Note: Also, if using Google Hangouts, check that the microphone is set properly. Other machines likely require different tweaks using pavucontrol and perhaps alsamixer. These steps worked for this specific laptop. This fix survived reboot on this machine as well. We found that both alsamixer and pavucontrol were necessary to make the sound happen. When you get this set right, your sound should work for Hangouts or Skype. Use the arrow keys to select 'micboost' and lower the right side of the split bar. ((I don't believe it is necessary, but you might also have to do the same to the 'Monitor' section if you left the 'Show'(at the bottom), set on 'All Input Devices'.)) Next.Ĭlick on lock icon and change Front Left slider to 100%, and make sure Front Right slider is set back all the way to 0.
Next.Ĭhange Port to 'Microphone (unplugged)'. At bottom of screen, change to 'All Except Monitors'. In PulseAudio Volume Control (Pavucontrol), click Input Devices tab. Sound works everywhere except Google Hangouts and Skype.įix needs installation of Pavucontrol, (Software Mgr), and also you will need to tweak microphone setting in Alsamixer, (terminal). Sound issue on, Lenovo 300, sound chip:cx20751/2.
