I had to create a script in order to make my skype acknowledge my microphone. It's a simple code:
#!/bin/bash echo "autospawn = no" > ~/.pulse/client.conf killall pulseaudio skype
It indeed works, but I have to go to skype options -> sound devices EACH TIME I want to call someone. I don't change anything there, I just need to go there. This pc is in fact a pc made for my father, who only uses it to read news and skype me when I'm abroad. Is there a way to either open skype directly to sound devices, or somewhat make him remember my choices?
