Comment 9 for bug 995684

If I connect the headphones so the sound comes through the headphones as the speakers built in, only to run the headphones have to start ubuntu with headphones connected, but in this case it disconnects the sound no longer goes out through speakers built into the headphones only.

I use Ubuntu 12.04 64bit in previous versions did not have this problem 9.10 and 10:04.
