Public bug reported: I set the sound profile to 4.1 surround but when I turn up the volume(from the sound indicator)to high it reverts to stereo output.I think I found the reason of it being that when I increase the volume the connector in sound setting starts interchanging between Headphone and speaker(like crazy because I don't have a headphone connected) and because of that sound profile reverts to stereo output(as headphone connector doesn't support 4.1 surround profile). I have had this problem on all of my Ubuntu 11.10 installs. Is There A Fix? Thank You.
Here is is the screenshot of it http://i.imgur.com/oNUGn.png I selected 4.1 surround then increased the sound to max, the profile changed to stereo output as the connector started to interchange between speakers/headphones. I have two jacks with my speaker system. 1st is green and is for front speakers, 2 is black and for rear speaker+sub woofer. I have plugged them as usual in the cabinet and the things is that this problem doesn't happen in my Kubuntu 11.10 install or any other distros that I have installed yet. This phenomenon of the connector shuffling between speaker/headphone is a first for me on Ubuntu 11.10 and has happened on all of my Ubuntu 11.10 installs.
