I have a fresh Xubuntu install and I'm trying to configure the sound,
I've got a Creative Xfi Titanium series sound card
At the moment when I'm talking online in Mumble/Skype/Teamspeak etc.. my output audio is passed out as well as my input, i.e. if I was listening to music the people listening to me would also hear the music (not through my microphone, wearing a headset) and it will completely down out my voice.
As you can see I've disabled the monitor which I initially thought was the problem
All my searches for trying to solve this just turn up people wanting to hear their microphone through their speakers and not about a sound loop going the other way.
