The above shows you have your laptop docked. When docked the on board |
56 |
speakers are usually disconnected. |

It's been a very long time since I docked a laptop and my memory is not very |
76 |
reliable, but I recall fixing a similar problem by selecting a different |
77 |
output device. I don't know if you can do this from alsamixer, but you should |
78 |
be able to do it from pulseaudio, or from whatever GUI your desktop provides |
79 |
for managing audio devices. Switch over from headphones/docking station to |
80 |
speakers and you should be OK. |
