I just started using 12.10 64 bits. I have a Realtek ALC 1200 audio chip which works OK when I just play sound over my speakers, and plugging in the headphone is recognized as well.
The problem I have is that plugging in the headphone seems to shut down the physical output port (3.5mm jack) to my speakers, which causes my ancient audio set to start buzzing loudly. This happens too when I shutdown my PC, thats why I recognize it.
Is there a way to keep the port active without playing any sound on it? Essentially it needs to be in the same state as normal when the computer is not playing any sound.
I'm comfortable doing stuff in the terminal, just never had an issue like this before.
