do that everything works great. The sound for Netflix, VLC, Desktop Sound, Hangouts, etc.... but after I disconnect the HDMI cable I can no longer hear sound from Netflix, YouTube, or any other browser based audio. I tested this in Firefox and Google Chrome.
I am guessing this is controlled separately some how. Appreciate the help.
