I tried the cam and the digital out signal dissapears when connecting the cam. Everything is fine when i unplug it. I reinstalled Ubuntu 12.04 LTS 64 bits, same problem.
In sound settings outputs, everything dissapears except analog out when connecting the cam.
Does anyone have a clue for what i can do to fix this problem. In Windows i use Google to find the solution to problems like this. But with Linux i can not figure out witch solution to use, ending messing up things.
