I have installed skype, but I cannot make it work with my headset (corsair vengeance 1500. The problem is that whichever option I choose as microphone it will never work, and only when I select some options can I hear any sound from skype. My sound does however work for the system sounds and the voice recorder works also. I cannot enclose a picture of the options I recieve, because neither prnt screen nor shutter allows me to capture the window. I have already tried a lot of fixes like checking pavucontrol; it only states that nothing is recording audio even when I´m using the voice recorder. The options I recieve in the sound options do not show up in skype so I can´t use those options as a guideline.
Some solutions that have been proposed and worked for others are:
Go to "Input devices" and select the microphone as your input source: THIS WON'T WORK. This is how you do have to it:
Click on the "Recording" tab, showing applications capturing audio that moment (it will probably be empty).
Call the Sound Test
When answered, Skype begins capturing audio and will be shown in the "Recording" tab of the pulseaudio volume control window
Select "Input from" drop down list, select your microphone
