I am new user of linux mint 13 Cinnamon, everything is working fine but I just noticed that my internal microphone is not working, the input volume in the sound settings is disabled for some reason and there are no devices in the "Chose the device for sound input" field. I have checked few posts in the forum which suggested to open alsamixer and adjust the gain of the microphone from there... I tried that as well but still no luck. Can anyone help???
I have hp pavilion dv6744 tx laptop... in the alsa mixer it says that my card is HDA intell and the chip is Realtek ALC268
