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.
User68186 is right, the HDMI hogs the sound, this happens after upgrades too! Leftclick the small speaker in the upper right corner and chose "Sound Settings" Go to Output devises and check, The sound is vissible as a voobling blue line, and its still attached to hdmi, click on internal speakers, it vill start playing from the speakers, eaven if you have to select it a couble of times.
try clicking the speeker icon (kmix) in the system tray ,,,,,,,you will see the firefox,chrome, audio streem volume slider ,,,,,,,,right click the icon at the top of the slider ,,,,,you will see a move to option ,,,,point at it and select the "analogue stereo"
