I have a Lenovo Thinkpad T510, which has two built-in mic inputs. When trying to record something, the right input contributes mostly with noise, while the left one records normally (this is verified by listening to the left and right speakers, respectively). The same problem occurs when using Windows 7 or Ubuntu 11.04 (and older versions), these are the only operating systems I tried. Is this a hardware problem? Any ideas?
