I have a weird problem with my sound input. Namely the internal microphone of my laptop does not work with Skype, but it does work with Audacity. When I tried to configure everything, I installed PavuControl and I had to find out, that the Input Device section did not record any audio.
When I use Audacity, I can select any option for a microphone device (default, sysdefault, pulse, HDA Intel PCH: CX20588 Analog (hw:0,0) ) for it to work. When I do a Skype test call, and I run PavuControl with it, under the recording section it says the input is from Built-In Audio Analog Stereo, but it does not work. When recording in Audacity, the same thing is shown.
I use Ubuntu 14.04 LTS
