I have a 2 years old Thinkpad E520. The internal microphone now work intermittently. When it works, it's fine. But all the sudden it mutes completely. And it works back a gain after some random time. The problem just repeat itself after very few days. I also have an USB microphone which is works fine on other machine but very noisy on the E520. I have window 7 pro and up to date Conexant audio driver. Any hint on what is wrong and how to fix it? Many thanks.
