I am currently using Skype 4.2 but I cannot sign in to the Skype network. (Internet connection is OK and so is the password). And since I'm using Ubuntu without PulseAudio (it doesn't support my soundcard), I cannot upgrade to Skype 4.3:
This version dropped support for direct Alsa support; please install PulseAudio 4.0 or greater for the best calling experience.
Is Skype 4.2 still supported on Linux? If not, how can I keep using Skype without PulseAudio?
