Every time I reinstall Skype on Linux I lose sound for some reason. I can hear the other side, but they can’t hear me. I fiddle with the volume settings, and after a while it starts working. This time, I paid attention and made note of how I got it working. This post is as much for me as for anyone else on Ubuntu.
Firstly, under Options > Sound Devices I switched the output device to pulse. Then I set the input device to “HDA Intel (hw:Intel,0)”. Then I opened the volume control, enabled all the devices, and set Mic Boost to about 15%. That was the critical step. Now callers can hear me.
For the first time in my Linux history, I can now receive a Skype call and have music playing at the same time. Previously, I had to kill all other sound output before answering the call and I would only see it ring, not hear it. Much progress.
Here’s a random picture from a search for Skype on flickr to brighten things up a little.
