Why Do I Have No Sound On My Lenovo Laptop. I can hear people but they cannot hear me when I speak. Make sure your audio driver is not corrupted.

Verify that the audio cable is connected to the AUDIO OUT or LINE OUT output on the Sound Card and plugged into the AUDIO IN or LINE IN of the Monitor. People often tend to start fixing the issue without truly investigating the root cause of the problem. Up to 20 cash back I cant get the sound to work on my Lenovo Think-Pad X1 Carbon Gen 1.
For more clarification you need to answer some of my queries.
There could be one or more reasons for no sound. Internal AND external headset speakers. Make sure there are no cables connected to the Headphone Jack located next to the AUDIO IN port on the monitor. Right-click the CONEXANT audio device and click Properties.
