Hello, I have a thinkpadT43, windows xp pro. Yesterday I installed recording software, everything worked fine Then installed logitech for video cam chat, and AIM to facilitate the cam then found I had no sound. Have removed above mentioned software, and tried starting on F8 last known good setting. No sound. Have tried listening to my normal radio station, still no sound. Keyboard volume control makes normal sound, I have tried reducing volume control sound levels and then increasing them but no sound. When I connect and disconnect camera for uploading photos, no sound when there used to be. Have been into control panel and checked volume levels on audio, everything seems fine. What now? I have read about sound cards and uninstalling etc but don't know where they are or how to do it. Would much appreciate any advice. Thanks
