I have a Lenovo laptop with Soundmax Integrated Digital HD Audio. I can not hear voices through my headphone/line out jack. All other sounds come through fine, but voices are very distant and low volume. When listening to music it sounds like karaoke. I don't think there is anything physically wrong with the headphone jack since all other sound comes through both speakers. The laptop speakers work fine. When I have the laptop on the dock, stereo speakers plugged into the dock work fine. The audio settings are set to stereo speakers. There are soundmax drivers (version 22.214.171.12410) and legacy audio drivers installed. Any help?
