Problem: On certain Lenovo Laptop models (Lenovo X230 being one) the skype does not pick up sounds from the microphone properly. The sound driver is installed correctly and you can hear the sound fine from the Skype. However, the other party cannot hear your voice and when the sound does come out, it comes out very distorted.
Solution: You need to disable Microphone effects. The Built-in echo cancellation feature is interfering with the Skype’s echo cancellation feature.
1. Go to Control Panel. Click on Hardware and Sound.
2. Go to Realtek HD Audio Manager.
3. Go to Microphone, and check Disable Microphone Effect.
