1) Version Of Ubuntu --- 11.10.
2) Laptop Maker is --- Toshiba.
3) Laptop Model is --- P775-S7320 with the 64 bit i7-2670 CPU.
4) Known Issue is that --- the headphones only work if I pull the plug 1/2 way out of the socket.
It was working before but I see posts referring to loss of sound after update and this might also be my problem.
It has and still does work fine in Windows 7.
Everything else seems fine.

Today it is working. I don't know if it was a temporary "reboot and now it works" type of thing or what.
