From RhythmBox, i have confirmed that sound output device is working fine, internal mic/external mic are working as per movement of bar in Input device section of PulseAudio.
However, when I start Skype 4.2 in 64 bit Ubuntu 13.10, neither i/p nor o/p sound devices appear to be working. PulseAudio (Local server ) is enabled under Skype audio settings.
Any guidance would be appreciated.
P.S. While answering the question, please keep in mind that I am a novice.
