Hello and thank you for your help. I have two jacks in front of the computer, one for headset and other for microphone. I tried to retask node 0x1f from Line Out to Internal speaker, but I got the following error: E: [pulseaudio] core-util.c: Home directory not accessible: Permission denied E: [pulseaudio] main.c: Unable to stop service: Success I had to translate the second error, because it was in Romanian, I'm not sure it 100% accurate. Nodes 0x1d and 0x20 were already set to mic and hp 2013/9/15 Raymond
