How do I use Microsoft LiveChat LX-3000?
pavucontrol. You should be able to get it working with that.
Found an english source along with the german one I posted in comment.
so I had the problem of not hearing the sound through my Microsoft LifeChat LX-3000 which was connected to my laptop with sysop Ubuntu 14.04 LTS. I tried these two easy steps and it worked out for me.
Installing pavucontrol by running the following command line in the Terminal:
sudo apt-get install pulseaudio pavucontrol padevchooser
go to system setting,
- find item SOUND (in my laptop, sound was between printers and wacom tablet),
- in the OUTPUT section, switch the Speakers from
