Ive always had problems with skype ususally with audio, trying to keep the usb headphones set correctly. Wha tive found is that when i see the Pulseaudio server in the audio list in Skype, and thats my only option, Skype works good,...stable and reliable.
Second issue: Its been crashing a bit, just locks up and the only thing to free it up is a reboot,..
These problems are under the new release 13.10. so concider this a bug report.
DEVELOPERS: You all need to make a good channel for people to report bugs,....
OK thats all/
