The sound setting in gnome session in Precise 12.04 is similar to comment #2 and the sound setting in Unity session in Precise 12.04 is similar to comment #3 Are the sound setting in gnome and unity session different program ? Since I can select Analog Mono Duplex in Gnome sesssion in unity session , able to select Analog Mono Output + Analog Stereo Input in Mode of Output tab but in input tab, the mode only show two choices and there is no Analog Mono Duplex 1)Analog Stereo Output + Analog Stereo Input 2)Analog Stereo Output + Analog Mono Output Card #2 Name: alsa_card.pci-0000_04_02.0 Driver: module-alsa-card.c
