Setting pulse to localhost before launching programPosted: December 18, 2010
On some Acer computers, the inbuilt microphone doesn’t work with Ubuntu out of the box. For programs like Skype this means that you need to use headphone.
One solution that sometimes works is to start the program with Pulse working from a local host using the following command:
/bin/sh -c "PULSE_SERVER=127.0.0.1 program-name"
