I really hoped this edition of linux Mint would fix this issue, but it seems not.
The problem is this: The audio works, but when I insert my headset I can hear the sound from both my laptop speakers and the headset. As I figure it, the muting part is driver-based and not hardware-based as in older versions of sound cards.
Does anybody run linux Mint on the same type of machine as me? Does it work for you?
