For some reason reason I am only able to playback one sound at a time. This means I can't do a Skype conversation and, for instance listen to music streamed from Google Play or watch a Youtube video. I can listen to VLC and YouTube or Skype/Teamspeak simultaneously.
When I open GNOME's sound applet and take a look at the applications-tab I can see "ASLA plug-in [plugin-container]" and VLC media player as seperate entries. Manipulating the ALSA plugin results in the sound-output of my browser, Skype or Teamspeak to change.
Why is it that it is either Skype (or Teamspeak) or my browser that can playback sound, but not all of them at the same time?

Any help is greatly appreciated, since I have no idea how to troubleshoot this.
